Key result
Heart rate variability indices differed significantly by sex (p<0.01 for frequency domain variables) but not between endurance-trained and power-trained elite track-and-field athletes.
Why the study?
Are there significant differences in heart rate variability indices between endurance-trained and power-trained elite track-and-field athletes?

Sex differences may warrant sex-specific HRV norms in elite athletes; leaves open training-modality effects on autonomic function.

Are there significant differences in heart rate variability indices between endurance-trained and power-trained elite track-and-field athletes?
p-value: p=<0.01
In elite track-and-field athletes, heart rate variability differs significantly by sex but does not differ between those with endurance versus power training emphasis.
Berkoff et al. (2007) conducted a cross-sectional in Elite track-and-field athletes (n=145). Endurance training vs. Power training was evaluated on Heart rate variability indices (p=<0.01). Heart rate variability indices differed significantly by sex (p<0.01 for frequency domain variables) but not between endurance-trained and power-trained elite track-and-field athletes.
