research has shown that chronic, long and exhausting endurance training programs cause iron deficiency. this problem can have a negative effect on physical performance. the aim of this research was to study the effect of endurance training and iron supplement on anemic indexes [hemoglobin (hb), hematocrit (hct), red blood cell (rbc), total iron binding capacity (tcbc) and ferritin], and cytochr...

Acute tyrosine ingestion is thought to improve aerobic endurance, muscle strength and endurance, and anaerobic power of men undergoing severe physiologic stress. In a double-blind, crossover study, 20 men (32 ± 1 y old) underwent 2 loadcarriage treadmill sessions, 1 after taking tyrosine (150 mg/kg L-crystalline tyrosine) and 1 after taking placebo. Tyrosine dosage was based on subject weight a...

Choline plays a central role in many physiological pathways, including neurotransmitter synthesis (acetylcholine), cell-membrane signaling (phospholipids), lipid transport (lipoproteins), and methyl-group metabolism (homocysteine reduction). Endurance exercise might stress several of these pathways, increasing the demand for choline as a metabolic substrate. This review examines the current lit...

Physical activity is the one important factor which affects the skeletal muscle function. Regular physical activity is recommended in youth today to improve the physical and mental well being. The aim of this study is to assess the skeletal muscle function in sedentary and ph...

Quality of life of diabetic patients is not a new concept in literature. The contentious issue however is whether factors associated in literature with quality of life apply to diabetic patients in Uganda. A sample of 219 outpatients attending Mulago diabetic clinic--a national referral hospital in Uganda--is used to provide an understanding of this issue. Quality of life is assessed in the dim...

BACKGROUND In modern society, decreased physical activity and/or changes in quality and quantity of nutritional intake contribute to obesity and lifestyle diseases that result in economic costs, both to society and to individuals. AIMS To measure physical fitness and body mass index (BMI) and to assess their association with sickness absence in male soldiers. METHODS Data regarding BMI and ...

To compare regimens of concurrent strength and endurance training, 26 male basketball players were matched for stature, body composition, and physical activity level. Subjects completed different training programs for 7 weeks, 4 days per week. Groups were as follows: (a) the strength group (S; n = 7) did strength training; (b) the endurance group (E; n = 7) did endurance training; (c) the stren...
