The influence of physical exercise on the relation between the phase of cardiac cycle and shooting accuracy in biathlon

European Journal of Sport Science, 2018
This study examined the influence of physical exercise on the relation between shooting accuracy and the phase of the cardiac cycle in which the shot is fired.

Cardiac cycle gated cognitive-emotional control in superior frontal cortices

NeuroImage, 2020
Accumulating evidence suggests that peripheral physiological processes, such as the cardiac cycle, impact the individual's ability to appropriately exert control over behavior and emotional responses.

Taking Context to Heart: Momentary Emotions, Menstrual Cycle, and Cardiac Autonomic Regulation [PDF]

, 2019
Background. Emotions have long been discussed in conjunction with the autonomic nervous system. Most research on heart-mood linkages does not consider sex differences or an evident underlying mechanism for sex differences- sex hormone levels.

Mimicking the cardiac cycle in intact cardiomyocytes using diastolic and systolic force clamps; measuring power output

Cardiovascular Research, 2016
Aims A single isolated cardiomyocyte is the smallest functional unit of the heart. Yet, all single isolated cardiomyocyte experiments have been limited by the lack of proper methods that could reproduce a physiological cardiac cycle.

TIMING RELATIONSHIPS IN HUMAN CORTICAL PROCESSING [PDF]

, 1986
Although a number of studies have suggested that the phases of the alpha cycle and the cardiac cycle reflect temporal relationships in cortical processing, these studies are not conclusive.

Fully automated segmentation and tracking of the intima media thickness in ultrasound video sequences of the common carotid artery [PDF]

, 2013
—The robust identification and measurement of the intima media thickness (IMT) has a high clinical relevance because it represents one of the most precise predictors used in the assessment of potential future cardiovascular events.

MyoLoop: Design, development and validation of a standalone bioreactor for pathophysiological electromechanical in vitro cardiac studies

Experimental Physiology
Mechanical load is one of the main determinants of cardiac structure and function. Mechanical load is studied in vitro using cardiac preparations together with loading protocols (e.g., auxotonic, isometric).

Epigenetic regulation of cardiac myocyte differentiation

Frontiers in Genetics, 2014
Cardiac myocytes proliferate robustly during fetal life but withdraw permanently from the cell cycle soon after birth and undergo terminal differentiation.

Synchronizing Gait with Cardiac Cycle Phase Alters Heart Rate Response during Running

Medicine & Science in Sports & Exercise, 2017
Timing foot strike to occur in synchrony with cardiac diastole may reduce left ventricular afterload and promote coronary and skeletal muscle perfusion.
