1 INTRODUCTION Originally introduced in 1984 by Alois Mader (Mader, 1984), the maximal glycolytic rate (νLa.max) has recently resurrected as a surrogate of anaerobic glycolytic exercise performance (Langley et al., 2024; Park et al., 2021; Quittmann, Schwarz, et al., 2021; Yang et al., 2023). Meanwhile νLa.max also gained popularity in the field of athletic testing, as it is frequently discussed in various online forums (Xxxx, 2024a, 2024b, 2024c).

In combat sports such as taekwondo (TKD), athletes rapidly reduce body weight to achieve a desired weight category. Competition takes place 16–24 h after weigh-in and thus, the recovery time is an important factor for competition performance. The purpose of this study was to investigate the impact of rapid weight reduction (RWR) on athletic performance and associated hemorheological properties considering relevant recovery time. Five male TKD athletes reduced body weight by 5% within 3½ days.
