Jal. Calbet et al., FRACTIONAL USE OF ANAEROBIC CAPACITY DURING A 30-S AND A 45-S WINGATETEST, European journal of applied physiology and occupational physiology, 76(4), 1997, pp. 308-313
This study examined the suitability of the Wingate test as a means of
assessing the maximal oxygen deficit (MOD), and the influence of the a
naerobic capacity on the fraction of the MOD used during a 30- and a 4
5-s Wingate test in 19 male subjects. The MOD incurred in constant-int
ensity supramaximal exercise was higher (P < 0.01) than that for the 4
5-s and 30-s Wingate tests [65.6 (3.4) vs 60.9 (2.2) and 53.7 (1.6) ml
. kg(-1), respectively], corresponding to a 10% higher value for the
45-s compared to that for the 30-s test (P < 0.001). A close correlati
on was found to occur between MOD and the oxygen deficit incurred duri
ng the 30- and 45-s Wingate tests, as well as between both all-out tes
ts (r = 0.86-0.90; P < 0.001). The oxygen deficit accumulated during t
he first 30 s of the 45-s Wingate test was similar to that accumulated
during the 30-s Wingate test. The intraclass correlation coefficient
for the oxygen deficit after 30 s of all-out exercise (two treatments)
was 0.96. The higher the MOD the lower was its fractional recruitment
during the 30-s (r = -0.88, P < 0.001) and during the 45-s (r = -0.74
, P < 0.01) Wingate tests. In conclusion, 80-90% as an assessment of t
he oxygen deficit incurred during a Wingate test is valid as an estima
te of the anaerobic capacity. The fraction of the anaerobic capacity u
sed in a 30- and 45-s all-out test in inversely related to the anaerob
ic capacity.
