Effect of Ischemic Preconditioning on the Recovery of Cardiac Autonomic Control From Repeated Sprint Exercise

Frontiers in Physiology, 2018
Repeated sprint exercise (RSE) acutely impairs post-exercise heart rate (HR) recovery (HRR) and time-domain heart rate variability (i. e., RMSSD), likely in part, due to lactic acidosis-induced reduction of cardiac vagal reactivation.

The efficacy and physiological bases of small muscle mass exercise in health and disease

Experimental Physiology, EarlyView.
Abstract The conventional approach to aerobic exercise prescription involves large muscle mass exercise and the manipulation of variables such as training intensity, duration and frequency to promote desired adaptations. However, during whole‐body exercise, central limitations (i.e., neural, pulmonary and/or cardiac) constrain exercise tolerance and ...

Characteristics of power output during supramaximal cycle ergometer exercise in first- and third-grade male Japanese high school cyclists

Journal of Science and Cycling, 2020
Purpose: The purpose of this cross-sectional study was to clarify if there are differences in optimal load (Lopt; force factor), optimal cadence (Copt; velocity factor), and maximal anaerobic power (MAnP) between first- and third-grade high school ...

Combined multi‐metric assessment of diaphragm contractile function in healthy humans: Feasibility, validity and reliability

Experimental Physiology, EarlyView.
Abstract The combined use of subcostal ultrasonography and respiratory manometry represents a novel, integrative method for quantifying diaphragm contractile function (force, velocity and power). We evaluated the technical feasibility, construct validity and within‐day test–retest reliability of this method during non‐volitional, volitional and ...

Variability in heart rate recovery measurements over 1 year in healthy, middle-aged adults. [PDF]

, 2014
This study assessed the longer-term (12-month) variability in post-exercise heart rate recovery following a submaximal exercise test. Longitudinal data was analysed for 97 healthy middle-aged adults (74 male, 23 female) from 2 occasions, 12 months apart.

Mitochondrial haplotype and sex modulate responses to endurance exercise training

The Journal of Physiology, EarlyView.
Abstract figure legend Using OKC‐HETB/W rats we demonstrate that mitochondrial haplotype influences training responses of endurance exercise. Overall OKC‐HETW rats showed greater responses than OKC‐HETB in exercise tolerance, mitochondrial bioenergetics, mitochondrial DNA (mtDNA) mutation frequencies and motor co‐ordination.

β-alanine supplementation improves in-vivo fresh and fatigued skeletal muscle relaxation speed [PDF]

, 2017
Purpose: In fresh muscle, supplementation with the rate-limiting precursor of carnosine, β-alanine (BA), results in a decline in muscle half-relaxation time (HRT) potentially via alterations to calcium (Ca2+) handling. Accumulation of hydrogen cation (H+)

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Blood lactate clearance during active recovery after an intense running bout depends on the intensity of the active recovery [PDF]

, 2010
High-intensity exercise training contributes to the production and accumulation of blood lactate, which is cleared by active recovery. However, there is no commonly agreed intensity or mode for clearing accumulated blood lactate.

Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

The Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.
