The Relationship

Abstract The relationship between anthropometric and physical characteristics of female handball players and throwing velocity is considered an important factor in handball performance. The aim of this study was to examine key differences in anthropometric and fitness characteristics between top elite and elite female players competing in the first Spanish handball league. A total of 89 players from the first Spanish handball league were divided into two groups, top elite (38) and elite (51) players, and assessed for anthropometric and fitness characteristics (throwing velocity, vertical jump and hand grip strength). A Student’s t-test was used to determine whether a statistically significant difference between the two different levels of play occurred. Significant differences were found in age, body height, body mass, arm span, muscle mass, different girths (tensed and flexed arm, forearm, wrist, ankle), dominant hand width and length, different breadths (biacromial, bitrochanteric, bistyloid breadth and biepicondylar humerus) and fitness characteristics (hand grip strength and throwing velocity for different positions). Top elite players compared to elite players showed differences in anthropometric characteristics which were mainly located in the upper limbs and mostly were nonmodifiable aspects by training. Furthermore, the best players were able to maintain a high throwing velocity in different tactical situations.

The index finger and the 4th finger ratio (2D:4D) is the indicator of the prenatal testosterone. The aim of this study is to investigate the relationship between 2D:4D, hand preference and hand grip strength in swimmers. A total of 80 elite swimmers, participated in the study. Height, body weight, body mass index (BMI), hand 2D:4D finger measurements and hand grip strength tests were performed for athletes. The hand preference was determined by the Oldfield questionnaire and it was evaluated according to the Geschwind score. The data were recorded in the SPSS 20 program and p<0.05 was considered as statistically significant. It was found that in both men and women, a negative correlation was found between right and left hand 2D:4D and both dominant (DHGS) and non-dominant hand grip strength (NDHGS) values. It was found that men had lower 2D:4D ratio than women. For both right and left handed, there was a statistically significant difference between the right and left hand 2D:4D ratios in both men and women (p<0.05) and the dominant hand (DH) 2D:4D ratios were found to be lower than non-dominant hand (NDH) 2D:4D ratios in both men and women (p<0.05)  It can be said that the 2D:4D ratios may be the effect of determining the hand preference, the grip strength and therefore the strength.

Significant Difference

The aim of this research was to define differences in functional and mechanical characteristics of isometric hand grip (HG) strength between young female handball players and the CG comprised of physically active girls with no experience in sport. 70 individuals participated in the research, 36 of whom were the best young female handball players (of cadet and junior categories) while 34 girls comprised the CG. The results obtained show that the young female handball players who took part in the tests achieved Fmax at the levels from 306.4±40.8 to 335.5±47.0 N and RFDmax at the levels ranging from 1918.1±366.8 to 2174.4±382.1 N/s for the non-dominant and dominant hand. When these results are compared to the ones achieved by the CG it is clear that the young female handball players had a statistically significant higher level of the maximum HG force of both arms as well as the higher level of maximum explosiveness. There was no statistically significant difference between the groups regarding all the indexes of dimorphism (ID) as well as the values of the time needed for achieving the maximum intensity of muscle excitation (tRFDmax). Therefore, it can be concluded that the handball players who underwent the testing procedures showed positive adaptation from the aspect of the mechanical characteristics of hand grip strength, which can most likely be ascribed to the phenomenon of biological adaptation to the training stimuli characteristic for handball. However, the same influence was not detected from the aspect of functional characteristics, more precisely, dimorphism.

The Relationship

Lateralization, which is also known as hand preference, and 2D:4D finger ratio is a sign of prenatal testosterone and known to be associated with strength. The aim of this study is to investigate the relationship between 2D: 4D, lateralization and hand grip strength in relation to hand and forearm that are thought to be effective in handball in elite handball players. 67 female and 67 male elite players participated in this study. The height, weight, body-mass index and hand preference of these athletes have been identified and 2D: 4D finger measurements and hand grip strength tests were performed. When identifying the preferences regarding lateralization, the hand distribution preference was determined by the Oldfield questionnaire and evaluated using the Geschwind score. After photocopy images of the two hands of the athletes were taken, their finger lengths were measured Hand grip strength was determined by a Jamar hydraulic dynamometer. Strong correlation was found especially between 2D: 4D and dominant hand grip strength in male and female elite handball players. The ratio of left-handedness due to the positions of players during the game among male and female athletes has been found to be higher than that of the general population. With regard to gender, 2D: 4D was found to be lower in males than females but hand grip was found to be higher in males than females. Besides, a significant correlation between height and BMI with 2D:4D, sport age, height, body weight and hand grip strength was found. This study emphasizes the importance of 2D: 4D, handgrip strength and hand preference in handball.

Functional Measure

Hand grip strength (HGS) is a useful functional measure of the integrity of the upper extremities, however, many studies have examined it from selected positions (i.e., supine, sitting, standing), with no emphasis on other derived positions that are used in clinical setting. This study’s objective was to evaluate HGS in different body positions that are used in clinical setting by using a standard protocol. The study sample was a convenience sample of 40 healthy male participants with no history of psychiatric, neurological, or upper extremity orthopedic dysfunction. Grip strength in the dominant hand was measured with a Jamar Plus[Formula: see text] digital hand dynamometer in five positions: Supine, prone, side-lying, sitting, and standing. The HGS value in prone position was significantly lower than in standing position ([Formula: see text]) and sitting position ([Formula: see text]). However, no statistically significant difference was found in HGS among the supine, prone, and side-lying positions. Grip strength was moderately correlated with age ([Formula: see text]). This study provides useful evaluation for grip strength in different positions. In identical upper extremity positions, grip strength varies between different body positions. Grip strength is equivalent when tested from the supine, side-lying, or prone positions, thus the position can be adjusted according to the patient’s condition. Finally, age is an important determinant of hand grip evaluation, particularly when standing position is used.

Distal Interphalangeal

Background: Pain of the hand distal interphalangeal joints may result from trauma, osteoarthritis or inflammatory arthritis. When symptoms are not controlled by non-operative means, surgical arthrodesis may be performed, resulting in complete stiffness of the joint and possible weakening of grip strength. This study aims to quantify the effect of a stiff ring finger distal interphalangeal joint on overall grip strength. Methods: One hundred participants were screened to exclude upper limb pathology. A Jamar dynamometer was used to assess overall hand grip strength. A splint was used to prevent distal interphalangeal joint flexion, thus replicating a fused distal interphalangeal joint. Participants were tested with and without the splint and the results compared. The mean of three grip strength tests was taken. Results: The participants included 55 females. Mean age was 31 (18–60 years). 76 participants had a reduction in grip strength with splinting, with a significant difference seen (p < 0.05) on Wilcoxon signed rank test. The median reduction in grip strength with splinting was 1.67 kg. However only 10 participants (10%) had a grip strength loss of greater than 6.5 kg, which is the minimal clinically important difference. Conclusions: This study found a significant loss in overall hand grip strength when the ring finger distal interphalangeal joint was stiffened. However, despite this significant change, only 10 (10%) participants experienced a reduction of greater than 6.5 kg. This is the level of weakness felt to be required to reduce function. Thus our results suggest that 90% of patients with a stiff ring finger distal interphalangeal joint are unlikely to have a clinically identifiable functional reduction in grip strength as a result.

Grip strength is an important measure used to monitor the progression of a condition, and to evaluate outcomes of treatment. We assessed how various physical and social factors predict normal grip strength in an adult Malaysian population of mixed Asian ethnicity (254 men, 246 women). Grip strength was recorded using the Jamar dynamometer. The mean grip strength for the dominant hand was 29.8 kg for men and 17.6 kg for women. Multiple regression analysis demonstrated that the dominant hand grip strength was positively associated with height and body mass index, and negatively associated with age for both sexes. Dominant hand grip strength was related to work status for men ( p < 0.05) but not for women. However, there was no difference in grip strength among ethnic groups.

Introduction: An individual’s overall muscle strength is commonly assessed by a power grip measurement, a reliable indicator of functional capacity and physical condition. The development of muscle parallels the changes of body composition during growth. Aim of this study is to examine the correlationship between hand grip strength and anthropometric. Methods: This cross-sectional study involved 76 male students of Dhammasavana School, aged between 12 – 16 years old, North Jakarta. Hand grip strength was examined using a digital dynamometer on the dominant side. Statistical analysis was computed using SPSS ver. 15.0 program with Spearman correlations test. Significance was set at p<0.05. Results: Dominant hand grip strength was found to have significant (p<0.05 - 0.001) positive correlation with height (r=0.612), lower arm muscle-and-bone cross-sectional circumference and area (CSA) (r=0.553 and r=0.553 respectively), hand length (r=0.548), forearm length (r=0.540), age (r=0.520), weight (r=0.416), and forearm girth (r=0.376). Conclusion: No significant correlation between grip strength and body mass index was found. Positive correlations between the variables mentioned above conclude that the higher the value of the anthropometric measurements, the greater the strength generated in a power grip.
