Influence of different work and rest distributions on performance and fatigue during simulated team handball match play
This study investigated the effect of different interchange strategies on performance and pacing strategy during a simulated team-sport protocol. Eight youth male team handball players completed 2 conditions (LONGwork: 3 × 13:00 minutes, rest: 8:00 minutes; SHORTwork: 5 × 7:48 minutes, rest: 3:45 minutes). Participants were tested for 20-m sprint, countermovement jump, throwing performance, and heart rate (HR) during conditions. Postcondition measures included repeated shuttle-sprint and jump ability, session rating of perceived exertion, blood lactate, and glucose. Faster sprint (3.87 ± 0.27 seconds cf. 3.97 ± 0.24 seconds, effect size [ES] = 0.39, p = 0.03) and throwing performance (70.02 ± 7.40 km/h cf. 69.04 ± 5.57 km/h, p > 0.05, ES = -0.15) occurred in SHORT compared with LONG by a likely small difference. Higher summated HR (157 ± 21 cf. 150 ± 15 AU) occurred in SHORT compared with LONG by a likely small difference (ES = 0.37, p > 0.05). SHORT resulted in lower session rating of perceived exertion (224 ± 45 AU cf. 282 ± 35 AU, ES = 1.45, p = 0.001) and higher blood glucose (6.06 ± 0.69 mmol/l cf. 4.98 ± 1.10 mmol/l, ES = -1.17, p = 0.03) by a most likely moderate difference compared with LONG. Repeated shuttle sprint was better preserved after SHORT, with moderately lower 10 and 25 m times (p = 0.05). Interchange strategies using SHORT rather than LONG work and rest periods result in lower physiological load, leading to improved fatigue resistance and better preservation of high-intensity movements during matches.
