PURPOSE The purpose of this investigation was to determine the reliability of the 30-15 Intermittent Fitness Test (30-15(IFT)) in semiprofessional soccer players. METHODS Fourteen male semiprofessional soccer players performed the 30-1(IFT) on 2 occasions separated by 7 d. Reliability was assessed by intraclass correlation coefficient (ICC), typical error(More)
Various thresholds have been used to identify the onset of contraction during isometric mid-thigh pull (IMTP) however, no agreed onset threshold exists for this assessment. The purpose of this study was to compare relative body weight (BW) and arbitrary onset thresholds to a criterion onset threshold 5 SD of BW for IMTP force-time variables; force at each(More)
PURPOSE Skeletal-muscle function can be evaluated using force-times curves generated via the isometric midthigh pull (IMTP). Various sampling frequencies (500-1000 Hz) have been used for IMTP assessments; however, no research has investigated the influence of sampling frequency on IMTP kinetics. Therefore, the purpose of this study was to investigate the(More)
PURPOSE The purpose of this study was to investigate the within-session reliability of bilateral and unilateral stance isometric mid-thigh pull (IMTP) force-time characteristics including peak force (PF), relative PF and impulse at time bands (0-100, 0-200, 0-250 and 0-300 ms); and to compare isometric force-time characteristics between right and left and(More)
Mechanical variables during change of directions for example braking and propulsive forces, impulses and ground contact times (GCT) have been identified as determinants of faster change of direction speed (CODS) performance. The purpose of this study was to investigate the mechanical determinants of 180° CODS performance with mechanical characteristic(More)
