- * Participants were assessed using various tests to categorize them based on LS, and daily PA was measured with wrist accelerometers.
- * Findings revealed that women engaging in more than 28 minutes of moderate to vigorous physical activity daily had significantly lower odds of LS compared to those who were less active, while this association was not found in men, highlighting potential sex differences in the relationship between PA and LS.
Article Synopsis
- The study investigates site-specific muscle loss in elderly males (ages 65-74) with locomotive syndrome (LS), a condition characterized by reduced mobility.
- Researchers compared 100 men using risk tests for LS and found that those with LS had lower muscle mass, particularly in the rectus abdominis and anterior thigh, and exhibited poorer physical performance in tests like sit-ups and walking times.
- The findings suggest that specific muscle loss may be linked to age-related physical functions, highlighting the impact of LS on mobility and muscle health in older adults.
Article Synopsis
- Older adults with subjective cognitive decline often experience poor gait performance, leading to higher risks of falls and decreased activity levels.
- This study aimed to compare the short- and long-term effects of aerobic training, resistance training, and combined training on gait performance in older adults.
- Results showed that all exercise interventions improved gait performance shortly after the program, but resistance training was most effective for long-term improvements in specific gait parameters after six months.
Article Synopsis
- * Involving 678 participants, it compared the CS-30 results with established sarcopenia criteria and other muscle strength tests, using ROC analysis to determine optimal CS-30 scores for diagnosing the condition.
- * Findings revealed a positive correlation between CS-30 scores and sarcopenia, identifying 15 stands for women and 17 for men as optimal cut-off points for screening.
Objectives: Physical activity is associated with improvement in overall health and well-being, but robust evidence with comprehensive assessment of general health is lacking. This study aimed to clarify the effects of physical activity on intrinsic capacity among community-dwelling older adults with subjective memory concerns.
Design: A single-blind randomized controlled trial compared aerobic training (AT), resistance training (RT), and combined training (AT+RT) programs for improving general health evaluated by intrinsic capacity.
Background: Physical exercise has been linked to reduced frailty, but there is insufficient evidence of beneficial effects in community-dwelling older adults with subjective cognitive concerns.
Objective: This study aimed to clarify the effects of physical exercise in this population.
Design: Single-blind randomised controlled trial.
The purpose of the present study was to investigate the effect of the progressive walking program on lower limb muscle size and strength and evaluated whether the stair-climbing exercise provided additional training effects when combined with the walking program. Fifteen elderly subjects (age 69 ± 1 years, height 1.63 ± 0.

Methods: We included 223 middle-aged and elderly individuals in this study (104 men and 119 women; age: 40-85 years).
Article Synopsis
- - The study investigated the impact of a 17-week progressive walking program on reducing the risk of locomotive syndrome in 24 untrained elderly Japanese individuals, averaging 68 years old.
- - Participants underwent various tests to measure their locomotive function and muscle strength at the beginning, midway, and end of the program.
- - Results showed significant improvements in both the two-step test and geriatric locomotive function scale scores, linked to increased knee flexor strength and better overall physical function.
Influence of muscle fibre composition on muscle oxygenation during maximal running.
BMJ Open Sport Exerc Med
November 2015
Aims: To investigate the relationship between muscle oxygenation (specifically, the levels of oxygenated haemoglobin and myoglobin [oxyHb/Mb]) during maximal running and muscle fibre composition, and to determine whether muscle fibre composition can be non-invasively estimated from oxyHb/Mb levels during maximal running.
Methods: Eight male runners ([Formula: see text], 60.9± 4.
Aim: Here, we aimed to compare the effect of a combination of body mass-based resistance exercise and moderate-intensity (55% peak oxygen uptake [ V˙O peak]) walking or high-intensity (75% V˙O peak) walking on muscle size and V˙O peak in untrained older women.
Methods: A total of 12 untrained older women (mean age 60 ± 2 years) were randomly assigned to either a moderate-intensity aerobic training group (n = 6) or high-intensity aerobic training group (n = 6). Both groups carried out body-mass based (lower body) resistance exercises (2 sets of 10 repetitions) on 3 days/week for 8 weeks.
