Abstract We evaluated associations between muscle phenotype, positional role, and on‐ice performance in male U20 Danish national team ice hockey players. Sixteen players (10 forwards, six defensemen) participated in a game with activity tracking. R

Abstract Background Risk factors for chronic disease, including low cardiorespiratory fitness levels (VO2max), are often present in middle-aged populations. We aimed to evaluate the efficacy of a motivational, individual, and locally anchored physica

Andersen, O E, Kristensen, A M, Nielsen, O B & Overgaard, K 2023, ' Force potentiation during eccentric contractions in rat skeletal muscle ', Journal of applied physiology (Bethesda, Md. : 1985), vol. 134, no. 3, pp. 777-785 . https://doi.org/10.1152/japplphysiol.00676.2022
Postactivation potentiation refers to an acute enhancement of contractile properties following muscle activity. Previously, the effects of prior muscle activation on eccentric force at tetanic activation frequencies have only been sparsely reported.

Low-frequency fatigue (LFF) is defined by a relatively larger deficit in isometric force elicited by low-frequency electrical stimulation compared with high-frequency stimulation. However, the effects of LFF on power during dynamic contractions elici

Abstract The purpose of this study was to compare the effect of a 6‐week period of knee flexion strength training at either optimal or short muscle length, on length‐specific muscle strength and fatigue. Twelve healthy volunteers performed dynami

Objective: To investigate (1) how current and pulse frequency of electrical stimulation (ES) as well as contraction mode (isometric, concentric, and eccentric) influence torque output and discomfort and (2) how familiarization by repeated ES sessions

The influence of moderately elevated extracellular potassium concentration ([K+]) on muscle force has marked similarities to that of posttetanic potentiation (PTP) in that twitch force may be enhanced whilst high-frequency force is depressed. The pur

Background and Aim: Physical activity confers health benefits in many diseases but remains almost unstudied for cirrhosis. We investigated whether a period of resistance training affects the subsequent long-term risk of hospitalization or mortality a

Moderate elevations of extracellular K+ concentration ([K+]o) occur during exercise and have been shown to potentiate force during contractions elicited with subtetanic frequencies. Here, we investigated whether lactic acid (reduced chloride conducta
