The purpose of this study was to investigate an effect of the complex − training on strength, power, and jump height in male university volleyball players during pre − competition season. Twenty three male university volleyball players were divided into the following three training groups; COMB （Combination − traing group, n ＝ 9）, COMP （Complex − training group, n ＝ 7）, and WT （Weight − training group, n ＝ 7）. The following training conditions were adopted for 2 or 3 times/week for 8 weeks in each training group. The COMB trained Squat − training（ SQ, 85%1RM） and depth − jump with rest（ 30 min）. The COMP trained SQ（ 85%1RM） and depth − jump without rest. The WT trained only SQ（ 85%1RM）. In order to evaluate the effect of training, the 1RM Squat, Squat Jump（ SJ）, Counter Movement Jump（ CMJ）, Drop Jump（ DJ）, and leg extension power were measured in pre − and post − training period.The main results were as follows：（ 1） Jump heights of SJ, CMJ, and DJ did not increase in all training groups.（ 2） The leg press power decreased in WT（ − 4.2%）.（ 3） The leg extension power increased in COMP（ +9.2%）. The results indicated that the complex − training did not affect on jump height, however, the leg press power was improved. In addition, high intensity SQ reduced the leg press power.
