What cardiovascular adaptations are associated with physical fitness?

Sorry I can't answer your question but can I suggest that you try posting this question in the Health and Beauty category, you'll probably get better answers.

For cardiovascular exercises you can walk, run, swim, bike, hike, do yoga and/or pilates, any aerobics class, elliptical, stairmaster, canoeing\n\nHope this helps.\nwww.jifitness.com

Blood pressure = Cardiac output * total peripheral resistance.\n\ncardiac output is the amount of blood pumped out by the left ventrical per minute~5L/min\n\nCardiac output= heart rate * stroke volume\n\nheart rate is number of times the heart beats per minute and stroke volume is End systolic volume - end diastolic volume. \n\nWhen your start to run, there will be a mass sympathetic discharge from your brain. So your hearts pumps harder and faster. Heart rate increases and heart contractility increases. so cardiac output increases from 5 L to say 8L or more. However BP does not increase as much because total peripheral resistance acturally decreases instead of incrases. As you run, the mucles that are oxygen starved release vasodilators into the blood vessels. These cause the smooth muscle around the arterioles to vasodilate. Therefore resistance to blood flow actually decreases. Hope this explains what you've been looking for.

All parts.\nCardio-vascular system, because it gets your heart rate up.\nStretches muscles in the legs, back, arms, torso, and neck.\n\nIt does not actually "target" any one group or area, if that helps.  It is a general warm-up exercise.

Definitely some moderate Cardio Exercise...Like riding a bike, a brisk walk...jogging, swimming. Just getting active and drinking plenty of h20 helps me!

So that his body gets adapted... as he does more exercise, his heart will pump more forcefully, so it will undergo a compensatory increase in size... and this will make him able to pump more blood to those muscles!

Maybe not promotes but gives you a good guideline. An elevated heart rate in exercise is necessary to burn calories and fat but it can also warn you if have over exerted yourself and helps you set a pace that meets your needs. Depending on what kind of shape you are in affects your exercising heart the more out of shape the higher the heart rate.

cardio is things that bring your heart rate up... exercising your heart and helping your blood flow. cardio can be with equipment or without. sitting in your chair and lifting your legs, and even endurance trainings are part of cardio since they bring your heartrate up fast.\n\naerobic exercises are when you workout without weights or equipment. thus the aero prefix. in older definitions aero prefix was to train your breathing. but modern definitions are non-stress exercises... different college texts show both definitions depending on the training involved.

As the heart increase in size, the surface area increase by the square, while the internal volume increases by the cube.\nExample: internal volume = Length * Width * height\n\nAs the internal volume increases the amount of blood pumped per heart beat (stroke volume) increases.\n\nThe actual “strength” of the heart is unchanged. Cardiac myosites are essentially unchanged between different mammal species. \n\nWell trained athletes tend to have a health heart hypertrophy (enlarged heart) and have heart beats in the 40’s-50’s BPM while the average adults range in the 60’s-80’s.\n\nAs an end product of all of this, large animals tend to have slower metabolic rates because while it may be possible for a 6 oz bird to eat its weight in insects a day a large animal like a dog can not be expected to do so.

Flexibility, cardiovascular endurance, muscular strength, muscular endurance and body composition. Flexibility-reaching and moving about daily, cardiovascular-depends on your job, but walking three times a day for short walks of 10 min. will work. Muscular strength-lifting heavy objects during the day. Muscular endurance-repetitive lifting of objects. Body composition-smart choices in healthy eating.

Isometric exercises.\n\nFitness Zone offered a slightly different definition. According to the article, isometric exercises are those in which a force is applied to a resistant object. An example is pushing against a brick wall -- even though there is a build up of tension in the muscles, there is no actual movement. The web page emphasizes a few points for people thinking about isometric exercises: \n\nTo increase strength, it's necessary to maintain a position in any one exercise for 6 to 8 seconds. \n\nThe exercise should be repeated 5 to 10 times. \n\nAny one isometric exercise will only increase muscle strength at one joint angle. Strengthening the other joint positions requires repetition of further corresponding exercises. \n\nIsometric exercises on their own are not recommended for strength training. They are only part of a complete exercise program. \n\nIf you suffer from heart disease or raised blood pressure, you should steer clear of isometric training. During the muscular contractions in this form of exercise, blood pressure can rise quite dramatically. \n\nhttp://ask.yahoo.com/20001005.html

The reason we don't have muscles like our heart is because we don't work our other muscles as hard as are heart.\nIf you work the reps that our heart beats for each group of muscles. We all could lift 10 or better times our weight.\nA good program of strengthening exercises for your muscle groups. Along with running and cardiovascular\nexercises. Will help you be stronger and healthier to live a better life.

Boxing will give you a more complete workout, but running will give you a higher cardio workout.

Treadmill stress electrocardiography is employed widely to detect underlying cardiovascular disease in asymptomatic persons. To determine the frequency and significance of an abnormal S-T segment response to exercise in young athletes with increased left ventricular (LV) mass induced by physical conditioning, 75 male isometrically trained athletes without evidence of heart disease (mean age 21 years) and 48 nonathletic young normal subjects were studied by M-mode echocardiography and exercise electrocardiography. Ventricular septal and posterior free wall thicknesses and calculated LV mass were significantly greater in athletes than in control subjects. An abnormal S-T segment response to exercise was present in 7 (9%) of the 75 athletes, all of whom had a LV mass greater than 275 g and in 5 the LV mass was above the 95th percentile of that of the control subjects. An abnormal treadmill exercise test result also was present in 3 (6%) of 48 control subjects. Seven of the 10 subjects with abnormal exercise test results had radionuclide angiograms at rest and with exercise, each of which was normal. It is concluded, therefore, that (1) abnormal exercise test results occur commonly in both athletes and non-athletes; (2) almost 10% of isometrically trained athletes have "false-positive" exercise electrocardiograms, suggesting that this test has major limitations in screening for underlying cardiovascular disease in athletes; and (3) in athletes, a relation was present between "physiologically" increased LV mass and false-positive exercise test results.
