Effects of Low Cell pH and Elevated Inorganic Phosphate on the pCa-Force Relationship in Single Muscle Fibers at Near-Physiological Temperatures [PDF]
, 2014 Intense muscle contraction induces high rates of ATP hydrolysis with resulting increases in Pi, H+, and ADP, factors thought to induce fatigue by interfering with steps in the cross-bridge cycle.

The metalloproteinase ADAM17 promotes acute lung inflammatory responses during pancreatitis
British Journal of Pharmacology, EarlyView.Background and Purpose Acute pancreatitis (AP) is a multifactorial upper gastrointestinal inflammatory disorder that in severe cases (~20% of all AP) is associated with substantial morbidity and mortality, the latter coincident with multiorgan dysfunction, particularly acute lung injury (ALI).

Validity of the maximum oxygen deficit accumulated as an index of the anaerobic capacity
European Journal of Human Movement, 2010 To assess the validity of the maximal accumulated oxygen deficit (MAOD) as a measure of the anaerobic capacity, the following variables were determined in twenty nine male Physical Education students: the DMOA, the blood lactate concentration at the end ...

EFFECT OF ACUTE HYPOXIA ON POST-EXERCISE PARASYMPATHETIC REACTIVATION IN HEALTHY MEN
Frontiers in Physiology, 2012 In this study we assessed the effect of acute hypoxia on post-exercise parasympathetic reactivation inferred from heart rate (HR) recovery (HRR) and HR variability (HRV) indices. Ten healthy males participated in this study.

Effects of exercise-induced arterial hypoxemia on limb muscle fatigue and performance [PDF]
, 2006 1. Reductions in arterial O2 saturation (−5% to −10% SaO2 below rest) occur over time during sustained heavy-intensity exercise in a normoxic environment, caused primarily by the effects of acid pH and increased temperature on the position of the ...

Sex Differences in Mechanisms of Recovery after Isometric and Dynamic Fatiguing Tasks [PDF]
, 2018 Purpose The purpose of this study was to determine whether supraspinal mechanisms contribute to the sex difference in fatigability during and recovery from a dynamic and isometric fatiguing task with the knee extensors.

Experimental Physiology, EarlyView.Abstract Accurate prescription of supramaximal exercise requires exercise tests covering the intensity domain between maximal aerobic and peak power output. All‐out tests are commonly used for this objective but are considered challenging for people with chronic obstructive pulmonary disease (COPD) due to the extreme physiological demand.

Current aspects of high-intensity interval training for older adults: a narrative review
Journal of Physical Fitness and Sports Medicine, 2022 Negative aspects of aging include a decrease in muscle mass/strength and maximal oxygen consumption (VO2max). The most beneficial and adaptable protocol among the various exercise methods should be explored in older adults.
