Background. The long jump is technically divided into four stages: run-up, jump, flight and landing. The total measured distance of the long jump consists of the sum of these three lengths: take-off distance (L1), flight distance (L2) and landing distance (L3). The parts of the long jump were examined to determine by analyzing the various kinematic variables such as the percentage of L1, L2 and L3 rates in previous studies.
Aims. The aim of this study was to determine whether there is a relationship between flexibility ability and selected variables of long jump performance components, particularly the landing distance (L3) for teenage athletes.
Methods. The research group comprised 32 male athletes, age 16.2 ± 0.6 years, who participated in the qualification round in the Turkey Youth Indoor Championships. All trials of the athletes were recorded and a two-dimensional analysis of their best performances was made. Velocity values (V10) of the last 10 meters of the approach run of the athletes, contact time at take-off, take-off angle, and long jump performance component (L1, L2, L3) values were calculated.
Result. When the relationship between the flexibility ability and other performance components of the athletes was examined, only a weak statistically significant correlation was found between the approach run velocity and flexibility (r=0.45). Various studies have been conducted in different events, examining the effects of flexibility on sprint and jumping ability.
Conclusions. Due to the L3 similarity of the body position in landing with the sit & reach test, the anticipated relationships were not found except for V10.
