Enrollment: 136
Sex: ALL
Minimum age (years): 18
Maximum age (years): 30
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: TREATMENT

Brief summary: A total of 154 healthy young individuals will be recruited by purposive sampling method to participate in a randomized, single-blinded, sham-controlled study. Recruited participants will be randomly dividing into two groups, the Active high-intensity laser therapy (a-HILT) group, and the Sham high-intensity laser therapy (s-HILT) group. The treatment duration will be 10 minutes per session on both lower limbs for each day for 3 days/week for 2 weeks. Hamstring muscle length will be assessed at baseline, end of the 2-week post-intervention period.
