topicZma Sleep Randomized Trial
claimThe goal of the present study was to determine whether an acute dose of a zinc-containing nutritional supplement (ZMA) has any effects on sleep and morning performance in recreationally trained males.

topicZma Sleep Randomized Trial
claimNineteen males participated in a repeated-measures within-subjects study to assess objective and subjective measures of sleep, completed counter-movement jumps (CMJ) and repeated sprint morning performance (RSP).

topicZma Sleep Randomized Trial
claimResults A main effect for "sleep" (4 or 8 h) was found, where more opportunity to sleep resulted in better "sleep" metrics (both objective and subjective) as well as better Stroop scores (lower colour-interference and word-interference scores and lower error in words).

topicZma Sleep Randomized Trial
claimNo main effect for "Pill" was found other than the mood state depression, where subjective ratings for the PLAC group were lower than the other two conditions.

topicZma Sleep Randomized Trial
claimPurpose Purpose: We examined whether supplementation of zinc magnesium aspartate (ZMA) in two groups of males, either partially sleep-restricted (4 h) or with habitual sleep (8 h) for 2 nights, was beneficial for sleep and subsequent morning Stroop performance.
