The Effectiveness of Squat Exercise for Improving Pre-Sarcopenia in Order Adults

Tzu Chi University80 enrolled

Overview

With the growing aging population, it has been reported that approximately 10-20% of older adults have pre-sarcopenia. Pre-sarcopenia is defined as a decline in either muscle mass or muscle strength. Previous studies have indicated that squat exercise has significant effects on improving lower-extremity muscle strength and physical performance. Early intervention through resistance exercise during the pre-sarcopenia stage may increase muscle mass, enhance physical performance, and prevent progression to sarcopenia. Therefore, the purpose of this study is to investigate the effects of squat exercise on improving pre-sarcopenia among older adults. It is expected that, following the squat exercise intervention, older adults will demonstrate significant improvements in muscle mass, lower-extremity muscle strength, physical performance, and body composition, thereby alleviating pre-sarcopenia.

Able to read, have clear consciousness, and communicate in Mandarin. 4. Willing to participate in this study. Exclusion Criteria: 1. Individuals with disability. 2.

Outcomes

Primary Outcomes

Physical performance assessed by the Short Physical Performance Battery (SPPB)

Physical performance will be assessed using the Short Physical Performance Battery (SPPB). The SPPB consists of three components: balance test, gait speed test, and chair stand test. Total scores range from 0 to 12 points, with higher scores indicating better physical performance

Time frame: Baseline, 6 weeks, and 12 weeks

Body composition assessed by bioelectrical impedance analysis (InBody)

Body composition will be assessed using bioelectrical impedance analysis (InBody).Measurements include skeletal muscle mass, body fat mass, and body fat percentage.
