Brisk walking improves motor function and lower limb muscle strength in Chinese women aged 80 years and older.
Study Goal
The researchers investigated the role of pantothenic acid (Vitamin B5) as one of the key metabolites involved in metabolic pathways affected by a 12-week brisk walking exercise program in elderly women.
Results Summary
Pantothenic acid was identified as one of fifteen significant differential metabolites linked to improved exercise capacity, alongside other amino acids and metabolites, suggesting its potential role in metabolic regulation during physical activity. The study did not isolate pantothenic acid's specific effects but noted its association with enhanced exercise-related outcomes.

This study investigates the effects of a 12-week brisk walking exercise regimen on motor function improvements in elderly women. Twenty-six elderly women, aged 84.2 ± 3.2 years, participated in a 12-week brisk walking exercise program. Fitness assessments and blood biomarker analyses (including CHO, HDLC, LDLC, TC) were conducted pre- and post-intervention. Additionally, targeted metabolomics was employed to measure short-chain fatty acids, amino acids, and vitamin metabolites. The intervention led to significant enhancements in participants' flexibility (p < 0.05), lower limb muscle strength (p < 0.01), and cardiorespiratory endurance (p < 0.01), while muscle mass showed no significant changes. Fifteen significant differential metabolites were identified (VIP > 1.0, FC > 1.2 or < 0.8, and p < 0.05), with arginine, ornithine, aspartic acid, glutamine, phenylalanine, tyrosine, and pantothenic acid playing key roles across seven metabolic pathways. A 12-week brisk walking exercise program significantly enhanced flexibility, lower limb muscle strength, and cardiorespiratory endurance among elderly women. These improvements did not extend to muscle mass or upper limb muscle strength. The observed enhancement in exercise capacity may be attributed to improved regulation of neurotransmitters.
