Participants were divided into active and inactive groups based on weekly LPA and moderate-to-vigorous intensity physical activity (MVPA). Cox proportional hazards regression model was used to calculate hazard ratio (HR) and 95% confidence interval (CI), according to disability status and physical activity levels.RESULTS: During 3.3±0.4 years follow-up period, 1,024 deaths occurred from all causes. Among non-disabled people, the inactive group showed a significantly higher risk of all-cause mortality (HR=1.282, 95% CI=1.122–1.465, p<.001) than the active group (reference= 1) in LPA. Similarly, for MVPA, the risk of all-cause mortality was significantly higher in the inactive group (HR=1.522, 95% CI=1.230–1.882, p<.001) than in the active group (reference=1). However, among physically disabled people, the inactive group correspondingly showed a significantly higher risk of all-cause mortality (HR=2.735, 95% CI=1.761–4.246, p<.001) than the active group, while there was no significant difference between both groups in MVPA.CONCLUSIONS: The current findings suggest that promoting LPA may play an important role in preventing premature death from allcause mortality in older adults with physical disability.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48257396","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}

This systematic review evaluated the effectiveness of aquatic training for children from the perspective of body composition.METHODS: A meta-analysis was performed to determine the potential impact of aquatic training in children. Four databases, namely Scopus, PubMed, Web of Science, and EBSCO, were used for the systematic search from September 2010 to November 2021. The mean differences in the data were analyzed using Stata 15.1 software with a 95% confidence interval. Outcome measures included weight, body mass index (BMI), fat percentage (Fat%), and waist circumference.RESULTS: Eleven studies, comprising eight randomized controlled trials (RCT) and three non-RCT studies, evaluating the effect of aquatic training on children were analyzed and reported. Aquatic training significantly improved the BMI (p<.01) and Fat% (p<.01) in children (ES (95% CI)=-0.23 (-0.38, -0.08) and ES (95% CI)=-0.27 (-0.45, -0.08).

The participants were divided into two groups: mat Pilates exercise group (MP, n=10) and non-Pilates control group (CON, n=10). The MP group participated in the mat Pilates exercise program for 60 minutes a day, 3 days per week for 8 weeks. Back pain and basal physical fitness were assessed before and after the experimental period. Left and right core stabilities at 0°, 45°, 90°, 135°, and 180° were measured using Centaur (BFMC, Germany). Isokinetic muscle function (60°/s) of both the knee and trunk was also measured using the isokinetic dynamometer Cybex.RESULTS: After mat Pilates exercise for 8 weeks, there was a significant interaction between the MP and CON groups in back pain during daily activity and lower back stiffness (p<.05), respectively. There was also a significant interaction between the two groups in the left and right core stability at 45°, 90°, 135°, and 180° (p<.05, p<.01, p<.001), respectively. Additionally, there was a significant interaction between the two groups in the right knee and left knee isokinetic extensor muscle strength (p<.05, p<.001, respectively). However, there was no significant interaction between the two groups in trunk isokinetic extensor and flexor muscle strength (NS). There were no significant interactions between two groups in the muscle mass of total body, trunk, and legs (NS), respectively. Regarding basic physical fitness, there were significant interaction effects between the two groups in cardiovascular fitness, sagittal reach, and sit-ups (p<.05).CONCLUSIONS: These results suggest that continued mat Pilates exercise can improve back pain and core stability with enhancement of leg isokinetic muscle strength independent of the muscle mass of the total body, trunk, and legs.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44653843","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}

Before the training program, the participant took part in a 1,500-m track and field national event in April and the onset of blood lactate threshold was analyzed using (OBVA/ vOBLA), VO2max/vVO2max, and tVO2max tests. After completing the 4-week training program, the participant again took part in the 1,500-m track and field national event in May and her parameters were reassessed using the OBVA/vOBLA, VO2max/vVO2max, and tVO2max tests.RESULTS: Pre- and post-training indicate that vVO2max did not improve; however, tVO2max (206 seconds pre-training vs. 251.51 seconds post-training) and VO2max (56.4 vs. 59.3 VO2 mL/kg/min)significantly. However, this improvement in relative VO2 was due to weight loss, and the absolute value of VO2 (3.63 vs. 3.62 L/min) did not change. The 1,500-m race record in track and field events decreased significantly from a pre-training value of 5 minutes 03 seconds to a post-training value of 4 minutes 52 seconds.

However, volumetric muscle loss (VML) injury, a large volume of muscle loss beyond the self-repair capacity, causes functional disability and morphological deformities. This study investigated the effects of myofiber injection into a decellularized extracellular matrix (ECM) and resistance training (RT) on skeletal muscle regeneration following VML injury.METHODS: 6-months-old male Fischer CDF rats and 2-months-old F344-Tg (UBC-EGFP) rats (myofiber donors) were used in this study. Approximately 20% of the mass of the lateral gastrocnemius (LGAS) was excised and replaced by ECM of similar dimensions. Thirty myofibers were injected into the injured region seven days post-injury. Ladder climbing (RT) was allowed 10 days post-defect surgery, and the rats were subjected to ladder climbing with a weight every third day for 6 weeks.RESULTS: After 56 days of recovery and exercise training, the cross-sectional area (CSA) of intact muscle in the EXE group (5,104±92 μm2) increased significantly compared to that in the ECM (4,657±79 μm2) group. The number of blood vessels larger than 20 μm in diameter, capillaries excluded, showed a significant difference between the ECM+EXE (34.25±4.2) and ECM (21.75±3.89) groups. A significant reduction of fibrosis in the ECM+EXE (44.50±1.6%) group was observed compared to the ECM (69.25±1.9%) and ECM+FIB+EXE (63.00±1.7%) groups. Moreover, the small muscle fiber area within the transplanted ECM was significantly larger in the ECM+EXE (1.37±0.03 mm2) than in both the ECM (0.49±0.01 mm2) and ECM+FIB (0.62±0.01 mm2) groups.CONCLUSIONS: These data suggest that ECM transplantation with RT effectively repairs VML by enhancing hypertrophy, angiogenesis, and myofiber infiltration throughout the entire ECM.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46959796","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}

This review assessed the considerable attention paid to biomaterials in healing damaged skeletal muscle.METHODS: A comprehensive search in PubMed, Web of Science, Google Scholar, and Wiley Online Library was conducted to obtain previous studies exploring the state of biocompatible tissue scaffolds for VML recovery.RESULTS: By regenerating the function of damaged skeletal muscle, tissue-engineered skeletal muscle construction could revolutionize the treatment of VML. However, transporting cells into the wounded muscle location presents a significant challenge because it may result in unfavorable immunological reactions. The development and validation of several biomaterials with varying physical and chemical natures to treat various muscle injuries have recently been undertaken to overcome this problem. This review discusses the relative benefits of satellite cells (SC), the most prevalent skeletal muscle stem cells employed to seed scaffolds.CONCLUSIONS: Biomaterials can be used with skeletal muscle stem cells and growth factors to repair VML because of their customizable and desirable physicochemical qualities. Owing to the capacity of SCs for self-renewal and their undifferentiated state, these cells are excellent candidates for cell therapy. A large gap exists between understanding SC behavior and how it can be used to repair and regenerate human skeletal muscle tissue. Thus, this review sought to portray the current knowledge on the lifespan of SCs and their involvement in exercise-induced muscle regeneration and hypertrophy.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41789588","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}

Participants were categorized into three groups (‘Inactive’, ‘Active’, ‘Highly active’) according to physical activity guidelines. A chi-square test was performed to confirm whether the physical activity guidelines were met according to metabolic syndrome and the difference between metabolic syndrome according to age group. Logistic regression was used to predict the relationship between physical activity and metabolic syndrome.RESULTS: The prevalence of metabolic syndrome differed according to whether physical activity guidelines were met in older adults, and the prevalence of metabolic syndrome and its risk factors varied according to age group. Compared to the Inactive group, the odds ratios (OR) for metabolic syndrome were 0.73 (95% confidence interval [CI]: 0.56-0.95) and 0.65 (95% CI: 0.47-0.88) in adults in the Active and Highly active groups, respectively; and 0.46 (95% CI: 0.28-0.78) and 0.39 (95% CI: 0.22-0.69) in older adults in the Active and Highly active groups, respectively.CONCLUSIONS: As the level of physical activity increased, the OR of having metabolic syndrome and its risk factors decreased: this relationship was stronger in older adults than in adults.
