The purpose of this study was to examine the effects of two braking forces (8.7% and 11% of body mass, BM) on Wingate test performance, peak lactate ([La]pk), peak heart rate (HRpk), and rate of perceived exertion (RPE). Sixteen male physical education students (age: 22.7 +/- 1.3 years, height: 1.81 +/- 0.07 m, body mass: 74.3 +/- 9.6 kg) performed, in randomized order, two Wingate tests at 8.7% BM and two Wingate tests at 11% BM on a Monark cycle ergometer during four separate sessions.The results showed that the reliability level of mechanical measures was not affected by the braking force and was relatively similar for each variable in both braking forces (0.886 < ICC < 0.985). In addition, peak power, mean power, fatigue slope, and RPE were significantly higher (8.2%, 7.0%, 11.9%, and 4.1%, respectively, all p < 0.05) using a braking force of 11% BM compared to 8.7% BM, whereas there was no significant effect of braking force on [La]pk and HRpk. In conclusion, the results of the present study suggested that the reliability of the Wingate test does not depend on the used load, and a braking force of 11% BM is more optimal for power output during Wingate test in active adults.
