Arms/Interventions Module

Arm Groups

Label	Type	Description	Intervention Names
Swimm + Foam rolling (FR)	Experimental	Warm-up: 5 min of foam rolling (FR), 5 min of stretching, and 1500 m of low-tempo freestyle swimming (~20 min). Pre-test: Baseline HR and HRV measurements were recorded. A 50 m swim was performed at 90-100% intensity. HR and HRV were recorded (T1). Participants completed 3 × 50 m swims at 90-100% intensity with passive recovery (~15 s) between repetitions. HR and HRV were recorded (T2). Recovery Protocol (FR): 750 m of low-intensity freestyle swimming (~10 min) followed by 10 min of FR. Post-test: HR and HRV were recorded.	Other: Swimming+FoamRollingRecovery
