The aim of this study is to investigate the aerobic and anaerobic powers of students in different grades of the schools and describe the correlation between these powers. Upon the written approval of Samsun National Education Management, this study was carried out with the voluntary participation of 120 females and 120 males aged 11-16, who were healthy and were not active in sports. The total number of the subjects participating in the study was 240. The aerobic and anaerobic power tests of the subjects were determined through Cooper and Wingate tests respectively. All statistical calculations were evaluated through the SPSS 13 package program. The relationship between the aerobic and anaerobic powers of male and female students aged 11, 12, 13, 14, 15, and 16 was examined through Spearman correlation test. The correlations between anaerobic and aerobic powers of the subjects were as follows: 0.06 for 11-year-olds, 0.43 for 12-year-olds, 0.21 for 13-year-olds, 0.24 for 14-year-olds, 0.27 for 15-year-olds, and 0.12 for 16-year-olds in females while 0.13 for 11-year-olds, 0.01 for 12-year-olds, 0.13 for 13-year-olds, 0.43 for 14-year-olds, 0.23 for 15-year-olds, and 0.56 for 16-year-olds in males. In conclusion, no meaningful correlations between the anaerobic and aerobic powers of subjects were found.
