Inclusion criteria
Male or female adults aged 18-30 years. Apparently healthy, with no medical conditions that contraindicate participation in resistance training. A minimum of 6 consecutive months of resistance training experience. Regular resistance training participation of at least three sessions per week during the previous 6 months. Previous experience performing the back squat and bench press exercises with correct technique. Ability to perform maximal intended concentric velocity during resistance exercises. Willingness to refrain from vigorous physical activity during the 24 hours preceding each testing and training session. Ability and willingness to comply with all study procedures. Provision of written informed consent.
Exclusion criteria
Current musculoskeletal injury affecting the upper or lower limbs that limits participation in resistance training or testing. Acute or chronic pain that is aggravated by the study exercises. Cardiovascular, neurological, metabolic, or other medical conditions that contraindicate vigorous physical exercise. Current participation in another structured intervention study or clinical trial. Inability to attend the scheduled assessments or training sessions. Failure to comply with the study protocol or training requirements. Withdrawal of informed consent at any stage of the study. Occurrence of an adverse event during the intervention that prevents continued participation.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Acute resistance-training performance: total number of repetitions | First intervention session (Week 1), across the four training sets. | Total number of repetitions completed across four sets of bench press and back squat during the first intervention session. Participants will perform each set to momentary muscular failure at maximal intended concentric velocity, using individualized absolute loads corresponding to 75% of the estimated one-repetition maximum (1RM) for the bench press and 80% of the estimated 1RM for the back squat. Repetitions completed in each set and total repetitions per exercise will be recorded to compare the immediate effects of agonist stretching, antagonist stretching, and no stretching. |
