the aim of this study was to assess the effect of four weeks of high intensity aerobic interval football training on aerobic performance indices in soccer players. 18 soccer players in iran azadegan league (age 21.88+2.24 yr, height 174.22+5.33 cm, weight 67.7+5.7 kg, body fat percent 12.38+3.29) volunteered to participate in this study and divided into two groups (training, 12 players; control...

Background and Purpose: Nowadays, total body resistance exercise has been added to instability training and has become popular for improving health and sports performance. Resistance training is a beneficial way to improve body composition and increase muscle strength. This study aims to evaluate the effect of suspension training (total resistance exercises [TRX]) with and without electrical mu...

Objective To establish normal reference ranges for cardiac valve crosssectional areas (CSAs) in preterm infants and their correlation with gestational age, body weight, and chronological age. Materials and Methods In a prospective study, 268 preterm babies fulfilling the criteria for inclusion were examined. Echocardiograms were performed to measure aortic, pulmonary, mitral, and tricuspid va...

two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

the present investigation was performed to determine the effect of long-term administration of sodium selenite on the biochemical indices and concentration of thyroid hormones in calves. sodium selenite solution was drenched at 0.1 and 0.25 mg per kg body weight for 12 weeks. higher dose produced characteristic symptoms of selenosis whereas mild symptoms were observed with lower dose. the toxic...

BACKGROUND An accurate estimate of preconception weight is necessary for providing a gestational weight gain range based on the Institute of Medicine's guidelines; however, an accurate and proximal preconception weight is not available for most women. We examined the validity of first trimester weights for estimating preconception body mass index category. METHODS Under identical measurement ...

l-carnitine as a water soluble derivative of lysine has a crucial biological role in lipid metabolism. present experiment was conducted to study the effect of l-carnitine supplementation into broiler and/or breeder diets on broilers' performance, blood related factors, carcass characteristics and immune system. l-carnitine was added to the broiler breeder's diets at levels of 0, and 6...

The study was conducted to optimize lighting schedule for pre-pubertal (12 to 22 weeks) Chinese native breed Pengxian yellow pullet. A total of 414 healthy pullets (10 weeks), with similar body weight were randomly distributed into three groups (n = 138) and housed in individual cages for up to 12 weeks of age in light controlled rooms and provided normal lighting schedule (10L:14D). At 12 to 1...

OBJECTIVE To compare growth and body composition in preterm infants with bronchopulmonary dysplasia (BPD) with normal healthy term infants during the first year of life. DESIGN Twenty nine preterm infants with BPD (mean (SD) gestational age 27.1 (1.6) weeks; birth weight 852 (173) g) were followed prospectively. Anthropometry and body composition determined by total body electrical conductivi...
