Summary

An 8-week intervention of the sit-to-stand test (STS) of 5 and 10 repetitions will be performed to two randomly selected groups to compare its effect on the muscle architecture of the vastus lateralis muscle. H1: 10 STS significantly modifies vastus lateralis muscle architecture in adults compared to 5STS and the control group.

Detailed description

Participants will be required to attend the laboratory for a first familiarization visit, where descriptive, biometric, and medical variables will also be evaluated. In addition, during this first familiarization session, it will be previously determined if the participants present any exclusion criteria and their muscle architecture will also be evaluated. After the familiarization session and the participants have signed the informed consent form, they will be randomly assigned to a 5 STS, 10 STS, or control group. Each group (exception of the control group) will be asked to perform three times a week one of the STS modalities assigned to them for 8 weeks, to ensure that the test is completed correctly and also to maintain the planning, the evaluator will be connected virtually with the participants, where rest times will be controlled and a fatigue perception scale will be performed at the end of each session, which will allow controlling the process each session. Subsequently, participants will be asked to attend the laboratory to re-evaluate their architectural parameters ( pennation angle, fascicle length, and muscle thickness) of the quadriceps muscle, one week after performing the intervention.

Interventions

Type	Name	Description
OTHER	Group 5 STS	For 8 weeks, 3 times per week and 3 sets of 5 repetitions during the first month, then 5 sets of 5 repetitions during the second month. Between each repetition, there will be a rest of 30 to 60 seconds approximately.
OTHER	Group 10 STS	For 8 weeks, 3 times per week and 3 sets of 10 repetitions during the first month, then 5 sets of 10 repetitions during the second month. Between each repetition, there will be a rest of 30 to 60 seconds approximately.
