Hydrolyzed collagen supplementation prior to resistance exercise augments collagen synthesis in a dose-response manner in resistance-trained, middle-aged men.

Resistance exercise (RE) increases collagen synthesis in young and older men, whereas hydrolyzed collagen (HC) ingestion improves this response to RE in a dose-response manner in young men. However, the collagen synthesis response to RE with and without HC in middle-aged men is unknown. Eight resistance-trained men (age: 49 ± 8 yr; height: 1.

Peak torque, rate of torque development and average torque of isometric ankle and elbow contractions show excellent test-retest reliability.

Background: Peak Torque (PT), Rate of Torque Development (RTD) and Average Torque (AT) over a single contraction assess the three components of muscle function during isometric contractions. Surprisingly, AT has never been reported or its reliability confirmed.

Objectives: This study aims to establish protocol reliability for ankle dorsiflexion and elbow extension isometric muscle function (PT, RTD, AT) in healthy participants using the Biodex System 3 Dynamometer.

The Neuromuscular Determinants of Unilateral Jump Performance in Soccer Players Are Direction-Specific.

Purpose: To investigate differences in neuromuscular factors between elite and nonelite players and to establish which factors underpin direction-specific unilateral jump performance.

Methods: Elite (n = 23; age, 18.1 [1.
