View larger version (24K): [in a new window]   Fig. 1. Box plots for log-transformed (A) maximal instantaneous velocity (in m s–1), (B) acceleration (in m s–2), (C) deceleration (in m s–2) and (D) mass-specific power output (in W kg–1) for each experimental temperature (15, 20, 25, 30, 35°C). Values with the same letter (a,b) denote temperatures at which performance measures are not significantly different, as indicated by pairwise post-hoc tests. No letter indicates that a performance measure at a given temperature is significantly different for measures at all other temperatures. For each box plot, the line within the box represents the mean; the top and bottom of each box represent the 75th and 25th percentiles, respectively; the top and bottom whiskers represent the 95th and 5th percentiles, respectively; the asterisk represents an outlying datum.

Values with the same letters (a–d) denote temperatures at which kinematic measures are not significantly different, as indicated by pairwise post-hoc tests. No letter indicates that a performance measure at a given temperature is significantly different for measures at all other temperatures. For each box plot, the line within the box represents the mean; the top and bottom of each box represent the 75th and 25th percentiles, respectively; the top and bottom whiskers represent the 95th and 5th percentiles, respectively; asterisks represent data outlying >1.5 times the interquartile range, and circles represent data outlying >3 times the interquartile range.
