Table 2. Comparison of total time for different start strategies.

Instant for initiating leg’s movement	Instant of finishing gliding with streamlined posture			Elapsed time of transition region (s)	Elapsed time of underwater leg’s movement(s)	Elapsed time of flight and diving	Total time (s)
Instant for initiating leg’s movement	Glide velocity (m/s)	Swimmer’s sway, heave, roll, pitch and yaw	Elapsed time for gliding with streamline posture (s)	Elapsed time of transition region (s)	Elapsed time of underwater leg’s movement(s)	Elapsed time of flight and diving	Total time (s)
Leg’s movement too soon	3.25	-0.004m、0.001m、0.2°、0.05°、0.02°	0.09	0.248	4.975	T	T+5.313
Optimal instant	2	-0.14m、0.038m、4.7°、 2.4°、1.3°	1.03	0	4.2	T	T+5.23
Leg’s movement too late	1.5	-0.32m、0.074m、8.1°、 4.25°、2.88°	1.68	0.286	3.4	T	T+5.366
