Associations between bio-motor ability, endocrine markers and hand-specific anthropometrics in elite female futsal players: a pilot study

Abstract

Background The second-to-fourth digit ratio (2D:4D) has been calculated for individual athletes and sports, but it has not been investigated in futsal performance. Therefore, the aim of this study was to investigate any relationships between 2D:4D of the dominant and non-dominant hands and physical capacity performances, selected functional variables and hormone concentrations in elite female futsal players. Methods Twenty-four elite female futsal players were measured for 2D:4D in the dominant (2D:4DD) and non-dominant (2D:4DND) hand. The futsal specific performance test (FSPT), hand-grip strength (HGS) and aerobic power were also assessed. In addition, selected circulatory hormones were measured (estradiol, cortisol, growth hormone and insulin like growth factor-1). Pearson’s correlation test was used to identify correlational relationships. Results Total test-time and performance time (total time + penalty time) for the FSPT showed a significant correlation with 2D:4DD (r = 0.53, p = 0.005 and r = 0.55, p = 0.003, respectively). HGSND also displayed a significant correlation with the 2D:4DD (r = 0.59, p = 0.002). Aerobic power and time spent running on the treadmill also showed a significant relationship with 2D:4DND (both, r = 0.54, p = 0.006). Cortisol showed a significant correlation with 2D:4DD (− 0.58, p = 0.003) and 2D:4DND(− 0.52, p = 0.008). Conclusions The measurement of 2D:4D ratio could be an important factor in determining potential performance attributes and talent identification of elite female futsal players. Further studies are needed in this area to further examine the results presented here.

Association of 2D:4D finger length ratio of People Working in different professions with personality traits

“…Tatar et al, found in their study that there is a connection between FFPI and finger length. In line with these studies, we think that looking at finger length ratio will provide information about personality and profession [ 20 , 39 , 39 , 43 , 44 , 44 ]. In the light of the studies, we reached out to individuals in different professional groups and investigated whether or not their finger length ratios were correlated with FFPI and CAAS test results.…”

Comparison of circulation parameters and some motoric adaptations of futsal athletes and sedentaries

“…A football player or futsal athlete has to be fast while running, changing direction, attacking and defending throughout the match. Power is an important element, especially in sports that require speed and explosiveness (Farhani et al, 2022).…”

“…Futsal is a team sport that includes intermittent and high-intensity physical activities played with unlimited substitutions in a narrow 20x40m field. The fact that the futsal ball has a less bouncing feature forces futsal players to improve their ability to play faster by keeping the ball in play all the time (Farhani et al, 2022). This situation requires players to have the ability to make quick decisions under pressure in attack and defense, to be more mobile and faster, and to change direction suddenly (Dogramaci et al, 2011).…”

Monitoring Readiness to Train and Perform in Female Football: Current Evidence and Recommendations for Practitioners

“…Testosterone, on the other hand, is important for muscle growth and recovery and its level monitoring can help pinpoint any imbalances that may affect readiness and performance. 55,56 Specifically, testosterone concentration (and some other sex hormones) is one of the primary determinant of sex-based differences in athletic and sports performance. 57 Therefore, hormone tests, especially those related to the menstrual cycle, are also critical for female players, specifically, tracking hormones such as estrogen and progesterone helps understand the potential impact of menstrual cycle on performance and recovery (although more high-quality evidence is needed to show what affect performance parameters).…”
