BACKGROUND Aerobic capacity tests are important to evaluate exercise programs and to encourage individuals to have a physically active lifestyle. Submaximal tests, if proven valid and reliable could be used for estimation of maximal oxygen uptake (VO2max). The purpose of the study was to examine the criterion-validity of the submaximal self-monitoring Fox-walk test and the submaximal Åstrand cy...

conclusions children engaged with regular football practice presented enhanced physical fitness and autonomic function, by increasing vagal tone at rest. results the anthropometric and body composition characteristics were similar in both groups (p > 0.05). the groups were also similar in time spent daily on moderate-to-vigorous physical activities (fg vs. cg: 114 ± 64 vs. 87 ± 55 minutes; p > ...

background: despite the widespread use of respiratory protection equipment in different jobs, the effects of these devices on people’s physiological responses are not well recognized as yet. therefore, the aim of this study is to evaluate the effect of the air purifying respiratory protection equipment on the heart rate. methods: this experimental study was performed in a climate chamber under ...

BACKGROUND Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulatory technique and has previously been shown to enhance submaximal exercise by reducing rating of perceived exertion (RPE). The present study examined the effects of tDCS on high-intensity self-paced exercise in temperate conditions and fixed followed by maximal exercise in the heat; it was hypothesised that ...

Introduction: Breast cancer is the most common and deadliest among women. Objectives: The aim of this study was to evaluate effect 10-week aerobic exercise on cardiac function overweight female breast survivors. Patients Methods: This triple-blinded randomized clinical trial carried out 25 survivors (age range; 30-55 years). training protocol performed for 10 weeks with an intensity 40 75% maxi...

PURPOSE To compare peak exercise oxygen consumption (VO2peak) of healthy individuals with asymptomatic individuals with probable heart disease. METHODS Ninety-eight men were evaluated. They were divided into two groups: 1) 39 healthy individuals (group N) with an age range of 50 +/- 4.6 years; and 2) 59 asymptomatic individuals with signs of atherosclerotic and/or hypertensive heart disease (...

conclusion our findings support prone positioning for premature infants. therefore, it is advisable to nicu staff that if there is no obstacle for changing the infant’s position, prone position in infants with respiratory complications during receiving n-cpap in nicu can be useful. regarding the fact that prone position is a risk factor for sudden infant death syndrome , prone position should b...

Our first aim was to compare the anaerobic threshold (AnT) determined by the incremental protocol with the reverse lactate threshold test (RLT), investigating the previous cycling experience effect. Secondarily, an alternative RLT application based on heart rate was proposed. Two groups (12 per group-according to cycling experience) were evaluated on cycle ergometer. The incremental protocol st...

Ketamine (1 mg . kg-1) or thiopentone (4 mg . kg-1) was used to induce anaesthesia for Caesarean section in 62 normotensive patients. During induction of anaesthesia and before laryngoscopy, blood pressure did not change in either group (preinduction systolic blood pressure, 131 mmHg, and diastolic blood pressure, 75 mmHg). When laryngoscopy and intubation were performed, mean blood pressures o...
