Purpose: This study aimed to examine the activities of heart rate variability (HRV) and cortisol secretion as markers of the autonomous nervous system (ANS) and the hypothalamic-pituitary-adrenal axis (HPA) during the menstrual cycle in female athletes. Method: Saliva samples of the participants (n = 28) were collected successively at 0, 15, 30,…

Previously most studies indicated that high intensity training is a powerful stimulus to acute increases in blood testosterone hormone levels in males. The testosterone responses to exercise in females are controversial; while some studies have shown increases, others have suggested no change. The aim of this study was to determine alterations in…

Here we describe an approach and overall concept of how to train undergraduate university students to understand basic regulation and integration of glucose and fatty acid metabolism in response to fasting, intake of carbohydrates, and aerobic exercise. During lectures and both theoretical and practical sessions, the students read, analyze, and…

Ischemic preconditioning (IPC) has recently been experimented with the hypothesis that it can acutely improve exercise performance. IPC's ergogenic effects have been a novel approach to improve anaerobic power and sprint performances. Since the beneficial effects of the underlying mechanisms on anaerobic power have not been clearly understood, the…

This study aims to investigate the effect of acute handball training on the irisin, leptin, insulin and blood lipids. 19 male handball players, who are between 15-17, regularly train and play for Turkish Super Young League, have been volunteer for this research. All of the members of this research group are healthy and play handball for at least 3…

Purpose and Methods: To compare the effects of a set of 12--30 min, maximal effort, constant load cycle bouts (HICT) to 12 short work: shorter rest (10 s: 5 s) interval sessions (INT) of similar duration and effort, performed on alternate days over 4 weeks, on performance and V?O[subscript 2] l.min[superscript -1]. INT sessions consisted of…

The purpose of this study is to determine whether there is a difference between physiological responses to the small-sided games often applied during soccer trainings by changing the dimensions of the fields, the number of players, duration and the rules of the games. 16 sports people, who play soccer in Turkey Hearing- Impaired National soccer…

The Live High-Train High (LHTH) model altitude training is required to sojourn over 2000m more than 3 weeks. In such altitudes response that may cause decreased living, sleeping and training quality. In these cases coaches may approach with suspicion to LHTH can be harmful for their training intensity edgewise training quality. The aim of this…

Purpose: The main purpose of the present study was to determine physiological responses in wheelchair basketball (WB) matches in relation to heart rate (HR), match load (ML), differentiated perceived exertion (dRPE), lactate concentrations (LA), and tympanic temperature (TEMP), while specifying the individual player's playing time during different…

Purpose: The aim of this study was to compare the widely used accelerometer activity cut-points derived from the absolute moderate intensity recommendation (3-6 METs), with relative intensity cut-points according to maximal cardiorespiratory fitness (46%-63% VO[subscript 2max]) and to individual lactate thresholds (LT1 and LT2) in postmenopausal…

Delivering successful performance in sports depends on physical fitness. Unless the physical and physiological structure is in accordance with the requirements of the sports branch, a high performance in sports cannot be realized fully (Çakmakçi, 2002). Therefore, it is important to define and improve performance parameters such as body…

90-95% of vitamin D which has the supreme function of regulating many metabolisms in tissues and organs, is taken from the sunlight through skin. Since wrestling is performed in sun-protected sports halls, we think that a vitamin D replacement will improve the performance of wrestlers, especially as the limited exposure to sunlight is compared to…

Objective: This study aims at examining the body composition of male football players who perform regular football training by Bioelectrical Impedance (BIA) method and comparing it with a healthy control group and investigating the effect of regular exercise on body composition. Materials and Methods: A total of 60 people participated in the…

The purpose of this study was to investigate the effect of post-challenge acute values of serum cortisol levels in elite and sedentary athletes before aerobic exercise. This study included 22 elite middle-distance runners from various clubs around Turkey and 16 voluntary non-athlete men. The Cooper test was applied to study subjects. Heart rate…

This study aims to analyze running distances in national teams during 2010 and 2014 FIFA World Cup and to propose a new program which estimates oxygen consumption capacity based on running distances. The data were evaluated by SPSS 22.0 statistical package program. The findings demonstrate that among teams participating in 2010 and 2014 FIFA World…
