Maxime :
200m 4 nages : 3min 11sec 62cent. 191.62sec
Vitesse (v) = distance/temps v = 200/191.62 = 1.04m/s
Amplitude (a) = distance/nombre de cycle
Fréquence (f) = nombre de cycle/temps
1er 50m papillon : 40’’27
v1 = 50/40.27 = 1.24m/s
a1 = 50/21 = 2.38m/cycle
f1= 21/(40.27/60) = 31.29cycles/min
2éme 50m dos : 52’’54 temps de passage : 1’32’’81
v2 = 50/52.54 = 0.95m/s
a2 = 50/ (47/2) = 2.13m/cycle
f2 = 23.5/(52.54/60) = 26.83cycles/min
3éme 50m brasse : 55’’47 temps de passage : 2’28’’28
v3 = 50/55.47 = 0.90m/s
a3 = 50/27 = 1.85m/cycle
f3 = 27/(55.47/60) = 29.20cycles/min
4éme 50m crawl : 43’’34 temps de passage : 3’11’’62
v4 = 50/43.34 = 1.15m/s
a4 = 50/ (46/2) = 2.17m/cycle
f4 = 23/(43.34/60) = 31.84cycles/min
