Abstract Ice hockey is an intense team sport characterized by repeated bursts of fast‐paced skating, rapid changes in speed and direction frequent physical encounters. These are performed on‐ice shifts ~30–80 s interspersed with longer sequences passive recovery, resulting about 15–25 min time per player. Nearly 50% the distance covered at high‐intensity skating speeds accentuated activity pattern forwards compared to defensemen. During ice match‐play, both aerobic anaerobic energy systems...

Based on extrapolation of current trends in modern soccer, physiological loading has increased markedly, and the game will continue to become even more demanding future, which exacerbate fatigue at end a between games. Soccer is glycogen consuming activity due its high-intensity intermittent nature, muscle key factor associated with late game, as well determining recovery after or an intense training session. Low individual fibers subcellular compartments cell likely negatively affect...
This study aimed to examine the recovery kinetics (i.e., time-dependent changes) of performance-related variables between two 120-min male football games performed 3 d apart with and without carbohydrate supplementation.
We examined the degree of post-game fatigue and recovery pattern in various leg upper-body muscle groups after a simulated soccer game. Well-trained competitive male players (n = 12) participated study. The completed Copenhagen Soccer Test, 2 x 45 min protocol, following baseline measures maximal voluntary contractions multiple systemic markers damage inflammation at 0, 24 48 h into recovery. All had strength decrement (p ≤ 0.05) 0 post-match with knee flexors (14 ± 3%) hip abductors (6 1%)...
While it is well-established that a period of interval training performed at near maximal effort, such as speed endurance (SET), enhances intense exercise performance in well-trained individuals, less known about its effect on cardiac morphology and function well blood volume. To investigate this, we subjected 12 Under-20 Danish national team ice hockey players (age 18 ± 1 years, mean SD) to 4 weeks SET, consisting 6-10 × 20 s skating bouts effort interspersed by 2 min recovery conducted...
