Re-esterified DHA improves ventilatory threshold 2 in competitive amateur cyclists [PDF]

Journal of the International Society of Sports Nutrition, 2020
Background Fish oils were studied as ergogenic aids in a number of mixed physical trial designs showing promising results. However, the heterogeneous purity of the studied supplements, combined with the variety of physical tests employed call for more ...

Red Spinach Extract Increases Ventilatory Threshold during Graded Exercise Testing [PDF]

Sports, 2017
Background: We examined the acute effect of a red spinach extract (RSE) (1000 mg dose; ~90 mg nitrate (NO 3 − )) on performance markers during graded exercise testing (GXT).

Unlocking high-intensity performance thresholds through ventilatory signatures in the ECG [PDF]

Scientific Reports
A ubiquitously available and accurate non-invasive ventilatory threshold assessment (NIVA) would substantially improve real-world performance assessment evaluation in both clinical and elite sports settings.

Oxygenation Threshold Derived from Near-Infrared Spectroscopy: Reliability and Its Relationship with the First Ventilatory Threshold. [PDF]

PLoS ONE, 2016
BACKGROUND:Near-infrared spectroscopy (NIRS) measurements of oxygenation reflect O2 delivery and utilization in exercising muscle and may improve detection of a critical exercise threshold.

Peak Oxygen Uptake Prediction From Resting and Submaximal Variables of Cardiopulmonary Exercise Testing [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Cardiorespiratory fitness, as measured by peak oxygen uptake during cardiopulmonary exercise testing, is a prognostic indicator. We aim to predict peak oxygen uptake from submaximal variables on cardiopulmonary exercise testing to assess ...

Surface Electromyography Thresholds as a Measure for Performance Fatigability During Incremental Cycling in Patients With Neuromuscular Disorders

Frontiers in Physiology, 2022
In healthy persons, there is an excellent relation between the timing of the (two) surface electromyography (sEMG) thresholds and the (two) ventilatory thresholds during exercise. The primary aim of this study was to determine the relative timing of both

Six-minute rowing test: a practical tool for training prescription, from ventilatory thresholds and power outputs, in amateur male rowers [PDF]

PeerJ, 2023
Background The 6-minute rowing ergometer test (6-minRT) is valid and reliable for establishing maximal aerobic power (MAP) in amateur male rowers. However, ventilatory thresholds (VTs) have not yet been established with their mechanical correspondence in

Plasma free metanephrine and normethanephrine levels correlated to plasma catecholamine after acute running in amateur runner

Journal of Exercise Science & Fitness, 2021
Background/Objective: Catecholamine is a typical index of exercise intensity, but it is difficult to detect. Plasma metanephrine (MN) and normethanephrine (NMN) levels are more stable than those of catecholamines.

Partial-body cryostimulation procured performance and perceptual improvements in amateur middle-distance runners.

PLoS ONE, 2023
The purpose of this study was to investigate the effects of partial-body cryostimulation on middle-distance runners before two 3000-m tests at the speed of the first and second ventilatory threshold, and before a time to exhaustion test at 110% of the ...

CARDIORESPIRATORY FITNESS LEVEL INFLUENCES THE VENTILATORY THRESHOLD IDENTIFICATION

Journal of Physical Education, 2022
We aimed to analyze the influence of cardiorespiratory fitness (CRF) on ventilatory threshold identification (VT1) using the Ventilatory Equivalents (VEq) and V-slope methods.
