Abstract:Abstract

Cinematographical analysis was used to compare spatial and temporal relationships of ten skilled and ten non-skilled performances of the standing broad jump. Means of the extent and duration of major joint action for the two levels of skill were represented graphically. Characteristic likenesses appeared in the general patterns of movement of limbs and in proportion of time consumed by the phases of the movement. Characteristic differences were found in angles of take-off and of landing and in extent and duration of specific joint actions. Greater extent of movement occurred in the skilled performances. The latter characteristically used more time in hip flexion and less time in knee extension.
Keywords:measurement and evaluation  reliability  testing  test theory  interclass reliability  intraclass reliability
