Figure 3. Workload, ratings of perceived exertion and repeated sprint ability during the repeated high‐intensity intermittent exercise protocol.

Figure 3

A and B, workload (A) and ratings of perceived exertion (RPE) (B) throughout the three periods (EX1–EX3) of high‐intensity intermittent exercise (10 × 45 s at ∼105% W max interspersed by 135 s of recovery between bouts and 10 min between periods. C, repeated sprint ability (RSA) (5 × 6 s sprints interspersed by 24 s of recovery) pre and post EX1–EX3. n = 18. Data are presented as means ± SD. *Significant difference compared to EX1 for workload and RPE scores and significant difference compared to pre for RSA. #Significant difference compared to EX2 for workload and compared to the post EX1 and EX2 values for RSA (P‐EX1 and P‐EX2). The dotted line in A represents the prescribed average work load in the 45‐s intervals.
