This research analyzes and has the purpose to study deeply about a physical fitness enhance which needs necessarily when we are appointed hereafter to the officer and do a platoon leader mission processing as school group officer candidates run parallel the university life. The particular about this, I put into operation soccer and 3-kilometer running to the candidate three times a week as an instruction program which uses the extracurricular work time. I measured 1500-meter running and push-up and sit-up with sophomore of before time and after time they join an organization and an army scholarship student like the general student to verify the effectiveness which the program have influence on physical fitness change. 1) 1.5-kilometer running training for a cardiorespiratory endurance presented meaningful time shortening to all R.O.T.C candidate was applied to instruction program. 2) The number of sit-up for abdominal muscular endurance measurement presented meaningful increment in number to all R.O.T.C candidate was applied to instruction program. 3) The number of push-up for an upper limbs muscular endurance measurement presented meaningful increment in number to all R.O.T.C candidate was applied to instruction program. An instruction program of R.O.T.C candidate is efficient for a cardiorespiratory endurance enhance and abdominal muscular endurance and an upper limbs muscular endurance. We examine the effectiveness to get closely in a physiology viewpoint through the R.O.T.C candidate's life of the inside of an irregular university life. Furthermore we are considered to have the meaning when we present the model of the instruction program to be developed hereafter through vertical and to be continuous research. Finally, it is true which the instruction program of R.O.T.C candidate contributes largely at the enhance of a cardiorespiratory endurance and a muscular endurance.
