The role of physical activity in cardiovascular health has received increasing atten­ tion in recent years. A large number of reports have indicated that populations or individuals with high levels of physical activity tend to have a lower prevalence of symptomatic coronary artery disease and lesser death rates from cardiovascular diseases (69, 139). Although no single report provides complete proof that physical activity has a protective effect, the evidence heavily favors that conclusion. The… 

Exercise and physical activity in the adult population

The percept ion exists that there are many more vigorous exercisers now than there were 5 20 years ago, but what may be happening is a progression of exercise from individuals' doing some form of moderate exercise to the same individuals' do ing more strenuous exercise.

Physical Activity for Healthy Adults: Counseling as a Primary Preventive Intervention in Clinical Settings

Evidence suggests that although there has been an increase in leisure-time physical activity by American adults during the 1970s and 1980s, the rate of increase has recently declined, and the role of physical activity in preventing CHD in particular is of major public health importance.

Aging, fitness and muscular performance

It is recognized that in elderly people the balance shifts; muscle performance, changes in blood distribution and peripheral microvascular capacity become ever more important determinants of exercise performance and should command increasing research interest.

Effects of aerobic training on heart rate

A reduction of the cardiac vagal tone and consequently a diminished HR variability inrest, independently of the protocol of measurement used, is related to an autonomic dysfunction, chronic-degenera-tive diseases and increased mortality risk.

Aerobic Exercise and Strength Training Effects on Cardiovascular Sympathetic Function in Healthy Adults: A Randomized Controlled Trial

It is shown that moderate aerobic exercise training has no effect on resting state cardiovascular indices of PEP and LF BPV, indicating that in healthy, young adults, the cardioprotective effects of exercise training are unlikely to be mediated by changes in resting sympathetic activity.

Long‐Term Physical Training and Cardiovascular Dynamics in Middle‐Aged Men

It is concluded that aside from subjective enhancement of well-being, a well-planned physical training program for middle-aged men can develop beneficial economy and efficiency of myocardial function and the oxygen transport system.

Effects of a Quantitated Physical Training Program on Middle‐Aged Sedentary Men

The effects of a 15-week quantitated training program were evaluated in nine men, 32 to 59 years old, who had been blind for 10 years or more but were otherwise in good health and who discontinued training after 15 weeks.

Physical training in sedentary middle-aged and older men. I. Medical evaluation.

In a group of 68 middle-aged sedentary men participating for 2 months in hard physical training, 5 were initially advised against participation for medical reasons; 54 subjects completed the training program and a significant reduction of the iron and cholesterol levels in the serum occurred.

Chronic training with static and dynamic exercise: cardiovascular adaptation, and response to exercise.

It is suggested that endurance training alters both the absolute and relative left ventricular mass and the response of the cardiovascular system to static exercise, as static exercise training increases the absolute but not the relative left Ventricular mass.

Effect of a mild exercise program on myocardial function and the development of hypertrophy.

The data suggest that the heart from an exercised animal is better able to tolerate increases in afterload and hypoxia and can respond with compensatory myocardial hypertrophy more rapidly than the heart of a sedentary animal.

Influences of Physical Training on the Heart of Dogs

To investigate the effects of physical training on cardiac dimensions and function, eight dogs were exercised for 12 weeks by treadmill running 1 hour/ day, 5 days/week. Five dogs were confined in

Coronary circulation during heavy exercise in control subjects and patients with coronary heart disease.

The impaired myocardial performance was best demonstrated in two patients with exercise-provoked angina pectoris who developed rapidly increasing left atrial pressure.

Physiological Analysis of Middle‐Aged and Old Former Athletes: Comparison with Still Active Athletes of the Same Ages

Blood lipids, red cell volume, heart volume, dynamic spirometry, electrocardiograms made at rest and during exercise, and maximal oxygen uptake were determined in 29 former athletes 45 to 70 years
