“…In girls low, prenatal testosterone and high prenatal oestrogen is associated with large body size. 9 As was expected, in the present study we found a higher grip strength in men compared to women.…”

“…26 However, other studies have shown a positive correlation for 2D:4D to stature, mass, BMI, and waist circumference in girls, but the same correlation was not found for boys. 9 In the present study, we found a positive correlation between height and weight with 2D:4D ratio in men. A positive correlation was found between weight and 2D:4D ratio in women, but no correlation was seen between height and 2D:4D ratio in women.…”

Background: The ratio of the lengths of the index and the ring finger (2D:4D ratio) is generally different between men and women. This has often been used as an indicator of the levels of prenatal androgen exposure. It has hence been suggested to have a role in many gender differences including performance in sports. Men generally outperform women in most physical abilities. However, reports in various studies have been inconclusive, depending upon the physical ability tested. Hand Grip Strength (HGS) is a good measure of overall strength of an individual. Hence, we decided to determine the relationship between 2D:4D and HGS of both hands in men and women.Methods: Scanned images of both hands of young volunteers were analysed and the 2D:4D ratio calculated. HGS was measured and results correlated with 2D:4D.Results: 2D:4D ratio of men was significantly less than of women for the right (p<0.001) and the left hand (p<0.001). HGS of men was significantly greater than that of women for the right (p<0.0001) and for the left hand (p<0.0001). 2D:4D ratio in men showed a weak but significant positive correlation with HGS of right(p<0.05) and left hand(p<0.05). A weak but significant positive correlation was also seen for the left hand in females. However, 2D:4D ratios did not show any significant correlation with HGS for the right hand in women.Conclusions: We conclude that 2D:4D ratio is a measure of Hand Grip Strength in men, but is not a robust measure of HGS in women.

“…En el presente estudio las mujeres tuvieron un rendimiento superior en la fuerza de brazos en comparación con los hombres, lo que difiere a lo reportado en otra investigación, donde los niños poseían una fuerza de prensión manual significativamente mayor (22). El VO2 MAX fue mayor en los hombres, sin alcanzar significancia estadística (p ≥ 0,05).…”

Introduction: Low levels of moderate and vigorous physical activity are a factor of important behavioral risk in the obesity in children. Objective: The objective of this study was to determine the nutritional status and physical condition of students, by comparing the results obtained by gender, obesity, and physical performance. Material and methods: 578 students; 308 men of 11.22 ± 1.93 years and 270 women of 10.93 ± 1.92 years, participated in the investigation. Were evaluated; body mass index (BMI), percentage body fat (%FM), contour waist (CW), waist-to-height ratio (wtHR) and physical performance according to the test of the National Study of Physical Education of the Agency of Quality of Education of Chile. Results: The %FM was higher in women (p < 0.001). In the Test of abdominal and Navette performance was higher in men and in the test of fl exo-extensions of arm performance was higher in women (p < 0.05). Category of obese schoolchildren showed lower results in the test: abdominal, long jump, fl exo-extensions of arm and Navette (p < 0.001). The VO2 MAX was lower in the overweight subjects (p < 0.001). The students who need to improve 3 or 4 test presented more wtHR (p < 0.001) and %FM (p < 0.001). There is a negative association between the wtHR and the VO2 MAX (-0.543, p < 0.001).Conclusions: There exists a high predominance of excess weight and obesity, also it is appreciated a low physical performance associated with this condition. The students, who need to improve 3 or 4 test of physical condition, have a higher average of %FM and wtHR, this last variable is a powerful indicator of cardiovascular risk.

“…Although there are a good number of studies regarding 2D:4D in the literature, there are only a few studies concerning the correlation between 2D:4D ratio and physical fitness parameters in children and adolescents (Eghbali, 2016;Bilgiç et al, 2016;Ranson et al, 2015;Wang et al, 2016). Besides, it is a handicap that the results of all these studies are different from each other and it is assumed that the differences stem from the number of the subjects, their age, and frequency of doing physical exercise.…”

It is hypothesized that there is a correlation between the ratio of second hand finger to fourth hand finger (2D:4D) which is an indicator of prenatal testosterone and physical fitness and sportive performance The aim of this study was to determined correlation between the right hand finger ratio (2D:4D) and the parameters of anthropometric and physical fitness in male and female children aged between 10 and 12. Six hundred and seventy eight males whose age average was 0.49±1.32 and 592 females whose age average was 10.38 ± 1.48 participated in this study. In addition to taking the students' right hand 2D:4D, height, weight, triceps, subscapular, full arm and leg measurements, vertical jumping, standing long jump, flexibility, 20 m sprint, 10x5 agility, leg strength, right/left hand grip strength, 20 m shuttle run and balance tests were also performed. Statistically differences were found between anthropometric measurements apart from height and BMI, 2D:4D and physical fitness parameters in the males and females. A negative correlation between right hand 2D:4D and vertical jumping, standing long jump, 20 m sprint, 10x5 agility and right hand grip strength in the males. As for the females, although a negative correlation was detected between right hand 2D:4D and height, a positive correlation was found between the same variable and body fat ratio (p<0.05). It can be concluded that while a low 2D:4D ratio was correlated with static and explosive strength, speed and agility in the males, it was correlated with height and body fat ratio in the females.
