Objective: To find and compare the clinical and psychological effects of low and high-intensity aerobic training combined with resistance training in community-dwelling older men with post-COVID-19 sarcopenia symptoms.
Design: Randomized control trial.
Setting: University physiotherapy clinic.
Participants: Men in the age range of 60-80 years with post-COVID-19 Sarcopenia.
Intervention: All participants received resistance training for whatever time of the day that they received it, and that in addition they were randomized into two groups like low-intensity aerobic training group ( = 38) and high-intensity aerobic training group ( = 38) for 30 minutes/session, 1 session/day, 4 days/week for 8 weeks.
Outcomes: Clinical (muscle strength and muscle mass) and psychological (kinesiophobia and quality of life scales) measures were measured at the baseline, fourth week, the eighth week, and at six months follow-up.
Results: The 2 × 4 group by time repeated measures MANOVA with corrected post-hoc tests for six dependent variables shows a significant difference between the groups ( < 0.001). At the end of six months follow up, the handgrip strength, -3.9 (95% CI -4.26 to -3.53), kinesiophobia level 4.7 (95% CI 4.24 to 5.15), and quality of life -10.4 (95% CI -10.81 to -9.9) shows more improvement ( < 0.001) in low-intensity aerobic training group than high-intensity aerobic training group, but in muscle mass both groups did not show any significant difference ( > 0.05).
Conclusion: Low-intensity aerobic training exercises are more effective in improving the clinical (muscle strength) and psychological (kinesiophobia and quality of life) measures than high-intensity aerobic training in post-COVID 19 Sarcopenia.

The scope of this article is to analyze the temporal trend and macro-regional distribution of the options on offer in terms of collective activities of bodily practices and physical activities (BPPA) and the number of participants in primary health care, developed by all health professionals and by Physical Education Professionals in Brazil. It involved an ecological time-series study, using data from the Health Information System for Primary Health Care (Sisab) between 2014 and 2022, which was assessed using regression analysis and Joinpoint software. At the national level, the results revealed an increase in the number of collective BPPA activities and participants in primary health care developed by all health professionals and by Physical Education Professionals between 2014 and 2019, followed by a reduction in both in 2020.

The purpose of this study was to determine the effective warm-up protocol using an added respiratory dead space (ARDS) 1200 ml volume mask to determine hypercapnic conditions, on the swimming velocity of the 50 m time trial front crawl. Eight male members of the university swimming team, aged 19-25, performed three different warm-up protocols: 1) standardized warm-up in water (WUCON); 2) hypercapnic warm-up in water (WUARDS); 3) hypercapnic a 20-minute transition phase on land, between warm-up in water and swimming test (RE-WUARDS). The three warm-up protocols were implemented in random order every 7th day.

Background: Health behaviors, health, and income change during aging. However, no previous studies have examined, how they develop together over the transition to statutory retirement. We aimed to examine their joint development and to identify the determinants of any distinct trajectories.

Background: Falls on stairs are a major cause of severe injuries among older adults, with stair descent posing significantly greater risks than ascent. Variations in stair descent phenotypes may reflect differences in physical function and biomechanical stability, and their identification may prevent falls.
Aims: This study aims to classify stair descent phenotypes in older adults and investigate the biomechanical and physical functional differences between these phenotypes using hierarchical cluster analysis.
Quantification of training-induced alterations in body composition via automated machine learning analysis of MRI images in the thigh region: A pilot study in young females.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.
