Validity of Lactate Thresholds in Inline Speed Skating
Journal of Strength and Conditioning Research, 2015Lactate thresholds are commonly used as estimates of the highest workload where lactate production and elimination are in equilibrium (maximum lactate steady state [MLSS]). However, because of the high static load on propulsive muscles, lactate kinetics in inline speed skating may differ significantly from other endurance exercise modes. Therefore, the

Monitoring the lactate threshold in world-ranked swimmers
Medicine & Science in Sports & Exercise, 2001To determine whether lactate profiling could detect changes in discrete aspects of endurance fitness in world-ranked swimmers during a season.Eight male and four female Australian National Team swimmers aged 20--27 yr undertook a 7 x 200-m incremental swimming step test on four occasions over an 8-month period before the 1998 Commonwealth Games (CG ...

Alteration in the Lactate Threshold with Changes in Substrate Availability*
International Journal of Sports Medicine, 1981The lactate threshold (LT) was studied (N=9) during ergometer cycling under control (C), high blood glucose (G), and high blood free fatty acid (F) conditions. During the G trial blood lactate (HLa) was greater than C at all work loads (P less than 0.05) Adjusted blood HLa values (HLa - pre-exercise value = delta HLa), however, were essentially the ...

No effect of menstrual cycle phase on lactate threshold
Journal of Applied Physiology, 2003No previous exercise studies in women have assessed the effects of the normal menstrual cycle on the lactate threshold (LT) measured during a graded, maximal exercise test. This is relevant to our understanding of exercise training and metabolism in eumenorrheic women.

Reproducibility of Post-Exercise Lactate and Anaerobic Threshold
International Journal of Sports Medicine, 1988To test the effect of previous strenuous training on lactate (LA) formation and on changes of lactate threshold (AT) values, a group of seven male athletes aged 26.3 +/- 9.2 years, height 184 +/- 6.2 cm, body weight 79.3 +/- 8.1 kg, percentage of body fat 8.8 +/- 3.7 and VO2 max 56.2 +/- 5.4 ml/kg were examined on a treadmill to the maximum in the ...

The effects of prior exercise on the lactate and ventilatory thresholds
Journal of Sports Sciences, 1985This study examined the effects of prior exercise on the lactate (Tlac) and ventilatory (Tvent) thresholds. Ten healthy male subjects volunteered to perform one-legged cycling. Muscle glycogen reduction was achieved by cycling at 75-85% of maximal heart rate for 60-75 min, and by a low carbohydrate diet.

A New Approach for the Determination of Ventilatory and Lactate Thresholds
International Journal of Sports Medicine, 1992In order to determine the ventilatory threshold (VT) and the lactate threshold (LT) in a reliable way, a new method is proposed and compared with conventional methods. The new method consists of calculating the point that yields the maximal distance from a curve representing ventilatory and metabolic variables as a function of oxygen uptake (VO2) to ...

Aerobic exercise, anaerobic exercise and the lactate threshold
British Medical Bulletin, 1992All exercise draws first on intramuscular stores of ATP and creatine phosphate; initially these are replenished by anaerobic glycolysis. The lactic acid produced contributes to the rapid development of fatigue in high intensity exercise. Aerobic metabolism (at first mainly of glycogen, later increasingly of fat) is the principal route of ATP ...

Estimation of Lactate Threshold by Near Infrared Spectroscopy
1999The anaerobic or lactate threshold (LT) is defined as the point at which blood lactate levels rise significantly above basal levels and correlates with athletic performance in endurance events (Weltman, 1995). Currently gas exchange measurements of whole body VO2 and VCO2 are the best non-invasive techniques of measuring the LT (Beaver et al., 1986 ...
