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.

Cerebral Hemodynamic and Neurotrophic Factor Responses Are Dependent on the Type of Exercise

Frontiers in Physiology, 2021
This study examined acute cerebral hemodynamic and circulating neurotrophic factor responses to moderate intensity continuous exercise (MICT), guideline-based high intensity interval exercise (HIIT), and sprint interval exercise (SIT).

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.

The modified Borg cycle strength test (mBCST): Feasibility and physiological response in people with COPD and healthy older adults

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.

Acute effect of high-intensity interval training versus moderate-intensity continuous training on appetite-regulating gut hormones in healthy adults: A systematic review and meta-analysis

Heliyon, 2023
Background: Exercise intensity has been suggested to influence acute appetite-regulating gut hormone responses after exercise. High intensity interval training (HIIT) with near maximal to maximal intensity or sprint interval training (SIT) with ...

Commuting by bicycle (vs. by car) is associated with improved aerobic power, microvascular function and diminished CO2 output in the atmosphere

Experimental Physiology, EarlyView.
Abstract The study investigated whether bicycle compared with car commuting, over relatively small distances, has positive effects on physiological variables, cardiometabolic fitness and CO2 output in the atmosphere. Bike Commuters (11 M, 15 F; age [median value (interquartile range)] 51.5 (38.3–56.8) years; body mass index [BMI] 22.8 (21.0–24.1) kg m ...

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+)

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$
