Interval training is essential for players to acclimate their bodies to the demands of racing conditions, effectively managing race-pace and elevated lactate levels in the muscles. When compared to alternative training methods, interval training stands out by efficiently adapting to racing conditions while imposing minimal physiological strain. To excel on the football field, players must not only hone their skills but also master the diverse aspects of the game. Achieving professional competence requires dedicated practice of various drills to perfection. In addition to the diligence in drill work, the chosen training methodology significantly influences the quality of performance on the football field. This study attempts to estimate the influence of interval training and specific package of skill training on selected physiological and skill performance variables among school football players. To attain this purpose, 60 football players (boys) from various schools of Chennai District, Tamil Nadu, were randomly selected as subjects. The age of the boys ranged between 16 and 18 years. The boys were divided into four groups of equal number of 15 students each. Three of these groups were taken as three Experimental groups and the fourth group remained the Control group. Before the start of the training, the players were made to take a ‘Pre-test’ for vital capacity, dribbling and kicking. Each group was assigned a specific method of training: Isolated Interval Training was allotted to Experimental Group I; Isolated Specific Package of Skill Training was allotted to Experimental Group II; Combined Interval Training and Specific Package of Skill Training was allotted to Experimental Group III and the last  group  - Control  Group  - was  allotted  no  training  except  their daily  routine.  All three experimental groups were trained for a period twelve weeks. Post-Training tests were taken once this twelve-week training period was over. The data noted in this process was analyzed using the statistical tools of ANCOVA and Scheffe's Post hoc Test. The study affirmed that Experimental Group III, that was given Combined Interval training and Specific Package of Skill Training, showed significant improvement in physiological and skill performance variables when compared to other groups.
