Background: Perceived benefits and barriers to exercise are important correlates of exercise participation. Purpose: To develop a short version of the perceived benefits and barriers to exercise scale and to examine its validity and reliability. Methods: A population-based cross-sectional study of 865 participants (age: 20-69 years old, men: 46.5%) was conducted in four cities in Japan (Koganei, Tshukuba, Shizuoka, Kagoshima). Perceived benefits and barriers scale including five benefit subscales (physical benefit, psychological benefit, social benefit, weight management, self-improvement) with 10 items, five barrier subscales (discomfort, lack of motivation, lack of time, lack of social support, poor physical environment) with 10 items and stage of change for exercise behavior were assessed by self-administered questionnaire. Results: Confirmatory factor analyses to examine the construct validity revealed acceptable fit indices (benefit scale: GFI=.980, AGFI=.951, RMSEA=.058, AIC=151.669, barrier scale: GFI=.973, AGFI=.949, RMSEA=.060, AIC=166.084). Seven of ten subscales indicated significant linear associations with stage of change for exercise behavior, criterion-related validity was revealed. The reliability of the scale was found to be good as internal consistency and inter-rater reliability. Conclusion: The short version of the perceived benefits and barriers scale developed in this study demonstrated acceptable construct validity, criterion-related validity, internal consistency and inter-rater reliability.

<p>This retrospective observational study aimed to examine the effects of playing Pokémon GO on daily steps of male college students. Twenty-five Japanese male college students (20 ± 1 years) were assigned to Control group (C, n = 11) or Pokémon GO group (P, n = 14) based on their playing Pokémon GO or not. Daily step levels were obtained from the health care app of Apple iPhone from September 2016 to October 2016. In P group, the data for the 4 weeks to determine baseline values and for the 4 weeks of playing Pokémon GO were analyzed. The steps data of C group were also analyzed in the same period of the total 8 weeks. There were no significant differences in steps at baseline level between both groups. In addition, no significant time-course changes in steps were observed in C group. In contrast, steps in P group significantly increased from baseline 8,368 ± 544 steps/day to week 1 10,028 ± 617 steps/day (P < 0.01). The changes in steps from baseline to week 1 were significantly greater in P group than in C group (1,671 ± 345 vs. -81 ± 582, P < 0.01). However, the increased steps returned to baseline level by week 2, and the values did not increase again. Therefore, our findings indicate that playing Pokémon GO increases daily steps only during one week in Japanese male college students.</p>

Walking football was born in United Kingdom around 2011, that is forbidden to running. In recent years, walking football has become increasingly popular as a sport that diverse people can enjoy together. However, it is not clarified exercise intensity and how they feel after playing walking football. We aimed to determine the intensity when playing walking football and investigated how mood change. Twenty-six men and women (18 males, 8 females) out of those who participated in walking football event agreed to the present study. Heart rate (HR) was measured using wearable device with photoplethysmography when playing walking football. Metabolic equivalents (METs) was assessed using a triaxial accelerometer worn on the waist. McGill pain questionnaire was used to assess pain sites and number. To assess change in mood, short version of physical activity enjoyment scale (sPACES) was used before and after playing walking football. Borg scale was measured before and after walking football. The HR and METs were respectively as follows; male, 111.9 ± 11.4 bpm and 4.3 ± 0.6METs; female, 118.6 ± 16.2 bpm and 4.8 ± 0.7METs. There was no significant difference between men and women in both HR and METs during walking football. The sPACES was indicated significantly positive changes in mood, and Borg scale was significantly increased after playing walking football, without increasing acute or chronic pain. The walking football is safe and moderate-intensity sports and induce positive changes in mood.

It has been reported that physical fitness of breast cancer patients is relatively lower due to the cancer treatment such as surgery, chemotherapy, or endocrine therapy. Previous studies have revealed that not only cardiorespiratory fitness but also muscle strength is lower among breast cancer patients than no disease women and these symptoms may aggravate the health-related quality of life. However, there is no study which has focused the physical fitness level in Japanese breast cancer survivors. The purpose of this study was to investigate the physical fitness level and the relationship between exercise habituation and physical fitness level in Japanese breast cancer survivors. Fifty breast cancer survivors participated in this study. Participants were assigned to either exercise habituation group (n=25) or non-exercise group (n=25). We evaluated exercise habituation using an original questionnaire and examined various physical fitness level. Body weight, body mass index, and percent body fat were significantly lower in the exercise habituation group than non-exercise group. T-score of cardiorespiratory fitness was significantly higher in the exercise habituation group than average Japanese women. These results suggested that exercise habituation is relative to body weight and cardiorespiratory fitness level in Japanese breast cancer survivors.

We aimed to investigate the characteristics of lower-limb strength and power used for lower-limb mechanical variables in rebound jump (RJ) test by using a new system (Quick Motion Analysis System), which calculates mechanical variables in real time. Thirty-three male jumpers performed the RJ test. The performance (RJ index, contact time, and jump height) and joint kinetics (joint work and joint contribution) in RJ were calculated. IAAF Scoring Tables of Athletics were used to calculate jump event performance (IAAF score). IAAF score was positive correlated with RJ index, jump height, and joint work at the ankle and hip joints. Elite jumpers achieved higher RJ performance by larger ankle and hip joint work. As performance variables, jumping height and contact time were converted to T scores, and evaluation method was proposed to use the relative merits of these values to classify athletes into four types. The IAAF score showed no differences among the four types. These results indicate that there is no relation among jump events performance and characteristics of the four types. Moreover, focusing on stiffness, based on the contact time and jump height, jumpers with a longer contact time and higher jump height type showed lower stiffness (compliant spring characteristics), whereas those with the opposite features showed higher stiffness (stiffer spring characteristics). Therefore, for evaluating lower-limb strength and power characteristics, the use of performance and joint kinetics are effective, in addition to focusing on type characteristics based on the contact time and jump height in RJ.

Recently, a standing desk is being installed as a behavior change strategy to reduce sitting time in the workplace. However, the standing posture has been suggested to decrease forehead oxygenated hemoglobin (oxy-Hb), which might impair task performances. Therefore, we examined whether prolonged standing impairs speed and accuracy of computer subtraction task associated with a decrease in forehead oxy-Hb. Nine healthy young males completed 4 × 15-min computer tasks under two conditions, i.e., sitting and standing. In the computer tasks, all subjects were required to subtract a two-digit number from a four digit number written on the paper and to input the answer to the answer colomn on the computer. Task performances were evaluated as the number of achievements and accuracy rate every 15 minutes. Moreover, oxy-Hb and deoxygenated-hemoglobin (deoxy-Hb) in the site of left forehead area and lower limb were monitored throughout the experimental period by near-infrared spectroscopy. Forehead oxy-Hb was significantly associated with the number of achievements during computer tasks (p < 0.001). In addition, forehead oxy-Hb and task performances did not differ between sitting and standing. The number of achievements of subtraction task under standing condition was significantly decreased as time proceeds. Our results demonstrate that prolonged standing might impair computer subtraction task performances irrespective of the change in forehead oxy-Hb.

To clarify the function of the vastus medialis obliquus (VMO) and longus (VML), we investigated the electromyographic properties of superficial quadriceps femoris during fatiguing knee extension task.Ten healthy male and 10 female volunteers participated in this study. The subjects performed fatiguing knee extension task at maximal effort (10 times×10 set at 60 deg/sec). Surface electromyography (EMG) was recorded from the VMO, VML, vastus lateralis(VL) and rectus femoris(RF) during isometric knee extension (knee bent at 60 deg and 30% of the maximal voluntary contraction level) with a 90-sec interval between each set. Knee extension peak torque, integrated EMG (IEMG) and median power frequency (MDF) of four muscles during each set were compared using Dunnett's test.Knee extension peak torque decreased gradually and peak torque decreased significantly starting from set 9 in male subjects, while there was no significant decrease in female subjects. IEMG from VMO and VL increased linearly. IEMG increased significantly from set 7 in VMO and set 6 in VL for both male and female subjects. Then, IEMG from both VML and RF increased significantly starting from set 9 in VML and set 8 in RF in male subjects, while there was no significant change in female subjects.MDF of VMO, VL and RF also increased significantly at timepoints similar to those showing increases in IEMG in male subjects. However, MDF of VML increased significantly from set 4 in male subjects. On the other hand, MDF did not change significantly in female subjects.As a result of this study, it was suggested that VMO and VL were facilitated to maintain target knee extension torque during fatigue. Therefore, it was considered that VML and RF facilitated the maintenance of target torque under fatiguing conditions.

The aim of the present study was to examine the validation of prediction equation of basal metabolic rate (BMR) in Japanese female athletes. The study population consisted of 122 Japanese female athletes (age 20.2 ± 1.3 years, height 162.5 ± 6.3 cm, body weight (BW) 57.4 ± 7.7 kg, and fat-free mass (FFM) 45.5 ± 5.1 kg). Body composition was estimated by using air displacement plethysmography (BOD POD System). BMR was measured by indirect calorimetry using dougras bag tequnique, and predicted BMR was calculated from different equations based on FFM. When compared with measured BMR, predicted BMR from the equation of Taguchi et al. (BMR (kcal/day)= 26.9×FFM (kg)+ 36) and equation of Owen et al. were not significantly different. Whereas, predicted values from equation of Japan Institute of Sports Sciences, National Institute of Health and Nutrition and Cunningham were significantly different from measured value. Estimation error and Total error were smaller in equation of Taguchi et al. and Owen et al., however, equation of Owen et al. had a larger estimation error in the subjects who was small body size (less than 42kg) or large body size(more than 69kg). Furthermore, newer equation of Taguchi et al. (BMR=27.5×FFM+5) was developed from the pool data (n=205) in the present study. Standard error of estimation (SEE) of this equation was smaller than the equation of Taguchi et al., and systematic error was hardly observed.In conclusion, the newer equation of Taguchi et al. developed from measured BMR of Japanese female athletes was useful to predict BMR.

This review explores novel possibilities of skeletal muscle hypertrophy mechanism based on previous studies. Hypertrophy and/or regeneration of skeletal muscles are caused by activation of satellite cells, induced by mechanisms such as growth factors and cytokines. Many unsolved problems, however, yet remain concerning signaling pathways, activated by such substances, and regulation of transcriptional factors and cell cycles.In recent years, possible involvement of not only satellite cells but also tissue-specific stem cells in skeletal muscle hypertrophy has been reported from studies made on stem cell transplantation in muscle regeneration.It has been elucidated that differentiation plasticity of tissue-specific stem cells contributes to hypertrophy and/or regeneration of skeletal muscles. Moreover, satellite cells have come to be regarded as one kind of tissue-specific stem cells, since they have been known to exhibit diversity, by their differentiating into not only skeletal muscle cells but also other tissue cells, as well as self renewal capacity.This review also summarizes findings on signaling pathways based on ligand receptor characterization. Among the various signaling pathways, focus was especially placed on the possibilities of Wnt signaling pathway and Notch signaling pathway on skeletal muscle hypertrophy, indicating that Wnt expression in adult muscle stem cells leads to regulation of skeletal muscle hypertrophy.It has also become evident that Notch signaling pathway is associated with the activation of satellites cells, and that functional decline of such signaling pathway causes a decline in the activation of satellite cells. Such functional decline of Notch signaling pathway has also been revealed as the reason for the decline of regenerative capacity of skeletal muscles due to advancing age. Further discussion on the involvement of Notch signaling pathway in skeletal muscle hypertrophy is made based on these results. As indicated above, the roles of ligands and/or receptors of canonical growth factors, signaling pathways, and transcriptional factors contributing to skeletal muscle hypertrophy were reexamined in this review, after which the contribution of tissue-specific cells to skeletal muscle hypertrophy was discussed based on the results of muscle regeneration studies. Furthermore, focus was centered on Wnt and Notch signaling pathways, both of which are attracting renewed attention, and study was made on the possibility of the involvement of these pathways in skeletal muscle hypertrophy process.

The purpose of this study was to develop prediction models of sarcopenia in 1,894 Japanese men and women aged 18-85 years. Reference values for sarcopenia (skeletal muscle index, SMI; appendicular muscle mass/height2, kg/m2) in each sex were defined as values two standard deviations (2SD) below the gender-specific means of this study reference data for young adults aged 18-40 years. Reference values for predisposition to sarcopenia (PSa) in each gender were also defined as values one standard deviations (1SD) below. The subjects aged 41 years or older were randomly separated into 2 groups, a model development group and a validation group. Appendicular muscle mass was measured by DXA. The reference values of sarcopenia were 6.87 kg/m2 and 5.46 kg/m2, and those of PSa were 7.77 kg/m2 and 6.12 kg/m2. The subjects with sarcopenia and PSa aged 41 years or older were 1.7% and 28.8% in men and 2.7% and 20.7% in women. The whole body bone mineral density of PSa was significantly lower than in normal subjects. The handgrip strength of PSa was significantly lower than in normal subjects. Stepwise regression analysis indicated that the body mass index (BMI), waist circumference and age were independently associated with SMI in men; and BMI, handgrip strength and waist circumference were independently associated with SMI in women. The SMI prediction equations were applied to the validation group, and strong correlations were also observed between the DXA-measured and predicted SMI in men and women. This study proposed the reference values of sarcopenia in Japanese men and women. The prediction models of SMI using anthropometric measurement are valid for alternative DXA-measured SMI in Japanese adults.

The purpose of this study was to investigate the effects of combined resistance training and aerobic training with protein intake after resistance training on body composition in obese middle-aged women. The subjects were 42 middle-aged women (age : 56.5±4.3 years, BMI : 26.6±2.3 kg/m2), who were classified into three supplementation groups: Protein group (PG), Isocalorie placebo group (IG), and Noncalorie placebo group (CG) by Double Blind Randomized Trial. The training program consisted of combined resistance training and aerobic training for 10 weeks, 5 times per week: twice a week in a university training room and 3 times per week at home. The subjects took the nutrient supplement immediately after each resistance training session. We measured body weight (Bw), body fat volume (Bf) by bioelectrical impedance analysis (BIA), and cross-sectional area (CSA) of muscle of the thigh extensor group (Te), flexor group (Tf), and psoas major (Pm) by magnetic resonance imaging (MRI) before and after the 10-week training period. Irrespective of group, Bw and Bf showed a significant decrease after the training period compared to before (p<0.001), and the CSA of Te muscle showed a significant increase after the training period (p<0.01). Moreover, the interaction of time×group was accepted in the CSA of Pm muscle (p<0.05), and the increase in muscle volume for PG was the highest increase among the three supplementation groups (p<0.05)(PG : 2.1±0.8 cm2, IG : 1.3±1.0 cm2, CG : 1.3±0.9 cm2). These results suggest that combined training in middle-aged obese women improves body composition, and resistance training with protein intake may increase the CSA of muscle of psoas major.
