MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Acute hospital admissions are a major contributor to disability in the elderly. Despite resolution of the reason for hospitalization, patients (especially those who are frail) are often discharged with a new major disability. This is a problem that providers of health care and policy makers should prioritize given the expectations of further growth of the population segment composed by old people. 

Traditional models of acute hospitalization for older adults seldom include a comprehensive approach to prevent hospitalization-associated impairment in functional and cognitive capacity. In contrast, exercise and early rehabilitation protocols applied during acute hospitalization can prevent functional and cognitive decline in older patients and are associated with a reduced length of stay and lower costs. Yet, patients with cognitive impairment or multimorbidity at baseline are commonly excluded from exercise intervention trials and only ‘conservative’ or ‘traditional’ programs (i.e., focusing on light walking while avoiding resistance training) have been typically applied to elders who are acutely hospitalized. Our intervention proved safe and effective to reverse the aforementioned impairment. We therefore propose that an individualized prescription of multicomponent exercise should become an inherent part of the routine management of hospitalized older adults.  Continue reading

MedicalResearch.com: What is the background for this study?  

Response: Musculoskeletal Pain as a result of common problems affecting the back, neck, shoulder, knee and multi-site pain is an increasing cause of reduced function and quality of life, and ever increasing demands on healthcare, Prognosis is often poor with many people reporting persistent symptoms after consulting their primary care practitioner. The likelihood of persistent and recurrent clinical symptoms may accentuate the physical, psychological, and social impacts of musculoskeletal pain particularly with the middle aged and elderly populations.  Pilates is an exercise approach that has become increasingly popular in recent years and includes over fifty different exercises to improve flexibility, balance, core strength, core stability. It can therefore can be individualised for people with different needs, preferences, musculoskeletal conditions, ages and abilities. Aligning exercise to patient’s functional needs has been linked to long-term exercise adherence.

This study investigated the personal experiences and perceptions of the impact of Pilates on the day-to-day lives of adults with a myriad of chronic MSK conditions following a 12 week Pilates Exercise Programme.The results were organised into five main themes: 1. Physical Improvements strength, core stability, flexibility and balance. 2. Pilates Promotes an Active Lifestyle and improved performance at work and / or hobbies. 3. Psychosocial benefits and improved confidence, 4. Increased Autonomy in Managing their own Musculoskeletal Condition and 5. Motivation to continue with exercise.

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: The link between sub-concussive head impacts and declines in neurocognitive function has been reported by some studies, yet refuted by others.  There is very little evidence that has been collected in children as they are sustaining these head impacts.

We initiated a multi-year study of youth football players to provide a more in-depth look at the question.  We measured head impacts using helmet sensors during the 2016 football season.  112 players age 9-18 completed a battery of neurocognitive tests before and after the football season.

We found that neither the total burden of head impacts nor the intensity of individual impacts were associated with changes in testing performance from pre to post-season.

Cleveland Clinic Lerner College of Medicine
Fuad Jubran Endowed Chair in Cardiovascular Medicine
Heart and Vascular Institute 

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We evaluated treadmill tests on over 122, 000 patients between 1991 and 2014. We aimed to evaluate impact of functional capacity (time on treadmill) on all cause mortality.

We found that there is a gradual and incremental reduction in mortality with increased exercise capacity/aerobic fitness in all age groups, sexes, and in patients with and without history of heart disease.

MedicalResearch.com: What should readers take away from your report? 

Response: Maintaining a high aerobic functional class is associated with greater risk reduction than absence of many known traditional risk factors such as hypertension, diabetes, prior history of CAD.

The risk reduction appears to follow a dose response pattern with no upper limits of benefits; patients with highest functional class benefits most. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: We need to test whether an improvement in functional class over time with training can move an individual patients from one mortality curve to a better one. 

MedicalResearch.com: Is there anything else you would like to add?

Response: Maintaining a high functional aerobic class appears to be associated with low mortality in all age groups. Patients appear to derive gain in survival even with the smallest improvement in functional class. However, when it comes to aerobic functional class as measured by treadmill exercise testing, more appears to be better.

Of course, patients should always check with their healthcare provider before starting an exercise program.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Given the evidence of the harmful effects of high levels of sitting time on health and the high proportion of time the majority of adults spend in this behaviour, particularly in the workplace, methods to reduce overall and prolonged sitting were needed.

Our SMArT Work (Stand More AT Work) programme was delivered to NHS office workers and involved brief education about the impact of sitting on health and benefits of reducing sitting, feedback on sitting behaviour, providing staff with a height-adjustable desk to enable them to work either standing up or sitting down, motivational posters and brief chats with a researcher to see how they were getting on. They received this programme over 12 months.

We found that office workers in our study spent nearly 10 hours/day sitting down, which can be bad for health, but we’ve shown that those office workers who received our SMArT Work programme had lower sitting time by around 80mins per day after 12 months compared to those who didn’t receive our programme. Those who received SMArT Work also reported an increase in work engagement, job performance and quality of life and less musculoskeletal issues such as back and neck pain, they felt less tired after a day at work, had less feelings of anxiety and lower sickness presenteeism (working whilst sick). We didn’t find any differences in the number of days absent at work though. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: There is evidence from randomized controlled trials that exercise has beneficial effects on physical fitness, fatigue, quality of life and self-reported physical function during and following cancer treatment. The magnitude of the effects, however, often appear modest, possibly because interventions rarely target patients with worse symptoms and quality of life.

Based on individual patient data from 34 randomized controlled trials, we found that exercise interventions during cancer treatment are effective in maintaining muscle strength and quality of life, regardless of their baseline values.

Offering exercise interventions post cancer treatment to patients with a relatively high muscle strength and quality of life does not appear to further improve these outcomes. For aerobic fitness, exercise interventions during treatment had larger effects in patients with higher baseline aerobic fitness, whereas all patients were able to improve aerobic fitness post treatment. Greater effects on fatigue and self-reported physical function were found for patients with worse baseline fatigue and physical function, both during and post-treatment.

Children with Emotional and Behavioral Issues May Benefit From Drumming Lessons

MedicalResearch.com Interview with:
Dr. Marcus Smith PhD Reader in Sport and Exercise Physiology University of Chichester Co-founder, Clem Burke Drumming ProjectDr. Marcus Smith PhD

Reader in Sport and Exercise Physiology
University of Chichester
Co-founder, Clem Burke Drumming Project

MedicalResearch.com: What is the background for this study?

Response: The research group first started to examine rock drumming from a scientific perspective in 1999 through collaboration with Clem Burke, drummer with the iconic band ‘Blondie’. In 2008 the Clem Burke Drumming Project (CBDP) was formed (visit clemburkedrummingproject.org for further information) where academics from different disciplines came together to not only explore the physiological demands of rock drumming but also the potential use of rock drumming as an intervention in research studies. Rock drumming is attractive to the scientist in that it is a unique activity that requires the coordination of multiple limbs to produce the required drumming pattern. Inherent demands relating to timing, tempo and volume must also be met. Therefore, the ability to manipulate these facets of drumming performance in a research setting is very appealing. In relation to potential research populations drumming has a universal fascination regardless of age, gender, culture, language competency and ethnicity. Anecdotal evidence suggests that drumming is a ‘cool’ activity that has a unique ‘language currency’ in terms of stimulating communication within and between those who can and cannot play the drums.

The impetus for our research study came from parents of autistic children contacting us to express their belief that drumming was having a positive effect on their child’s physical and psychological behaviour. A review of the literature showed a range of anecdotal evidence in support of such statements (Freidman 2000) and an increase in empirical drumming based research being undertaken (Bungay 2010). More recent studies have reported psychosocial benefits such as enhanced communication (Maschi et al. 2010; 2012), emotional processing and tension reduction (Flores et al. 2016; Maschi et al. 2010; 2012), group cohesion and connectedness (Blackett et al. 2005), concentration, psychomotor coordination and posture (Chen et al. 2017). The majority of this work was undertaken with adolescents with very little work focused on younger age groups. Continue reading

Physical Activity Could Reduce Risk of Parkinson disease, esp. in Men

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Parkinson disease (PD) is the second most common neurodegenerative disease affecting approximately 10 million people around the world. To date, the cause of PD remains poorly understood. It is reported that 90% PD cases have no identifiable genetic cause. What’s worse, few therapeutic advances for the treatment of PD have been made in the past decades. Nevertheless, growing prospective longitudinal studies shed lights on the potential beneficial effect of lifestyle factors on reducing the risk of developing Parkinson disease. In this study, we performed a a dose-response meta-analysis of more than half a million participants.

We found that physical activity, particularly moderate to vigorous physical activity, could significantly reduce PD risk.

Our Brains Are Hardwired To Prefer the Sofa to the Gym

Brain Behaviour Laboratory
University of British Columbia, Canada

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: For decades, society has encouraged people to be more physically active. Yet, despite gradually scaling up actions promoting physical activity across the years, we are actually becoming less active. From 2010 to 2016, the number of inactive adults has increased by 5% worldwide, now affecting more than 1 in 4 adults (1.4 billion people). This context raised the question: Why do we still fail to be more physically active?

Our hypothesis was that this failure is explained by an “exercise paradox” in which conscious and automatic processes in the brain come into conflict. To illustrate this paradox, you can think of people taking the elevator or escalator when they go to the gym, which does not make sense. This non-sense, this paradox, could be due to the fact that their intention to exercise come into conflict with an automatic attraction to resting in the elevator.

Craig Pulling. MSc, PGCE, BA (Hons), FHEA
Head of Physical Education
University of Chichester

MedicalResearch.com: What is the background for this study?

Response: Successful perceptual-cognitive skill in team-sports such as football requires players to pick up task-relevant information during the control of action in complex and dynamic situations. It has been proposed that players could perform visual exploratory activity (VEA) to be able to recognise important cues in the playing environment. VEA is defined as:

“A body and/or head movement in which the player’s face is actively and temporarily directed away from the ball, seemingly with the intention of looking for teammates, opponents or other environmental objects or events, relevant to perform a subsequent action with the ball” (Jordet, 2005, p.143).

Research has suggested that VEA is an important facet of skilled performance in youth and adult football. However, it is currently unknown whether such evidence is commensurate with the views of coaches and whether coaching practices are utilised to develop VEA in training.

In order to further current understanding on VEA and coaching practices, the present study developed an online survey to examine:
(i) when VEA should be introduced in coaching;
(ii) how VEA is delivered by coaches and
(iii) how coaches evaluate VEA.

Further, this study aimed to explore whether distinct groups of football coaches existed who differed in their approach to the delivery of VEA training and, if so, whether there were differences in the demographics of the coaches across these differentiated groups.

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Falls in older adults have long been a significant healthcare problem associated with loss of independence, premature morbidity and mortality, and considerable financial strain on individuals and healthcare systems. With the demographic impact of the Baby Boom generation aging into retirement, this issue is becoming even more critical. Among potential prevention strategies, exercise has been proposed to be beneficial. However, establishing what types of exercise are suitable to the task has been problematic. More importantly, identifying differences in the effectiveness of various exercise approaches has been lacking.

Leg cycling and electrical muscle stimulation for the critically ill? Still many peaks to climb up

Thierry Boulain, M.D.
Médecine Intensive Réanimation
Centre Hospitalier Régional
Orléans, France

MedicalResearch.com: What is the background for this study?

Response: Critically ill patients may suffer terrific muscle wasting during their intensive care unit stay. In most patients, particularly those with sepsis or other high inflammatory states, this is due to proteolytic pathways runaway that may persist as long as the cause of inflammation has not been eliminated. What is more, forced rest, as the one imposed to severely ill patients who need sedation to tolerate artificial respiratory support also induces muscle deconditioning and mass loss. In short, the more you are severely and acutely ill, the more you breakdown your muscle proteins and use the catabolic byproducts to fuel the rest of your organism. As a result of this sort of autophagy, intensive care unit survivors may have lost tens of muscle mass kilograms at discharge, to the point that they have lost all or parts of their functional autonomy. The personal and social burden is considerable as muscle weakness may persist several years after hospital discharge.

In the 2000’s, physiotherapy and early rehabilitation during intensive care have emerged as a way to counteract the autophagic muscle wasting and help patients to speed up their return to functional autonomy. Therefore, a standardized early rehabilitation that consists in early muscle exercises, systematic lowering or interruption of sedative drugs dosages to allow prompt patient’s awaking, early transfer to chair and early first walk try, has become the standard of care. However, to what extent, when and how muscles should be exercised during the intensive care unit stay in order to optimize the positive effects of rehabilitation remains a nearly blank clinical research area.

In-bed leg cycling and electrical muscle stimulation, each for their part, have shown encouraging results. In our study, we sought to know if the very early combination of both could improve global muscle strength in survivors at intensive care unit discharge.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Recent research has shown that while physical activity is associated with reduced risk for many cancers, it is associated with an increased risk for melanoma. We are not sure why this is the case, however, we have noticed that popular gym chains (e.g., Planet Fitness) often offer tanning beds, which are carcinogenic.

We surveyed over 600 people who had used a tanning bed at least once in their life to see how many had used tanning beds in gyms. About one-quarter had used tanning beds in gyms and those folks actually tanned significantly more than people who had not tanned in gyms.  Gym tanners were also more likely to show signs of “tanning addiction.”  We also found an association between tanning and physical activity, such that the people who were the most physically active were the heaviest tanners.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The human body contains many billions of bacteria cells, and the type of bacteria in your gastrointestinal tract (termed gut microbiota) has been linked to certain diseases.

Most of your gut microbiota falls into two categories: Firmicutes (F) or Bacteroidetes (B). The relative gut F/B ratio has been used to assess microbiota health. Our study was the first to examine potential relationships among F/B ratio and cardiorespiratory fitness, body composition, and diet in healthy young men and women

We recruited 37 healthy adults to undergo a battery of physiological tests and collected stool samples to analyze their gut F/B ratio using qPCR.

We found that F/B ratio was significantly correlated with cardiorespiratory fitness, but with no other variables. In fact, this correlation was so strong that a person’s fitness level explained ~22% of the variance in their gut bacteria composition. Continue reading

MedicalResearch.com: What is the background for this study?

Response: Over the years, it has become increasingly evident that impaired capacity to increase heart rate during exercise and reduce heart rate following exercise are important predictors of all-cause and cardiovascular mortality. A person’s capability to regulate their heart rate is the result of complex interactions of biological systems, including the autonomic nervous and hormonal systems. Prior work has demonstrated that genetic factors significantly contribute to variations in resting heart rate among different individuals, but less was known about the genetic factors modulating the response of heart rate to exercise and recovery.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is well-known that family background and parents’ investment in their children has a big impact on a number of outcomes, including how well people do at school, the jobs they get, and how they spend their leisure time. It is also known that it is middle-class parents who tend to work particularly hard to make sure their children get on in life.

This research starts to question whether parents’ investment in their children’s organised activities is having the desired impact. Parents initiate and facilitate their children’s participation in organised activities as it shows that they are a ‘good’ parent and they hope such activities will benefit their children in both short-term (keeping fit and healthy, developing friendship groups) and long-term ways (getting jobs, having lots of opportunities in the future).

The reality, which has been highlighted in this research, is that while children might experience some of these benefits, a busy organised activity schedule can put considerable strain on parents’ resources and families’ relationships, as well as potentially harm children’s development and well-being.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Scientists and clinicians have considered the possibility that higher intensity aerobic and muscle strength training might have a beneficial effect in preventing dementia or slowing the progression of cognitive impairment in those who have dementia.

The hypothesis has come mostly from animal research.

The main findings of our research which used a large sample and high quality methods was that higher intensity exercise, whilst possible, did not slow cognitive impairment. Neither did it have an impact on the functional and behavioural outcomes for people with dementia. It was a substantial commitment for people to participate in the programmes, although many enjoyed the experience and their physical fitness improved.

Postgraduate researcher
Physical Education and Sport Sciences Department
University of Limerick, Ireland. 

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Depression is prevalent, burdensome, and often comorbid mood disorder that is associated with other poor health outcomes. Exercise training interventions have demonstrated comparable efficacy for depressive symptoms to frontline treatments, such as antidepressant medications and behavioral therapies.

However, the evidence to date has primarily focused on findings from studies of aerobic exercise training like jogging, running, and cycling. Our work is the first quantitative summary of the effects of resistance exercise training (RET), or weight lifting and strength training, on depressive symptoms, and the influence of variables like participant characteristics, features of the RET, and the methods that were used in studies on the antidepressant effects of RET.

The main finding was that resistance exercise training significantly reduced depressive symptoms among adults regardless of their health status, the total prescribed volume of RET (e.g., how much the participants were supposed to exercise), or whether or not strength was significantly improved by the RET intervention.  Continue reading

Yoga Breathing Really Does Help You Focus – Namaste!

“Open Space Yoga Hawaii” by Open Space Yoga Hawaii is licensed under CC BY 2.0
Michael Christopher Melnychuk PhD candidate
Trinity College Institute of Neuroscience
Trinity, Dublin 

MedicalResearch.com: What is the background for this study?

Response: Practitioners of yoga have claimed for some 2,500 years, that respiration influences the mind. In our study we looked for a neurophysiological link that could help explain these claims by measuring breathing, reaction time, and brain activity in a small area in the brainstem called the locus coeruleus. We chose to focus on the locus coeruleus because this area and the chemical it produces play intimate roles in both attention and respiration.

The locus coeruleus produces noradrenaline and releases it to the entire brain. This neurotransmitter functions as an all-purpose action system. When we are stressed we produce too much noradrenaline and we can’t focus. When we feel sluggish, we produce too little and again, we can’t focus. There is a sweet spot of noradrenaline in which our emotions, thinking and memory are much clearer.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Throwing injuries are common in baseball and can be caused by excessive pitch counts, year-round pitching, and pitching with arm pain and fatigue. Despite the evidence, pitching injuries among high school players have not decreased. With a multitude of research in overhead throwers, yet the volume of overuse throwing injuries not decreasing, our team suspected there was a missing workload factor in baseball pitchers. Therefore, our team conducted research to determine whether an important factor was being overlooked: volume of pitches thrown during warm-up between innings and bullpen activity in high school varsity baseball pitchers.

In the study, our team counted all pitches thrown off a mound during varsity high school baseball games played by 34 different high schools in North Central Florida during the 2017 season. After counting nearly 14,000 pitches in 115 pitch outings, our team found that 42% of the pitches thrown off a mound were not accounted for in the pitch counts, and that there is a large variability of bullpen pitches being thrown from pitcher to pitcher. Even with a greater focus on pitch counts as a way to prevent injuries, a substantial number of pitches are going unaccounted for in high school players as part of warm-up and bullpen activity.

Response: Ketogenic diets are popular. They are very low in carbohydrate, with moderate protein and large amounts of fat. They are popular for weight loss but definitive studies of this are lacking.

We tested the effects of a ketogenic diet on high-intensity exercise performance, such as sprinting. The result showed that the ketogenic diet was harmful to performance, reducing performance by 6 – 7% when compared to a high-carbohydrate diet.

Dept. of Medicine, Montreal Heart Institute, Montréal, Québec, Canada

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Prior scientific reports have discussed the association between major sporting events and cardiovascular events, irrespective of the sport.

Ours is the first to report an increase in hospital admission rates for heart attacks in men younger than 55yo in the day following a hockey game.

MedicalResearch.com: What should readers take away from your report?

Response:  Emotional stress and lifestyle habits/behavioural patterns surrounding the spectatorship of hockey (i.e. drinking, unhealthy eating patterns, etc.) might make some Hockey (sports) fans more susceptible to heart attacks. We report a statistically significant increase in the incidence of heart attacks in young men watching the sport. This was an association that we manage to document but not an actual causal relationship. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response:  (1) Ascertain causality: Document that the “watching/attending a hockey game” was indeed an activity that the patient presenting with a heart attack did indeed do; (2) randomize sports fan to lifestyle changes and/or stress management strategies to explore if there is a decrease in cardiovascular events around the time of a sporting event. 

MedicalResearch.com: Is there anything else you would like to add? 

Response:  (1) I am a hardcore, diehard (no pun intended) Montreal Canadiens fan, which motivated me to perform this analysis; (2) We accounted for the effect of harsh winter conditions as a potential confounder of the increase in hospital rate admission for heart attacks; (3) we were quite surprised that victory, instead of defeat, lead to an increase in events; (4)  I have to conflict of interest to declare.

 Response: The 2008 Physical Activity Guidelines for Americans recommends adults do 150 minutes/week of moderate intensity physical activity (PA) in increments of at least 10 minutes at a time. However, there is limited epidemiologic evidence supporting the use of the 10-minute increment and whether shorter increments (for instance walking up the stairs) can also be beneficial for health in adults. We looked at accelerometer-measured physical activity in roughly 5,000 adults (40 and older) representative of the US population and followed them prospectively (over 7 years) to determine whether physical activity accumulated in 10-minute increments, but also accumulated in shorter bursts, were associated with lower risk of death (mortality data came from the National Death Index).

MedicalResearch.com: What is the background for this study? What are the main findings? 

– The benefits of fitness are well know, but it was unclear whether the benefits applied to those with severe obesity.  This is even more important give that the health risks associated with severe obesity are exponentially higher than in mild obesity.  Fitness in this study was defined as the top 80% of a normal population.This means that unfit is the bottom 20%.  In the past, research has shown that this threshold of fitness is associated with the biggest health benefits.

– We see that 40% of individuals with mild obesity are fit, while 11% of those with severe obesity are fit.  Individuals with high fitness had no differences in health risk, despite the large differences in obesity (~50-100 pounds).  Conversely, those within the unfit group did have significantly higher glucose, blood pressure and lipids with higher obesity levels.

In other words, fitness was able to protect individuals with severe obesity from many of the expected negative health consequences.  Continue reading

Swearing Makes You Stronger @#%^&!

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We had previously found that most people are able to tolerate having their hand in ice cold water for longer if they are repeating a swear word compared with repeating a neutral word. In these studies we have also reliably seen an increase in heart rate when swearing, indicating that activation of the fight or flight response is most likely to be what brings about the pain tolerance effects of swearing.

This latest study was designed to see if fight or flight effects of swearing would produce increase performance of physical power and strength tasks. We showed that swearing aloud can give people a boost in terms of physical performance. However, We expected that the effect would be brought about via the fight or flight response (i.e. elevated autonomic nervous system arousal), which is associated with increased adrenalin. But none of the biological measures that we took (e.g. heart rate) were  consistent with that. There was no evidence of a fight or flight response. So perhaps the effect is more psychological, perhaps associated with pain relief from swearing, or else a general disinhibition brought about by swearing in which people just “go for it” a little harder.

MedicalResearch.com: What should readers take away from your report? 

Response: People already know to turn to the register of the swear words when they really need to succeed – look at cyclists powering up hills muttering oaths under their breath! In some ways we have verified verified objectively what is a well known way to get a boost. People can partake of swearing knowing that there is evidence that it can help them with physical performance.  

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: We are currently assessing the effects of swearing on a range of common exercises such as sit ups and push ups. we also intend to assess effects of swearing on physical performance that is less dependent on strength and power such as tasks requiring dexterity or co-ordination (e.g. dancing).

MedicalResearch.com: Is there anything else you would like to add?

 Response: The research was unfunded research carried out by student volunteers at LIU Brooklyn and Keele University. I’d like to say a big thank you to the student volunteers – both investigators and participants!
