Blood lactate levels during exercise : the effects of exercise duration, bicarbonate infusion and beta-receptor antagonism
This study examines factors that determine blood lactate accumulation during exercise in order to examine the opposing theories that such accumulation occurs either as a result of muscle anaerobiosis or an "overflow" of oxygen-independent glycolysis.

Physiological responses, perceptual responses and target heart rate compliance of coronary heart disease patients during walk-jog exercise
… exertion (RPE<sub>C</sub>) and post-exercise lactate accumulation (La) during exercise which was held constant between 60-80% maximum HR reserve were also made. Procedures consisted of three 20 min walk-jog exercise conditions. First, two baseline condition (BC) trials were performed on …

RPE "Drift" in Fit and Unfit Males Cycling in a Hot and Cool Environment
… for 60min (intensity~90% of the Onset of Blood Lactate Accumulation (OBLA) - determined via gas exchange indices) at 30}1 degrees Wet Bulb Globe Temperature (WBGT) and 18}1 degrees WBGT. Heart rate (HR), rectal temperature (Tree) and overall and differentiated RPE estimations were collected …

Aerobic exercise training for patients suffering from intermittent claudication
… the effects of walking exercise on serum lactate accumulation (HLa, mmol⁻¹), ankle pressure index (API), total treadmill time (sec), and onset of leg pain (sec) in the most severely diseased limb. Subjects were evaluated via a functional walking tolerance test before participation in a …

Effects of aerobic exercise and weight reduction on carbohydrate metabolism during submaximal exercise in sedentary, overweight women
… Whole blood was immediately analyzed for lactate accumulation. The remaining blood was centrifuged, separated, and frozen for subsequent serum glucose, cortisol, and insulin measurement. There was a significant increase in oxygen uptake (ml/kg/min), and a decrease in body weight, ( 6.7%), …

Muscle glycogenolysis during weight-resistance exercise
… 1.0 and 12.4 ± 0.5). After the sixth set, muscle lactate accumulation was also similar (13.8 ± 0.7 and 16.7 ± 4.2 mmol•kg-1 wet wt for HI and LO trials, respectively). After two hours of passive recovery with no feedings, muscle glycogen storage during the HI and LO trials was 22.2 (±6.8) and 14.2 …

Effects of Hyperoxia on Thermal Tolerance and Indicators of Hypoxic Stress in Antarctic Fishes That Differ in Expression of Oxygen-Binding Proteins
… limitation (hypoxia inducible factor-1α and lactate) would increase to a greater extent in icefishes compared to red-blooded fishes and that this increase would be minimized under hyperoxic conditions. I sampled <i>Chaenocephalus aceratus</i> (Hb-) and <i>Notothenia coriiceps</i> (Hb+) at …

Comparison of Power Output Between Rotor and Normal Cranks During a 16.1 KM Time Trial
… performance (e.g. peak power output, VO2max, lactate threshold, onset of blood lactate accumulation, economy, delta, and gross efficiency) under laboratory conditions. However, previous research has not attempted to determine whether the use of the Rotor cranks can improve sustainable power …

The effects of dosing feedlot cattle with Megasphaera elsdenii strain NCIMB 41125 prior to the introduction of a grain-rich diet
… populations, and determine in vitro capacity for lactate utilization following intraruminal dosing of a placebo or [italic]M. [italic]elsdenii strain NCIMB 41125 and an abrupt diet change. Angus crossbred steers (n=20; average BW=253 ± 24 kg) fitted with ruminal cannulas were blocked by BW and …

The Longitudinal Effects of Beta-Alanine on Punch Power, Punch Frequency, and Fatigue in Female Amateur Fighters
… increased punch power, punch frequency, and lactate concentrations in male amateur fighters after 28-day supplementation. There are currently no studies evaluating the effects of BA on boxing performance variables in women. Therefore, the purpose of this study was to examine the longitudinal …

The Ventilatory Threshold and Maximal Steady-State Exercise in Patients with Coronary Artery Disease
… threshold (VT) correlates highly with onset of lactate accumulation and maximal steady-state exercise (MSS) level. Also, studies have shown the VT is useful in prescribing exercise for cardiac patients in that it gives an exercise intensity at which the patient is metabolically stable. METHODS: …

Zur Bedeutung der maximalen Laktatbildungsrate in Diagnostik und Training am Beispiel Skilanglauf und Radsport
Die Arbeit beleuchtet die Bedeutung der maximalen Laktatbildungsrate (V̇Lamax) für die Leistungsdiagnostik und die Trainingspraxis. Für die Sportart Skilanglauf wurde ein neuer Sprinttest zur Bestimmung der V̇Lamax am Skiergometer entwickelt, der sich als reliabel und valide erwiesen hat. Dabei …
