The Effect of Detraining After A Series of Functional Training on Some of Skill and Physical Fitness Factors in girls Volleyball Players

Training adaptations vary due to the training programs. Maintenance of the adaptations obtained through training is a great concern of researchers and experts in sports physiology. Therefore, the aim of this study was to investigate the effect of detraining on skill and physical fitness of female teenage volleyball players, following a period of functional training. 23 female teenage volleyball players were selected from Zarghan city. Then, they were randomly divided into two groups of control (n=10, age: 13± 0.66 years old, height: 160.10±0.06 cm, weight: 56.25±11.2 kg) and experimental (n=13, age: 13.53±0.66, height: 163.45±6.8 cm, weight: 59.32±10.07). First, the subjects did functional training, for four weeks, with an incremental intensity. After four weeks of training, they passed the two-week detraining period. The variables included repeated-effort test (RET), professional agility, Broad jump and proprioception, which were measured in the field, before and after training and after the detraining period. The results of the Mixed ANOVA showed a significant increase in RET, professional agility time, altitude jump and Proprioception, after one month of functional training (p <0.05). After a period of detraining, there was a decrease in all variables, which was not statistically insignificant (p ≥0.05). It seems that one month of functional training can improve and prevent the effect of detraining on skill and physical fitness of female teenage volleyball players.
