BACKGROUND Fibroblast growth factor 21 (FGF21) increases glucose uptake. It is unknown if FGF21 serum levels are affected by exercise. METHODOLOGY/PRINCIPAL FINDINGS This was a comparative longitudinal study. Anthropometric and biochemical evaluation were carried out before and after a bout of exercise and repeated after two weeks of daily supervised exercise. The study sample was composed of...

the present study aimed to assess changes in resting and maximum heart rates as primary indicators of cardiac autonomic function in metabolic syndrome (mets) patients and to determine their value for discriminating mets from non-mets. 468 participants were enrolled in this cross-sectional study and assessed according to the updated adult treatment panel iii (atp-iii) definition of mets. resting...

The present study was aimed to isolate a multiple herbicide resistant strain [(MHR)] of Anabaena variabilis exhibiting resistance against four common rice-field herbicides, viz., Arozin, Alachlor, Butachlor and 2,4-D. The multiple herbicide resistant (MHR) strain was isolated by spontaneous mutational techniques. Of the four spontaneously occurring mutants, Arozin resistant mutant (Ar-R) exhibi...

AGE ASSOCIATED DECLINES IN EXERCISE TIME TO EXHAUSTION AND VENTILATORY PARAMETERS IN TRAINED CYCLISTS. Frank B. Wyatt, Jason P. Mccarthy. JEPonline. 2002;6(1):1217. The purpose of this study was to investigate the cardiopulmonary parameters in a cross section of fit, aging cyclists to determine the associations between age, heart rate and ventilation on exercise time to exhaustion. Subjects wer...

BACKGROUND The previous investigations in diurnal variation of endurance sports performance did not reach a consensus and have been limited. This study would be a valuable resource for endurance sports trainers and event managers to plan their training and competition in a specific time of day. OBJECTIVES The aim of this study is to find out the diurnal variation in cardiovascular endurance p...

cardiac function during exercise is assumed to be important in determining exercise tolerance. the aim of this study was to evaluate hemodynamic changes of blood flow at anaerobic threshold and its effect on exercise tolerance. 24 patients with coronary artery disease were voluntarily divided into two groups of experimental (n=12) and control (n=12). the experimental group participated in 8 wee...

BACKGROUND Little is known about the metabolic and heart rate responses to a typical hatha yoga session. The purposes of this study were 1) to determine whether a typical yoga practice using various postures meets the current recommendations for levels of physical activity required to improve and maintain health and cardiovascular fitness; 2) to determine the reliability of metabolic costs of y...

OBJECTIVE To evaluate the effect of neuromuscular electrical stimulation (NMES) on cardiopulmonary function in healthy adults. METHOD Thirty-six healthy adults without a cardiac problem were enrolled. All patients were randomly assigned to either a control (17 subjects, mean age 29.41) or an electrical stimulation group (19 subjects, mean age 29.26). The electrical stimulation group received ...
