Leg power
• this is calculated by taking into account weight and
vertical jump. Expressed in relation to body weight
in kilogrammes, this is a good indicator of muscular
quality.

Strength-building tests
The goalkeeper’s maximal strength must be determined in
order to customise strength-building work for each muscle
group. The maximal load is the load which can be lifted
once. This is determined by:
• apparatus measuring muscular performance,
• direct method:
– lifting weights until failure,
• indirect method:
– the subject lifts a weight that is close to the maximal
load several times,
– the value of the load and the number of repetitions are
noted,
– the maximum load is calculated using:
the Brzycki formula:
Maximum
strength =
