Design outcomes
Primary
| Measure | Time frame |
|---|---|
| At baseline (T0), after 5 weeks (T1), and after 10 weeks (T2), maximal strength in the back squat and bench press was assessed using a 10-repetition maximum (10RM) test. In addition, body composition was evaluated using bioelectrical impedance analysis (BIA), including measurements of body mass, fat-free mass, fat mass, and skeletal muscle mass. | — |
Secondary
| Measure | Time frame |
|---|---|
| Cognitive performance was assessed using the Eriksen Flanker Test and the Stroop Test. Assessments were conducted at baseline (T0), after 5 weeks of training (T1), and following completion of the 10-week intervention (T2). | — |
