The aim of the study is to examine the effect of the exercise log on the health-related physical fitness parameters of secondary school students. The study group of the research consists of 338 students studying at the 5th, 6th and 7th grade levels. The ages of the students range from 10 to 12. Before the study, classes were assigned as control and experimental groups, each class level being equal and unbiased. In the study, both control and experimental groups were taught physical education and sports lessons with the same course content for 12 weeks, and they were asked to do moderate and high-intensity exercise for 60 minutes at least three days a week outside of school. While the experimental group regularly recorded the exercises they did during the implementation process on the exercise log, the control group did not. In the study, students were tested twice with measurement tools before and after the application. In the study, push-ups and sit-ups were used to determine the muscular strength and endurance parameters of the students, one of the health-related physical fitness (HPF) parameters, the single-leg sit and reach flexibility test to determine their flexibility, and the height and body weight measurements were used to determine their body composition (BC). Obtained data were analyzed with factorial ANOVA test for repeated measurements. The findings of the study showed that the HPF post-test scores of the control and experimental groups were significantly higher than the pre-test scores. In addition, it was determined that the upper body muscle strength and endurance, lower body muscle strength and endurance and flexibility performance of the experimental group were significantly higher than the control group. As a result of the research, it can be said that the exercise chart, which is used as a self-monitoring and evaluation tool, is effective in improving HPF parameters.
