The purpose of this study was to examine the effects of exercise order of combined aerobic and resistance training into the same session on body composition, muscle strength and arterial stiffness in the elderly. Thirty-one elderly subjects （70.5 ± 3.5 years） were randomly assigned to 3 groups; AR： aerobic before resistance training, RA： resistance before aerobic training and CON： no training. Subjects trained 2 times per week for 10 weeks. Resistance training consisted of 3 sets of 8-12 repetitions for 5 different exercises, 70%-80% of one repetition maximum （1RM）. Aerobic exercise consisted of cycling at 60% of heart rate reserve （HRR）. Significant interaction effects were observed in body fat percentage （P 〈 0.01） and 1RM （P 〈 0.01）. However, no significant differences were observed between AR and RA. In contrast, pulse wave velocity （PWV） significantly reduced in the RA （8.8± 2.1 m/s to 7.6 ± 1.9 m/s, P 〈 0.05）, while PWV increased in the AR （7.9 ± 2.8 m/s to 10.0 ± 2.6 m/s, P 〈 0.01）, and there was significant difference between AR and RA （P 〈 0.05）. In conclusion, no effects of the exercise order were observed in body composition and muscle strength. However, aerobic exercise after resistance training reduced arterial stiffness and difference of exercise order was observed.展开更多

Evaluations of positive and negative aspects for subjective well-being are needed. Elderly subjects were intervened through a 6-month complex-type program combining amusement and exercise and its influences on subjective well-being and physical and physiological functions were investigated. Methods: Subjects in this survey were 37 healthy elderly females living in M city, Hiroshima Prefecture (age: 69.7 ± 5.9 years old), and the survey was performed between September 2016 and March 2017. The complex-type program comprised amusement and exercise programs. The survey was performed at 4 time points during the intervention period: before the intervention and 1, 3, and 6 months during the intervention. Subjective well-being (Japanese version of the Subjective Well-being Inventory (SUBI): Mental health scores, Mental fatigue scores), salivary amylase levels, and the locomotive syndrome risk test (two-step test, stand-up test, and 25-question risk assessment) were surveyed at each time point. Regarding the duration of the intervention as a factor, changes in salivary amylase levels were analyzed using repeated measures one-way ANOVA and SUBI was tested using the Friedman test (EZR Ver 1.32). In addition, the relationship between the locomotive syndrome risk level and duration of the intervention was examined using Fisher’s test. Results: SUBI and the locomotive syndrome risk level significantly differed with time during the intervention. Slight changes were observed in salivary amylase levels during the intervention. Conclusion: The present results suggest that the complex-type program promoted interactions among community-dwelling elderly subjects and positively influenced the maintenance of and improvements in physical and physiological functions. These changes may be associated with favorable influences on the positive and negative aspects of subjective well-being.展开更多

Methods: Forty-five obese and eighty-seven non-obese older subjects were recruited and their habitual factors that may contribute to obesity were assessed. Intakes of food by food-group in the obesity and non-obesity groups were checked using a visual type presentation of model nutriational balance chart (MNBC). Results: Average intake ratio of food relative to ideal food intake was significantly higher in the obesity group than the non-obesity group. The relationship of obesity and exercise or habitual activities was not significant. Conclusion: Food intake is a primary factor of obesity but regular exercise or habitual activities is not a key factor for obesity in older subjects. Since exercise habit is difficult to achieve in older subjects, particularly those who are obese, food control using the present visualtype MNBC would be one strategy forthe management of obesity.展开更多

To examine the effects of facial isometric exercise on subjective stress and oxidative stress/antioxidant capacity. <strong>Methods:</strong> In this study, we included 13 participants (6 males, 7 females;average age, 44.8 ± 19.6 years;age range: 20 - 74 years) who were exposed to constant temperature and humidity in a room. Fifteen minutes after entering the room, the force was measured before and after facial isometric exercise of the target muscles: upper lip levator, small zygomatic, large zygomatic, levator animus, laughing, buccal, muzzle, mental, temporal, masseter, and cervical muscles), and further evaluated by comparing the facial isometric exercise group and control (non-facial isometric exercise) group (crossover test). <strong>Results:</strong> Subjective stress significantly improved by 8.7 ± 16.3 in the facial isometric exercise group, and no significant difference in oxidative stress level was observed in both the groups. However, the antioxidant capacity significantly increased by 126.8 ± 168.1 μmol/l in the facial isometric exercise group. <strong>Conclusion:</strong> The results of this study suggest that facial isometric exercise is an exercise therapy that can provide mental stability and antiaging effects due to improvement in subjective stress and biological antioxidant potential.展开更多
