Methods<\/jats:bold>:<\/jats:italic> Forty-four (32 men and 12 women) junior cross-country skiers were randomly assigned into a low-intensity training group (LITG, n\u2009=\u200920) or high-intensity training group (HITG, n\u2009=\u200924) for an 8-week intervention followed by 5 weeks of standardized training with similar intensity distribution, and thereafter 14 weeks of self-chosen training. Performance and physiological indices in running and in roller-ski skating were determined preintervention, after the intervention, and after the standardized training period. Roller-ski skating was also tested after the period of self-chosen training. Results<\/jats:bold>:<\/jats:italic> No between-groups changes from preintervention to after the standardized training period were found in peak speed when incremental running and roller-ski skating (P<\/jats:italic>\u2009=\u2009.83 and .51), although performance in both modes was improved in the LITG (2.4% [4.6%] and 3.3% [3.3%], P<\/jats:italic>\u2009<\u2009.05) and in roller-ski skating for HITG (2.6% [3.1%], P<\/jats:italic>\u2009<\u2009.01). While improvements in maximal oxygen consumption running and peak oxygen uptake roller-ski skating were greater in HITG than in LITG from preintervention to after the intervention, no between-groups differences were found from preintervention to after the standardized training period (P<\/jats:italic>\u2009=\u2009.50 and .46), although peak oxygen uptake in roller-ski skating significantly improved in HITG (5.7% [7.0%], P<\/jats:italic> < .01). No changes either within or between groups were found after the period of self-chosen training. Conclusions<\/jats:bold>:<\/jats:italic> Differences in adaptations elicited by a short-term intervention focusing on low- versus high-intensity endurance training had little or no effect on the subsequent development of performance or physiological indices following a period of standardized training in cross-country skiers.<\/jats:p>","DOI":"10.1123\/ijspp.2021-0356","type":"journal-article","created":{"date-parts":[[2022,2,7]],"date-time":"2022-02-07T10:33:47Z","timestamp":1644230027000},"page":"594-604","source":"Crossref","is-referenced-by-count":2,"title":["How
