The purpose of this study was to investigate the effect of one-year specific aerobic gymnastics training on selected anthropometric and motor parameters in 6-11-year-old girls. 23 girls (average age in the beginning of the study was 8.04 ± 1.22 years) were involved in the study representing 2 different aerobic gymnastics sports clubs in Slovakia. The selected group completed their regular trainings and competitions for a period of one year. Measurements were taken in January 2019 and January 2020, in the middle of the preparatory period. Normality of distribution of the traits was examined using the Shapiro-Wilk test. Data were analyzed using Wilcoxon signed-rank test. Considering anthropometric parameters, there were significant changes (p≤0.01) in body height, body weight and BMI. Considering motor parameters, the mean values of straddle support hold and back extension endurance test increased significantly to the level of p≤0.05. The mean values of 4x10m shuttle run, standing long jump, modified push-ups, sit-ups in 60s increased significantly to the level of p≤0.01. No significant changes were observed in bent arm hang test or hanging knee tucks. On the other hand, the values of 1 leg stand with eyes closed and 2-min endurance shuttle run decreased insignificantly.
(1) Background: Joint and back pain are enormous and important clinical and public health problems that significantly affect people of all ages. Although the epidemiology of pain in the general population is well documented, less information is available in athletes. While in the general population joint and back pain have predominantly functional origin, in athletes, pain is a consequence of not only functional, but very often structural changes in the spine, joints, and related tissues. Depending on the sports specialization, character of the training activity, exercises, training load, and many other factors, athletes are exposed to various injuries accompanied by pain. (2) Aim: This study is aimed at evaluating the prevalence of spinal and limb injuries, and back pain and joint pain among athletes of various specializations. A questionnaire survey on back pain, quality of life, and physical activity will be used to collect data from Slovak athletes. The outcomes of the survey will be compared to a physically active group. This article presents a study protocol that aims to evaluate the relationship between back pain and injury prevalence in athletes of various specializations.
SummaryThe aim of the study was to determine the levels of lower limb explosive strength of girls in different sport specialization. The sample consisted of 24 girls in aerobic gymnastics (n = 12) and athletic (n = 12) aged 10 to 12 years. To assess the levels of girls’ lower limbs explosive strength, we administered the following tests: countermovement jump test, countermovement jump with free arms test, squat jump test, 10-seconds repetitive jumping test. Testing sessions took place in September 2019. To obtain data about the levels of lower limbs explosive strength, we recorded step height (cm) and duration of the flight phase (s). Data about the lower limbs explosive strength were collected using the Optogait system for optical detection. We applied basic statistical characteristics, namely Student’s t-test and multivariate linear regression. There were no significant differences between girls in aerobic gymnastics and athletics. We recorded better test results in the group of girl’s athletes in the countermovement jump, countermovement jump with free arms and squat jump. In the group of girl’s involved in aerobic gymnastics, we recorded better results in the 10-second repetitive vertical jumping and vertical jump strength. According to the collected data, we may conclude that the training process of the selected girls in terms of explosive strength development is significantly different. Girls involved in aerobic gymnastics showed a higher level of performance in the 10-second vertical jump, which results from the structure of sport specificity.
