The Verification of the Use of the Heart Rate Variability in the Management of Training Process in Adolescent Mountain Bikers
 KADLEC, Jakub
Cross-country Olympic (XCO) is one of the endurance sports. The training process of mountain bikers is very demanding because the rider must be complex in endurance and anaerobic skills. Alfa and omega of the training process is a periodization of training load and recovery. Heart rate variability (HRV) can help us assess body's condition and readiness for training. In the practical part of the work, an experiment was carried out, which was attended by eight adolescent mountain bikers. The intervention took place during the training camp. The total intervention time was four weeks. The participants were randomized into two groups. The first experimental group (ES) (n = 4) was a graduated training camp with a heart rate variability guided training load. The second group was a control group that used a classical predefined training plan. For evaluation of HRV training efficiency a VO2max test and 20 minutes time trial (20TT) on an ergometer were used. The results showed an improvement in mean power output during 20TT in the experimental group (PRE 303.5 W; POST 317.5 W) and relative values (PRE 4.58 W.kg-1; POST 4.68 W.kg-1). On the other hand, there were no changes in average power (PRE 308 W; POST 305.7 W) and relative values (PRE 4.20 W.kg-1; POST 4.20 W.kg-1). From a statistical point of view, there was no effect of HRV training on performance indicators (p <0.05). Our experiment failed to confirm the usefulness of HRV training for cyclists.
