How can work load during very short periods of high intensity exercise interspersed with longer periods of low intensity exercise or

standing still be monitored?

Resting Heart Rate• Norm: 40-60 beats per minute• influenced by training status

Maximal Heart Rate• Norm: (for active, adult players ) • between 160-220+ • decreases with increasing age• no reflection of training status

Why measure Why measure heartheart--rrate ?ate ?

• To improve football specific endurance capacity

• To make the training as football specific as

possible

• To reduce the time spent on training without the

ball

AFC COACH EDUCATION

Why measure Why measure heartheart--rrate ?ate ?• to educate coaches and players• to monitor exercise intensity during drills with the

ball• to control exercise intensity during drills with the

ball• to monitor fitness levels• to minimise risk of “over-training”

• to monitor exercise intensity during rehabilitation

AFC COACH EDUCATION

Training drills with the ball Training drills with the ball ensures that...ensures that...

• specific muscle groups used in football are trained

• players develop technical and tactical skills under conditions similar to those encountered in a match (stress)

• there is greater motivation for players compared

to running without the ball
