It was hypothesized that some characteristics of the positions adopted by long jumpers during the final strides of the approach are significantly related to the distance of the jump,position variables were significantly related to the distance of the jump, through their relationships with the velocity of the approach and the vertical velocity of the CG at takeoff into the jumphe techniques used during the final strides of the approach, the role of elastic energy in the takeoff, the initiation and control of the jumper's angular momentum, and the techniques used in the landing. This is very unfortunate because the takeoff phase is by far the most critical of the four phases to the

success of the performance (Linger, 1980; and Stewart,
1981; Ramey, 1982).Finally, in Stage 4 the jumper learns to coordinate the swinging body segments with the movements previously
learned. Each of these distances as well as the total distance jumped is greatly affected by the takeoff variableThe flight distance, which accounts for most of the total distance, is also determined by a number of takeoff

variables, the most important being the resultant takeoff
From the discussion above it is clear that in order
to maximize flight distance, the takeoff actions must be
Even though the landing comes at the end of the jump,
the distance attained during this phase is also influenced
by the actions performed during the takeoff. Similar to the
takeoff distance, the landing distance is also determined
by the jumper’s physique and body’s configuration at
touchdown. The optimal configuration at touchdown is
one which allows the jumper to maximize distance by
extending his/her legs as far as possible in front of the
center of mass without falling backward (Dyson, 1977)
precisely timed and coordinated
