Purpose. - The aim of this study was to examine Optojump system efficiency to analyse lower limbs explosive strength. Methods and results. - Twenty untrained subjects were randomly assigned to 2 groups: either an experimental group (N = 10) or a control group (N = 10). They performed vertical jumps using different techniques and sprints. Reproducibility of jumps and sprint, evaluated by Optojump system, was appreciated after correlation analysis. The experimental group took part in a plyometric training for six weeks. Jumps and sprints showed an excellent reproducibility (mean coefficiant of variation = 3.6%). Plyometric training increased (P < 0.001) counter movement jump (+ 19.6%), counter movement jump free arms (+14%) and drop jump (+27.9%) performances. Conclusion. - This study demonstrated the accuracy and validity of the Optojump system to analyse lower limbs explosive strength. (c) 2005 Elsevier SAS. Tous droits reserves. [less ▲]

BACKGROUND: Spike effectiveness represents a determining element in volleyball. To compete at a high level, the player must, in particular, produce a spike characterized by a high ball velocity. HYPOTHESIS: Some muscular and physical features could influence ball velocity during the volleyball spike. STUDY DESIGN: Descriptive laboratory study. METHODS: A total of 19 male volleyball players from the 2 highest Belgian national divisions underwent an isokinetic assessment of the dominant shoulder and elbow. Ball velocity performance (radar gun) during a spike test, morphological feature, and jump capacity (ergo jump) of the player were measured. We tested the relationship between the isokinetic parameters or physical features and field performances represented by spike velocity. We also compared first-division and second-division player data. RESULTS: Spike velocity correlated significantly with strength performance of the dominant shoulder (internal rotators) and of the dominant elbow (flexors and extensors) in the concentric mode. Negative correlations were established with the concentric external rotator on internal rotator ratio at 400 deg/s and with the mixed ratio (external rotator at 60 deg/s in the eccentric mode on internal rotator at 240 deg/s in the concentric mode). Positive correlations appeared with both the volleyball players' jump capacity and body mass index. First-division players differed from second-division players by higher ball velocity and increased jump capacity. CONCLUSION: Some specific strength and physical characteristics correlated significantly with spike performance in high-level volleyball practice. CLINICAL RELEVANCE: Our results could provide useful information for training management and propose some reflections on injury prevention. [less ▲]

Introduction. - This study explored concentric and eccentric profile of knee musculature in a jumpers population. Relationships between isokinetic assessment and field tests performances have also been explored. Materials. - Jumpers population presented higher knee flexors performances in concentric and eccentric mode and superior knee extensors strength in eccentric. Significant correlations between isokinetics and field tests results were exclusively observed with athletes quadriceps performances. A very high correlation (r = 0.93) was found between the second bound relative performance of the ten multijumps test and eccentric quadriceps relative peak torque. Conclusion. - Jumpers training may favour a specific muscular development. The knee extensors eccentric strength may be a major factor in the athletic performance. (c) 2005 Elsevier SAS.

The main objective of this study was to explore the mechanical and electrical output of thigh muscles derived from a range of motion (RoM) of 90 degrees (0-90 degrees flexion, LR) and the three successive RoMs: 0-30 degrees (SR1), 30-60 degrees (SR2) and 60-90 degrees (SR3). Thirteen men took part in the study. In view of the torque-velocity relationship and in order to render the test conditions as equivalent as possible, LR was tested at 90 degrees /s while the corresponding velocity for all SRs was 30 degrees /s. The findings indicated very good agreement between LR and SR2 in terms of absolute strength (particularly the concentric), within muscle eccentric to concentric strength ratios, between muscles (agonist to antagonist) strength ratios and the normalized IEMG (expressed in muV/Nm). An agreement was also noted between the mean eccentric peak torque of the knee flexors at LR and SR1 and between the mean eccentric peak torque of the knee extensors at LR and SR3. However, in general there was a lesser agreement between LR and SR1 or SR3. It is suggested that testing thigh muscles in the middle sector of knee motion (SR2) yields strength and EMG data that are close and well correlated with those derived from testing the knee along the commonly used (0-90 degrees ) RoM.
