Abstract
The purpose of this study was to determine whether mean power output in 30 seconds was greater in a paced effort test or an allout effort under optimal loading conditions. Nine male athletes volunteered to participate. All testing was done on a Monark cycle ergometer with continuous measurement of velocity and resistance. Power output was calculated (Resistance Velocity) and corrected for acceleration of the flywheel, For each subject, optimal resistance for peak power output was determined with 5 brief (7second) tests. Subsequently, 3 allout 30second tests using 80, 90 and 100% of this estimated optimal resistance, then 3 paced effort 30second tests were completed on separate days. Pacing was accomplished with velocity feedback at 80, 100 or 120% of optimal velocity calculated from the allout tests. Subjects were encouraged to try to exceed the target velocity if possible during the final 10 seconds of the paced effort test. The best allout test (772 +/ 35W) was notdifferent (paired t test, p=0.31) from the best paced effort test (787 +/ 27 W). Furthermore, there was no significant difference between mean power output in the allout tests at 90% (736 +/ 28 W) and 100% (766 +/ 36 W) of estimated optimal resistance for peak power output (1.16 +/ 0.05 N.kg(1)), but mean power at 80% of the estimated optimal resistance was lower (722 +/ 31 VV; ANOVA for repeated measures, p<0.05). In conclusion, a paced effort test does not permit greater mean power output over 30 seconds than an allout test, and there is considerable latitude in apparent optimal resistance for mean power output in a 30second test.
