Probably the only parameter that can identify excessive overtraining is athletic performance, as performance is reflected by overall positive and negative adaptations to training.

It is a common finding that after high training load periods performance decreases. Nevertheless, coaches and athletes are looking for significant increases in performance after the recovery period.

  2. 2. Probably the strongest parameter that can identify excessive overtraining is athletic performance, as performance is reflected by overall positive and negative adaptations to training. It is a common finding that after high training load periods performance decreases. Nevertheless, coaches and athletes are looking for significant increases in performance after the recovery period (Figure1). This means that performance should always be measured to be correctly analyzed. Figure 1. Positive adaptation to multiple overload workouts SPORTLYZER ROWING ACADEMY
  3. 3. In most endurance athletes an incremental exercise test until exhaustion is regularly performed throughout the season as it enables to measure performance at several intensities (aerobic threshold, anaerobic threshold, VO2max, maximal performance). Also, multiple submaximal tests are performed to measure steady state levels at various intensities . The typical expectation from this test would be that the lactate performance curve will shift to the right that in general indicates an increased endurance performance (Figure 2).

  4. 4. Jeukendrup et al. (1994) have shown that lowered blood lactate profile may also be an indication of severe overtraining if maximal lactate concentrations at maximal intensity during the test are significantly decreased. It is usually noticed that the overtrained athlete is able to perform very well at training speeds but will be quickly exhausted at racing speeds. Therefore, for athletic performance analysis, maximal intensity tests or time trials are suggested, as they will most likely show the changes in exercise capacity (ability to sustain the specific intensity for certain time period) as a result of severe overtraining.

  5. 5. In conclusion Performance is the key marker of excessive overtraining. It is recommended to use maximal performance tests to get feedback, as during submaximal tests, performance might not be altered by overtraining. However, the submaximal intensity test, if performed until exhaustion, may be used. References • Hagerman FC. The physiology of competitive rowing. In: Exercise and Sport Science, W.
