Interventions/Control_1
Comparison with Standardized Exercise Intensity
Participants were divided into two groups: the CFT group and the circuit training group. The CFT group performed two sets of "Squats 10 reps, Burpee Jumps 10 reps, Sit-ups 10 reps, Push-ups 10 reps" with no rest between exercises. The CT group performed two sets of the same training with 15 seconds of rest between exercises.
Interventions/Control_2
Comparison with Standardized Exercise Duration
Participants were divided into two groups: the CFT group and the circuit training (CT) group. The CFT group performed "Squats: 10 reps, Burpee jumps: 10 reps, Sit-ups: 10 reps, Push-ups: 10 reps" for 4 minutes without rest between exercises. The CT group performed the same training with 15 seconds of rest between exercises for 4 minutes.
