This research examined the impact of combining LM extract supplementation with resistance training on muscle hypertrophy in older adults. Methods:  This randomized controlled trial allocated fourteen older adults (65-79 years) to either an LM supplement group (n=7) or a placebo group (n=7). Participants engaged in low-load resistance training twice weekly for 12 weeks while receiving their designated supplements. Muscle thickness at the anterior thigh (AT) was assessed using B-mode ultrasound at baseline, 6 weeks, and 12 weeks to evaluate muscle hypertrophy. Trial registration: UMIN000050432. Results:.A 12-week intervention yielded significant muscle thickness enhancements in both groups. Nonetheless, the LM group exhibited a substantially greater relative increase (p < 0.05) compared to the placebo group. Furthermore, the low-load resistance training program elicited a significant 7.4% increase in muscle thickness in the LM group at six weeks, whereas the placebo group displayed a negligible 0.1% change. Conclusions: The present study suggests that intake of LM extract could enhance the muscle hypertrophy effect of resistance training and requires further investigation in the future.
