New study: Association between Subjective Indicators of Recovery Status and Heart Rate Variability among Divison-1 Sprint-Swimmers

Our latest study investigates the relationship between subjective indicators of recovery status and HRV among NCAA Division 1 sprint-swimmers. The main findings were: 1) Perceived sleep quality showed the strongest relationship with post-waking LnRMSSD. 2) LnRMSSD demonstrated stronger associations with … Continue reading

Effects of varying training load on HRV and running performance among an Olympic rugby sevens team

This study is the first of a few collaborations between Dan Howells and I involving HRV in elite rugby sevens players. Here we evaluated HRV and running performance responses  to peak training loads during preparation for the 2016 Olympic games. … Continue reading

Revisiting 60-s HRV recordings vs. Criterion in athletes

I’ve recently had the pleasure of peer-reviewing a few very well-written and carried out studies investigating duration requirements for stabilization preceding HRV recordings by different research groups. I look forward to seeing the published versions as the quality of the … Continue reading

HRV responses to in-season training among D-1 college football players

During spring training camp, we found that Linemen demonstrate the greatest reductions in LnRMSSD at ~20 h post-training, followed by Mid-Skill and Skill, possibly reflecting inadequate cardiovascular recovery between consecutive-day sessions for the larger players, despite lower PlayerLoad values. (Full-text … Continue reading

Ultra-short SDNN:RMSSD ratio strongly relates with LF:HF ratio in athletes

Our latest methodological study suggests that the SDNN:RMSSD ratio derived from a 60-sec recording may be a more convenient alternative to the traditional LF:HF ratio in athletes. Ultra-shortened time-domain HRV parameters at rest and following exercise in athletes: an alternative … Continue reading
