The Postseason Transition Phase in Ice Hockey: Detraining, Diagnostics, and Management

The transition phase between competitive seasons in ice hockey has received limited attention in the strength and conditioning literature. After 6–8 months of intermittent high-intensity competition, players accumulate substantial neuromuscular, metabolic, and psychological fatigue, yet management of the weeks after the final game lacks consensus guidance. This article addresses 3 questions: what is lost physiologically during the postseason transition and how quickly; which diagnostic tools provide actionable information during this window; and how the phase should be managed across competitive levels. Maximal oxygen uptake declines by 4–14% within 4 weeks of training cessation in highly trained athletes, anaerobic threshold by 11–23% over 3–12 weeks, and sport-specific power can decline while general strength is maintained. Body composition deteriorates when in-season energy intake persists after training volume drops. A 2-stage diagnostic approach, 5–7 days and 3–4 weeks after the final match, provides the data needed to plan the phase. Skating-specific modalities such as the slide board offer practical off-ice alternatives. Nutrition is central rather than peripheral: protein should remain at 1.6–2.0 g·kg −1 ·d −1 while carbohydrate is matched to reduced training volume. Recommendations are differentiated for senior professional, junior, and subelite players.
