Effects of marine oligomeric polyphenols on body composition and physical ability of elderly individuals with sarcopenia: a pilot study.

PURPOSE: We aimed to identify the effects of marine oligomeric polyphenol (MOP) intake in elderly individuals with sarcopenia. METHODS: Older adults (aged 65 years or older) were recruited based on the diagnostic criterion for sarcopenia and were randomly assigned to the MOP intake group (n=10) or the placebo (PBO) intake group (n=10). To determine the effect of MOP intake received for four weeks, the pre- and post-intake body composition (weight, skeletal muscle mass, and bone density) and senior fitness tests were assessed. RESULTS: Our results showed there were significant differences in the skeletal muscle mass (p=0.039), bone density (p=0.020), fat-free mass index (p=0.026), and 2.4 m up and go test (p=0.001) between pretest and post-test. There was a significant difference between the pre-test and post-test and an interaction effect for the one-leg stand test (p=0.010 and p=0.049, respectively). However, there were no significant differences in body fat percentage, calf circumference, grip strength, or the chair rise test. CONCLUSION: Some variables exhibited significant differences in the pre- and post-assessments, and there was an interaction effect for the one-leg stand. However, this was insufficient to prove the effectiveness of MOP intake in improving sarcopenia. Therefore, additional studies are essential to examine the effects of MOP intake and exercise intervention on the body composition and fitness of patients over a longer period.

Sports injury type and psychological factors affect treatment period and willingness-to-pay: Cross-sectional study.

This study aimed to describe the sport injuries of elite collegiate athletes, and to examine the influence of career length, past injuries, and psychological factors on the treatment period and willingness to pay (WTP) for treatment.A survey was conducted among students of the Department of Physical Education, Korea National Sport University. Results were interpreted through frequency analysis and multiple linear regression analysis.All students currently in training (n = 624, mean age 21 ±â€Š2 years) participated in this study. 12-month prevalence of sports injuries was 56%. The locations of the most common and severe injuries were the knee, ankle, and back. The most frequent types of common injury were sprain, ruptured ligament, and bruising. The location of injuries varied according to the sports discipline. The treatment period was influenced by sports discipline, career length, location, and type of injury, and fear of further injuries. Treatment period was associated with the reason for fear of injuries, and WTP was influenced by fear of further injuries.Our study suggests that specific management plans for athletes based on disciplines, past injuries, and their emotional responses to previous injuries are required for rehabilitation and return to sports following treatment.

Prediction model for utilization of complementary and alternative medicine for sports injuries among Korean elite collegiate athletes.

BACKGROUND: The purpose of this study was to describe the use of complementary and alternative medicine (CAM) services by Korean elite collegiate athletes and to examine the factors influencing the utilization of CAM, or Korean Medicine (KM). METHODS: Students in Korea National Sport University (KNSU) enrolled and in training during August to December 2017 completed the survey. Data from the survey was analyzed through path analysis. RESULTS: Students who were training in the Department of Physical Education, KNSU (n = 624, 70% males, mean age 21.3 ± 1.2) participated in this study. 15% of the respondents chose KM clinics for sports injuries, a higher rate than that of the general population, and 44% of KM interventions involved acupuncture. In the path analysis, sports injuries were positive predictors for utilization of medical services and the perception of KM, and KM utilization and the perception of KM were positive predictors of the willingness to receive KM treatments. CONCLUSIONS: The use of KM such as acupuncture was relatively high in elite collegiate athletes. The perception of KM and willingness to receive KM treatments were mediated by previous KM experiences. A higher accessibility towards KM treatments are necessary.
