Key result
During a 10-day training camp, male canoeists undertook higher perceived training loads than females, resulting in higher total perceived stress and a small reduction in lnRMSSD.
Why the study?
During elite canoeing training camps, care to assure adaptation to avoid undesired fatigue is not always present, prompting the evaluation of sex-specific responses in perceived training loads, recovery, stress balance, and cardiac autonomic responses.
Does a 10-day training camp elicit sex-specific differences in perceived training loads, stress recovery, and heart rate variability in elite young canoe sprint athletes?

Does a 10-day training camp elicit sex-specific differences in perceived training loads, stress recovery, and heart rate variability in elite young canoe sprint athletes?
Elite male canoeists exhibit higher perceived training loads and stress, along with greater reductions in heart rate variability, compared to females during a 10-day training camp.
May indicate sex-specific load perception affecting HRV recovery in camps; hypothesis-generating for tailored athlete monitoring.
Training camps are typical in elite Canoeing preparation, during which, the care to assure adaptation to avoid undesired fatigue is not always present. This study aimed identifying a specific sex response in perceived training loads, recovery and stress balance, and cardiac autonomic responses. Twenty-one elite athletes (11 males and 10 females) of the Portuguese Canoeing National team participated in the investigation. The daily HRV (lnRMSSD) was monitored. The (RESTQ-52) questionnaire was used to access the recovery and stress state. The 10-day training camp was composed of two consecutive 5-day periods (P1 and P2). Data analyses were performed using confidence limits, effect size, and magnitude-based inference. In the females, Session rating of perceived exertion (sRPE), lnRMSSD, and its coefficient of variation did not change between P1 and P2. However, in males, lnRMSSD showed a small reduction from P1 to P2. Also, sRPE was higher in males over the training period, with a possibly small difference at P2. Regarding RESTQ-52, total stress most likely increased with large and very large differences in males and moderate differences in females during the training period. Male canoeists undertook higher perceived training loads than females, with a consequent higher level of total perceived stress and lnRMSSD during a 10-day training camp.

Coelho et al. (2019) conducted an observational in Elite young canoe sprint athletes (n=21). 10-day training camp vs. Females was evaluated on Perceived training loads, recovery and stress balance, and cardiac autonomic responses. During a 10-day training camp, male canoeists undertook higher perceived training loads than females, resulting in higher total perceived stress and a small reduction in lnRMSSD.
