Abstract

Abstract Background Team handball is an intense sport with special requirements on technical and tactical skills as well as physical performance. The ability of handball players to make repeated powerful muscular contractions in pushing and throwing the ball is crucial to success. Objective This study investigated the effects of elastic band training on upper body peak power output, ball throwing velocity, and local muscle volume of junior handball players. Materials and Methods Thirty handball players (a single national-level Tunisian team) were randomly assigned to a control group (CG; n = 15) and an experimental group (EG; n = 15). Pre- and post-interventional measurements included force-velocity tests, one-repetition maximum (1RM) bench press and pull-over strength, ball throwing velocity in three types of throw (jumping shot, 3-step running throw, and standing throw), and anthropometric estimates of limb volumes. The EG additionally performed an elastic band training programme twice a week for 8 weeks immediately before engaging in regular handball training. The control group underwent no additional elastic band training. Results The EG demonstrated greater improvements in absolute and relative peak power (p < 0.001; 49.3 ± 22.9 % and 47.9 ± 24.6 %, respectively), 1RM strength (p < 0.001; 25.3 ± 2.2 % and 44.1 ± 9.0 % for 1RM bench press and pull over, respectively), and throwing velocity in all three types of ball throws (p < 0.001; 25.1–26.1 %), compared to the CG (3.9–4.4 %). Limb volumes increased significantly (p = 0.001, 8.0 ± 7.5 %) in the EG, with no significant change (p = 0.175, 2.6 ± 7.0 %) in the CG. Conclusions We conclude that additional elastic band training performed twice a week for 8 weeks improves measures relevant to game performance, particularly strength, power, and ball throwing velocity.
