Interventions

This will be a clinical trial, in which 14 (fourteen) participants will undergo three experimental sessions at random. Participants will undergo an anamnesis, anthropometric analyzes to measure height
session 2: 1 series per exercise – low volume, and control session: no exercise. In sessions 1 and 2, 7 exercises will be performed for the major muscle groups (squats with hexagonal barbell
2 – Straight bench press with barbell
3 – Horizontal Leg Press
4- Pull-down with barbell
5 – Extension chair
6 – Development of shoulder on the machine
7 – Flexor chair), totaling 7 series in the low volume session and 21 series in the high volume session. The sessions will take place at the end of the afternoon, between 8:00 pm and 9:00 pm, and the
