Changes in skeletal muscle mass (SMM) are not associated with improvements in walking speed.
Improvements in walking speed may not require increases in muscle mass, focusing instead on strength and quality.
StrongRefutesmedium confidence
The percentage change in 10-MWT was significantly associated with percentage change in MQI (r = -0.46, P = .04) and KE1RM (r = -0.45, P = .04), however not associated percentage of changes in SMM (r = 0.01, P = .97).
Why this rating
Based on the study design involving a controlled intervention with measurable outcomes.

More from this paper
- The improvement in the 10-meter walking test (10-MWT) after an 8-week resistance training program is associated with increases in lower limb muscular strength (KE1RM) by 8.6% and muscle quality index (MQI) by 7.2%.Strong
- Resistance training resulted in significant changes in body composition, including a decrease in fat mass by 1.4% and an increase in fat-free mass by 1.6%.Strong
