Abstract
The aim of this study is to examine the association between physical fitness and 2D:4D finger ratio of high school students engaged actively in sports. 23 licensed male athletes and 23 sedentary (n=46) high school students participated in the study voluntarily. The participants age, body weight, body mass index, 2D:4D finger measurement values were recorded and 20 meter shuttle run, 30 meter sprint, sit and reach test, standing long jump and hand grip strength tests were applied on the participants. The data obtained were assessed in SPSS 21 program and the results were assessed at p˂0.05 significance level. While the average age of athletes was 15.82±1.11 years, the average age of sedentary group was 15.13±0.96 years. While statistically significant difference was found between sedentary and athlete groups in terms of VO2max, right and left hand grip strength and long jump average values (p<0.05), no statistically significant difference was found between speed and flexibility measurement results (p>0.05). When the 2D:4D averages of sedentary and athlete groups were compared, statistically significant difference was found between right hand averages (p<0.05). When right and left hand 2D:4D was compared, no statistically significant difference was found in sedentary group (p>0.05), while significant difference was found in athletes (p<0.05). Statistically significant difference was found between 2D:4D averages of both hands with all physical fitness parameters (p<0.05). In the present study, finger ratio of the groups were found to be associated with some motoric and functional dominance parameters.
Highlights
Physical fitness includes cardiorespiratory endurance, muscular endurance, muscular force, muscle strength, speed, flexibility, balance, reaction time and body composition (Özer, 2001)

Summary
Physical fitness includes cardiorespiratory endurance, muscular endurance, muscular force, muscle strength, speed, flexibility, balance, reaction time and body composition (Özer, 2001). For this reason, physical fitness cannot be assessed by a single test and consists of multiple distinct aspects such as balance, flexibility, speed of limb movement, sprinting speed, endurance and static, explosive, functional, and trunk strength as is evidenced by factor analyses e.g. Determination of physical fitness levels is possible especially through sportive achievement skills reaching the top level. For this reason, talents should be determined especially in early ages and suitable methods should be determined to find out talented athletes. It is possible to speak of the lack of talent identification practices especially for school children. A great number of researches have been conducted on this topic led by Manning (Manning et al, 1998); it is not yet possible to talk about a standard approach
