Mean ±s.e.m.n = 8 per group.

P < 0.05

^**

P < 0.01, significantly different from baseline value.

^†

P < 0.05

^††

P < 0.01, significantly different from IRL at corresponding time.

Values in parentheses represent percentage changes from baseline values. Definitions as in Table 2. The IRL and IRL-CTRL values are the mean of two trials performed on different days.
