The aim of this study was to analyze the effect of an increase in training frequency on exercise-induced fatigue by using a systems model with parameters free to vary over time. Six previously untrained subjects undertook a 15-wk training experiment composed of 1) an 8-wk training period with three sessions per week (low-frequency training), 2) 1 wk without training, 3) a 4-wk training period w...

Glucose ingestion during exercise attenuates activation of metabolic enzymes and expression of important transport proteins. In light of this, we hypothesized that glucose ingestion during training would result in 1) an attenuation of the increase in fatty acid uptake and oxidation during exercise, 2) lower citrate synthase (CS) and beta-hydroxyacyl-CoA dehydrogenase (beta-HAD) activity and gly...

constant breastfeeding that depends on the family support. fathers' involvement is as an important factor of successful breastfeeding. the aim of this study was to evaluate the influence of fathers' participation in constant breastfeeding in vali-e-asr hospital, tehran, iran. this interventional study was piloted on spouses of pregnant women participating in pregnancy courses. the case group co...

The purposes of this study were 1) to determine the extent to which endurance training reduces the functional deficit induced by lengthening contractions in the soleus (Sol) muscle and 2) to determine whether young and old rats training at a comparable relative exercise intensity would demonstrate a similar protective effect from lengthening-contraction-induced injury. Young (3-mo-old) and old ...

PURPOSE The purpose of this study was to determine whether endurance and strength hand grip exercises during 3-week upper limb immobilization preserve muscle oxidative capacity, endurance performance and strength. METHODS Ten healthy adult men underwent non-dominant forearm immobilization by plaster cast for 21 days. Five healthy adult subjects were designated as the immobilization (IMM) grou...

conclusions the findings of this study proved that eight-week interval endurance rope training can have positive effects on lymphocyte abca1 protein expression (as gatekeeper of reverse cholesterol process) and lipid profiles among overweight and obese boy adolescents. objective the current study aimed to investigate abca1 expression in lymphocytes, plasma apolipoprotein a-i and hdl-c in respon...

BACKGROUND Popular Brazilian medicine uses Heteropterys aphrodisiaca infusion as a tonic or stimulant, for the treatment of nervous debility and breakdown and for muscle and bone weakness. This study investigated the effects of Heteropterys aphrodisiaca infusion on the tendon properties and extracellular matrix of rats under endurance training. METHODS Wistar rats were grouped as follows: CS-...

abstract back grand: early obesity and its transfer to the adult, increases likelihood incidence of coronary artery disease (cad). atp-binding cassette transporter) abca1) as a member of the abc transporters family plays a crucial role in reverse cholesterol transport and cad prevention. objective: the purpose of this study was to investigate abca1 expression in lymphocytes, plasma apolipoprote...
