Key result
A competitive rugby game significantly reduced parasympathetic modulation and the supine to standing change in HRV (LF/HF ratio -1.0 vs -3.0) for up to 4 days post-game (p<0.05).
Why the study?
Does a training week including a competitive game alter heart rate variability in elite youth rugby league players?
Population
9 elite youth rugby league players, age 17-20 years
Comparison
Weekly training including a competitive game vs Within-subject comparison across different days

Post-game HRV suppression indicates prolonged autonomic recovery in youth rugby players; hypothesis-generating for daily monitoring, should not yet change practice.

Does a training week including a competitive game alter heart rate variability in elite youth rugby league players?
Absolute Event Rate: -1% vs -3%
p-value: p=<0.05
Monitoring day-to-day fluctuations in heart rate variability may provide a useful tool for tracking player workload and autonomic recovery in elite youth rugby players.
Edmonds et al. (2013) conducted an observational in Elite youth rugby league players (n=9). Weekly training including a competitive game vs. Pre-game baseline was evaluated on Supine to standing change in HRV (LF/HF ratio) (p=<0.05). A competitive rugby game significantly reduced parasympathetic modulation and the supine to standing change in HRV (LF/HF ratio -1.0 vs -3.0) for up to 4 days post-game (p<0.05).
