BACKGROUND Cardiac dysfunction after brain death has been documented, but its mechanisms remain unclear. Myocardial ischemia has been suggested as a possible cause. The aim of the present study was to investigate the existence of an imbalance between myocardial oxygen delivery and demand as a possible cause of myocardial dysfunction in brain-dead pigs. METHODS AND RESULTS Interstitial myocard...

abstract background: athletes’ recovery is important in improving their performance. nutritional strategies can be effective in enhancing recovery rate. choosing the best food items in appropriate intervals can play effective roles in resynthesis of fuels and recovery of muscle injury. beverage micro and macronutrient content are helpful in fuel restoration. in this study, we assess the effects...

EROOKS, GEORGE A., KAY E. BRAUNER,ANDROBERTG.CASSENS. Glvcogen synthesis and metabolism of lactic acid after exercise. Am. J. Physiol. 224(5) : 1162-I 166. 1973.-The hypothesis that postexercise 02 consumption is attributable to the reconversion of lactic acid to glycogen was tested. Blood, muscle, and liver lactate, muscle, and liver glycogen and blood glucose concentrations were studied as a ...

Background and Objectives: Strenuous exercises have been shown to induce inflammation. However, consumption of products rich in antioxidants such as vitamin C may enhance this effect. The purpose of this study was to assess effects of vitamin C supplementation on C-reactive protein, lactate and blood pressure following resistance exercise in overweight men. Materials and Methods: In a randomiz...

s / Journal of Equine Veterinary Science 34 (2014) 76 76 x106sperm/mL. Sperm recovery rate after centrifugation was lower in low concentration samples (p<0.001). Mean lactate concentration at T0 was the same in all three groups and directly correlated with raw semen volume (r1⁄40.5032; p1⁄40.0103). Lactate concentrations at T0 and T24 were not correlated. Compared to T0, lactate concentration w...

In this study, we examined the acute effects of a 5-day daily whole-body vibration (WBV) training on electromyography (EMG) responses of the m. rectus femoris and m. gastrocnemius lateralis, heart rate (HR, continuously recorded), and blood lactate levels. The purpose of the study was to investigate the adaptation of muscle activity, heart rate and blood lactate levels during 5 days of daily tr...

AIM To study pattern-reversal visual evoked potentials (VEP) in patients with relapsing-remitting multiple sclerosis on interferon beta-1a treatment. METHODS In a randomized, prospective, non-blinded, placebo-uncontrolled study, VEP were studied in 9 patients (18 eyes) with relapsing-remitting multiple sclerosis treated with interferon. Three of them have had an episode of unilateral optic ne...

Competitive ski mountaineering (SKIMO) has achieved great popularity within the past years. However, knowledge about predictors of performance and physiological response to SKIMO racing is limited. Therefore, 21 male athletes split into two groups (elite: VO2max 71.2 ± 6.8 ml· min-1· kg-1 vs. sub-elite: 62.5 4.7 kg-1) were tested analysed during a vertical race simulation (523 m elevation gain)...

BACKGROUND Blood flow limitation to exercising muscles engages the muscle reflex during exercise, evoking an increase in heart rate (HR), blood pressure (BP), and muscle sympathetic nerve activity (MSNA). METHODS AND RESULTS In the current study, we examined forearm flow and autonomic responses to ischemic handgrip in young and older subjects. We studied 6 younger subjects (mean age 23.5+/-2....
