Abstract
Abstract: Objective: The objective of this study was to examine the influence of variability in training load on performance increase in elite rowers. Methods: fourteen elite rowers (3 light, 11 heavy, age: 23.0 ± 1.5 years, length: 192.0 ± 6.6 em, weight: 86.0 ± 9.4 kg) were followed during 14 weeks of training, divided into three periods of 4 to 5 weeks. Subjects filled in a daily training log with session duration and session rates of perceived exertion. Based on training log data, Weekly Load (WL) and Monotony (M), as a measure of training load variability, were calculated as mean ± SD per week.At baseline and at the end of each period of 4 to 5 weeks, subjects performed a Submaximal Ergometer Rowing Test (SERT) at a predetermined percentage of maximal heart rate, to asses power output. Data was analysed for the total group and for individuals. Results: Group analysis: WL and M showed a significant positive correlation (r=0.77, p<0.01). Some significant positive correlations were found between WL and performance, and both negative and positive significant correlations were found between M and performance, but no clear pattern was observed. Individual analysis: To illustrate individual variability in the relation between training load variability and performance, data of a light and a heavy weight rower was analyzed. For the light weight rower it was shown that increases in WL and M were related to performance decline on the SERT, and values of M increased significantly when values of WL increased (r=0.95, p<0.01, N=14). For the heavy weight rower, performance decreased when the variation in training load between weeks was high, and when levels of M were high. Also values of M increased significantly when values of WL increased (r=0.78, p<0.01, N=14). Conclusion: Our study showed that increases in WLwere related to increases in M. However, high M values seem to be detrimental to performance. Therefore it is suggested that when weekly training loads are high, M should be kept low (<2) by implementing more variability in training load. Relationships between training load, training load variability and performance differ between individuals. To maximally improve performance, training load and training variability should be adapted individually.
