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.

Cross-Modal Video to Body-joints Augmentation for Rehabilitation Exercise Quality Assessment [PDF]

arXiv, 2023
Exercise-based rehabilitation programs have been shown to enhance quality of life and reduce mortality and rehospitalizations. AI-driven virtual rehabilitation programs enable patients to complete exercises independently at home while AI algorithms can analyze exercise data to provide feedback to patients and report their progress to clinicians.

Direct Stimulation of Gastric Smooth Muscle Cells via Gq Proteins With Light

Neurogastroenterology &Motility, EarlyView.
Optogenetic stimulation enables direct and selective stimulation of smooth muscle cells and thus provides a new opportunity to restore gastric contractility in cases of gastroparesis. Herein, we demonstrate that hOPN5 is a new and effective tool acting via Gq signaling and is thus complementary to light‐induced membrane depolarization with ...

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.

'Muscular wisdom' revisited: Decaying rates of stimulation mitigate torque loss. [PDF]

Exp Physiol
Abstract During a sustained high‐intensity isometric maximal voluntary contraction (MVC), declining motor unit firing rates (MUFRs) accompany torque loss. This decline (∼50% over 60 s) helps to maintain torque by preserving peripheral electrical propagation and matching the slowing contractile properties with torque loss (i.e., ‘muscular wisdom ...

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).

Rehabilitation Exercise Quality Assessment through Supervised Contrastive Learning with Hard and Soft Negatives [PDF]

Medical & Biological Engineering & Computing Journal, 2024
Exercise-based rehabilitation programs have proven to be effective in enhancing the quality of life and reducing mortality and rehospitalization rates. AI-driven virtual rehabilitation, which allows patients to independently complete exercises at home, utilizes AI algorithms to analyze exercise data, providing feedback to patients and updating ...
