Methods: Twenty-three older women (61.6 ± 6.7 years; 74.2 ± 12.6 kg; 156.2 ± 5.9 cm) were randomized to a group that performed the exercises from multi-to single-joint order (MJ-SJ, n = 10) or a group that performed the exercises from single-to multi-joint order (SJ-MJ, n = 13). Both performed the same RT program (7 exercises, 3 sets of 10-15 maximum repetitions, twice a week, 16 weeks). Following the RT program, participants detrained for 16 weeks. Muscular strength (handgrip strength test), flexibility (sit-and-reach test), and functional capacity assessments (30-s arm curl, 30-s stand chair, 10m walking, getting up and moving) were carried out pre-training, post-training and post-detraining. Results: Results indicated that the effects of detraining do not depend on the manipulation of EO. Maintenance of benefits obtained from the RT program was observed only for flexibility, where both groups had higher scores compared to pre-training (MJ-SJ = 11%; SJ-MJ = 24.4%). Conclusion: We conclude that detraining in older women can compromise previous gains made in muscular strength and functional capacity.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"157 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83608203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The International Olympic Committee has proposed the concept of relative energy deficiency and sounded warnings about the importance of energy intake commensurate with energy expenditure due to exercise. However, it has been suggested that it is difficult to assess this energy intake and consumption in sports. Therefore, this study screened male volleyball players for relative energy deficiency, measured their energy expenditure using accelerometers, and examined the usefulness of accelerometers in sports settings. Methods: The subjects were 10 males who belonged to a working volleyball team. Their height, weight, body fat percentage, lean body mass, basal metabolic rate, hemoglobin concentration, and bone density were measured before early morning practice. To measure activity, players were asked to wear an activity meter during practice time. Result: Screening assessment standards have not been presented in Japan. Therefore, we used the value of adult BIM < 17.5 kg/m 2 used by the American College of Sports Medicine as the first stage of screening for available energy deficiency. No player had a BMI of < 17.5 kg/m 2 . In addition, no athlete had a hemoglobin concentration of < 13.0 g/dl. Discussion: All athletes measured in this study answered that they did not know their own daily energy consumption. Considering the paucity of data on male volleyball players and the concern about the lack of available energy, it is considered effective to prevent the lack of available energy by proactively measuring it if an activity meter is available for the sport.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83351622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether HIIT is more effective in improving cardiorespiratory fitness and exercise capacity in older adults compared with Moderate-Intensity Continuous Exercise (MICT) remains controversial. This review and META analysis assessed the outcomes associated with HIIT on cardiorespiratory fitness and exercise capacity in older adults by searching five electronic databases (PubMed, Embase, SPORTDiscus, Scopus, and Cochrane Library) (built to July 2022). Relevant studies were included using the Cochrane Risk of Bias Assessment Tool; statistical analyses were performed using REVMAN software. HIIT significantly improved VO 2max (HIIT vs. MICT) (weighted mean difference = 1.80, 95% confidence interval: 1.25-2.35, p < 0.001) and maximal heart rate, ventilation maximal power output compared to the MICT protocol. Subgroup analysis determined that training period < 12 weeks, training frequency three times/week, 20 min per intervention, < 80% intensity VO 2 peak, 3 repetitions, < 60s per training session, and ≤ 90s rest time had the greatest effect on VO 2 max. Compared with MICT, HIIT was more effective in improving cardiorespiratory fitness and exercise capacity in older adults.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"115 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86793210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phrase “exercise is medicine” has continously been used to emphasize the physiological, pshychological and social benefits of exercise. This research aims at comparing the effect of blood genotype and exercise on some physiological parameters in fit and willing undergraduate students. Methods: 75 undergraduate students in the faculty of Basic Medical Science volunteered to participate in the study. A predesigned, pre-tested, self-administered questionnaire was filled by the students. Physiological variables such as heart rate, blood pressure and respiratory variables was then measured before exercise and at time intervals after the exercise testing on a calibrated motorist treadmill. Results: Blood genotype SS had the highest systolic blood pressure immediately after exercise (155.50 ± 6.91 mmHg) compared to blood genotype AS (155.40 ± 7.00 mmHg) and blood genotype AA (154.88 ± 8.70 mmHg) with significant difference (P < 0.05). Blood genotype AS had the highest systolic blood pressure 15 minutes after exercise (129.63 ± 9.79 mmHg) compared to blood genotype AA (129.13 ± 9.35 mmHg) and SS (122.13 ± 18.50 mmHg) with significant difference (P < 0.05). Blood genotype AS had the highest diastolic blood pressure immediately after exercise (95.29 ± 8.16 mmHg) compared to blood genotype AA (80.34 ± 11.46 mmHg) and SS (94.91 ± 11.81 mmHg) with significant difference (P < 0.05). Blood genotype AS had the highest diastolic blood pressure 15 minutes after exercise (85.60 ± 7.50 mmHg) compared to blood genotype AA (83.63 ± 9.18 mmHg) blood genotype SS (83.63 ± 9.18 mmHg) with significant difference (P < 0.05). Conclusion: Given the benefits of exercise, students should be encouraged to engage in light and moderate exercise irrespective of their blood genotype.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79676563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
