13. Two water environment adaptation models enhance motor behavior and improve the success of the lactate minimum test in swimming rats
Abstract AIMS This study was designed to investigate the effects of 14 water environment adaptation days on motor behavior and physiological condition of swimming rats. METHODS Sixty male Wistar rats were divided into four groups-baseline (Bl) and control (Co) groups-which did not perform the water environment adaptation; and sub (SubAnT) and (SupraAnT) an

14. Effects of aerobic, anaerobic, and concurrent training on bone mineral density of rats
Abstract A sample of 39 rats were divided into the following groups: baseline (BL); aerobic training (ET4 and ET8); anaerobic training (ST4 and ST8); and concurrent training (CT4 and CT8). The aerobic training was performed by swimming with a load corresponding to 70% of the anaerobic threshold; the anaerobic training was performed by jumping in water with a

15. Is heart rate variability a feasible method to determine anaerobic threshold in progressive resistance exercise in coronary artery disease?
ABSTRACT Background Recent studies have shown that the magnitude of the metabolic and autonomic responses during progressive resistance exercise (PRE) is associated with the determination of the anaerobic threshold (AT). AT is an important parameter to determine intensity in dynamic exercise. Objectives To investigate the metabolic and cardiac autonomic re

16. Effects of continuous vs interval exercise training on oxygen uptake efficiency slope in patients with coronary artery disease
The oxygen uptake efficiency slope (OUES) is a submaximal index incorporating cardiovascular, peripheral, and pulmonary factors that determine the ventilatory response to exercise. The purpose of this study was to evaluate the effects of continuous exercise training and interval exercise training on the OUES in patients with coronary artery disease. Thirty-f

17. Interval training based on ventilatory anaerobic threshold increases cardiac vagal modulation and decreases high-sensitivity c-reative protein: randomized clinical trial in coronary artery disease
Background: Autonomic dysfunction and inflammatory activity are involved in the development and progression of coronary artery disease (CAD), and exercise training has been shown to confer a cardiovascular benefit. Objective: To evaluate the effects that interval training (IT) based on ventilatory anaerobic threshold (VAT) has on heart rate variability (H

18. Odor from anaerobic digestion of swine slurry: influence of pH, temperature and organic loading
Farm slurry management from storage and/or treatment is the main source of odors from swine production, which are determined by factors such as operational variations (organic loading), cleaning of facilities and animal diet (pH) or environmental conditions (temperature). The aim of this study was to evaluate the influence of pH, temperature and organic load

19. Utilização da variabilidade da frequência cardíaca para a identificação do limiar anaeróbio: uma revisão sistemática
O objetivo desta revisão sistemática foi investigar os níveis de correlação e/ou concordância entre o Limiar de variabilidade da frequência cardíaca (LVFC), identificado por meio dos índices RMSSD e SD1, e o limiar anaeróbio (LA) em amostras com diferentes condições clínicas e funcionais. A busca foi realizada por dois autores de forma independe

20. Differences in muscle strength after ACL reconstruction do not influence cardiorespiratory responses to isometabolic exercise
Objectives: To investigate whether the muscle strength decrease that follows anterior cruciate ligament (ACL) reconstruction would lead to different cardiorespiratory adjustments during dynamic exercise. Method: Eighteen active male subjects were submitted to isokinetic evaluation of knee flexor and extensor muscles four months after ACL surgery. Thigh c

21. Cardiorespiratory fitness, pulmonary function and C-reactive protein levels in nonsmoking individuals with diabetes
The objective of this study was to evaluate cardiorespiratory fitness and pulmonary function and the relationship with metabolic variables and C-reactive protein (CRP) plasma levels in individuals with diabetes mellitus (DM). Nineteen men with diabetes and 19 age- and gender-matched control subjects were studied. All individuals were given incremental cardio

22. Determination of anaerobic threshold through heart rate and near infrared spectroscopy in elderly healthy men
BACKGROUND: Aging leads to low functional capacity and this can be reversed by safe and adequate exercise prescription. OBJECTIVE: The aim of this study was to identify the anaerobic threshold (AT) obtained from the V-slope method as well as visual inspection of oxyhemoglobin ( O2Hb) and deoxyhemoglobin (HHb) curves and compare findings with the heter

23. Exercise prescription using the heart of claudication pain onset in patients with intermittent claudication
OBJECTIVE: To assess the acute metabolic and cardiovascular responses to walking exercise at an intensity corresponding to the heart rate of claudication pain onset and to investigate the effects of a 12-week walking training program at this intensity on walking capacity. METHODS: Twenty-nine patients with intermittent claudication were randomly allocated t

24. Association between muscle strength and the cardiopulmonary status of individuals living with HIV/AIDS
OBJECTIVE: The purpose of this study was to compare aerobic function [anaerobic threshold (%VO2-AT), respiratory compensation point (%VO2-RCP) and peak oxygen uptake (VO2peak)] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile
