A Submaximal Running Test With Post-Exercise Cardiac Autonomic And Neuromuscular Function In Monitoring Endurance Training Adaptation.
The aim of this study was to investigate whether a submaximal running test (SRT) with post-exercise heart rate recovery, heart rate variability and countermovement jump measurements could be used to monitor endurance training adaptation. Thirty-five endurance trained men and women completed an 18-week endurance training program. Maximal endurance performance and maximal oxygen uptake were measured every eight weeks. In addition, SRT with post-exercise heart rate recovery, heart rate variability and countermovement jump measurements were performed every four weeks. SRT consisted of two 6-minute stages at 70% and 80% of HRmax and a 3-minute stage at 90% HRmax, followed by a 2-minute recovery stage for measuring post-exercise heart rate recovery, heart rate variability and countermovement jump test. The highest responders according to the change of maximal endurance performance showed significant improvement in running speeds during stages 2 and 3 in SRT, while no changes were observed in the lowest responders. The strongest correlation was found between the change of maximal endurance performance and running speed during stage 3, while no significant relationships were found between the change of maximal endurance performance and the changes of post exercise heart rate recovery, heart rate variability and countermovement jump. Running speed at 90% HRmax intensity was the most sensitive variable to monitor adaptation to endurance training. The present submaximal test showed potential to monitor endurance training adaptation. Furthermore, it may serve a practical tool for athletes and coaches to evaluate weekly the effectiveness of training program without interfering normal training habits.
