The aim of this study is to study the effects of eight-week static stretching exercises on jumping performance. The study included 18 male amateur footballers (age: 21,78±4,25 years; size: 180,11±6,38cm; body weight: 76,19±7,73kg) voluntarily. The participants’ flexibility, the vertical jump heights and the horizontal jump distances are measured using the Seating Access Test (OET), the Countermovement Jump (CMJ) protocol and the Standing Long Jump Test (DUAT). After the first measurements, participants were divided into two groups: random, germe (n=10) and control (n=8). Three days of the week, static stretching exercises are applied to the stretching group (GG) for eight weeks. After the completion of the eight-week stretching exercises, the same measurements were repeated in a similar order and the differences between the pre-test and the pre-test were assessed. In the analysis of the obtained data, the depending sampling t test was used in determining the differences within the group, the independent sampling t test was used in determining the differences between the groups (p<0.05). In the research findings, (GG) pre- and final test flexibility values (30,60±4,78cm; 33,90±3,14cm) and horizontal jump distances (206,38±19,93 cm; 210,25±19,47 cm) statically significant differences were detected (p<0,05). In the statistical analysis between the groups there was no significant difference (p>0,05). As a result, chronic thinning exercises in amateur footballers positively affect the jumping strength. In future research, mechanisms that form the physiological and metabolic basis of these effects can be investigated.
