When stressors that encourage this concentric hypertrophy are reduced or eliminated (either surgically corrected in the case of cardiac defects, or hypertension is reduced from diet and exercise) it is possible for the heart to undergo 'reverse remodeling', returning to a somewhat more 'normal' state instead of progressing to a dilated, pathologic phenotype. (wikipedia.org)
In general, rat swimming is considered one of the best physiological triggers for hypertrophy of the left ventricle and end-diastolic volume increase. (4science.ge)
3). Hypertrophy was observed only in rats of the experimental group (exercise load for 40 minutes with a load of 2% of body weight or exercise load for 60 minutes with a load of 4% of body weight). (4science.ge)
60 minutes of histological exercise load induced hypertrophy in 7 of 7 rats. (4science.ge)
ET-1 has potent positive inotropic and chronotropic effects on heart and induces myocardial cell hypertrophy. (elsevierpure.com)
The present results show that mRNA expression of ET-1 in the heart is increased by aging, and that the mRNA expression is further increased by exercise-induced cardiac hypertrophy, suggesting that ET-1 in the heart may participate in these physiological cardiac adaptations. (elsevierpure.com)
Athletes3
demonstrated that some highly trained, elite athletes who developed LVH primarily increased septal thickness, which exceeded normal values (females up to 13 mm, and males up to 16 mm). 5 An athlete with wall thickness between 12 and 16 mm represents the so called "grey zone" between the physiological adaptation of the athlete and pathologic expression of HCM. (acc.org)
Many clinicians who see athletes often prefer a CPX to standard treadmill exercise testing (TMET). (acc.org)
45 mm), while athletes with physiological LVH have concomitant enlargement of the left ventricular cavity. (acc.org)

We also investigated whether gene expression of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), which participate in some pathological cardiac conditions, in the rat hearts is altered by aging and subsequent exercise training. (elsevierpure.com)
Athlete's heart1
Cardiopulmonary exercise (CPX) testing is useful in differentiating athlete's heart from HCM. (acc.org)
Heart5
It is a response to 'volume-overload', either as a result of increased blood return to the heart during exercise, or a response to an actual increase in absolute blood volume as in pregnancy. (wikipedia.org)
The ratio of heart weight to body weight is proportional to the intensity of load and to the increase in the duration of exercise. (4science.ge)
R. Sherard (1969) proposed the following sub-maximal heart rate values for exercise samples by sex, weight and age, as recommended by the WHO Expert Committee. (chuflai.net)
It is the normal response to healthy exercise or pregnancy, which results in an increase in the heart's muscle mass and pumping ability. (wikipedia.org)

Adel Moussa, proprietor of Suppversity, has promulgated this view, especially the idea that antioxidants interfere with the response to exercise. (perfecthealthdiet.com)
1 Investigators in this field indicate that it takes approximately two years of intensive training of at least five hours per week to induce these adaptive changes, which are considered to be normal and are reversible with detraining. (acc.org)

Left1
Some experts feel that left ventricular cavity size is the single most important discriminator between physiological LVH and HCM. (acc.org)
High1
10 However, it should be noted that some HCM patients are able to exercise at a high level and, therefore, may be able to achieve VO 2 exceeding this level. (acc.org)
Bradycardia1
Senile bradycardia in individuals of both sexes can be physiological and can be observed after sleep, stress, and physical overstrain, but more often it is a symptom of ill-being. (netlify.app)
Cardiomyocyte3
We found that swimming-induced exercise increased cardiomyocyte proliferation and that this response was also found under regenerating conditions, when exercise was performed either prior to and after ventricular cryoinjury (CI). (frontiersin.org)
Taken together, our results suggest that exercise constitutes a physiological stimulus that may help promote cardiomyogenic mechanisms of the vertebrate heart through the induction of cardiomyocyte proliferation. (frontiersin.org)
These adaptations are related to how the cardiomyocyte contractile units, called sarcomeres, respond to stressors such as exercise or pathology. (wikipedia.org)
Cardiovascular5
Regular exercise initiates cardiovascular and respiratory changes in order to supply and deliver oxygen and nutrients to the working muscles and other tissues. (frontiersin.org)
Apart from the acute cardiac responses that are put in place to meet the increased energetic demands, exercise training provides a set of physiological responses suggested to be cardioprotective on the heart or the cardiovascular system. (frontiersin.org)

Among vertebrates, teleost fish hearts show a remarkable plasticity in response to environmental or physiological stressors, such as temperature, hypoxia, sexual maturation, diet, fish farming and exercise ( Gamperl, 2004 ). (frontiersin.org)
Pathological2
Moreover, as palpitations may be caused by a wide range of different physiological and pathological conditions, clinicians tend to apply a number of instrumental investigations, laboratory tests, and specialist examinations, which are both time-consuming and costly. (medscape.com)
