The objectives of this study were to know: 1) The effect of anaerobic efforts on anaerobic ability and the significance of fatigue indicator on the level of anaerobic ability reduction for six repeated quick launches from a sample of female volleyball club players and from another equal sample of female volleyball practitioners. 2) The effect of anaerobic efforts on the concentration of lactate in the blood of the two samples after six repeated quick launches. Methodology: The researcher has used the RAST test as a measure for the anaerobic ability by running for 35m that is repeated for six times with 10sec resting interval for recovery between each run. At the end of the exercise, a blood sample is withdrawn to measure the lactate level. Results: The repeated anaerobic launches would lead to increase in the blood lactate concentrations and the reduction in the anaerobic ability has a positive relation with the fatigue indicator. Lastly, the objective of the increase in blood acidity is to reduce the continuation of activity. This is considered a preventive anabolic control to reduce the muscle contractions. Recommendations: The study has recommended further studies about the changes in muscular efforts and time needed to find out the excess in the lactates in blood of different ages and genders.
