Effects of Manual Massage and Foam Rolling on Heart Rate Variability Following 20m-Shuttle Run Test in Elite Male Handball Players
Effects of Manual Massage and Foam Rolling on Heart Rate Variability Following 20m-Shuttle Run Test in Elite Male Handball Players
This study aimed to compare the acute effects of manual massage (MM) and foam rolling (FR) on heart rate variability (HRV) following a 20 m shuttle run test (20m-SRT) in elite male handball players. It was hypothesized that MM and FR would produce differential acute effects on HRV responses during
The aim of present study was to compare the acute effects of manual massage (MM) and foam rolling (FR) on time-domain and frequency-domain HRV parameters following a 20 m shuttle run test (20m-SRT) in elite male handball players. It was hypothesized that MM and FR would produce differential acute effects on HRV responses during. Fifteen elite male handball players voluntarilly participated in present study.
The research utilized a randomized cross-over design. All participants provided written informed consent after being briefed about the aims, procedures, benefits, and risks. Study was conducted in three sessions in onwe week. Fırst session is familiarization, other two sessions are experimental: MM and FR sessions. Participants were instructed to maintain their normal diet, refrain from intense exercise for at least 48 hours before study sessions, avoid alcohol and caffeine intake for 24 hours prior, and consume their last meal at least 3 hours before sessions. In familiarization session, subjects fulfilled Exercise Readiness Questionnaire (EGZ+), measured body composition, after warm-up 20m-SRT, and recovery interventions (MM and FR). Before warm-up - pre-test, during 20-m shuttle run test - test and after recovery - post-test HRV were recorded. In experimental session, after the 20 min standard warm-up including jogging, jumping and stretching volunteers performed 20m-SRT and immediately one of two different recovery interventions. Recovery interventions are MM and FR applied on the lower extremities. All procedures were conducted at the same time of day (14:00-16:00) to minimize circadian rhythm effects. To determine differences in HRV and heart rate across recovery methods and time points, a Two Way Repeated Measures ANOVA was used: 2 Intervention (MM and FR) × 3 Time (Pre-test, Test, Post-test). Bonferroni-adjusted pairwise comparisons performed to identify differences between specific time points and interventions.
