Does the Intron 7 Gene Variant (rs4253778) Influence Performance in Power/Strength-Oriented Athletes? A Case-Control Replication Study in Three Cohorts of European Gymnasts. | LitMetric

AI Article Synopsis

Article Abstract

Athletic ability is influenced by several exogenous and endogenous factors including genetic component. Hundreds of gene variants have been proposed as potential genetic markers associated with fitness-related phenotypes as well as elite-level athletic performance. Among others, variants within the PPARA gene that code for the peroxisome proliferator activated receptor α are of potential interest. The main goal of the present study was to determine PPARA (G/C, rs4253778) genotype distribution among a group of Polish, Lithuanian and Italian international level male gymnasts and to compare our findings with those of previous research on the frequency of the PPARA intron 7 C allele/CC genotype in power/strength-oriented athletes. A total of 464 male subjects (147 gymnasts and 317 controls) from Poland (n = 203), Italy (n = 146) and Lithuania (n = 107) participated in the study. No statistically significant differences were found in any of the analyzed cohorts. However, a significantly higher frequency of the CC genotype of the PPARA rs4253778 polymorphism was observed when all gymnasts were pooled and compared with pooled control using a recessive model of inheritance (OR = 3.33, 95% CI = 1.18-10, p = 0.022). It is important to know that we investigated a relatively small sample of male European gymnasts and our results are limited only to male participants. Thus, it is necessary to validate our results in larger cohorts of athletes of different ethnicities and also in female gymnasts to find out whether there is a gender effect.

The human lifespan is influenced by various factors, with physical activity being a significant contributor. Despite the clear benefit of exercise on health and longevity, the association between different types of sports and lifespan is yet to be considered. Accordingly, we aimed to study this association in a large international cohort of former athletes using a robust linear regression model.

This study investigates individual performance adaptations on 2 years of training between European Aerobics Championships. An elite, 22-year-old aerobic gymnast performed postural coordination test, Y-Balance test, squat and countermovement jumps, 60 s test of repeated jumps, an isokinetic leg muscle strength test, and the Wingate test. Postural stability and flexibility improved in terms of increased distance achieved in the Y-Balance test in the anterior (by 6.

Introduction: Subacromial impingement syndrome is a common pathology that leads to a persistent decrease in the functioning of the affected limb and, as a consequence, a decrease in the quality of life and work ability of patients. According to various authors, the study of the effectiveness of treatment and rehabilitation of this pathology is quite widely presented in the literature: surgical, including arthroscopic operations, rehabilitation using various factors of physical therapy, manual and other practices. However, the issue of assessing the effectiveness of movement therapy, both alone and in combination with other therapeutic methods, remains relevant.

Impact of Physical Activity on Autonomy and Quality of Life in Individuals with Down Syndrome: A Systematic Review.

Down syndrome (DS) is the most common genetic alteration in humans, resulting from the trisomy of chromosome 21. Individuals with DS are characterized by physical traits and limitations related to intellectual functioning and the development of motor skills. People with DS tend to have lower levels of physical activity (PA) than the general population, despite its benefits for health and quality of life, which could be caused by barriers such as the lack of adapted programs or knowledge on how to adapt them.

Purpose: The aim of this study was to investigate internal Achilles tendon (AT) displacement, AT shear wave velocity (SWV), and triceps surae (TS) muscle shear modulus in athletes.

Methods: Internal AT displacement was assessed using ultrasound during isometric contraction. Shear wave elastography was used to assess AT SWV (m × s) at rest and TS muscle shear modulus (kPa) during passive ankle dorsiflexion.
