The objective was to test the hypothesis that traditional and novel cardiometabolic risk factors would be significantly different in groups of men of different fatness and fitness. Total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, glucose, insulin, high-sensitivity C-reactive protein, alanine aminotransferase, aspartate aminotransferase...

  Purpose: This study investigated the effect of endurance activity on brain-derived neurotrophic   factor(BDNF), insulin-like growth factor 1(IGF-1) and its binding protein 3(IGFBP-3) in elderly   healthy individuals.   Materials and Methods: Eleven healthy old males (mean age of 68 ± 2.31 years old, height   of 177 ± 3.1 cm and weight of 79 ± 1.5 kg) were studied. Seventy two hours after maxi...

The aim of this study was to characterize untrained Nandi boys (mean age 16.6 years) from a town (n = 11) and from a rural area (n = 19) in western Kenya (altitude approximately 2000 m.a.s.l.) in regard to their body dimensions, oxygen uptake and physical activity level. The town boys had a mean maximal oxygen uptake (VO(2 max)) of 50 (range: 45-60) mL kg(-1) min(-1), whereas the village boys r...

Data on aerobic fitness and heart rate recovery in children are limited. This study was done to evaluate the relation between them in Indian school going children. Three hundred children of 7 to 10.5 years were recruited and their aerobic fitness was predicted using modified Harvard's step test (VO₂max) and 20 meter shuttle test (VO₂peak). The heart rate was monitored for 12 minutes post modifi...

BACKGROUND Mitochondrial disorders are generally not associated with a clear phenotype-genotype relationship, which complicates the understanding of the disease and genetic counseling. OBJECTIVE To investigate the relationship between the muscle and blood mitochondrial DNA mutation load and phenotype. DESIGN Survey. SETTING The Neuromuscular Research Unit, Rigshospitalet, Copenhagen, Denm...

SHVARTZ, E., Y. SHAPIRO, A. MAGAZANIK, A. MEROZ, H. BIRNFELD, A. MECHTINGER, AND S. SHIBOLET. Heatacclimation, physical fitness, and responses to exercise in temperate and hot environments. J. Appl. Physiol.: Respirat. Environ. Exercise Physiol. 43(4): 678-683, 1977. -Three groups of men with different ire, max (60.1, 47.7, and 35.6 ml*kg+min+) were administered two submaximal tests at 23”C, at...

OBJECTIVES It is known that exercise induces cardio-respiratory autonomic modulation. The aim of this study was to assess the cardio-pulmonary fitness by ultra-short heart rate variability. MATERIALS AND METHODS Study population was divided into 3 groups: Group-1 (n = 40) consisted of military sports man. Group-2 (n = 40) were healthy age-matched sedentary male subjects with normal body mass ...

BACKGROUND Schistosomiasis and soil-transmitted helminthiasis are important public health problems in sub-Saharan Africa causing malnutrition, anemia, and retardation of physical and cognitive development. However, the effect of these diseases on physical fitness remains to be determined. METHODOLOGY We investigated the relationship between schistosomiasis, soil-transmitted helminthiasis and ...
