Comparison between hip resistance training and ankle resistance training on functional mobility in older adults: a 6-week intervention study
摘要
Globally, one in three adults over 65 years experiences a fall each year, resulting in 37 million severe fall injuries annually, making falls a leading cause of disability and reduced quality of life. Despite evidence of hip and ankle strategies in postural control, few studies directly compare their role in functional mobility.
Aim/ObjectiveThis study aimed to compare the effectiveness of hip resistance training and ankle resistance training in improving muscle strength, balance, and quality of life among older adults.
MethodologyA pretest–posttest experimental design was employed, involving 30 participants aged 65–80 years, randomly allocated into two groups. Group A performed resistance exercises targeting ankle dorsiflexors and plantar flexors, while Group B focused on hip flexors and extensors. Both groups followed a 6-week intervention program with three sessions per week. Outcome measures, including muscle strength, balance, and quality of life, were assessed at baseline and post-intervention.
ResultsSignificant improvements in muscle strength (p < 0.01) and balance (p < 0.05) were observed in both groups, with Group A showing greater improvements in ankle strength and balance (p < 0.01) compared to Group B. However, Quality-of-life improvements did not differ significantly between groups (p = 0.369), possibly due to the short intervention duration and the subjective nature of QoL assessments.
ConclusionAnkle resistance training proved more effective than hip-focused training in enhancing muscle strength and balance in older adults. These findings underscore the importance of ankle-specific exercises in fall prevention and mobility enhancement strategies for the elderly population.
