Background: This study investigated the effects of long term betaine supplementation on body composition, performance, and homocysteine thiolactone (HCTL) in experienced strength trained men.
Methods: Twenty-three subjects were matched for training experience (4.8 ± 2.
Purpose: To examine the effect of betaine supplementation on cycling sprint performance.
Methods: Sixteen recreationally active subjects (7 females and 9 males) completed three sprint tests, each consisting of four 12 sec efforts against a resistance equal to 5.5% of body weight; efforts were separated by 2.
Background: We investigated the ergogenic effects of betaine (B) supplementation on strength and power performance.
Methods: Twelve men (mean +/- SD age, 21 +/- 3 yr; mass, 79.1 +/- 10.
Background: This study was developed to establish whether betaine was present in the sweat of females and to determine any correlations with other sweat components.
Methods: Sweat patches were placed on eight trained adolescent Highland dancers (age = 13.6 +/- 2.
