Based on the field motoric test battery, the characteristic outgoing system values will be obtained, and will directly describe level of realized abilities in each examinee in regard to speed and agility in specific motoric activities with or with no ball on the basketball court. Based on analysis of the force-time curve record, the characteristic outgoing values of the system will be obtained, and will directly describe the level of isometric neuromuscular function of leg extensors in each player at 100 and 180 ms level in the early phase of the contraction (200 ms). Despite the attention given to performance assessment by sports professionals and sports scientists, there are not enough researches examining the correlation of specific and special characteristics of force-time characteristics of leg extensor within the wide range of various battery of tests for motor skills assessment.īy measuring the isometric force developed by the leg extensors, the force-time curve can also be established, which will differ based on one's ability. If the test is more specific in regard to the sports branch, information obtained during the testings is more valid for evaluation the real fitness level. Purposefulness of the results on the athletes fitness level and the development level of tested physical properties, directly depend on applied test and its specific and measuring sensitivity. in the early phase of muscle contraction. Therefore, all the aspects of directed and specific fitness level should be focused on explosiveness increase (rate of force development – RFD), in the specific time interval in which the movement is realized, i.e. In competitive conditions top level athletes commonly realize movement in the maximal 300 ms time interval.

While performing fast movements of the extremities, it's impossible to achieve absolute values of maximal force at the level of full contractile potential of the engaged muscle. However, most of these studies focused on general characteristics of muscle force and explosiveness, i.e. From the aspect of theory and technology of the training, these types of researches are significant because, based on their results, the conclusions which would indicate the role of force and explosiveness in some sports activities could be gathered. There is a range of studies that have examined relationships between maximal isometric force and speed and agility. Due to this, adequate preparation of the leg extensors is extremely important, especially in sports such as basketball, which involve different jumping techniques, frequent changes of direction in the frontal and lateral planes, and in sports where muscle force and lower extremity strength have a significant influence on executing different technical and tactical demands. Both abilities require a rapid switch from eccentric to concentric muscle actions in the leg extensor muscles (stretch-shortening cycle of contraction – SSC).
Agility and speed are integral aspects of almost every defensive and offensive manoeuvre performed by basketball players during training and games. Testing motoric fitness levels of basketball players is an essential component in the evaluation of training programs and the assessment of players` progress during the season. the characteristic ground contact time during running in submaximal exertion regime, frequent changes of movement direction and vertical rebounds (from r=0.357 to r=0.612 with agility and from r=0.320 to r=0.468 with speed performance).Ĭonclusion - The practical implications of a moderate to strong and consistent correlation between neuromuscular function of the leg extensors and characteristics of performance tests might indicate that improvements in force-time characteristics in young basketball players, may result in significant improvements in speed and change of direction performances longitudinally. Results - Based on obtained results, among the measured leg extensors` force-time characteristics with the observed characteristics of performance tests, the best correlation was in maximal force parameters (from r=0.370 to r=0.610 with agility and from r=0.345 to r=0.574 with speed performance) and in rate of force development, measured in time interval of 180 ms, i.e. Material and Methods - Sixty young elite basketball players performed a standardized isometric leg press test in order to assess the characteristics of isometric force and 9 field tests in order to assess speed and agility performances. The aim of this research was to determine the relationship between the isometric force-time characteristics of the leg extensors and speed and agility performance.
