Abstract

Purpose:To assess the effects of different modes of morning (AM) exercise on afternoon (PM) performance and salivary hormone responses in professional rugby union players.Methods:On 4 occasions (randomized, crossover design), 15 professional rugby players provided AM (~8 AM) and PM (~2 PM) saliva sa...

Control (passive rest), weights (bench press: 5 &#xD7; 10 repetitions, 75% 1-repetition maximum, 90-s intraset recovery), cycling (6 &#xD7; 6-s maximal sprint cycling, 7.5% body mass load, 54-s intraset recovery), and running (6 &#xD7; 40-m maximal sprints, 20-s intraset recovery) interventions preceded (~5 h) PM testing.Results:PM sprint performance improved (P &lt; .05) after weights (&gt;0.15 &#xB1; 0.19 s, &gt;2.04% &#xB1; 2.46%) and running (&gt;0.15 &#xB1; 0.17 s, &gt;2.12% &#xB1; 2.22%) but not cycling (P &gt; .05). PM jump height increased after cycling (0.012 &#xB1; 0.009 m, 2.31% &#xB1; 1.76%, P &lt; .001) and running (0.020 &#xB1; 0.009 m, 3.90% &#xB1; 1.79%, P &lt; .001) but not weights (P = .936). Reaction time remained unchanged between trials (P = .379). Relative to control (131 &#xB1; 21 pg/mL), PM testosterone was greater in weights (21 &#xB1; 23 pg/mL, 17% &#xB1; 18%, P = .002) and running (28 &#xB1; 26 pg/mL, 22% &#xB1; 20%, P = .001) but not cycling (P = .072).
