The purpose of this study was to determine the aerobic training intensity from the maximal and submaximal running exercise in 21 untrained adult men. To accomplish this, we evaluated the relationship between physiological (oxygen intake and heart rate) and physical parameters (running speed) of training intensity, and determined the training intensity at the submaximal exercise. Oxygen intake a...

This study investigated differences in average VO2 of maximal effort interval running to maximal effort constant rate running at lactate threshold matched for time. The average VO2 and distance covered of 10 recreational male runners (VO2max: 4158 ± 390 mL · min(-1)) were compared between a maximal effort constant-rate run at lactate threshold (CRLT), a maximal effort interval run (INT) consist...

BACKGROUND At the maximal Cardiopulmonary Exercise Testing (CPET), several ventilatory variables are analyzed, including the ventilatory equivalent for oxygen (VE/VO2). The minimum VE/VO2 value reflects the best integration between the respiratory and cardiovascular systems and may be called "Cardiorespiratory Optimal Point (COP)". OBJECTIVE To determine the behavior of the COP according to g...

PURPOSE Collecting waste is regarded as a benchmark for "particularly heavy" work. This study aims to determine and compare the workload of refuse workers in the field. We examined heart rate (HR) and oxygen uptake as parameters of workload during their daily work. METHODS Sixty-five refuse collectors from three task-specific groups (residual and organic waste collection, and street sweeping)...

UNLABELLED BACKGROUND Whey protein isolates (WPI) supplementation is known to improve resistance training adaptations. However, limited information is available on the effects of WPI plus carbohydrate (CHO) supplementation on endurance training adaptations. METHOD Six endurance trained male cyclists and triathletes (age 29 ± 4 years, weight 74 ± 2 kg, VO2 max 63 ± 3 ml oxygen. kg-1. Min-1,...

The purpose of this study was to examine the effects of two iso-kilocaloric (837.2 kJ) pre-exercise meals: a low glycemic meal (LGM) vs. a high glycemic meal (HGM) and a placebo meal in recreationa...

The aim of this pilot study was to evaluate the accuracy of a simple step-test procedure supplemented by the measurement of heart rate (HR) (STEP1) to assess the cardiorespiratory capacity i.e., maximal oxygen consumption (VO2max) of Thai workers. The subjects comprised 18 men and 17 women. Their ages varied from 19 to 20 years and all were physically active. The subjects performed three tests:...

Strength training (ST; high intensity/low volume/long rest) has been used in several populations, including children, young adults, and older adults. However, there is no information about circuit weight training (CWT; low intensity/high volume/short rest) in apparently healthy postmenopausal women. The purpose of the present study was to analyze the effects of high-intensity ST and circuit tra...
