Muscle Fatigue at the End of a Maximal Oxygen Consumption Test
… (MF) were extracted and normalized using the maximal voluntary contraction (MVC) from the selected sEMG samples. MATLAB was used in order to observe the tendencies over time for the left and right rectus femoris, vastus medialis and vastus lateralis. Force production applied to the pedals was …

Effects of a single-leg exercise training intervention on single and double leg peak power output, maximal oxygen consumption, gas exchange threshold, and the respiratory compensation point
… leading to significant increases in double-leg maximal oxygen consumption, the gas exchange threshold and respiratory compensation point.

A comparative analysis of the heart rate-oxygen consumption relationship observed during Bruce protocol graded exercise stress tests and steady-state exercise
… were studied to determine whether the heart rate-oxygen consumption relationships observed during Bruce protocol stress tests were similar to those observed during steady-state exercise. In addition, maximal oxygen consumption and maximal heart rate values obtained during the stress tests were …

Beyond the VO2max plateau a new approach for measuring maximal oxygen uptake
Maximal oxygen consumption (VO2max) is typically defined by the presence of the "plateau phenomenon" during incremental exercise tests, in which O2 consumption levels-off in spite of increases in workload. This is thought to reflect a limitation in the capacity of the heart to pump O2 enriched …

Causal Machine Learning to Discover Biochemical Determinants of Physical Fitness
… and their impact on changes in individuals’ maximal oxygen consumption (a proxy for physical fitness).

Accelerometer Measured Physical Activity and Obesity
… relative intensity of PA after accounting for maximal oxygen consumption by sex and body mass index categories in 828 adults. These results suggest that the established accelerometer thresholds may bias measures of objective PA for individuals with obesity and this may contribute to the …

Effect of glycerol hyperhydration before exercise in trained triathletes on endurance performance and cardiovascular and thermoregulatory responses
… then performed 2 h of cycling at 65% of maximal oxygen consumption (VO[subscript 2] max), which was immediately followed by an endurance performance test to exhaustion. All trials were conducted at 25[degrees Celsius], 38-42% relative humidity (RH). During exercise, subjects consumed a 6% …

The Impact of Interval Intensity in Overweight Young Men
… groups and understanding the influence of both oxygen supply and demand in determining maximal oxygen consumption, the greater increases in aerobic capacity achieved by the 100% group may be the result of enhanced cardiovascular adaptations. These findings suggest that some of the health …

Limits to exogenous glucose oxidation by skeletal muscle during prolonged, moderate-intensity exercise in man
… cycling at a work rate of 63% of PPO (~70% of maximal oxygen consumption [VO₂ₘₐₓ]).

Exertion therapy for the mentally subnormal child.
… at rest, heart rate at sub minimal workload and maximal oxygen consumption rate estimates served as measures of physical fitness. Changes in intellectual and social functioning were assessed by means of the Vineland Social Maturity Scale, Old South African Individual Scale, and Goodenough …

Building a Low-Cost Portable VO2 Max Mask
Maximal oxygen consumption more commonly known as VO₂ max is the gold standard indicator of cardiorespiratory fitness and a stronger predictor of all-cause mortality than traditional health risk factors such as smoking, diabetes, and hypertension. Despite being recognized as a clinical vital metric …

The Reliability and Validity of the 30-15 Intermittent Field Test with a Ball
… separated by a minimum of 48 hours. Maximal intermittent running velocity (VIFT), heart rate at exhaustion (HRpeak), and rating of perceived exertion (RPE) were collected. Interclass correlation coefficients (ICCs) demonstrated good reliability during the 30-15IFT in VIFT (ICC = 0.88) …

Effects of Aerobic Exercise on Cognitive and Cerebrovascular Function in Hypertensive Adults
… pre and post 30-min of aerobic exercise at ≈55% maximal oxygen consumption. Arterial stiffness and cerebral hemodynamics were measured non-invasively. Cognitive function was measured using a computerized testing battery that included executive function and memory tasks. Acute aerobic exercise …

The effect of boron supplementation and oral contraceptives on mineral status and hormone status of college female athletes and non-atheletes
… a placebo or 3 mg of boron per day. Subjects' maximal oxygen consumption (VO₂max) was assessed as a baseline measurement and was used to confirm a difference between activity groups. Body fat, height, bone mineral density, and serum calcitonin and parathyroid also were baseline measurements. …

Estimation of stability reliability for determination of peak VO₂ in young adults on an inclined stepper and treadmill
… graded, step (SI, SII) ergometry tests to assess maximal oxygen consumption (V̇O₂max). The order of these tests was randomized. Expired gases were analyzed using the Medical Graphics CPX/D metabolic cart. V̇O₂max between SI (V̇O₂ = 2.57 L/min) and SII (V̇O₂ = 2.65 L/min) revealed an correlation of …
