Systemic blockade of ACVR2B ligands attenuates muscle wasting in ischemic heart failure without compromising cardiac function

2020

Signaling through activin receptors regulates skeletal muscle mass and activin receptor 2B (ACVR2B) ligands are also suggested to participate in myocardial infarction (MI) pathology in the heart. In this study, we determined the effect of systemic blockade of ACVR2B ligands on cardiac function in experimental MI, and defined its efficacy to revert muscle wasting in ischemic heart failure (HF). Mice were treated with soluble ACVR2B decoy receptor (ACVR2B-Fc) to study its effect on post-MI cardiac remodeling and on later HF. Cardiac function was determined with echocardiography, and myocardium analyzed with histological and biochemical methods for hypertrophy and fibrosis. Pharmacological blo…

Resting electrocardiogram and blood pressure in young athletes and nonathletes : A 4-year follow-up

2022

A follow-up data on electrocardiogram (ECG) and blood pressure (BP) changes in adolescent athletes are scarce. We compared ECG and BP between adolescent athletes and non-athletes in a 4-year follow-up. A total of 154 youth sports clubs (SC) in Finland and 100 secondary schools for comparison data participated in this observational follow-up study. Those who maintained or adopted SC participation are referred to as “Always athletes” (n=137), those who never participated in SC as “Never athletes” (n=108) and those who dropped out of SC during the follow-up as “Changers” (n=116). The mean age of the participants was 15.5 (0.6) years in all study groups at baseline. Resting ECG including heart …

Different-day and same-session combined strength and endurance training : adaptations in neuromuscular and cardiorespiratory performance, body compos…

2017

This thesis investigated 1) acute neuromuscular and hormonal responses to combined strength and endurance loadings with different orders and their long-term adaptations (women), 2) adaptations in neuromuscular, hormonal, cardiorespiratory and health variables following 24 weeks of volume-equated protocols of combined training (men and women). Subjects were assigned to one of three groups: strength and endurance training on different days (DD: men n=21, women n=18), training in the same-session with either endurance before strength (ES: men n=16, women n=15) or vice versa (SE: men n=18, women n=14). DD trained 4-6 d·wk-1 with strength and endurance on alternating days. ES and SE trained 2-3 …

Maratonjuoksun vaikutukset sydänlihaksen verenvirtaukseen, pumppaustehokkuuteen ja mahdolliseen sydänlihasvaurioon kestävyysurheilijoilla

Marko Laaksonen. Maratonjuoksun vaikutukset sydänlihaksen verenvirtaukseen, pumppaustehokkuuteen ja mahdolliseen sydänlihasvaurioon kestävyysurheilijoilla. Liikuntafysiologian Pro Gradu -tutkielma. Liikuntabiologian laitos. Jyväskylän yliopisto. Fyysisellä aktiivisuudella on todettu olevan monia positiivisia vaikutuksia hengitys- ja verenkierto elimistön toimintaan sekä terveyteen yleensä. Kuitenkin pitkiin urheilusuorituksiin liittyy suurentunut riski sydämen toimintahäiriöön ja jopa yllättävään kuolemaan. Monissa ultraäänitutkimuksissa onkin todettu sydämen pumppaustoiminnan heikentyneen pitkäkestoisen intensiivisen suorituksen jälkeen. Lisäksi on olemassa monia tutkimuksia, joissa on esi…

Behavioral Inhibition Underlies the Link Between Interoceptive Sensitivity and Anxiety-Related Temperamental Traits

2017

Interoceptive sensitivity is a biologically determined, constitutional trait of an individual. High interoceptive sensitivity has been often associated with proneness to anxiety. This association has been explained by elevated autonomic responsiveness in anxious individuals. However, in a heartbeat discrimination task (discrimination of heartbeats’ simultaneity to an external stimulus) low cardiac responsiveness has accompanied enhanced performance. The relation between these factors seems task dependent, and cannot comprehensively explain the link between interoceptive sensitivity and anxiety. We explored for additional explanatory factors for this link. More specifically, we studied which…

Association between resting blood pressure and maximal blood pressure response to exercise and arterial health

2022

We investigated the longitudinal associations of blood pressure, cardiorespiratory fitness, and arterial stiffness among children. Arterial stiffening has been repeatedly shown to be a cardiovascular mortality predictor and can be observed early in childhood. As such, it is crucial to understand whether a child’s blood pressure, fitness level, and body composition can predict early signs of atherosclerosis and arterial stiffening. The current study examined the relationship between blood pressure, cardiorespiratory fitness, and arterial stiffness over time in children, using data from the Physical and Nutrition in Children (PANIC) Study. It is a physical and dietary intervention study condu…

Habitual physical activity and heart rate variability in 12-year old children

2012

ABSTRACT Wennman, Heini 2012. Habitual physical activity and heart rate variability in 12-year old children. Department of Biology of Physical Activity, University of Jyväskylä, 92p. The study of heart rate variability (HRV) provides useful information about the function of the cardiac autonomic nervous system. The effects of many environmental factors on HRV are well known, but the associations between physical activity (PA) and HRV, especially in children, are less investigated. Higher HRV is related to health and many pathologic conditions are associated with reduced HRV. Exercise causes HRV to diminish, but improves HRV in long term. PA promotes many health related changes in energy met…
