Table 4.
The %-contribution of total race time of the start, turn, and free-swimming (swim) section of the eight finalists (fastest) compared to the eight slowest swimmers from the heats by a 2-way analysis of variance (ANOVA). Race times between fastest and slowest swimmers were compared with an unpaired t-test.
