Interventions

This is a randomized, controlled, double-blind clinical study. Participants will be randomly assigned to three groups. The intervention group will consist of 22 participants who will undergo a blood f

the placebo group will consist of 22 participants who will perform the same blood flow restriction training protocol with the photobiomodulation device turned off

and the control group will consist of 22 participants who will perform a conventional resistance training protocol. The blood flow restriction training protocol will be performed on the dominant upper

however, the load will be 80% of 1RM and no sphygmomanometer will be used. The photobiomodulation protocol will be applied to the belly of the biceps brachii muscle for 90 seconds, delivering an energ

Design outcomes

Primary

Measure	Time frame
It is expected to find an improvement of at least 10% in the isometric peak torque of the biceps brachii, assessed using a handheld dynamometer. Data will be collected 48 hours before the beginning of the intervention and 48 hours after the last intervention	—

Secondary

Measure	Time frame
It is expected to find an improvement of at least 10% in the muscle size of the biceps brachii, assessed by musculoskeletal ultrasound. Data will be collected 48 hours before the beginning of the intervention and 48 hours after the last intervention;It is expected to find an improvement of at least 10% in the muscle strength of the biceps brachii, assessed by the one-repetition maximum test. Data will be collected 48 hours before the beginning of the intervention and 48 hours after the last intervention	—
