The textbook is a pedagogical tool that provides students and professionals with scientific information. As exercise is an important strategy for the prevention and treatment of noncommunicable diseases, such as type 2 diabetes mellitus (T2DM) and arterial hypertension, the presence of correct and up-to-date scientific information in exercise…

Purpose: The present study aimed to investigate associations between hormonal profile (cortisol and testosterone) and the psychobiological aspects of Paralympic athletes during a competitive season. Method: Male Brazilian Paralympic swimmers (n=11) were evaluated in three Training Camps (TC) during the cycle of training for the Paralympic Games…

Purpose: To examine the capacity of physiological variables and performance to predict peak oxygen consumption (peak VO[subscript 2]) in children and adolescents living with HIV. Method: Sixty-five children and adolescents living with HIV (30 boys) aged 8-15 years, participated in the study. Peak VO[subscript 2] was measured by breath-by-breath…

Bolstered by evidence of the health benefits of exercise, health professionals advise their patients about it. Thus these professionals should have a basic knowledge of exercise physiology. In Brazil, a graduate degree is not mandatory, so for many health providers, the only opportunity to receive information on exercise physiology content is…

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…

Purpose: This study aimed to compare the energy expenditure and intensity of active video games to that of treadmill walking in children and adolescents. Method: Seventy-two boys and girls (aged 8-13 years) were recruited from local public schools. Energy expenditure and heart rate were measured during rest, during 3-km/hr, 4-km/hr, and 5-km/hr…

Purpose: This study aimed to investigate the effects of water-based aerobic training on the lipid profile and lipoprotein lipase (LPL) levels in premenopausal women with dyslipidemia. Method: Forty women were randomly assigned to: aquatic training (WA; n = 20) or a control group (CG; n = 20). The WA group underwent 12 weeks of water-based interval…

Purpose: The purpose of this paper was to assess the knowledge on sport and exercise science held by a sample of Brazilian physiotherapists, nutritionists and physical educators. Design/methodology/approach: A cross-sectional research design was used. The answers given by 1,147 professionals (300 physiotherapists, 705 physical educators and 142…

Purpose: Maximal tests conducted on land are not suitable for the prescription of aquatic exercises, which makes it difficult to optimize the intensity of water aerobics classes. The aim of the present study was to evaluate the maximal and anaerobic threshold cardiorespiratory responses to 6 water aerobics exercises. Volunteers performed 3 of the…

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s[superscript -1], corresponding to 11.1% below velocity at the ventilatory…

Purpose: To quantify creatine kinase (CK) activity changes across time following an acute bout of whole-body vibration (WBV) and determine the association between changes in CK activity and jumping performance. Method: Twenty-six elite young basketball players were assigned to 3 groups: 36-Hz and 46-Hz vibration groups (G36 and G46, respectively)…

The cause-effect relationship between lactic acid, acidosis, and muscle fatigue has been established in the literature. However, current experiments contradict this premise. Here, we describe an experiment developed by first-year university students planned to answer the following questions: 1) Which metabolic pathways of energy metabolism are…

Study aim: To determine the effects of indoor cycling training combined with restricted diet, lasting 12 weeks, on serum lipid concentrations in obese women. Material and methods: Twenty women aged 23.8 [plus or minus] 3.6 years were randomly assigned into two groups: control (C) and experimental (E), the latter subjected to indoor cycling at…
