Brief summary

The present study aimed to evaluate the effects of foam rolling (FR) on recovery by examining selected time-domain and frequency-domain heart rate variability (HRV) parameters in elite swimmers following intensive interval sprint training. It was hypothesized that FR would enhance HRV recovery compared to active recovery performed through swimming.

Interventions

OTHERSwimming+FoamRollingRecovery

warm-up: 5 min FR, 5 min stretching, 1500 m low-tempo freestyle swim (\~20 min). PreT: HR and HRV baseline measurements. 1T: 50 m swim at 90-100% intensity; HRV, recorded. 2T: 3 × 50 m swim at 90-100% intensity with passive rest (\~15 s) between repetitions; HR recorded. Recovery Protocols: FR: 750 m Low Initensity Freestyle Swimming (\~10 min) + 10 min FR. PostT: HRV was recorded.
