The impact of step reduction on muscle health and aging

Dr. Oi Kawa provides insights on the effects of step reduction and physical inactivity on muscle health and aging. Research shows that even short periods of reduced steps can lead to negative consequences, including impairments in glucose handling and increased inter-abdominal fat. This is significant because sarcopenia, the progressive loss of muscle mass with age, starts as early as the third decade of life. The rate of muscle mass loss is about 1 to 3% per year, which can be accelerated by periods of disuse. Resistance training has been shown to be an effective strategy in mitigating muscle loss during disuse. Protein supplementation can also help, especially with adequate protein intake spread evenly throughout the day.
