CARDIO RESPIRATYORY ENDURANCE (aerobic endurance/stamina)

 

Definition

Cardio Respiratory Endurance is the ability of the heart and lungs to provide the working muscles with oxygenated blood for a prolonged period of time.

 

Impact on Performance

Poor CRE will result in the performer becoming breathless more quickly and unable to keep up with play or maintain a high skill level. Decision making may also be affected and longer rest periods will be needed to aid recovery. For example, Cardio Respiratory Endurance (CRE) is required in order to last the full 90 minutes of the game in football. During the game you will do a lot of work both on and off the ball. You will make repeated runs to support attacks, get into space to receive the ball, make runs with the ball, and chase back to defend etc. The energy required to do this is supplied aerobically, which requires your heart, lungs and blood system to supply oxygen to the working muscles throughout the game. Therefore a high level of CRE delays the onset of fatigue. This means that your work rate stays high so you can fulfil your role in the team and maintain a high skill level (as fatigue can also affect your control, touch, concentration and decision making).
