Blood lactate levels was measured before and 5 min. after each exercise session.

High blood lactate levels indicate a lack of oxygen delivered to working muscle.

Blood lactate levels were extremely high and remained significantly elevated for at least 8 h after exercise.

Blood lactate levels were unaffected by the drug and by the run to exhaustion.

Studies have also shown that blood lactate levels increase dramatically with circuit work, suggesting a high anaerobic content to the training.

The study examined heart rates, blood lactate levels, and ability to continue exercise for 12 professional soccer players after repeated bursts of intensive running.

Gaesser et al (1986) found that with 3 weeks of training, there were dramatic decreases in blood lactate levels during a constant load test.

The effects of reserpine upon skeletal muscle and blood lactate levels have been studied in exercised and control rats.

Future research will further correlate sweat lactate levels with fitness, performance and blood lactate levels, Wang added.

Physiologists from USA Swimming took a pinprick of his ear, routine at such meets for top swimmers, to measure his blood lactate level.

Throughout both exercise sessions, the researchers tracked a variety of physiological measures -- such as oxygen consumption, heart rate, cardiac output, blood pressure, ventilation and blood lactate levels.

Type III patients be distinguished by elevated liver enzymes, with normal uric acid and blood lactate levels, differing from other forms of GSD.

He made more use of science and technology in his running than many of his contemporaries, basing his training around heart rate and often having his blood lactate levels tested.

As it turned out, the athletes' oxygen consumption rates were nearly identical in the two cases, and heart and breathing rates, total rate of power production, and blood lactate levels were also similar.

A randomized controlled trial of DCA in adults with lactic acidosis found that while DCA lowered blood lactate levels, it had no clinical benefit and did not improve hemodynamics or survival.

Aerobic threshold occurs with a slight increase in blood lactate levels, while lactate threshold occurs with a large jump in blood lactate levels How often should you have it tested?

The "mighty mice" primarily relied on "fatty acids as a source of energy during exercise, while the control animals rapidly switched from fatty acid metabolism to using muscle glycogen (carbohydrates) as a fuel; this dramatically raised the blood lactate levels," the research said.

Phelps and other swimmers are continually tested to measure their blood lactate levels (the lower they are, the better a body’s state of aerobic conditioning) and to determine the rate at which they clear lactate from their systems, which indicates their ability to recover.

PANGAMIC ACID (VITAMIN B15, D15) Touted by many athletes as a performance enhancer (increased aerobic capacity, increased endurance, decreased blood lactate levels), there is no evidence from controlled studies as to any benefits in athletic performance.

Participation in eccentric training and conditioning, including resistance training and activities that emphasize eccentric lengthening of the muscle including downhill running on a moderate to high incline can result in considerable soreness within 24 to 48 hours, even though blood lactate levels, previously thought to cause muscle soreness, were much higher with level running.

In the presence of 5% CO2 (group H2), hypoxia was associated with a smaller rise in blood lactate levels than that seen in group H1, myocardial lactate concentration failed to rise above the high prehypoxic control levels, and the M/CS ratio fell although a significant gradient persisted during hypoxia.

However, blood lactate concentrations were greater in rats exposed to heat.

Blood lactate concentrations were also greater in the air-exposed fish and continued to increase throughout the experiment.

Elevated muscle and blood lactate concentrations are a natural consequence of any physical exertion.

It can also significantly improve muscle recovery following exercise by reducing the levels of blood lactate concentration.

To study this issue, we determined blood lactate concentrations after competitive sprint running in male and female master athletes of different age.

Mean blood lactate concentrations and percentage heart rate maximum at which the participants were working were not different between groups in any of the trials.

Another study showed that the meditators had significantly lower blood lactate concentration after physical exercise than the control group, indicating faster recovery.

Type 2B muscle fibres are only recruited during very strenuous exercise, when blood lactate concentrations may rise sharply.

Postcompetition blood lactate concentration in highly ranked Australian swimmers.

However, eight dogs with chronic metabolic acidosis had a spontaneous blood lactate concentration of 0.5 mM or lower.

Heart rate, blood lactate concentrations and estimated energy expenditure in a semi-professional rugby league team during match play: A case study.

In both groups, blood lactate concentrations were significantly lower in the endurance trial than in the sprint and resistance trials.

Active recovery reduces blood lactate concentration, but does not affect performance on a 50 m sprint when 6 min recovery is provided.

Active recovery reduces blood lactate concentration faster than passive recovery and, when the proper intensity is applied, a positive effect on performance is expected.

In contrast, the anaerobic energy yield (oxygen deficit and peak blood lactate concentrations) was similar in all HITs.

The scientists also looked at how much oxygen they consumed before and after exercise, and blood lactate concentrations before and after exercise.

The aerobic threshold (AeT or AerT) is sometimes defined as the exercise intensity at which blood lactate concentrations rise above resting levels.

The blood lactate concentration was significantly elevated in thiamine-deficient (TD) animals when compared with pair-fed (TP) controls.

The blood lactate concentration at the anaerobic threshold is called the "maximum steady-state lactate concentration" (MLSS).

Until now, an ADL has been determined empirically from measurements of blood lactate concentration only in the Weddell seal, Leptonychotes weddellii.

After the swim test, F90° and mean power frequencies of the EMG decreased significantly when blood lactate concentration increased significantly, attesting the reaching of fatigue.

At the higher exercise intensities with the longest durations O2 deficit, blood lactate concentration, and excess CO2 estimates of anaerobic and total energy expenditure revealed high variability; however, they were not statistically different.

If blood lactate concentration takes approximately 10 minutes to reach steady state then how can a test that involves several intervals of around 2 to 2.5 minutes shed light on a maximum lactate steady state value?

The short test induced higher mechanical ventilatory constraints and dyspneic feeling than the long protocol, which could be explained by a higher E itself linked to a greater CO2 and a higher blood lactate concentration.

Isometric arm flexion force with the elbow at 90° (F90°), EMG signals of right musculus biceps brachii and triceps brachii and blood lactate concentrations were recorded before and after the swim test.
