[Purpose] This study aimed to assess the reliability of the Functional Movement Screen and explore whether this evaluation tool can predict the risks of personal injuries in Japanese soccer players. [Participants and Methods] Seventy-five Japanese college soccer players who participated in our 1 year prospective cohort study underwent a Functional Movement Screen assessment. Demographic data, athletic characteristics, and types and frequency of injuries sustained, were analyzed with the assessment results. [Results] There was no significant difference in the mean Functional Movement Screen composite scores between genders. Although the Functional Movement Screen showed excellent inter-rater reliability (0.92), low overall internal consistency (0.35) was observed. A maximum score of 3 in straight leg raise occurred in 94% of the females and was considered a ceiling effect. None of the cut-off point scores of the Functional Movement Screen were associated with the number of overall injuries, lower limb injuries, and traumatic injuries, or time to return to play. The Functional Movement Screen composite score of ≤15 represented the maximum sensitivity of 76.92% and specificity of 34.78% with 0.56 in the area under the curve. [Conclusion] Functional Movement Screen composite scores do not have sufficient sensitivity and specificity for predicting injuries in Japanese college soccer players.[Purpose] To elucidate factors that affect walking before and after direction changes and their effects on reaction time by investigating different angles of direction changes. [Participants and Methods] A total of 29 healthy young males and females participated in this study. The task was to walk along a 20-m path and perform three direction changes while walking straight walking, 45° direction change, and 90° direction change. Step length and probe reaction time (P-RT) were measured before and after the point of direction change. A two-factor repeated measures analysis of variance was applied to measure P-RT and step length before and after direction changes. [Results] A significant effect was observed for step length and P-RT immediately before and after direction changes. An interaction was also observed between the angle of direction change and the step length before and after the direction change. When compared with the straight walk, a significant effect was observed at 45° and 90° direction changes. [Conclusion] While walking, 90° direction changes are suggested to be more difficult than 45° direction changes, and 45° direction changes are more difficult than walking in a straight line.[Purpose] This study investigated the relationship between physical activity and job stress among public office workers. [Participants and Methods] We examined the levels of physical activity and job stress of 488 male public officers in Seoul-city, Republic of Korea through self-reported questionnaires. The International Physical Activity Questionnaires and the Korean Occupational Stress Scale were used to evaluate physical activity and job stress, respectively. The level of physical activity was divided into three quantiles (low, moderate, high). [Results] We found no significant difference in job stress by physical activity level. Although a positive correlation between physical activity and job stress was found in the organizational system category, no significant difference was found in the categories of the physical environment, job demand, insufficient job control, interpersonal conflict, job insecurity, lack of reward, and occupational climate. [Conclusion] There was no apparent correlation between physical activity and job stress among public office workers.[Purpose] The purpose of this study was to investigate the relationship among aging factors using the new Japanese elderly standard, early postoperative physical function, and health-related quality of life (HRQOL) in patients with gastrointestinal cancer. [Participants and Methods] We studied 94 patients scheduled for elective surgery of gastrointestinal cancer 53 males and 41 females aged 62.0 ± 12.1 years (mean ± SD). Patients were divided into three groups based on age at baseline young ( less then 65 years), pre-old (65-74 years), and old (≥75 years) groups. We measured body mass index, isometric knee extension force (IKEF), 6-minute walk test (6MWT), and Short-Form 36-Item Health Survey version 2 (SF-36) at baseline and 4 weeks after surgery. [Results] Patients 75 years or older had significantly lower IKEF and 6MWT compared to the other groups. Patients younger than 65 years had significantly greater scores on the mental health SF36 subscale 4 weeks after surgery compared to baseline. Comparatively, patients older than 75 years had significantly decreased mental health scores 4 weeks after surgery. [Conclusion] Based on the new Japanese elderly standard, advanced age appears to worsen the postoperative change of HRQOL in patients with gastrointestinal cancer.[Purpose] To compare the changes in the muscle cross-sectional area (MCSA) along the long axis of the lower leg muscles at rest and during ankle plantar flexors isometric contraction and to obtain basic information regarding the movement of lower leg muscles during ankle plantar flexors contraction. [Participants and Methods] Sixteen healthy young female participants (20.9 ± 1.2 years) were asked to sit with their ankles in a neutral ankle position. AZD9291 in vivo Images were obtained at rest and during isometric contraction of the ankle plantar flexors using gravity magnetic resonance imaging. The MCSAs of the triceps surae and tibialis anterior were measured. [Results] The middle region of the soleus muscle had a lower MCSA on contraction than at rest. In addition, the medial head of the gastrocnemius had a lower MCSA on contraction than at rest in the distal quarter. Moreover, the tibialis anterior had a lower MCSA at rest than on contraction in the middle region. [Conclusion] The area to be used as an indicator and the movement to be induced differ depending on the muscle during isometric contraction of the triceps surae.
