Figure 1:Mean (± SD) 30-s averaged power outputs for all subjects (n = 28) during the 3-min all-out critical power (CP) test. The error bars indicate standard deviations. The asterisks indicate a significant difference in CP estimates from the criterion (CP180) and the crosses (†) indicate a significant difference in anaerobic work capacity (AWC) estimates from the criterion (AWC180). The results indicated that 150-s was the shortest test duration that resulted in nonsignificant differences between the criterion (CP180 and AWC180) and estimated CP (CP150) and AWC (AWC150) values.
