- Warm-Up, Post-Warm-Up, and Re-Warm-Up Strategies to Enhance Explosive Performance in Team SportPublication . Silva, Luís Miguel Correia da; Marinho, Daniel Almeida; Neiva, Henrique PereiraWarm-up is a fundamental component of competitive sports, contributing to performance optimization through physiological and neuromuscular adaptations. Despite its extensive use, the ideal structure of a warm-up remains poorly defined. In team sports, such as basketball and futsal, which involve frequent explosive efforts, it is important to understand the influence of warm-up, the post-warm-up period, and re-warm-up on performance. However, periods of inactivity before the start of the game, during substitutions, or at half-time may reduce athletes’ readiness and compromise explosive performance. The general objective of this thesis was to investigate the acute effects of different warm-up, post-warm-up, and re-warm-up strategies on explosive performance in team sports. To this end, four studies were conducted: (i) a systematic review of the effects of warm-up, post-warm-up, and re-warm-up strategies on explosive performance in team sports; (ii) an analysis of warm-up and re-warm-up practices of basketball coaches; (iii) an assessment of the effects of a warm-up protocol and different post-warm-up transition times; and (iv) an analysis of the effects of a re-warm-up protocol following different transition periods. The results indicated that short, progressive, high-intensity warm-ups may enhance explosive performance, and that brief re-warm-up protocols may help restore readiness during longer transitions. Overall, this thesis demonstrates that the warm-up, post-warm-up, and re-warm-up phases are complementary stages in an integrated preparatory process.
