The basic physical attributes I: Stamina.

Stamina is the basic physical attribute that allows us to do a specific type of exercise for the longest time possible without fatigue.

Types of Stamina:

1. Aerobic Stamina: medium-low intensity for a long period of time. You have enough oxygen and you can even tlak to someone who is running with you.
1. Aerobic power: 2-10' at 60-80% intensity.
2. Aerobic capacity: 10'-2h at 40-60% intensity.
3. Endurance: from 20 to several hours at 30-50% intensity
2. Anaerobic stamina: high intensity for the longest time possible. There is oxygen debt and lactic acid is produced in your organism and reduces the intensity of the effort. If you try to tlak to someone, you won't  be able to do it properly because the oxygen debt.
1. Alactic anaerobic stamina: very high intensity over a short time (untill 30"). Not time enough to produce lactic acid.
2. Lactic anaerobic stamina: very high intensity between 1 and 3'. Lactic acid is produced.
