Effectiveness of high-fat and high-carbohydrate diets on body composition and maximal strength after 15 weeks of resistance training.

Purpose: The aim of this study was to compare High Carbohydrates Low Fat (HCLF) and Low Carbohydrate High Fat (LCHF) diets in terms of changes in body composition and maximal strength.

Patients/methods: The study involved 48 men aged 25 ​± ​2.5, divided into two groups, one of which (n ​= ​23) was following the LCHF diet and the other (n ​= ​25) the HCLF diet.

Association of Myostatin Gene Polymorphisms with Strength and Muscle Mass in Athletes: A Systematic Review and Meta-Analysis of the MSTN rs1805086 Mutation.

Polymorphism (rs1805086), , () of the myostatin gene () has been associated with a skeletal muscle phenotype (hypertrophic response in muscles due to strength training). However, there are not enough reliable data to demonstrate whether rs1805086 K and R allelic variants are valid genetic factors that can affect the strength phenotype of athletes' skeletal muscles. The aim is to conduct a systematic review and meta-analysis of the association of rs1805086 polymorphism with the strength phenotype of athletes.

Effects of Multi-Ingredient Pre-Workout Supplement and Caffeine on Bench Press Performance: A Single-Blind Cross-Over Study.

The problem addressed in this study is the appropriateness of using different pre-training supplementation strategies and their ability to improve training performance and psychological measures. The aim of the study is the evaluation of the effectiveness of a multi-ingredient pre-workout supplement (MIPS) containing beta-alanine, L-citrulline malate, arginine alpha-ketoglutarate, L-taurine, L-tyrosine and caffeine compared to an exact dosage of anhydrous caffeine in bench press strength endurance, feeling scale (FS), felt arousal scale (FAS) and session rating of perceived exertion (sRPE). A group of fifteen resistance-trained males, weighing 83.

EXPOSURE LEVELS OF UKRAINIAN POPULATION IN THE CONTEXT OF AN ACTION PLAN TO REDUCE INDOOR RADON LEVELS.

Objective: To analyze and evaluate the available information to indoor radon concentration in the context of theimplementation of the radon action plan.

Object Of Study: indoor radon-222 in dwellings by area and corresponding radiation risks of the population. Measurements were performed using passive track radonometry.

[Inflammatory factors and immunophenotypes in adjustment disorders].

Aim: To identify inflammatory and autoimmune markers (enzymatic activity of leukocyte elastase (LE), functional α1-proteinase inhibitor (α1-PI), the level of autoantibodies to neurospecific antigens S100b and myelin basic protein (MBP)) as well as phagocytic activity of blood neutrophils of patients with disorders of adaptation, to determine certain immunophenotypes and analyze their possible relationships with disease characteristics.

Material And Methods: The study included 40 patients with adaptation disorders, mostly women. Diagnostic evaluation and clinical qualification of patients was carried out in accordance with ICD-10: 'Adjustment disorder' (F43.
