Table 1 Description of the agility and power subscale items of the PERF-FIT

Running^a

The child runs as fast as possible in the ladder, one foot per square, runs around the bottle and returns the same way. The time (s) taken to complete this 8-m run and the number of mistakes (touching the ladder, stepping outside the ladder, skipping a square or losing balance) are recorded.

Stepping^a

The child steps with two feet in each square as fast as possible, runs around the bottle and returns the same way. The time (s) taken to complete this this 8-m run and the number of mistakes (touching the ladder, stepping outside the ladder, skipping a square or losing balance) are recorded.

Side jump^a

The child jumps sideways on its feet, with one foot per square, in the same three squares of the agility ladder. The total number of correct landings in 15 s is recorded (anaerobic muscle endurance). If toes or heels touch the sidebars of the ladder, the landing is not counted. If the child steps outside the ladder or falls on the floor, only the correct landings before losing balance are counted.

Standing long jump

The child jumps forward as far as possible and lands on its feet in a controlled and balanced manner. The distance between the starting line and the heel of the foot that landed closest to the starting line is measured (cm).

Overhead throw

The child kneels just behind the starting line and throws a sandbag (2 kg) forward as far as possible. The child holds the sandbag behind the head (starting position). The distance between the starting line and the part of the sandbag closest to the starting line is measured (cm).
