Abstract text Introduction Warm-up (WU) generally increased swimming performance (Neiva et al. 2014). However, WU procedure appeared complex especially among disable-body swimmers in a warm and humid pool environment. Some athletes were also able to determine the optimal WU intensity (Balilionis et al. 2012) but not for others (Mandengue et al. 2005). Additionally it was observed a greater performance after an intermittent (IWU) compared to continuous (CWU) WU modalities but this effect would depend on WU duration (Balilionis et al. 2012) and intensity (Bishop D. 2003). Hence, the aim of this study was to compare freestyle performance in Paralympic swimmers (PS) after self-select WU (SSWU), IWU and CWU modalities. Methods 17 trained PS (21.6±8.3y, IPC classification: S3-S15) performed 100-m freestyle trials on separate days after 20min of SSWU, CWU or IWU. The critical velocity (CV) was used to determine intensity of CWU and IWU (Wakayoshi et al. 1992). SSWU replicated the swimmers’ usual precompetition strategy. Swimming performance, WU covered distance, blood lactate 3min after WU (3Lact) and the difference between peak recovery – 3Lact values (ΔLact) were assessed. Results The mean VC was 1.013±0.22m.s-1. Individual data indicated that 46.7% of PS swam fastest after SSWU, 33.3% after IWU and 20.0% after CWU. WU covered distances were different between IWU (921±155m), CWU (1182±230m) and SSWU (1234±1342m) (P<0.05). All WU modalities induced a positive ΔLact (P<0.001) with no WU modalities interaction. Swimming performance was inversely correlated with covered distance (-0.66, P<0.001) and ΔLact (-0.67, P<0.001). 3Lact was negatively related to ΔLact (-0.33, P= 0.03). Discussion SSWU strategy could be adapted for swimming fastest but inter-individual variability observed in their regular routine interacted on the performance. Balilionis et al. (2012) and Mandengue et al. (2005) already observed that some able-body athletes needed a controlled WU to optimize their performance. Each mean WU modalities on the present study also induced to swim a moderate distance - between 1,000 and 1,500m - according recent recommendations (Neiva et al. 2013). However, lower is the covered distance during warm-up, shorter was the swimming time. Thus, intermittent sets at CV could be the better strategy compared to self-select or continuous WU modalities to optimize the subsequent performance in Paralympic swimmers. Balilionis et al.
