For suitable training prescription it is important to obtain insight into the individual’s readiness to train on a regular basis. In this thesis, it will be investigated if countermovement jumping (CMJ) is an applicable tool to monitor readiness to train in short-track speed skaters. Therefore, three “basic” and three “specific” CMJ parameters are explored on responsiveness to fatigue (i.e. changes in acute training load) and on the relationship with subjective readiness to train. To do so, thirteen talented short-track athletes performed countermovement jumps twice a week over six weeks, and their daily training was monitored. For evaluation purposes, jump conditions were labeled as “fatigued” (internal load: 542 ± 145 AU) or “rested” (internal load: 0 AU) based on the preceding training session, and compared on differences via a one-way ANOVA. Pearson correlations were used to examine the relationship between CMJ parameters, subjective readiness to train and training load. The results demonstrated no significant differences between the “fatigued” and “rested” condition for any of the six CMJ parameters. Furthermore, no parameter demonstrated a significant relationship with training load. In addition, mean force, mean power, force at zero velocity and eccentric duration demonstrated small to moderate positive significant relationships with subjective readiness to train. Therefore, the results remain rather inconclusive, since contradictive to the hypothesis, the results indicate a poor responsiveness to changes in training load and therefore fatigue. Yet, the small to moderate correlations between subjective readiness and different CMJ parameters suggest at least a certain relationship between CMJ performance and subjective readiness to train.
