Introduction: Previous research on competitive volleyball athletes has aimed to quantify jump loads; however, research is limited regarding cardiovascular stress in high-level volleyball. The purpose of this case study was to assess heart rate intensities and jump loads throughout a division I volleyball preseason.
Methods: Three, division I volleyball players (18-22 years old) were monitored throughout a full preseason period consisting of 15 practices including a competitive preseason scrimmage. Heart rate intensities and time spent in five different heart rate zones were measured using chest-worn heart rate monitors. Athletes were also equipped with a wearable microsensor device to quantify jump loads.
Results: There were main effects of practice sessions on high intensity jumps, maximum heart rate (HRmax), HRzone3 and HRzone4 (p ≤ 0.001). T-tests revealed significantly greater high intensity jumps (65 ± 25.9) during the scrimmage relative to practice (32.3 ± 19.3, p < 0.036). Conversely, HRmax and time spent in HRzone3 and HRzone4 were significantly lower in the scrimmage relative to preseason practice sessions (p > 0.253).
Conclusions: There was an inverse trend between heart rate intensities and high intensity jumps throughout preseason practices and a competitive scrimmage.
