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.
