The purpose of the present study is to investigate the effects of jogging in the early morning and high protein breakfast on the various physiological function. Subjects of this study were 5 non-athletes students (19-24 years old). 3 subjects engaged in this experiment for 13 weeks, one for 7 weeks, and one for 4 weeks.
　Frequency of jogging were 3-4.5 times a week. Sublingual temperature rose up to about 37℃ immediately after jogging, and heart rates at that time were 120-130 beats/min.
　The results were as follows:
　1) Concentration measured by "Brain Excitement Meter" and flicker frequency increased significantly 23.3% (p<0.01) and 4.4% (p<0.05) respectively at the 7th week following the continuation of jogging in early morning and of high protein breakfast. Values of these concentration items of 3 subjects who carried out jogging until the 13th week increased significantly 25.5% (p<0.01) and 15.2% (p<0.05) respectively.
　2) Back strength increased gradually until the 7th week (9.4%), but it was not statistically significant. It's mean value of 3 subjects who carried out jogging until the 13th week increased significantly 22.0% (p<0.05). Leg extension strength increased gradually, but it was not statistically significant (mean value at the 7th week was 8.4% and at the 13th week was 16.1%)
　3) There was little effects on maximum anaerobic power by bicycle ergometer. Effect on maximum speed was found in 4 subjects, but it was not statistically significant.
　4) Effect on shuttle run was found in 4 subjects, but it's increment was small. Effect on stepping in chair was not found utterly.
　From these results, it was confirmed that continuation of jogging in early morning and of high protein breakfast enhanced the function of central nervous system in the morning, and increased the strength of legs and back.
