- Abstract
In response to the need to adjust training loads of sprinters in speed sessions, due to the large variability in the number of repetitions that coaches use and their ignorance of how many repetitions to execute, when to stop training, or what tools to use to optimally monitor speed session training, this study was carried out, in which we assess the relationship between the degree of load and fatigue, which was measured through speed loss and jump ability as well as metabolic stress. Eighteen national- and internationallevel sprinters participated. They completed 40m, 60m, and 80m sprints at maximum speed until they lost 3% of their speed. This was carried out in three different sessions with one week between each session. Before and after each sprint they executed three countermovement jumps (CMJ), and lactate was measured in the first and last repetitions. The losses produced in the successive sprints presented a strong relationship between the distances and the reduction in CMJ height. For the 40m run, this loss was equivalent to the speed loss, 3.1% for 40m, though it increased to 6.7% for 60m and to 8.3% for 80m. This relationship between reduction in CMJ height and distances run could be used as an indicator of the degree of fatigue produced by various types of efforts, and, therefore, it would be useful for monitoring and dosage of training load.
