摘要：This study compared the differences in board velocity, stroke rate, and stroke length during 40-m maximal board paddling between elite and sub-elite paddlers. Sixteen Japanese male lifesavers (eight each of elite and sub-elite paddlers) performed 40-m maximal board paddling using the knee paddling (K-paddling) and prone paddling (P-paddling) techniques, respectively. Board velocity (BV), stroke rate (SR), and stroke length (SL) were calculated from video-recorded time trials. Board velocity was significantly higher in the elite group with both paddling techniques. The present study identified that the differences in the BVs between the two groups were mainly due to greater SL in K-paddling and higher SR in P-paddling, respectively, in the elite group. Furthermore, peak BVs were significantly related to SL with both paddling techniques in the elite group. Therefore, board paddlers and coaches should understand the differences in the SR-SL ratios for different performance levels based on the results of the present study. They should focus on the increases in the SL and SR values for K-paddling and P-paddling, respectively, based on the SR-SL ratios of the elite group in the present study, when improving sub-elite paddlers' BV to reach elite paddler levels.
