Short-term tapering prior to the match: external and internal load quantification in top-level basketball

The purpose of this study was to compare accelerometry-derived external load and internal load calculated as a session rate of perceived exertion (sRPE) in elite male basketball over 3- days prior to the match and assessing players’ recovery status on the match-day. Thirteen professional basketball players participated in this study (age: 25.7±3.3 years ; height: 199.2±10.7 cm ; weight: 96.6±9.4 kg). All players belonged to a team competing in LigaEndesa (Spanish 1st Division) and Euroleague in the 2016/2017 season. Variables used in external motion analysis were: PlayerLoad (PL), accelerations and decelerations (ACC and DEC), jumps (JUMP) and changes of direction (CoD), in total (t) and high intensity (h) thresholds, while internal demands were registered using sRPE method. All variables were expressed in absolute (accumulated in the session) and relative values (per min of practice). For the evaluation of readiness, Total Quality of Recovery (TQR) questionnaire was used, measured in Arbitary Units (AU). The results showed differences in load and intensity (p<0.01) for almost all external (PL, hACC, tACC, hDEC, tDEC, hCoD and tCoD ; in both absolute and relative values) and internal (sRPE) variables as training sessions were closer to the match day or MD (MD-3>MD-2>MD-1). Only hJUMP, tJUMP and RPE variables showed no difference between MD-3 and MD-2, while both days significantly differed from MD-1. The average TQR score for all of the match days was 7.9±1.31 AU. This study showed differences in the amount of external and internal load between three days of training, where a team can be efficiently prepared for competitions by progressively decreasing the load over the 3-days prior to the match.
