Nutritional habits among high-performance endurance athletes.

Background And Objective: For athletes, the main purpose of nutrition is to ensure the compensation of increased energy consumption and the need for nutrients in the athlete's body, thereby enabling maximum adaptation to physical loads. The aim of this study was to determine the habits of highly trained endurance athletes depending on sports type, sex and age in order to improve the planning and management of the training of athletes using targeted measures.

Materials And Methods: In 2009-2012, the dietary habits of 146 endurance athletes were analyzed.

Organic food consumption by athletes in Lithuania.

Background: With environmental pollution increasing, interest in organic farming and organic foodstuffs has been growing all over the world. Data on organic food consumption by Lithuanian athletes is not yet available. This lack of data determined the aim of this study: to identify the particulars of organic foodstuff consumption among athletes.

AMPD1 rs17602729 is associated with physical performance of sprint and power in elite Lithuanian athletes.

Background: The C34T genetic polymorphism (rs17602729) in the AMPD1 gene, encoding the skeletal muscle-specific isoform of adenosine monophosphate deaminase (AMPD1), is a common polymorphism among Caucasians that can impair exercise capacity. The aim of the present study was twofold: (1) to determine the C34T AMPD1 allele/genotype frequency distributions in Lithuanian athletes (n = 204, stratified into three groups: endurance, sprint/power and mixed) and compare them with the allele/genotype frequency distributions in randomly selected healthy Lithuanian non-athletes (n = 260) and (2) to compare common anthropometric measurements and physical performance phenotypes between the three groups of athletes depending on their AMPD1 genotype.

Results: The results of our study indicate that the frequency of the AMPD1 TT genotype was 2.

Variation in the ACE, PPARGC1A and PPARA genes in Lithuanian football players.

The aim of this study was to determine the impact of ACE (I/D), PPARGC1A (G/A) and PPARA (G/C) polymorphisms on footballers performance among 199 Lithuanian professional footballers and 167 sedentary, healthy men (controls). Genotyping was performed using polymerase chain reaction and restriction fragment length polymorphism methods on DNA from leucocytes. Results revealed that the angiotensin-1-coverting enzyme gene (ACE) genotype distribution was significantly different between total football players group (II 23.
