Power recovery in the Wingate anaerobic test in girls and women following prior sprints of a short duration
Wingate anaerobic test
Chia, M. (2001). Power recovery in the Wingate anaerobic test in girls and women following prior sprints of a short duration. Biology of Sport, 18(1), 45-53.
The aim of the study was to compare between girls and women, the recovery of Wingate Anaerobic Test (WAnT) power after two prior sprints of 15 s duration with a short active recovery interval in-between the sprints. Participants with written informed consent were 19 girls (age: 13.6±1.0 yrs; body mass:
51.2±7.6 kg and stature: 1.59±0.06 m) and 21 women (age: 25.1±2.7 yrs; body mass: 57.9±7.7 kg and stature: 1.61±0.05 m). Lower limb muscle mass was determined using a dual-energy x-ray absorptiometric (DXA) procedure.
Following a standardised warm-up, each participant completed a series of three
15 s WAnTs, with each test separated by a 45 s active recovery interval. WAnT power variables were computed over 1 s time periods and were corrected for the
inertia of the cycle ergometer (Monark 834E). Whole blood lactate concentrations
(BL) were obtained immediately post warm-up and at three minutes after the completion of the third WAnT. Peak power (PP), expressed in watts per lower limb muscle mass (W·kg-1LLMM) were significantly greater in women than in girls in the frrst 15 s WAnT (46.1±10.9 vs. 37.4±2.3 W·kg- 1LLMM, P<0.05).
However mean power (MP) over the first test was not significantly different between the girls and women (33.8±2.1 vs. 34.7±5.9 W·kg-1LLMM, P>0.05). Girls were better able to replicate their power achieved in the first WAnT, in the third WAnT than women (mean of the differences±standard deviation of the differences for PP: 84±47 W vs. 174±84 W; MP: 81±45 W vs. 161±65 W, P<0.05). Despite
the better recovery in WAnT power in girls during the third 15 s cycle sprint, BL
taken at post- warm-up (2.5±0.5 vs. 1.9±0.5 mM·L-1, P>0.05), and at three . min
post exercise (9.2±1.2 vs. 8.4±1.3 mM·L- 1
, P>0.05) were not significantly different
in girls and women.
