Effects of a 12-Week Pilates Program on Functional Physical Fitness and Basal Metabolic Rate in Community-Dwelling Middle-Aged Women: A Quasi-Experimental Study.

Background: The aging society worldwide carries public and inevitable issues. Aging is accompanied by multiple diseases, and the health impacts challenge healthcare and social systems. In addition to medical treatment, exercise has been recognized as an effective strategy not only for disease prevention and alleviation, but also for multiple health benefits on health promotion. The purpose of this study was to investigate the effects of a suitable Pilates exercise intervention program on health maintenance and benefits in community-dwelling middle-aged women with a quasi-experimental design. Methods: We recruited healthy middle-aged community-dwelling women who had not regularly exercised in the previous three months. The participants were assigned to the experimental (n = 22) and control (n = 23) groups based on a quasi-experimental design. The experimental group participated in a mat-based Pilates exercise class twice a week (1 h/session) throughout the 12-week intervention, whereas there was no intervention for the control group. Body composition, basal metabolic rate, and functional physical fitness­comprising cardiovascular capacity, flexibility, muscular strength of upper limbs, muscular strength of lower limbs, core strength, agility, static balance, and dynamic balance­were assessed as primary outcomes in both groups before and after the intervention. Results: There were no significant differences in any of the dependent variables between the two groups before the exercise intervention. After the 12-week intervention, body composition, including body mass index, body fat (−1.5 to 3%), and basal metabolic rate (+10.6%), and functional fitness, including flexibility (+3.5%), core strength (+31.5%), lower-limb strength (+13.5%), agility (+7.3%), and balance (+4.2%), improved significantly in the experimental group relative to the control group (p < 0.05). Moreover, the improvement in physical fitness in lower-limb strength, agility, and balance for fall prevention also demonstrated higher clinical significance than the control. Conclusions: This 12-week mat-based Pilates exercise program significantly improved body composition, basal metabolic rate, and functional physical fitness in community-dwelling middle-aged women. The beneficial effects of Pilates exercise programs may thus promote improved health in the middle-aged female population, with practical implications for communities.

Isotonic and Isometric Exercise Interventions Improve the Hamstring Muscles' Strength and Flexibility: A Narrative Review.

BACKGROUND: Hamstring weakness has been associated with an increased risk of hamstring strain, a common sports injury that occurs when athletes perform actions such as quick sprints. The hamstring complex comprises three distinct muscles: the long and short heads of the bicep femoris, the semimembranosus, and the semitendinosus. METHODS: The researchers collected the data from different electronic databases: PubMed, Google Scholar, and the Web of Science. RESULTS: Many studies have been conducted on the numerous benefits of hamstring strength, in terms of athletic performance and injury prevention. Isotonic and isometric exercises are commonly used to improve hamstring strength, with each exercise type having a unique effect on the hamstring muscles. Isotonic exercise improves the muscles' strength, increasing their ability to resist any force, while isometric training increases strength and the muscles' ability to produce power by changing the muscle length. CONCLUSIONS: These exercises, when performed at low intensity, but with high repetition, can be used by the healthy general population to prepare for training and daily exercise. This can improve hamstring muscle strength and flexibility, leading to enhanced performance and reduced injury risk.

Novel Mat Exergaming to Improve the Physical Performance, Cognitive Function, and Dual-Task Walking and Decrease the Fall Risk of Community-Dwelling Older Adults.

Physical exercise and cognitive training were previously demonstrated to improve the physical functioning and decrease the incidence of falls for older adults. This study aimed to utilize an interactive exergame mat system to develop a novel cognitive-physical training program and explore the training effects on physical performance, cognitive function, dual-task walking (DTW), and fall risk compared to the control condition. In this quasi-experimental non-randomized controlled intervention study, 110 community-dwelling older adults participated. The exercise group (n = 56; mean age, 70.7 ± 4.6 years) performed ladder-type, three-by-three grid-type, and circle-type mat exergames with simultaneous cognitive-physical training (EMAT), while the control group (n = 54; mean age, 72.0 ± 5.7 years) underwent a multicomponent exercise intervention focused on physical and cognitive training. A 2 h training session was completed weekly for 3 months. Functional fitness (including upper- and lower-extremity strength and flexibility, grasp strength, aerobic endurance, static balance, dynamic balance and agility), a foot tapping test (FTT), the Montreal Cognitive Assessment (MoCA), DTW, and a fall risk questionnaire (FRQ) were assessed before and after the interventions. The EMAT program enhanced upper-extremity strength, lower-extremity strength and flexibility, aerobic endurance, and dynamic balance and agility; improved DTW and FTT performances; and decreased FRQ score. EMAT also showed a significant advantage over control in terms of lower-extremity strength and flexibility, aerobic endurance, dynamic balance and agility, and FRQ score (all P < 0.05). The current study provides evidence of the effects of a novel mat exergaming program on physical and cognitive performance. EMAT effectively reduced the fall risk and increased the dual-task ability of walking, factors that are important in fall prevention for community-dwelling older adults.
