Abstract
The purpose of the investigation was to compare contraction periods on two test conditions to assess isometric muscular strength in elementary school girls. Test conditions included a 2-s make and 5-s make test with the order of the tests counterbalanced. Twenty-five girls aged 9–11 were assessed with a hand held dynamometer on two separate occasions 5–7 days apart. Muscle groups were tested alternating body sides and upper and lower muscle groups including hip flexion, knee extension, elbow flexion and shoulder abduction. Based on the data analysis, it was concluded that either contraction period with the make-test procedure was sufficient to assess isometric muscular strength in elementary school girls.
