Abstract
Dynamic changes have taken place in cross-country skiing in the last couple of years, among other things in terms of juniors also practising strength training. Therefore, as part of our research we focused on comparing the quantity and in one part also the content of strength training in junior cross-country skiing representatives in the annual training cycles 2010/ 2011 and 2019/ 2020.
Methodology: a retrospective analysis of training logs and plans of members of the Czech junior national team in cross-country skiing. Comparison of the monitored annual training cycles showed that strength training, particularly of a general focus, has increased for most junior national team members by 40 to 50 % compared with ten years ago.
Compared to the past, strength training is currently primarily developed as part of separate training units. Training methods are currently more fine-tuned and focused on individual sub-goals of strength training.
