Basketball is considered an intermittent high intensity sport that heavily stresses both aerobic and anaerobic metabolic systems. The purpose of this study was to investigate the effect of combined aerobic and resistance training on some selected physical fitness variables among Adet secondary and preparatory school male basketball players.The study employed Experimental research design. 22 male basketball players of Adetsecondary and preparatory school with the age of (EG=19.18±2.316, CG=18.73±0.1.679) were randomly assigned into 2 equal groups. Both the experimental group (EG, n=11) and control group (CG, n =11) participated in the regular basketball training, but only EG performed additional aerobic and resistance training for eight weeks, with 3 sessions per week, each lasting 40 to 60 minutes. Subjects were measured on aerobic fitness, 30m sprint time, vertical jump, , and agility on two occasions first before administration of the training as pre-test and after eight weeks ofthe training as post-test. The data collected from the study subject was analyzed using SPSS version 26 software by paired t-test with level of significant 0.05. The results showed that aerobic and resistance training significantly improved aerobic fitness, explosive power and agility performance in EG at (p<0.05). Similarly, sprint time was significantly reduced (p<0.05). Butno significant differences were found in all of the variables in CG (p>0.05). Based on this finding, it can be concluded that eight weeks aerobic and resistance training has positive effect on improvement of physical fitness variables of basketball players. Therefore, this type of training method is suggested to basketball players and coaches for improving physical fitness and performance skill.
