Summary

This study tests whether shining a special light (photobiomodulation) on the thigh muscles before electrical stimulation can reduce fatigue, muscle damage, and soreness. 36 healthy adults will receive either real or fake light therapy, then undergo a series of electrical muscle contractions. Researchers will measure strength, muscle activity, and soreness over several days to see if the light helps.
