Evaluating bioenergetic pathway contributions from single to multiple sprints.

This study aims to investigate the changes in bioenergetic pathway contributions during repeated sprint exercises with an increasing number of repetitions. Twelve male amateur soccer players executed a single 20 m sprint and three repeated-sprint protocols (5 × 20 m, 10 × 20 m, 15 × 20 m with 15-second rest intervals), analyzing oxidative, glycolytic, and ATP-PCr energy pathways using the PCr-LA-O2 method. Findings revealed a significant decline in energy expenditure and performance outputs as the number of sprint repetitions increased.

Evaluation of Oral and Dental Health Results and Competition Stress Levels of Adolescent Athletes in Different Winter Sports Branches.

Background:  The aim of the present study was to examine the findings of the intraoral examinations of the 12-16 years old novice (control) and elite athletes across the winter sports branches, which were alpine discipline skiing, snowboarding, biathlon, ski jumping, and ice hockey. Besides, the study aimed to determine the intra- and inter-group relationships by comparing the athletes salivary stress biomarker levels at precompetition, during-match, and post-competition stages.

Methods:  Ninety-one athletes (71 elite, 20 novice) participated in our study.

Effects of Ramadan intermittent fasting on performance, physiological responses, and bioenergetic pathway contributions during repeated sprint exercise.

Introduction: This investigation aims to elucidate the impact of Ramadan intermittent fasting on performance, physiological responses, and bioenergetic pathway contributions during repeated sprints.

Methods: Fourteen active male Muslim athletes (age = 22.4 ± 1.

Effects of exercise on serum ischemia-modified albumin, brain natriuretic peptide and copeptin levels in boxers and kick boxers.

Introduction: boxing and kick boxing are combat sports that can cause severe head, neck, face and hand injuries during fighting. Then, traumatic brain injury (TBI) incidence is high in these sports. Ischemia-modified albumin (IMA), brain natriuretic peptide (BNP) and copeptin have diagnostic and prognostic value for cardiac and non-cardiac ischemic events.

The Effect of Citrulline/Malate on Blood Lactate Levels in Intensive Exercise.

The purpose of this study was to examine the effects of Citrulline/Malate supplementation with intensive training on blood lactate level in active handball players. The athletes were subjected to intense training for 4 weeks, 4 days a week, mainly pre-season strength and technique training. In this training period, stimol group (n = 11) athletes were given stimol 3 times a day as 1 g for breakfast, 1 g for lunch, and 1 g for dinner while the placebo group (n = 11) athletes were given only placebo in the same dosage and the same color at the same time.

Tc-99m MDP bone scintigraphy in the evaluation of the joint damage in asymptomatic alpine ski racers.

Aim: To evaluate the role of 99m-technetium methylene diphosphonate (Tc-99m MDP) bone scintigraphy on the detection of joint damage in asymptomatic alpine ski racers.

Materials And Methods: This study included 20 male asymptomatic alpine ski racers (age range: 18-21 years). None of the skiers had a history of ski crashes.
