The lactate and ventilatory thresholds in resistance training

Clinical Physiology and Functional Imaging, 2016
SummaryPurposeThis study was designed to identify the lactate threshold (LT) and first ventilatory threshold (VT1) in a graded resistance half‐squat test and determine whether both thresholds are produced at the same workload. A further goal was to compare the visual inspection and algorithm adjustment methods of detecting both thresholds during graded

A Comparison of Methods for Estimating the Lactate Threshold

The Journal of Strength and Conditioning Research, 2005
The purpose of this study was to examine the accuracy of tests that may be used by distance runners to estimate the lactate threshold. Competitive distance runners/triathletes (N = 27) performed a criterion test that directly measured (blood lactate of 4.0 mmol.L(-1)) the lactate threshold.

Respiratory Rate Threshold Accurately Estimates the Second Lactate Threshold

International Journal of Sports Medicine, 2018
Abstract Purpose The modified Dmax method can accurately determine the second lactate threshold (LT2), which is valuable for predicting aerobic performance and prescribing exercise. The purpose of this study is to determine if the modified Dmax method can accurately find thresholds in VE (VT2), VCO2 (VCO2T), RER (RERT), and RR (RRT) to estimate LT2 ...

Lactate and ventilatory thresholds: disparity in time course of adaptations to training

Journal of Applied Physiology, 1985
We tested the hypothesis that the lactate threshold (Tlac) during incremental exercise could be increased significantly during the first 3 wk of endurance training without any concomitant change in the ventilatory threshold (Tvent). Tvent is defined as O2 uptake (VO2) at which ventilatory equivalent for O2 [expired ventilation per VO2 (VE/VO2 ...

Validity of a single lactate measure to predict fixed lactate thresholds in athletes

Journal of Sports Sciences, 2016
This study aimed to validate the use of a single blood lactate concentration measure taken following a 12 km h-1 running stage (BLC12) to predict and monitor fixed blood lactate concentration (FBLC) thresholds. Three complementary studies were undertaken. Study I: the relationships between BLC12 and the running speeds at FBLC of 3 mmol L-1 (S3mM) and 4

Critical Velocity and Lactate Threshold in Young Swimmers

International Journal of Sports Medicine, 2006
The purpose of the present study was to compare the critical swimming velocity (CV) in children, with the lactate threshold (LT) and the velocity corresponding to a blood lactate concentration of 4 mmol x l(-1) (V4). Twenty swimmers (ten females and ten males, mean +/- SD age: 12.9 +/- 1.1 years, body weight: 51.2 +/- 10.0 kg, height: 157.1 +/- 9.7 cm)

Comparison of three methods for detection of the lactate threshold

Clinical Physiology and Functional Imaging, 2007
SummaryThe lactate threshold (LT) represents the onset of a metabolic acidosis during graded exercise testing (GXT). It is a valuable measurement in clinical exercise testing and correlates well with endurance performance. Our purpose was to compare three LT detection methods, namely, Inspection (work rate at onset of a systematic increase in blood ...

Validity of Lactate Thresholds in Inline Speed Skating

Journal of Strength and Conditioning Research, 2015
Lactate 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, 2001
To 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 ...

The concept of lactate threshold. A short review.

The Journal of sports medicine and physical fitness, 1995
The anaerobic threshold (AT) is a widely used tool for investigating aerobic performance characteristics in physiological of pathological conditions. The aim of the present paper is to show that, when the lactate concentration in blood [Lab] is constant in time, regardless of its absolute level, the whole body energy sources for muscular work are ...
