摘要：The ability to develop force as quickly as possible is called explosive muscle strength, and it is an important factor in many sports.Zatsiorsky (1995) defines explosive strength as “the ability to produce maximal force in minimal time”.Several authors have shown the positive correlation between sprints and jump performance.However, not many studies have observed the relation between sprints and isometric strength.24 junior sprinters participated in the study.Sprint tests, jump skills and isometric strength tests were carried out.Results indicated strong correlations between the results of sprint and jump tests.Correlations between jump height and isometric force were observed too.Correlations between isometric force and sprinting speed were observed only in 20 m sprints.No correlations between force and 100 m sprints were obtained.These findings indicate that the isometric force test is positively related to the first phase of sprint skills.
