Lukas Schwingshackl, MSc Department of Nutritional Sciences University of Vienna Vienna, AUSTRIAMedicalResearch.com: Interview with: Lukas Schwingshackl, MSc Department of Nutritional Sciences University of Vienna Vienna, AUSTRIA Medical Research: What are the main findings of the study? Lukas Schwingshackl: The results of the present meta-analyses showed that, in patients with established diabetes, aerobic training might be more effective in reducing glycosylated haemoglobin and fasting glucose when compared with resistance training. Combined aerobic and resistance training was more powerful in reducing glycosylated haemoglobin compared with aerobic training, and more effective in reducing glycosylated haemoglobin, fasting glucose and tricylglycerols when compared with resistance training. However, these results could not be confirmed when only low risk of bias studies were included. (more…)

Dr. Kokkinos: The main finding of the study is that we defined an exercise capacity threshold for each age category (<50; 50-59; 60-69; and ≥70 years of age). The mortality risk increases progressively below this threshold and decreases above it. We then calculated the 5 and 10-year mortality risk for each age category. (more…)

Xuemei Sui, MD, MPH, PhD Assistant Professor Department of Exercise Science Division of Health Aspects of Physical Activity Arnold School of Public Health University of South Carolina Columbia, SC 29208MedicalResearch.com Interview with:  Xuemei Sui, MD, MPH, PhD Assistant Professor, Department of Exercise Science Division of Health Aspects of Physical Activity Arnold School of Public Health University of South Carolina Columbia, SC 29208 MedicalResearch: What are the main findings of the study? Dr. Sui: In the present study, cancer survivors who reported performing resistance exercise (RE) at least 1 day of the week had a 33% lower risk of all-cause mortality compared with individuals who did not report participation in resistance exercise.  Further, there was an inverse relationship between resistance exercise and all-cause mortality in those who were physically active, but not in those who were physically inactive.  Although leisure-time physical activity was not associated with a lower risk of all-cause mortality, the present results support the benefits of resistance exercise and physical activity was during cancer survival.

Lee, Pharm.D., Ph.D. Assistant Professor Department of Pharmacy Practice College of Pharmacy Oregon State University/Oregon Health and Science University Portland OR, 97239 MedicalResearch: What are the main findings of the study? Dr. Lee: We found that older men taking a statin were less physically active and had more sedentary behavior. They had about 37 minutes of less moderate exercise per week. For comparison, the American heart Association recommends about 40 minutes of moderate activity 3-4 times per week. We also found that those that started using a statin during the study had the largest drop in physical activity. (more…)

Dr. Cramer: There is a number of randomized trials available on yoga for asthma. Based on those trials, there is evidence that yoga can improve asthma symptoms, asthma control, and pulmonary function in patients with asthma. However, yoga does not seem to be superior to sham procedures or breathing exercises and generally the evidence was quite weak. Yoga seems to be relatively safe in this patient population. (more…)

Dr. Khan: We wanted to find factors that lead to either an increase or decrease in risk of developing cardiovascular disease. We found that in middle aged overweight and obese women, who may not have any medical problems like diabetes, high blood pressure, high cholesterol, an increase in weight over time and the development of any of the conditions stated above, increased the risk of cardiovascular disease significantly. On the other hand, even moderate physical activity decreased the risk of heart disease, even in the presence of the above stated conditions. (more…)

Professor Bennell: In 102 people with painful hip osteoarthritis, we compared a 'real' physical therapy program involving exercise, manual therapy techniques,education and provision of a cane if appropriate to a sham physical therapy treatment that was made to look as though it was real but instead involved turned off ultrasound and gentle application of a hand crème to the hip region. Participants in both groups went to see a physical therapist on 10 occasions over 12 weeks and performed home exercises if in the 'real' physical therapy group or lightly applied the cream at home if in the sham group. Participants were followed for 9 months in total. We found that while both groups showed improvements in pain and physical function, the improvements were similar between the two groups. That is, the real physical therapy program did not show greater benefits over a sham treatment.  (more…)

MedicalResearch Interview with: Monique Francois Teaching Fellow & Research Assistant at the University of Otago School of Physical Education, Sport and Exercise Sciences University of Otago Dunedin, New Zealand MedicalResearch: What are the main findings of the study? Answer: We found that small 'snacks' of interval exercise before the three main meals lowered postprandial blood glucose and contributed to a lower blood glucose across the day. Whereas 30 minutes of continuous moderate exercise before dinner did not lower postprandial blood glucose nor mean glucose levels the exercise day or the following day, compared to exercise snacking. Six one minute intervals as walking or a combination of walking and resistance 3x per day (before the three main meals) improved glycaemic control in individuals with insulin resistance. (more…)

Luisa Soares-Miranda, PhD Research Center in Physical Activity, Health and Leisure Faculty of Sport, University of Porto Rua Dr. Plácido Costa, Porto PORTUGALMedicalResearch.com Interview with: Luisa Soares-Miranda, PhD Research Center in Physical Activity, Health and Leisure Faculty of Sport, University of Porto Rua Dr. Plácido Costa, Porto PORTUGAL MedicalResearch: What are the main findings of the study? Dr. Soares-Miranda: Modest physical activity, such as the distance and pace of walking, is important for the heart’s electrical well being of older adults. In our study, older adults that increased their walking pace or distance had a better heart rate variability when compared with those that decreased their walking pace or distance. Our results suggest not only that regular physical activity later in life is beneficial, but also that certain beneficial changes that occur may be reduced when physical activity is reduced. This supports the need to maintain modest physical activity throughout the aging process. Even small increases can lead to a better health, while reducing physical activity has the opposite effect. So, any physical activity is better than none, and more is better. (more…)

Dr. McKenzie: Our study was the first to compare and describe epidemiological patterns of basketball-related injuries presenting for treatment to emergency departments and to the high school athletic training setting using surveillance data captured from large, nationally representative samples. Specifically, we compared estimated national incidence, rates of injury and body sites injured, and diagnoses. Nationally, an estimated 1,514,957 athletes with basketball-related injuries reported to the emergency department and 1,064,551 presented to the athletic training setting. Patterns of basketball-related injuries presenting to the emergency department differ from those presenting to the high school athletic training setting for treatment, with those presenting to the emergency department being more severe. In general, injuries that could be relatively quickly assessed and more easily diagnosed and treated, such as strains and/or sprains, presented more commonly to the athletic training setting, while injuries that required more extensive diagnostic or treatment procedures, such as fractures, were treated more commonly in the emergency department.

MedicalResearch.com Interview with: Neeru Jayanthi, MD Associate Professor Medical Director, Primary Care Sports Medicine Loyola University Medical Center study MedicalResearch.com: What are the main findings of the study? Dr. Jayanthi: We surveyed a cohort of 1,190 athletes ages 7 to 18, including 1,121 for whom insurance status could be determined. Our main findings were: 1. The rate of serious overuse injuries in athletes who come from families that can afford private insurance is 68 percent higher than the rate in lower-income athletes who are on public insurance (Medicaid). 2. Privately insured young athletes are twice as likely as publicly insured athletes to be highly specialized in one sport. MedicalResearch.com: Were any of the findings unexpected? Dr. Jayanthi: The findings confirmed our hypothesis that higher-income students would be more likely to specialize in one sport, and also more likely to suffer serious overuse injuries. MedicalResearch.com: What should clinicians and patients take away from your report? Dr. Jayanthi: Specializing in one sport at an early age increases the risk of serious overuse injuries. Here are evidence-based tips to reduce the risk of overuse injuries: • Increase the amount of unstructured free play, while limiting the amount of time spent in organized sports and specialized training. Do not spend more than twice as much time playing organized sports as you spend in unstructured play. • Do not spend more hours per week than your age playing sports. For example, a 10-year-old should not spend more than 10 hours per week playing sports. • Do not specialize in one sport before late adolescence. • Do not play sports competitively year round. Take a break from competition for one to three months each year (not necessarily consecutively). • Take at least one day off per week from sports training. MedicalResearch.com: What recommendations do you have for future research as a result of this study? Dr. Jayanthi: We are doing a pilot study this summer comparing parent/child dyads of high competitive young athletes and recreationally active children with parent dyad to see differences based on sports participation of child and adult, as well as based on socioeconomic status. This may lead to a much larger study.

MedicalResearch.com Interview with: Zoe Michaleff PhD Student, Musculoskeletal Division The George Institute for Global Health Sydney NSW 2000 Australia MedicalResearch.com: What are the main findings of the study? Answer: Our study showed that a 30 minute advice session with two phone call follow ups was as effective for chronic whiplash as the comprehensive physiotherapy exercise program in which participants received twenty, one-hour individually-tailored and supervised exercise sessions over a 12-week period. While people's pain and activity improved in both treatment groups, the most important finding is that there were no differences between groups. This finding held true for all outcome measures except for two secondary outcome measures of self rated recovery (global perceived effect) and functional ability (patient specific functional scale) which were in favour of the comprehensive exercise program however the size of these effects were too small to be considered clinically meaningful.

David R. Jacobs Jr, PhD Divisions of Epidemiology School of Public Health University of Minnesota, MinneapolisMedicalResearch.com Interview with: David R. Jacobs Jr, PhD Divisions of Epidemiology School of Public Health University of Minnesota, Minneapolis MedicalResearch.com: What are the main findings of this study? Dr. Jacobs: Vigorous activity is what is well understood to improve cardiorespiratory fitness. People with high fitness are likely (based on this study) to a) Lose fitness more slowly as they age and b) To maintain sharper "thinking skills" into late middle age. I think the message of this study is primarily for the people in the low to mid range of fitness in young adulthood.  Thus, of more importance to the general population, if the people with low to moderate fitness simply do things, be engaged in family, job, community, move around, they would  be able to do better on a treadmill test such as we used.  Because those who lost less fitness over average age 25 to average age 45 had higher thinking skills at age 50, people who start moving around are likely to reap the benefit of less loss of thinking skills by average age 50.

Professor Mathieu Boniol PhD International Prevention Research Institute Lyon, FranceMedicalResearch.com Interview with: Professor Mathieu Boniol PhD International Prevention Research Institute Lyon, France MedicalResearch.com: What are the main findings of the study? Prof. Boniol: We conducted a meta-analysis of all prospective epidemiological studies on physical activity and risk of breast cancer. It includes 37 studies, so covers more than 4 million women among which more than 100,000 breast cancer were diagnosed. We showed that when comparing the most active women (about 20% of the population) to least active women (another 20% of the population), vigorous physical activity reduce the risk of breast cancer by 11%. And the good news is that this decline is irrespective of age, BMI, menopausal status, country,... It is also true for the most aggressive breast cancer (ER-/PR-). However, we also showed that this decline is not observed for women taking hormonal replacement therapies, as if these treatments (which are already infamous for poor efficacy and increasing the risk of breast cancer) would nullify any benefit from physical activity.

Answer: The main findings of the study were that despite being of similar age, the postmenopausal displayed higher blood pressure and higher blood levels of an early marker of atherosclerosis than women that had not reached menopause. Furthermore, just 12 weeks of floorball training twice a week for one hour improved the women’s conditions and reduced their blood pressure significantly. In addition, there was positive development in levels of substances vital to blood vessel function, including a decrease in the early marker of atherosclerosis. (more…)

Dr. Dunlop: We know being active, especially doing moderate activity like taking a brisk walk, is good for health. We know a sedentary lifestyle leads to health problems. What we do not know is whether or not those are two ways of looking at the same question. Does being sedentary like sitting just reflect insufficient activity OR is sedentary time is a separate and distinct risk factor for health problems. Our physical activity research group looked at national US data from the National Health and Nutrition Examination Survey.  This is an important study because they monitored physical activity using an accelerometer.  We found sedentary behavior such as sitting was its own separate risk factor for disability.

Medical Research.com Interview with: James Woodcock Senior Research Associate UK CRC Centre for Diet and Activity Research MRC Epidemiology Unit, University of Cambridge MedicalResearch.com: What are the main findings of the study? Dr. Woodcock: The cycle hire scheme in London has benefited health through increasing physical activity. This reduces risk from a range of diseases including heart disease, type 2 diabetes, and depression. These benefits were at a population level bigger than the harms the cyclists faced from injury risk or air pollution exposure.  Looking at the harms air pollution did not make much difference.  The injury risk for users of the hire bikes appears to not be higher and may be lower than that for general cycling in the same area. However, the injury risks for general cycling in the cycle hire zone were quite high and benefits for cyclists would be greater if these risks were reduced. When we broke results for general cycling in the area down by age & gender we found two interesting findings. Firstly, that the risks faced by women were higher than for men and so benefits were less clear. Secondly, when we looked at results by age group the trade-off improved very considerably as people got older and for younger people (under 30) there may actually be harms. (more…)

Dr. Juhi:  The main findings of this study including 48 RCTs with more than 4000 patients were that
  • [1] exercise therapy programs focusing on a single type of exercise were more efficacious in reducing pain and patient-reported disability than those mixing several types of exercise with different goals within the same session;
  • [2] the number of supervised sessions enhances the benefits of the aerobic exercise;
  • [3] exercise focusing on the knee extensor muscle strength only, may increase the benefits of resistance training and
  • [4] exercise seems to be effective therapy for knee osteoarthritis, regardless of age, sex, BMI, radiographic status or baseline pain.

MedicalResearch.com Interview with: Maike Neuhaus, MPsych Australian Postgraduate Award PhD Candidate Cancer Prevention Research Centre School of Population Health The University of Queensland Herston, QLD 4006 Australia MedicalResearch.com: What are the main findings of the study? Answer: Substantial epidemiological evidence shows that high volumes of sedentary behaviour – simply put  too much sitting- are linked to detrimental health outcomes such as overweight and obesity, type 2 diabetes, some cancers, and all-cause mortality. Desk-based office workers typically spend around 75% of their work hours sitting at their desks or in meetings. Furthermore, they are unlikely to compensate for these high volumes of sitting time at work with less sedentary activities outside of work. Office workers are thus a high-risk group and an important target for intervention. The Stand Up UQ study examined best-practice approaches to reduce excessive sitting in office workers. Three separate groups of administrative office workers from The University of Queensland in Brisbane, Australia, participated in this study: One group received height-adjustable workstations only; another group received the same height-adjustable workstations plus additional individual (e.g. face-to-face coaching) and organisational strategies (e.g. management consultation, staff information session) to reduce workplace sitting; the third group served as control group and maintained their usual work-practice. Results showed that relative to the control group, the group receiving height-adjustable workstations and additional strategies had a three-fold greater reduction in sitting time than the group receiving height-adjustable workstations only. These findings have important practical and financial implications for workplaces targeting sitting time reductions. (more…)

MedicalResearch.com Interview with: Anna-Christina Lauer, MD Department of Audiology and Phoniatrics Charité-University Medicine Berlin Berlin, Germany MedicalResearch.com: What are the main findings of the study? Dr. Gross: We could show that the injury rates depend on the undergraduate medical training the students attended. This demonstrates that medical undergraduatue education, especially a hands-on training, is critical in the prevention of needlestick- and sharps injuries. Also the use of safety devices has proven to reduce injury rates significantly. Given the large size of our study we could not only comfirm that needlestick and sharps injuries are still a common problem, looking at an injury rate of about 20% per year, we also learned a lot about the accident circumstances: Most accidents occur at bedside during venepuncture and intravenous cannulation. The second most common setting is the operating room, where suturing and instrument transfers can lead to injuries. Since we analyzed official reports and the anonymous surveys at the same time we could affirm an underreporting rate of more than 50%. (more…)

Department of Orthopaedics, Oslo University Hospital / NIMI / Norwegian School of Sports Sciences MedicalResearch.com: What are the main findings of the study? Answer: The main finding of the study was that exercise therapy in addition to patient education resulted in significantly higher 6-year cumulative survival of the native hip to total hip replacement compared with patient education only. Over the 6 year follow-up period the need for total hip replacement was reduced by 44% in the group who received both exercise therpay and patient education. Also, better self-reported physical function was demonstrated in the group who received exercise therapy and patient education, suggesting that the lower surgery rate in this group were due to better hip function, with or without the presence of pain.

MedicalResearch.com Interview with: Elin Ekblom Bak | Doktorand Institutionen för Medicin, Enheten för klinisk epidemiologi, Karolinska universitetssjukhuset Solna 114 86 Stockholm MedicalResearch.com: What are the main findings of the study? Answer: That we, in a large sample of 60 y old men and women, found that a generally active day life (compared with an inactive daily life) was significantly associated with a better metabolic health at baseline, and a reduced risk with 27% for a first time cardiovascular event and 30% for all-cause mortality during 12.5 years of follow up. This was seen regardless of intentional exercise. Why this is important is because the focus is often of just exercise for health benefits and longevity. Exercise is still important, but, as we saw in this study, the activity that we do during the extended hours of daily living is as important and has a significant effect on cardiovascular health and longevity. These results are in a reversed way in line with the detrimental effects of prolonged sitting (regardless exercise habits) now frequently reported in an increasing amount of research studies. This is because sedentary time mainly replaces time in daily activity, and vice versa (daily activity replace time spent sitting). (more…)

MedicalResearch.com Interview with: Chris Fritz BSs PEZZ Center for Pediatric Endocrinology Zurich, Zurich, Switzerland MedicalResearch.com: What are the main findings of the study? Answer: Targeted strength training significantly increases daily spontaneous physical activity (PA) behaviour in boys. The less active children showed the greatest increase. 102 healthy school children were randomly placed in two groups. The control group continued three PE classes per week, whereas the intervention group had two out of three PE classes replaced by an individualised strength training program. At baseline there was no difference in anthropometry, body composition and PAEE between the groups. At the end of the training intervention, we found a significant increase of upper and lower body strength in the intervention group in boys and in girls. Boys significantly increased their PA by 10%. Without taking into account the energy expenditure during the strength training, the 10% PAEE increase corresponds to a weekly bike ride of 28 miles for a child of 40 kg body weight. Or in other words, an individualised school based strength training program increases energy expenditure outside the intervention by an equivalent of about 7kg of body fat corresponding to 10kg of chocolate per year.
