the purpose of this study was to determine and compare blood lactate, heart rate and blood pressure responses in arm and leg exercises and to determine the relationship between these variables and fatigue time during these two modes of exercises. 8 young professional karate players (mean age 18.90±2.20) volunteered to participate in this study. the subjects completed two ergometers: arm and leg...

background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...

the aim of this study was to determine the effect of pre-cooling on physiological, functional and perceptual variables in men in an exhaustive intense activity in a warm environment. 10 healthy athlete men (mean age 23.40±1.89 yr, weight 69.80±8.94 kg, height 172±5.98 cm, body fat percentage 10.93±3.39) participated in a separate session in the laboratory; their vvo2max was determined and then ...

The effect of ethanol on the interrelationship of lactate and glucose metabolism was investigated in eight human volunteers. Lactate and glucose kinetics and intervconversion rates were determined by the sequential administration of L-(+) lactate-U-(14)C and glucose-1-(14)C over an 8 hr period. After a 12 hr fast, the glucose turnover and recycling rates were 94.0 +/-3.8 (SEM) and 13.7 +/-1.1 m...

The effectiveness of bacteriophage P100, nisin and sodium lactate, individually and in combination, in inhibiting Listeria monocytogenes in ready-to-eat pork ham slices was assessed. The antimicrobials were applied to the surfaces of ready-to-eat pork ham slices, which were inoculated with a mixture of L. monocytogenes. Among the individual antimicrobial treatments, bacteriophage P100 was the m...

The purpose of the present study was to compare heart rate (HR), blood lactate and training load between different CrossFit® workouts, with equalized total work volumes in men women. included 23 individuals (13 10 women) experienced training, who performed two workouts types (as many reps as possible (AMRAP) ‘for time’) but an volume. Measurements lactate, HR rating perceived exertion (RPE) wer...

purpose to verify whether active recovery (ar) applied after a kickboxing match resulted in better performance in anaerobic tests when compared to passive recovery (pr). methods eighteen kickboxers volunteered to participate on a kickboxing match preceded and followed by anaerobic tests: squat jump (sj), the counter movement jump (cmj) and the upper-body wingate test. blood lactate (bl), heart ...

The anaerobic metabolism and its link with lactate and glycogen/glucose levels of muscles, liver and blood were quantitatively analyzed in tilapia, O. mossambicus under four different oxygen concentrations 5.20 + 0.65 (control), 3.66 + 0.55, 2.53 + 0.69 and 1.58 + 0.41 and recovery after 2 hrs (3.78 + 0.46) . The glycogen levels of muscle and liver reduced drastically at the oxygen level of 3.6...

conclusions comparing the serum lactate level before operation and 24 hours after the operation showed that the number of received blood units had a significant effect on serum lactate. we found no significant effect for blood storage duration; however, the number of given blood units was more significant. patients and methods in a cross-sectional study, 228 patients referred to three hospitals...

abstract: this research was done to determine the effect of using l-carnitine and selected exercises on aerobic capacity and blood lactate. in this study 30 unathletes students of shahid rajaee university took part with the age of 22/63±1/75, height: 176 cm, weight 71/33±1 and bmi: 23/17±2/6. subjects randomly divided into 3 groups, control group who were doing the selected exercises, experimen...
