Calculs des données du 800m :
Vitesse du 800m NL : 13min12sec 792sec
vitesse (v) = distance/temps v = 800/792 = 1.01m/s = 3.64km/h
amplitude (a) = distance/nombre de cycle
fréquence (f) = nombre de cycle/temps
1er 200m : 3min5sec 185sec
v1 = 200/185 = 1.08m/s
a1 = 50/27 = 1.85m/cycle
f1= 27/(185/60) = 35.03cycles/min
2éme 200m : 3min27sec 207sec
v2 = 200/207 = 0.97m/s
a2 = 50/26.5 = 1.89m/cycle
f2 = 26.5/(207/60) = 30.07cycles/min
3éme 200m : 3min25sec 205sec
v3 = 200/205 = 0.98m/s
a3 = 50/26.5 = 1.89m/cycle
f3 = 26.5/(205/60) = 31.11cycles/min
4éme 200m : 3min15sec 195sec
v4 = 200/195 = 1.03m/s
a4 = 50/26 = 1.92m/cycle
