Physical activity (PA) and exercise training (ET) are central and indispensable components for primary and secondary prevention of cardiovascular disease (CVD). In healthy individuals, PA reduces all-cause and CV mortality and has confirmed beneficial effects on the cardiovascular risk profile. In secondary prevention, PA counselling und ET are two of the core components of a multidisciplinary cardiac rehabilitation (CR) program. Exercise-based CR is an established strategy in the secondary prevention of CV disease. It improves survival, reduces hospital admissions, improves cardiorespiratory fitness (CRF), and quality of life (QoL). However, these beneficial effects require regular attendance under professional supervision and adherence to recommended guidelines. In patients with heart disease, proper patient assessment with a standardized exercise test as a basis for a tailored ET prescription is required. In healthy subjects this is advocated only in selected groups. Current guidelines recommend at least 150 min/week of moderate-intensity continuous aerobic PA in both healthy individuals as well as those with cardiac disease. In healthy adults, alternatively intensity can be increased and volume can be halved. High intensity interval training (HIIT) is a relatively new training modality and may be used complementary to continuous training in selected patient groups. HIIT seems to be superior compared to moderate continuous exercise in patients with cardio metabolic disease with regard to effects on the CV risk profile, endothelial function, improvement in cardiorespiratory fitness, and a reverse cardiac remodelling in patients with heart failure. One of the major challenges in preventive cardiology is the improvement of long-term adherence to PA recommendations. The aim of this article is to give an overview from the preventive cardiologist’s point of view with a focus on endurance ET prescription for the audience of sports and exercise medicine physicians.

AbstractThe benefits of regular physical activity whether in primary- or secondary prevention of cardiovascular disease are now irrefutable. Despite its well proven benefits, exercise training remains underused because of lack of insight and familiarity of the majority of cardiologists. This review offers cardiologists the necessary informations about the pathophysiological mechanisms, effects and limitations of the predominantly used training methods in various kardiovascular diseases.

Background:Individuals may compensate for exercise training by modifying nonexercise behavior (ie, increase sedentary time (ST) and decrease nonexercise physical activity [NEPA]).Purpose:To compare ST and NEPA during a 12-week exercise training and/or lifestyle intervention.Methods:Fifty-seven overweight/obese participants (19 M/39 F) completed the study (mean ± SD; age 43.6 ± 9.9 y, BMI 35.1 ± 4.6 kg/m2). There were no between-group differences in activity levels at baseline. Four-arm quasi-experimental intervention study 1) EX: exercise 5 days per week at a moderate intensity (40% to 65% VO2peak) 2) rST: reduce ST and increase NEPA, 3) EX-rST: combination of EX and rST and 4) CON: maintain habitual behavior.Results:For the EX group, ST did not decrease significantly (mean ((95% confidence interval) 0.48 (–2.2 to 3.1)% and there was no changes in NEPA at week-12 compared with baseline. The changes were variable, with approximately 50% of participants increasing ST and decreasing NEPA. The rST group decreased ST (–4.8 (0.8 to 7.9)% and increased NEPA. EX-rST significantly decreased ST (–5.1 (–2.2 to 7.9)% and increased time in NEPA at week-12 compared with baseline. The control group increased ST by 4.3 (0.8 to 7.9)%.Conclusions:Changes in nonexercise ST and NEPA are variable among participants in an exercise-training program, with nearly half decreasing NEPA compared with baseline. Interventions targeting multiple behaviors (ST and NEPA) may effectively reduce compensation and increase daily activity.

Exercise training is an effective intervention for treating and preventing hypertension, but its effects on heart rate (HR) response to exercise and cardiorespiratory fitness (CRF) of non-hypertensive offspring of hypertensive parents (FH+) has not been studied. We compared the effects of three times per week equal-volume high-intensity aerobic interval (AIT) and continuous moderate-intensity exercise (CME) on HR response to exercise and CRF of FH+. Forty-four young FH+ women (25.0 ± 4.4 years) randomized to control (CON; n = 12), AIT (80–90% of VO2MAX; n = 16), or CME (50–60% of VO2MAX; n = 16) performed a graded exercise test (GXT) before and after 16 weeks of follow-up to evaluate HR response to exercise and several parameters of CRF. Resting, maximal, and reserve HR did not change after the follow-up in all groups. HR recovery (difference between HRMAX and HR at 1 minute of GXT recovery phase) improved only after AIT (11.8 ± 4.9 vs. 20.6 ± 5.8 bpm, p < 0.01). Both exercise programmes were effective for improving CRF parameters, but AIT was more effective than CME for improving oxygen consumption at the respiratory compensation point (VO2RCP; 22.1% vs. 8.8%, p = 0.008) and maximal effort (VO2MAX; 15.8% vs. 8.0%, p = 0.036), as well as tolerance time (TT) to reach anaerobic threshold (TTAT; 62.0 vs. 37.7, p = 0.048), TTRCP (49.3 vs. 32.9, p = 0.032), and TTMAX (38.9 vs. 29.2, p = 0.042). Exercise intensity was an important factor in improving HR recovery and CRF of FH+women. These findings may have important implications for designing exercise-training programmes for the prevention of an inherited hypertensive disorder.

The aim of the present study was to determine the effects of a 4-week exercise training intervention on blood glucose, insulin sensitivity, BMI (body mass index) and cardiorespiratory fitness in patients with Type 2 diabetes, and to identify and establish criteria for patients who are more likely to improve their blood glucose from short-term exercise training. A randomized, controlled trial of exercise training, comprising two supervised and one non-supervised sessions of individualized cardiorespiratory and resistance exercise per week, was performed in 132 healthy patients with Type 2 diabetes (exercise training group, n=68), with the aim of accumulating a minimum of 150 min of moderate-intensity exercise for 4 weeks. BMI, waist circumference, blood pressure, blood lipid profile, blood glucose, insulin, insulin sensitivity [calculated by HOMAIR (homoeostasis model assessment of insulin resistance) and QUICKI (quantitative insulin check index)], β-cell function (calculated by HOMAβ-Cell), HbA1c (glycated haemoglobin) and V̇O2max (maximal oxygen consumption) were measured at baseline and at 4 weeks. The exercise training group had significant improvements in V̇O2max, BMI and triacylglycerols (triglycerides). There were no significant changes in blood glucose, HOMAIR, QUICKI or HOMAβ-Cell. Decreases in blood glucose were significantly predicted by baseline blood glucose and HbA1c, with these variables accounting for 15.9% of the change in blood glucose (P<0.001). ROC (receiver operator characteristic) curve analysis revealed that patients with a blood glucose >8.85 mmol/l (sensitivity=73%, specificity=78%) and HbA1c >7.15% (sensitivity=79%, specificity=60%) were more likely to achieve a clinically significant decrease in blood glucose. In conclusion, in apparently healthy patients with Type 2 diabetes, a 4-week exercise intervention improved cardiorespiratory fitness, BMI and triacylglycerols. Elevated blood glucose and HbA1c predicted improvements in blood glucose.

In obesity, excessive abdominal fat, especially the accumulation of visceral adipose tissue (VAT), increases the risk of metabolic disorders, such as type 2 diabetes mellitus (T2DM), cardiovascular disease, and non-alcoholic fatty liver disease. Excessive abdominal fat is associated with adipose tissue dysfunction, leading to systemic low-grade inflammation, fat overflow, ectopic lipid deposition, and reduced insulin sensitivity. Physical activity is recommended for primary prevention and treatment of obesity, T2DM, and related disorders. Achieving a stable reduction in body weight with exercise training alone has not shown promising effects on a population level. Because fat has a high energy content, a large amount of exercise training is required to achieve weight loss. However, even when there is no weight loss, exercise training is an effective method of improving body composition (increased muscle mass and reduced fat) as well as increasing insulin sensitivity and cardiorespiratory fitness. Compared with traditional low-to-moderate-intensity continuous endurance training, high-intensity interval training (HIIT) and sprint interval training (SIT) are more time-efficient as exercise regimens and produce comparable results in reducing total fat mass, as well as improving cardiorespiratory fitness and insulin sensitivity. During high-intensity exercise, carbohydrates are the main source of energy, whereas, with low-intensity exercise, fat becomes the predominant energy source. These observations imply that HIIT and SIT can reduce fat mass during bouts of exercise despite being associated with lower levels of fat oxidation. In this review, we explore the effects of different types of exercise training on energy expenditure and substrate oxidation during physical activity, and discuss the potential effects of exercise training on adipose tissue function and body fat distribution.

Exercise is defined as any activity that causes your muscles to work and your body to burn calories. Physical activity includes swimming, running, jogging, strolling, and dancing, to name a few. Physically and mentally active people have been shown to have various health benefits. It could even help you live a longer life. In this article, we attempt to explain the beneficial effects of exercising regularly on our brain and how this helps with cognitive tasks. We also describe the various neurotrophic neurochemicals that aid in this phenomenon. We then describe the process of neuroplasticity and how exercise can help accelerate this process. Regular physical activity is one of the most important things you can do for your health. If you're worried about being harmed if you start walking or increase your level of physical activity, it is safe for most people to engage in moderate-intensity aerobic activity, such as brisk walking. Reduced emotions of state anxiety (short-term anxiety), increased sleep, and enhanced elements of cognitive performance are some of the benefits of moderate or intense physical exercise on cerebral health that happen immediately after moderate or intense physical activity (acute impact). People who engage in more moderate or intense physical activity generally have better mental processes to gain knowledge and comprehension than those who do not. Improvements in cognition, as well as performance, might be expected. For example, standardized assessments of academic achievement and performance on mental ability tests are examples of neuropsychological testing. Processing speed, memory, and executive function are all factors to consider.
