“…When right hand 2D:4D and left hand 2D:4D average values were compared in the sedentary group, no statistically significant difference was found, while significant difference was found in athletes. Statistically significant difference was found between right and left hand 2D:4D ratios in elite male swimmers in Acar and Eler (2018)'s study and in male taekwondo athletes in Kim [23]'s study (p<0.05). In the present study and in Kim (2016)'s study, left hand 2D:4D ratios are lower when compared with right hand 2D:4D ratios.…”

“…Hill et al, (2012), (n=41) found no significant relation between maximal oxygen uptake and right or left 2D:4D. Acar and Eler (2018), found negative correlation between right and left hand 2D:4D and both dominant and non-dominant hand grip strength of elite men swimmers. , also found negative correlation between right and left hand 2D:4D and both dominant and non-dominant hand grip strength of men elite handball players.…”

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 VO 2 max, 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.

“…Interestingly, the methodology of "2D: 4D" was also used by other specialists [46,[48][49][50][51][52]. Kamińska and Szymańska-Parkieta [53] studied a large group of schoolgirls of 13 years old and found that in physically more developed girls, the proportions of the fingers were close to male.…”

Background and Study Aim. To develop and justify the criteria for morphogenetic markers of speed-power abilities of athletes and the main directions of individualization of the process of their preparation, taking into account the characteristics of the female body. Material and Methods. Using the “2D: 4D” determination methodology, finger proportions were analysed for 126 qualified athletes specializing in speed-strength types (sprinting and hurdling, jumping, shot-putting) of different ages (from 17 to 25 years old). For 13 weeks, eight qualified short-distance student runners were regularly tested using computer strain gauge equipment: 5 masculine and 3 feminine types. The tensodynamograms of the manifestation of the strength of muscle groups carrying the main load in the structure of the sprint run were recorded and processed. Results. It was found that 78% of the examined athletes observed finger proportions close to the "male" proportions. This may indicate their certain masculinization. The technique used for this can be an informative and simple marker to predict a genetic predisposition to the ability of effective performance of speed-power work. It was determined that the same amount of power load causes masculine athletes, runners for short distances, a more significant deployment of long-term adaptation restructuring of masculine athletes, runners for short distances, compared with athletes of a different gender identity. Conclusions. Criteria for the prognostic assessment of speed-power abilities of athletes based on simple biological markers for testing and identification, like finger proportions (2D: 4D), have been developed. For athletes of high qualification who have a gender identity similar to men and a masculine somatotype, it is possible to use adapted male techniques for training.

“…14 Sportif performans ile sağ-sol 2D:4D arasında, yalnızca sağ 2D:4D arasında ilişki olduğunu, ne sağ ne sol 2D:4D arasında ilişkinin olmadığını ya da yalnızca sağ 2D:4D ile sol 2D:4D arasındaki ilişkiyi inceleyen birçok çalışma bulunduğu bilinmektedir. 15,16 Hönekopp ve ark. yaptıkları çalışmada 2D:4D ile performans arasında kadınlarda sol elde, erkeklerde ise sağ elde düşük ilişki tespit edilmiş, diğer bir çalışmada ise sadece erkeklerde sol 2D:4D arasında, Fink ve ark., erkeklerde 2D:4D ve el kavrama kuvveti arasında; Eler ve Eler, erkeklerde sağ-sol 2D:4D, kadınlarda yalnızca sol 2D:4D arasında; Acar ve Eler erkek ve kadınlarda negatif yönlü ilişki olduğunu ifade etmişlerdir.…”

Hentbol oyunu, savunma ve hücum organizasyonlarından oluşan yoğun efor gerektiren bir spor branşıdır. Bu organizasyonlar uygulanırken; yürüme, paslaşma, sıçrama, şut, blok, kısa mesafe hızlı koşular gibi değişken aktiviteler içerir. 1 Ayrıca hentbolda kas kuvveti, güç ve teknik-taktik gibi yetenekler müsabakalarda net avantaj sağlayan faktörlerdir. 1 Marques (2009), hentbolu sürekli patlayıcı sprintler, sıçramalar, yön değişiklikleri, paslaşma gerektiren ve bunları yaparken vücut teması
