The aims of this study were to quantify the effects of factors such as mode of exercise, body composition and training on the relationship between heart rate and physical activity energy expenditure (measured in kJ x min(-1)) and to develop prediction equations for energy expenditure from heart rate. Regularly exercising individuals (n = 115; age 18-45 years, body mass 47-120 kg) underwent a te...

The purpose of this study was to investigate the benefits of a pedometer and a cognitive-behavioural group intervention for promoting physical activity (PA) in type 2 diabetes patients. We recruited 41 participants and randomized them into an intervention group (IG) (n=20) and a control group (CG) (n = 21). The intervention consisted of five sessions within 12 weeks, a booster session after 22 ...

ISSUE ADDRESSED Whether posters promoting stair use are effective in increasing objectively measured physical activity in a sample of New Zealand professional employees. METHODS Forty-six participants (27 men and 19 women) recruited from two professional worksites wore one sealed pedometer during all waking hours (total physical activity [TPV]), and another sealed pedometer during working hou...

Assessing levels of physical activity (PA) and providing feedback about these levels might have an effect on participant's PA behavior. This study discusses the effect of different levels of feedback--from minimal to use of a feedback display and coach--on PA over a 4-week intervention period. PA was measured at baseline, during and immediately after the intervention. Participants (n=227) were ...

We investigated the usefulness of the oxygen intake efficiency slope (OIES) as a submaximal measure of cardiorespiratory functional reserve. OIES was derived from the relationship between oxygen consumption (VO2; ml/min) and minute ventilation (VE; l/min) during incremental exercise, which was determined by the following equation: VO2 = a logVE + b, where "a" represents OIES, which shows the ef...

Pedometer use and step count goals have become popular in physical activity (PA) interventions in different settings. Previous pedometer-based workplace interventions were short term, uncontrolled and executed outside Europe. This European quasi-experimental study evaluated the effects of a 20-week pedometer-based PA workplace intervention. Pedometer-based and self-reported PA from one interven...

OBJECTIVE To determine whether pedometers can be used to measure physical activity in dogs. DESIGN Cross-sectional study. ANIMALS 26 dogs. PROCEDURE To determine pedometer accuracy, number of steps recorded with the pedometer as dogs walked, trotted, and ran for a distance of approximately 30 m (100 ft) at each gait was compared with actual number of steps. Dogs and owners then wore pedom...

OBJECTIVES To examine if receiving a pedometer along with an intervention toolkit is associated with increased physical activity, aerobic fitness and better self-rated health among individuals with low levels of physical activity or fitness. METHODS The intervention was nested in the Danish Health Examination Survey (DANHES) and carried out in 2008. Participants were randomly assigned to eith...

The study purpose was to investigate changes in the content of testosterone and cortisol blood qualified athletes after testing them determine their maximal oxygen consumption (VO2max). 
 Materials methods. Thirty-seven international level athletes: 15 biathletes, 12 rowers, 6 boxers, 4 modern pentathletes participated this study. test evaluate VO2max used exercise increasing intensity on ...
