the purpose of this study was to investigate the interference effect of concurrent strength and endurance training on maximum strength and vo2max in non-athletes. for this purpose, 34 sedentary healthy men (mean age 22±1.18 years, height 173.61±6.48 cm, and weight 56.13±8.50 kg) voluntarily participated in this study. initially, subjects were randomly assigned to one of four training groups: st...

BACKGROUND Overweight and obese children are at increased risk of a wide range of health conditions including respiratory diseases. In addition, inactivity can decrease pulmonary function. This study assessed the effect of obesity and inactivity on pulmonary function impairment in adolescents. MATERIALS AND METHODS This study was conducted on 80 adolescents. Subjects were divided into two gro...

BACKGROUND The aim of this study was to analyze the influence of active and passive smoking on cardiorespiratory responses in asymptomatic adults during a sub-maximal-exertion incremental test. METHODS The participants (n = 43) were divided into three different groups: active smokers (n = 14; aged 36.5 ± 8 years), passive smokers (n = 14; aged 34.6 ± 11.9 years) and non-smokers (n = 15; aged ...

OBJECTIVE To establish the level of cardiorespiratory fitness and the rate of decrease in maximal aerobic capacity according to age in patients with chronic low back pain and compare these with normative data. DESIGN Prospective case series with historical controls. SUBJECTS/PATIENTS Seventy patients with chronic low back pain. METHODS A maximal cycle ergometer protocol was used to measur...

The study determined the relationship between physical activity (PA) and risk factors of obesity among primary school children (boys: mean age 11.17±1.29, n=678; girls: mean age 10.88±1.27, n=683) in Limpopo and Mpumalanga provinces, South Africa. The children were classified according to age and sex-specific body mass index (BMI) categories (underweight: 0<18, normal weight: 18.5<25, overweigh...

INTRODUCTION The maximal oxygen uptake (VO2max) can be defined as the maximum integrated capacity of the pulmonary, cardiovascular and muscular systems to uptake, transport and utilize O2, respectively (Poole et al., 2008). Usually measured by the incremental exercise test in the treadmill or cycle ergometer, the VO2max test has become a cornerstone in clinical and applied physiology involving ...

Previous reports indicate that among healthy individuals low aerobic fitness (AF) and high body-mass index (BMI) predict poor neurocognition and daily-functioning. It is unknown whether these associations extend to disorders characterized by poor neurocognition, such as schizophrenia. Therefore, we compared AF and BMI in individuals with schizophrenia and non-clinical controls, and then within ...
