Summary: Objectives: This study aimed to investigate the impact of training one arm with a high load on the muscle size and strength of the opposing arm training with a low load. The results showed that high load training on one arm led to changes in strength of the opposing arm, but only the directly trained arms showed changes in muscle thickness.

Summary: This study systematically reviewed the effects of power training versus strength training in older adults. The results showed that power training is more effective in improving muscle power and performance on activity tests compared to strength training. Future research should focus on evaluating exercise parameters for power training in older adults and establishing a standardized test protocol that includes measurements of physical activity in daily life.

Summary: The study found that both low-speed and high-speed resistance training can reverse frailty status and improve physical performance in elderly individuals. While both types of training improved muscle strength and power, they showed different patterns of improvement, with low-speed resistance training being more effective in reversing frailty status.

Summary: We compared the changes in strength and muscle mass between stronger and weaker older women in response to resistance training. The study found that both groups showed similar gains in muscle mass and upper-limb strength, but weaker women experienced greater improvements in lower-limb strength. This suggests that older women, regardless of their initial strength levels, can benefit from resistance training for muscle and strength gains.

Summary: The aim of this study was to evaluate the effect of exercise interventions on glycaemic control in children and adolescents with type 1 diabetes mellitus (T1DM) and to examine the characteristics of the interventions. The study found that exercise interventions longer than 24 weeks, with at least 60 minutes of high-intensity exercise per session, may serve as a supportive therapy for metabolic control in youth with T1DM.

Summary: This study conducted a meta-analysis to examine the association between glycated hemoglobin and physical activity, sedentary behavior, and physical fitness in children and adolescents with type 1 diabetes. The findings suggest that low levels of physical activity and cardiorespiratory fitness, as well as extensive sedentary behavior, may contribute to poor glycemic control in youth with type 1 diabetes.

Summary: The aim of this study was to investigate the association between adherence to the 24-h movement guidelines during adolescence and glucose outcomes and type 2 diabetes mellitus (T2DM) in adulthood. The results showed that adolescents who met physical activity and screen time guidelines had a lower risk of T2DM in adulthood, and those who met all three guidelines had the lowest risk.

Summary: Understanding the impact of COVID-19 on muscle strength can provide insights into the organs involved in acute and chronic COVID-19 sequelae. This study investigated the muscle strength of long-COVID-19 patients compared to a control group, and found that grip strength and leg extension strength were significantly lower in COVID-19 survivors. The relationship between long-COVID syndrome and muscle strength was partly mediated by the lower appendicular lean mass index (ALMI).

Summary: Exercise intolerance remains a major unmet medical need in patients with heart failure, and skeletal myopathy is considered as the major limiting factor. Recent studies have suggested that circulating myokines synthesized and secreted by skeletal muscle may provide new insights into the pathophysiology and classification of HF-related skeletal myopathy. These myokines may also serve as biomarkers to personalize physical training for patients with HF and exercise intolerance. Furthermore, the production and secretion of myokines in patients with HF may interact with systemic alterations and affect cardiac structure and function, which can influence adverse cardiac remodeling and clinical outcomes in HF patients.

Summary: The aim of this study was to determine whether Colombian preschool-aged children meet all three 24-hour movement guidelines and to explore the associations between socio-ecological correlates and meeting these guidelines. A cross-sectional study was conducted with data from the National Survey of Nutritional Situation (ENSIN-2015) in Colombia, 2015-2016. The sample consisted of 3002 low-income preschoolers (3-4 years old, 50.7% boys). Data on physical activity, screen time, and sleep time were collected using a questionnaire reported by parents. The prevalence of preschoolers meeting all three 24-hour movement guidelines was 4.8%, and the prevalence of not meeting any of the guidelines was 16.6%. Boys and children without a television in their bedroom were more likely to meet all three movement guidelines. Strategies to promote adherence to these guidelines in low-income preschoolers should consider the importance of sex and home environment changes.

Summary: Exercise and physical activity have significant benefits for older adults with various physical and neuropsychological diseases and disabilities, including those without pharmacological treatments or with risky treatments. However, exercise is underutilized and not fully integrated into geriatric medicine practice. Frailty should not be seen as a barrier to exercise, but rather a reason to prescribe it. Exercise prescription needs to be emphasized in the training of healthcare professionals and seen as a mandatory component in geriatric medicine.

Summary: This study aims to evaluate the impact of a 12-week gamified family-based health and exercise intervention on physical fitness, basic motor competencies, mental and behavioral health, and adherence to 24-h movement guidelines in children aged 4 to 5 years old. The study will assess changes in sedentary levels, physical fitness, basic motor competencies, mental and behavioral disorders, adherence to the exercise program, and compliance with physical activity recommendations. The exercise group will undergo a 12-week exercise intervention, while the routine care group will receive routine care for 12 weeks followed by a control period.

Summary: This study aimed to understand the cardiometabolic factors in hip and knee osteoarthritis (OAD) and their association with different body composition phenotypes characterized by muscle mass and adiposity. The study found that OAD is associated with hypertension and increased cardiovascular risk in older adults. The low muscle mass/high adiposity phenotype is particularly related to cardiometabolic factors.
