The Relationship

This article examines elite athletes’ understandings of the relationship between sport participation and health. Data are taken from interviews with 20 male and female athletes. Athletes’ assessments of the impact of sport on health and wellbeing include attributions of negative, positive, and, most often, mixed outcomes. In these elite athletes’ conceptualizations of health, injury and illness are subordinated to a view of health as capacity, and the primary frame of reference in which they consider capacity is their immediate competitive careers. Respondents’ accounts of efforts to manage the threats to their health that are posed by their sporting activity frequently convey a disembodied notion of the athletic body as an object to be managed.

The Relationship

The aim of this study was to investigate the relationship between 60m sprint results and reaction times in athletes who took part in the World Indoor Athletics Championships. The reaction times and 60m sprint results were compiled for 483 sprinters (253 male, 230 female) who performed 60m sprint event. Corresponding data were obtained from archives of the official website of the International Association of Athletics Federation (IAAF). The relationship between reaction time and 60m sprint results were calculated using Pearson correlation coefficient. Additionally, the Independent Samples T-Test was used to compare athletes’ reaction times and 60m sprint results. Positive moderate correlation was found between mean values of all 60m sprint results and reaction times, which were analyzed together in all categories (r=.436, p<0.01). Moreover, significant differences were also found between male and female finalists based on the 60m sprint times and reaction times respectively (t=-27.98, p<0.01; t=-3.26, p<0.01). As a result, it can be concluded that reaction time has great importance on 60 m performance. The best reaction time is related to the higher performance of 60m sprint in both male and female athletes. Moreover, this is also similar for round 1, semifinal and final categories. Coaches and athletes may consider improving reaction time to achieve better 60m performance.

The Relationship

Abstract Background: Inflammation appears to be an important component of concussion pathophysiology. However, its relationship to symptom burden is unclear. Therefore, the purpose of this study was to evaluate the relationship between symptoms and inflammatory biomarkers measured in the blood of male and female athletes following sport-related concussion (SRC). Results Forty athletes (n = 20 male, n = 20 female) from nine interuniversity sport teams at a single institution provided blood samples within one week of an SRC. Twenty inflammatory biomarkers were quantitated by immunoassay. The Sport Concussion Assessment Tool version 5 (SCAT-5) was used to evaluate symptoms. Partial least squares (PLS) analyses were used to evaluate the relationship(s) between biomarkers and symptoms. In males, a positive correlation between interferon (IFN)-g and symptom severity was observed following SRC. The relationship between IFN-g and symptoms was significant among all symptom clusters, with cognitive symptoms displaying the largest effect. In females, a significant negative relationship was observed between symptom severity and cytokines IFN-g, tumor necrosis factor (TNF)-a, and myeloperoxidase (MPO); a positive relationship was observed between symptom severity and MCP-4. Inflammatory mediators were significantly associated with all symptom clusters in females; the somatic symptom cluster displayed the largest effect. Conclusion: These results provide supportive evidence for a divergent role of inflammation on symptom burden in male and female athletes following SRC. Future investigations in SRC should be cognizant of the potentially sex-specific pathophysiology underlying symptom presentation.

The Relationship

Although several studies have reported a negative association between interscholastic athletic participation and delinquent behavior, research has failed to take account of the social psychological processes underlying the relationship. Consequently, the purpose of this study was to analyze the dynamic processes underlying the relationship between participation in interscholastic athletics and delinquent behavior. The study evaluated the relative contribution of 12 socio-psychological variables in the etiology of delinquent behavior among male and female athletes and nonathletes. Of the total sample of 1,693 high school students, 788 (442 males and 346 females) were classified as athletes. Overall, the results indicated that a similar pattern persists in the etiology of delinquent behavior among male and female athletes and nonathletes. Several differences were also found in the etiology of delinquent behavior among male athletes and nonathletes, female athletes and nonathletes, and male and female athletes.

Background: Questions remain as to whether core stability represents a single or more components, how to assess core stability, and if a relationship exists with athletic performance in different sport codes. Objectives: To investigate the relationship between core stability and athletic performance in female university athletes. Methods: Eighty-three female athletes (hockey, netball, running, soccer and tennis) participated in this quantitative, cross-sectional study. The isometric back extension (IBE), lateral flexion (LF) and abdominal flexion (AF) tests were used to measure core strength and endurance. The core stability grading system using a pressure biofeedback unit was applied to measure core neuromuscular control (NMC). Athletic performance was assessed using the 40 m sprint, T-test, vertical jump (VJ) and the medicine ball chest throw (MBCT). Correlations between the core stability tests and the athletic performance tests were determined, overall and separately by sport. The effect of core stability on athletic performance was analysed using ANCOVA. Results: Most correlations were weak (r=0.10–0.39), although a very strong correlation was found between LF (strength) and VJ (r=0.90). When considered separately, moderate correlations (r=0.40–0.69) were found between core strength, endurance and motor control with certain athletic performance tests in all five sport codes. In runners, strong correlations (r=0.70–0.89) occurred between AF (endurance) and VJ, and in tennis players between IBE (strength) and the sprint. Conclusion: Correlations were found between core stability and athletic performance, although most correlations were negligible or weak. Athletic performance in different sport codes is associated with different components of core stability.

OBJECTIVES The purpose of this study is to examine the relationship between lower extremity isokinetic muscle strength and dynamic balance ability of elite judo athletes and improve the efficient dynamic balance ability of athletes.METHODS A total of 26 male and female judo national candidates (13 males and 13 females) were participated. Isokinetic strength and dynamic balance in three consecutive areas of the lower limbs (knee, hip, waist) were measured. Multiple regression analysis step selection method was used to analyze the correlation between isokinetic strength measurement variables and dynamic balance ability. In addition, the results were analyzed by dividing the difference of fitness variables between male and female athletes and male and female athlete groups.RESULTS The male athlete group showed higher muscle strength in all areas of isokinetic strength (p <.01). Stability was statistically significantly higher (p <.05). There was interrelationship between the lower extremity isokinetic strength and the dynamic balance of the lower extremities in male and female athletes. The trunk flexion showed the highest correlation with the dynamic balance in the male athletes, and trunk flexion and hip extension in female athletes.CONCLUSIONS The trunk muscle strength showed the highest correlation with the dynamic balance ability in male and female athletes.

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.
