Heart Rate and Body Temperature Evolution in an Interval Program of Passive Heat Acclimation at High Temperatures (100 ± 2 °C) in a Sauna.

Heat exposure provokes stress on the human body. If it remains constant, it leads to adaptations such as heat acclimation. This study aims to observe the evolution of heart rate (HR), core temperature (Tcore), and skin temperature (Tskin) in an intervallic program of exposure to extreme heat.

Effect of Handgrip Training in Extreme Heat on the Development of Handgrip Maximal Isometric Strength among Young Males.

The aim of this study was to evaluate the acute and adaptive effects of passive extreme heat (100 ± 3 °C) exposition in combination with a strength training protocol on maximal isometric handgrip strength. Fifty-four untrained male university students participated in this investigation. Twenty-nine formed the control group (NG) and 25 the heat-exposed group (HG).

Effects of Twelve Sessions of High-Temperature Sauna Baths on Body Composition in Healthy Young Men.

The health benefits of sauna baths are attracting ever-increasing interest. Therefore, the purpose of this study was to evaluate the effects of 12 high-temperature (100 °C) sauna baths on body composition of 23 healthy young men, divided into a control group (CG) and a sauna group (SG). Both groups were initially evaluated by dual-energy X-ray absorptiometry (DXA), after which the SG experienced 12 sessions of sauna baths at high temperatures (100 °C).

[Comparative study of the variables of physical fitness and health among young athletes and sedentary males].

Introduction: today, the practice of physical activity during adolescence brings important physical-health benefits that help develop a future well-being in later life.

Objectives: the objective of this comparative study was to evaluate the physical condition, body composition and cardiorespiratory capacity among young athletes and sedentary people of the Autonomous Community of Extremadura (Spain).

Methods: two hundred and twenty-five male subjects, aged between 12 and 18 years, were divided into two groups: 175 athletes, divided into aerobic group (AEG), anaerobic group (ANAEG) and mixed sports group (MG); and 50 sedentary (SG) or control group.

Serum concentration of cobalt, molybdenum and zinc in aerobic, anaerobic and aerobic-anaerobic sportsmen.

Background: The aim of the present study was to determine changes in the serum concentrations of trace elements Cobalt (Co), Molybdenum (Mo) and Zinc (Zn) among high-level sportsmen.

Methods: Eighty professional athletes of different metabolic modalities (aerobic, anaerobic and aerobic-anaerobic), were recruited before the beginning of their training seasons. Thirty-one sedentary participants of the same geographic area constituted the control group.
