Oxygen uptake kinetics during supra-maximal exercise: Mathematical modelling

Revista Brasileira de Cineantropometria e Desempenho Humano, 2008
Precise estimation of oxygen uptake kinetics parameters is essential to understand its control and/or limit uptake mechanisms. The purpose of the present study was to characterize the oxygen uptake kinetics responses during supramaximal cycle ergometer ...

The influence of acute variable resistance loading on subsequent free-weight maximal squat performance [PDF]

, 2013
Elastic bands attached to a loaded barbell during a squat exercise create a variable resistance (VR), thus changing the mechanical loading and stress placed through the musculoskeletal system.

Different types of exercise and myocardial angiogenesis regulation: A scoping review of cardiac‐specific evidence in animal models

Physiological Reports, Volume 14, Issue 5, March 2026.
Abstract Exercise promotes myocardial angiogenesis, yet molecular responses vary by modality, and cardiac‐specific evidence in healthy models remains fragmented. This study aimed to map biomolecular regulators of myocardial/coronary angiogenesis across exercise types in healthy animal models. PRISMA‐ScR scoping review.

Stroke increases motor output variability during maximal voluntary isometric contractions of knee extensor muscles in adults

Physiological Reports, Volume 14, Issue 6, March 2026.
Compared with neurotypical controls, stroke survivors had greater motor output variability (inconsistency and unsteadiness) during a single session of maximal voluntary isometric contractions of the paretic knee extensor muscles, highlighting the importance of using multiple attempts when assessing maximal muscle strength in stroke survivors.

Static loads on the lower back for two modalities of the isometric smith squat [PDF]

, 2014
Introduction: The squat is one of the most effective exercises in athletic training. However, there is a scarcity of research that reports the muscular and joint loads in the lumbar region incurred when performing the high bar and the low bar isometric ...

Voluntary Activation and Variability During Maximal Dynamic Contractions with Aging [PDF]

, 2017
Whether reduced supraspinal activation contributes to age-related reductions in maximal torque during dynamic contractions is not known. The purpose was to determine whether there are age differences in voluntary activation and its variability when ...

Cardiac damage biomarkers and heart rate variability following a 118-km mountain race: relationship with performance and recovery [PDF]

, 2019
This study aimed to assess the release of cardiac damage biomarkers jointly with cardiac autonomic modulation after a mountain ultramarathon. Such knowledge and the possible relationship of these markers with race time is of primary interest to establish

Multimodal assessment of exercise-induced fatigue: integrating cardiopulmonary, neuromuscular, and biomechanical profiling in high-intensity running

Frontiers in Sports and Active Living
This study aimed to establish a multimodal framework integrating cardiopulmonary exercise testing (CPET), surface electromyography (sEMG), and plantar kinetic assessment to characterize neuromuscular and mechanical fatigue responses during high-intensity

Utilization of the graded universal testing system to increase the efficiency for assessing aerobic and anaerobic capacity [PDF]

The in-flight exercise test performed by cosmonauts as part of the Russian Exercise Countermeasure Program is limited to 5 minutes due to communication restrictions. During a recent graded exercise test on a U.S.

EFFECT OF MUSIC ON ANAEROBIC EXERCISE PERFORMANCE

Biology of Sport, 2013
For years, mostly the effects of music on cardiorespiratory exercise performance have been studied, but a few studies have examined the effect of music on anaerobic exercise.
