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. Whether you work remotely from home or in an office environment, it may also be good to invest in new Office Furniture. This could also help combat the issue of back and neck pains that you may be experiencing.

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. (more…)

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.

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

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?
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.

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.

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. (more…)

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.

- 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.

MedicalResearch.com: What is the background for this study?
Response: Previous studies have shown that exercise-based injury prevention programmes can reduce the number of sport injuries. However, no previous study investigated the prevention of football (soccer) injuries in children under the age of 14 years [1], even though the number of football players under 14 years of age could be estimated as around 15 million worldwide. In comparison, only about 100,000 players, so 150 times less, are considered professional players (earning enough money to live from playing football). The large number of children playing football and the fact that every year about 10% of these players sustain an injury, indicates the relevance of injury prevention in this population.
Based on the existing “11+” programme (that has been designed for players from the age of 14 years onwards) and our epidemiological data on injuries in football players under 14 years of age [2, 3], we developed and pilot tested an injury prevention programme for 7- to 13-year-old children (called “11+ Kids”) with an international group of experts.[4]
We designed the present cluster randomised controlled trial to evaluate whether the “11+ Kids” programme reduces the incidence of injuries in children’s football.

MedicalResearch.com: What is the background for this study?
Response: People engaging in intense exercise often take antioxidant supplements, such as vitamin C and/or E or antioxidant-enriched foods, before and after exercise in the anticipation that these will help reduce muscle soreness. In a new review published in the Cochrane Library we looked at the evidence from 50 studies. These all compared high-dose antioxidant supplementation with a placebo and their participants all engaged in strenuous exercise that was sufficient to cause muscle soreness. Of the 1089 participants included in the review, nearly nine out of ten of these were male and most participants were recreationally active or moderately trained.
