Acl Injury Prevention Participation Among Collegiate Female Athletes, Natalie R. Bardwell

ELAIA

Background

A common injury for athletes is a tear in the anterior cruciate ligament, with a disproportionally higher rate of injury among female athletes than male athletes due to many anatomical and physiological differences. One of the proposed causes of increased injury is the difference in hormone levels during the phases of the menstrual cycle. Even though ACL injury prevention programs have been used to help reduce the number of injuries among athletes, it is not yet well known if changing hormone levels throughout the menstrual cycle is predictive of ACL injury risk among athletes that engage in injury prevention …

Posture Of Adolescent Male Handball Players Compared To Non-Athletes, Malgorzata Grabara

Baltic Journal of Health and Physical Activity

Background: The aim of the present study was to assess the posture and somatic parameters in adolescent male handball players compared to non-athletes and determine whether a relationship exists between the posture and the volume of training and/or its frequency. Material/Methods: Sixty-eight adolescent male handball players and sixty-nine non-athletes aged 15–18 were examined. The posture was evaluated by the moiré method. Results: Handball players exhibited smaller and less frequent asymmetries compared to the nonathletes. Statistically significant differences were found in the position of shoulder blades (p < 0.05) and pelvic alignment in the frontal (p < 0.001) and transverse (p < 0.05) planes. The spinal shape in the sagittal plane did not differentiate the training subjects from nonathletes. The study also revealed weak correlations between the training period and a deviation of the spinous processes (r = 0.25), a symmetry of the shoulder blades (r = 0.25), and an inclination angle of the thoracolumbar segment (r = -0.26). No correlations were observed between the training frequency and posture parameters. Conclusions: It can be concluded that despite the predominance of asymmetric elements, handball training does not negatively affect the posture in the frontal and transverse planes.

Macronutrients And Water – Do They Matter In The Context Of Cognitive Performance In Athletes?, Ewa Karpecka, Barbara Fraczek

Baltic Journal of Health and Physical Activity

Proper nutrition is a key factor in physical performance, but there are also indications of an impact of dietary components on the brain function. Therefore, the aim of the study was to assess the impact of macronutrients and water on cognitive performance. Assumptions of the Mediterranean diet correlate with better global cognition, episodic memory, lower risk of cognitive impairment and neurodegenerative diseases. In turn, a high-fat and high-sugar diet shows the opposite effect. Omega-3 fatty acids could be used as a preventive tool for cognitive decline, but there is still insufficient evidence if supplementation improves cognitive functions. The proper intake …

Positive Body Image Among Polish Elite Athletes, Aleksandra Budzisz, Krzysztof Sas-Nowosielski

Baltic Journal of Health and Physical Activity

Background: This study aimed to analyze factors differentiating body appreciation among Polish elite athletes. Material and Methods: Participants were athletes, both men and women (N=408), who completed questionnaire BAS-2. Results: In general, men had a better perception of their body than women (p<0.01). Higher appreciation of the body was visible among women sprinters, opposite to volleyball players (p <0.03). Indirect competition for women was connected to higher body appreciation (p<0.05). Gender and individual/team sport also significantly differentiated appreciation of the body (p<0.02). Furthermore, training frequency in a week differentiated body appreciation (p<0.03), as well as characteristic of sports performance [indoor sports, and higher in water sports (p<0.02)]. Conclusions: Results suggest that not only the common category of the sport type – aesthetic, technical, strength – differentiates the body image. Equally important for differences in body appreciation is also gender, sport discipline, and background of sport training: frequency per week, the character of competition (direct-indirect), individual/non-individual competition, or characteristic of sports performance.

The Relationship Between Scapular Endurance And Core Endurance In Elite Amputee Football Players, Gurkan Gunaydin

Baltic Journal of Health and Physical Activity

Background: Body structure constitutes a kinetic chain with thoracolumbar fascia and this chain may induce a relationship between scapular and spinal stabilizers. Amputee soccer players use crutches during the game and, considering that the crutch use may also activate different muscle groups, the possibility of the relationship between scapular and spinal stabilizers becomes important for organizing training programs. The aim of this study is to determine the relationship between scapular endurance and core endurance in elite amputee players. Material and methods: Fifteen male amputee national football team players took part in the study. The players’ scapular endurance was evaluated by …
