Intermittent Fasting Promotes Weight Loss without Decreasing Performance in Taekwondo

Intermittent fasting (IF) is commonly used by combat sports athletes for weight loss. However, IF can decrease performance. This study aimed to investigate the effect of on total body mass (TBM) and Taekwondo Nine (seven male, two female; 18.4 ± 3.3 years) underwent 4 weeks 12 h IF. TBM, countermovement jump (CMJ), mean kicks (MK), number (TNK) were compared weekly. Performance was measured in fed state (FED) fast (FAST). Results showed decreased TBM week 1 (62.20 6.56 kg; p = 0.001) 2 (62.38 6.83 0.022) pre-intervention (63.58 6.57 kg), stabilizing 3 (62.42 6.12 no significant change (63.36 6.20 kg). CMJ performance lower FED (35.26 7.15 cm) than FAST (37.36 6.77 cm; 0.003), but 3, (38.24 6.45 higher (35.96 5.05 0.047). No differences found MK TNK FSKTmult.
