Zusammenfassung
We assessed changes in maximal and explosive plantar flexion (PF) and dorsi flexion
(DF) torque, and thus the maximal and explosive DF/PF ratio, in response to succes-
sive badminton matches (2 × 35, 15 minutes of rest) in 16 juniors (10 males, 6 fe-
males) International-level badminton players before (Pre), immediately after the first
(Post- 1) and second (Post-2) match as well as after resting for 12 hours. For both PF
and DF, maximal voluntary torque decreased from Pre to Post-2 (~7%-9%; P < 0.05).
Compared with Pre, PF explosive voluntary torque decreased by ~4%-13% at Post-1
(P < 0.05), with further reductions ranging from −15% to −25% within the 0-100 ms
epoch after contraction (P < 0.001) at Post-2. Decrements of similar magnitude in
DF explosive voluntary torque occurred at Post-1 (ranging −7% to −27%) and Post-2
(ranging −3% to −28%) relative to Pre (P < 0.05). All neuromuscular parameters
were fully recovered after 12 hours of rest. Explosive DF/PF ratios during the very
initial phase of contraction (up to 50 ms from onset) were lower compared with the
maximal DF/PF ratio, with no effect of time (all P < 0.05). In badminton, explosive
torque indices should be included to more accurately reflect acute fatigue induced by
successive badminton matches.
