Cardio while on cycle

[Bobber]

What are the boudaries as far as burning fat but not enlarging the heart? What should my target BPM be?

 

[BOWTECH]

I just had an EKG and some other test done on my heart and everything is good. And I do cardio 5-6 days a week. Balls out. I don't believe in the computers on the machine so I don't care about the readings. But I have been lifting and doing cardio for many years and never have heard of someone getting an enlarged heart from cardio.

But if it does enlarge your heart I must have a pumpkin in my chest by now.

great question to which i still cannot find a solid answer--there is evidence of some enlargement while on gear if you do excessive (whatever that is) and other that cannot tell if its genetic or gear induced--and still others that say there is no growth.

so if one of the real brainiacs on the site could answer this i too would appreciate (as would my maybe enlarging heart)


here is an letter to the editor of the Journal of American College of Cardiologists demonstrating the disagreement of an earlier study--if these geeks cant agree........

We read with great interest the study by Abernethy et al. entitled "Echocardiographic Characteristics of Professional Football Players" (1). The investigators report on a high relative wall thickness of 0.424, reflecting an emphasis on strength training.
Although the investigators state that "steroid use among the participants was not known," no data are presented to underline this important statement, nor is the possibility of an anabolic steroid-induced hypertrophy discussed. It is well known that anabolic steroid use is not uncommon among professional football players as the National Football League does not perform doping tests as required by the World Anti-Doping Agency (WADA) among professional athletes of most other sports. To prove the investigators' statement of having examined steroid-free football players, a screening test for doping substances could have been performed, or at the least parameters of clinical chemistry which are altered by the use of anabolic steroids (e.g., follicle-stimulating hormone, luteinizing hormone, sex-hormone binding globulin, cholesterol, low-density lipoprotein, high-density lipoprotein, alanine aminotransferase) should have been given in the paper. The researchers also do not present data on diastolic function, which may be restricted in anabolic steroid users and thereby contribute to a differentiation between a physiological and pathological myocardial hypertrophy (2–5). Furthermore, a description of the athletes’ training history (years of training, hours per week spent for strength training) would have been helpful.

As reported previously, the relative wall ratio in anabolic-free soccer players, rowers, weightlifters, and bodybuilders usually is about 0.40 and differs significantly from higher values in anabolic steroid-using bodybuilders (5). This influence of anabolic steroids on the left ventricular wall has also been demonstrated by others (2–4,6). Additionally, the cited study of Pelliccia et al. (7) found a left ventricular wall thickness of 13 mm in only 1.7% (15 rowers or canoists and 1 cyclist—each of them having a left ventricular end-diastolic diameter >54 mm) in 947 athletes, whereas Abernethy et al. (1) present about 28% of the football players having a left ventricular wall thickness of 13 mm in their Figure 2, but they only mention 11% (17 of 156) with more than 13 mm in the Results section, which are cited as 6% in the Discussion section of their study (1).

Furthermore, Abernethy et al. (1) do not cite their used echocardiographic convention and probably determined myocardial wall thickness by the Penn-Convention (8) (otherwise the use of the Penn-Cube formula [8] for left ventricular mass determination is not admissible). Because the Penn-Convention (8) excludes the epi- and endocard from septal and posterior myocardial wall thickness, an underestimation compared to the data of Pelliccia et al. (7), who determined the myocardial wall thickness by use of the convention of the American Society of Echocardiography (9), has to be presumed.

Therefore, we do not share the opinion that the data presented allow for the conclusion that a strength-training-induced high relative wall thickness in professional football players reflects a physiologically induced (concentric) hypertophy.

Cardio won't cause ane enlared heart unless you have heart disease: High BP, plaque build up in coronary arteries, heart valve issues. This makes the Heart work harder. And because it's a muscle it gets bigger just like your other muscles when forced to do more work. If your cardiovascular system is in check your heart will just get stronger.

 

[hurricane]

its crazy how many wrestlers have died from enlarged hearts.. was reading on this, the other day

 

[Nelson Montana]

All that targeted heart rate stuff is bullshit. My cardio is 20 rep squats. I also walk a lot and ride a bike -- one that actually gets me from point A to point B.

Yup the high rep squats have my heart pounding pretty good. Also on a side note the "One & a Half" technique described in your book is amazing. (cruel but amazing)

well cardio does enlarge your heart, but in a balanced way so that it lowers all your cardiac risk factors

the problem with steroids is the type of enlargement they produce is very specific in that it is primarily left ventricular hypertrophy while the other chambers of the heart lag behind, cardio helps to offset this which is why endurance exercise is so good for your heart.

enlartgement of the heart is actually a good thing if its all four chambers being strengthened, but when its just the left ventricle it is cause for concern (i.e. with powerlifting and gear usage)

that makes sense but what about intense & sustained cardio while on?

 

[Faizakafez]

you need cardio on or off...

to keep bf levels low and for cardiovascular health.

 

[off_safety]

what are you trying to get out of this cycle, mass or cuts? atleast walking on the treadmill post workout with the incline set on high should give you a decent amount of cardio and get the lactic acid out of your muscles.

 

[bigjd69]

I was under the impression that anyone that exercises, lifts weights or participates in any other athletics on a regular basis has a larger left ventrical than say the lay person.

lmao

Tons of wrestlers die of heart failure because the only only cardio they get is 20 rep squats other than performances. This is not adequate cardio, it has to be sustained so your body adapts, just like strength training.

Remember, the most important blood vessels in your body are the ones bringing oxygen to your heart muscle. People whose left ventricles grow faster than these vessels or who don't maintain these vessels through regular cardio have part of the left ventricle die, called a "heart attack"

the left ventricle can grow with any added work, being lifting weights or adding plaque to you vessels ,

The stuff about lactic acid is bullshit, look it up, cardio after heavy lifting will hurt your gains. cardio should be done seperate.

If you find it harder to to do cardio than lift weights , you should do more cardio, and vice versa.

Swarzennegger had a heart attack, too , don't forget, in 40's, not healthy

One idiotic remark after the other.

Are you saying 20 rep squats won't increase heart rate? It doesn't require oxygen? And that's why wrestlers die? The tons of drugs and excessive weight and beatings that they take have nothing to do it it? It's no cardio. Got it. And by the way, try wrestling for hours and tell me it isn't cardio.

The most important blood vessels carry oxygen? They ALL carry oxygen.

Heart attacks are not caused by lack of running on a threadmill.

Swartzenegger had a congetital condition.

One stupid ass comment after the next. Do us all a favor. If you want to come off like a know-it-all, at least have a clue. And do it someplace where the people have a mental handicap. You sound like an ass.

ALL IDIOT ANSWERS


Heart disease - enlarged heart


The heart is a muscular pump about the size of a clenched fist. An enlarged heart isn’t a condition in itself, but a symptom of an underlying problem that is causing the heart to work harder than normal. The range of underlying problems falls generally into two main categories - pathological (linked to actual disease of the heart muscle disease) and physiological (linked to other causes which are overworking the heart muscle, such as high blood pressure or thyroid diseases). Older people are at increased risk. Another name for an enlarged heart is cardiomegaly.
Symptoms
In some cases, an enlarged heart is asymptomatic (has no symptoms). When symptoms do occur, it may be because the heart fails to pump blood effectively and this leads to a syndrome known as congestive heart failure. Symptoms may include:

Breathing problems
Shortness of breath
Dizziness
Irregular heartbeat (arrhythmia)
Heart palpitations
Fluid retention.
A range of causes
Some of the many causes of enlarged heart include:
Coronary artery disease - fatty deposits or plaques build up inside one or more of the coronary arteries (atherosclerosis). This constant silting narrows the artery. This reduces the oxygen supply, which is the fuel for the pump.
Cardiac ischaemia - reduced blood flow to the heart. This condition can cause heart pain (angina).
High blood pressure (hypertension) - blood pumps with more force than usual through the arteries, which puts strain on the heart. Causes of high blood pressure include obesity and a sedentary lifestyle.
Idiopathic dilated cardiomyopathy - disease of the heart muscle, the cause of which is unknown. Enlarged or ‘dilated’ heart is one of the most common types of cardiomyopathy. Some of the symptoms include chest pain and fainting spells.
Myocarditis - an infection of the heart that is generally caused by a virus. A person may have a viral illness first and later have symptoms of congestive heart failure.
Heart valve disease - for example, a faulty mitral valve allows blood to flow backwards, which means the affected heart chamber has to contract with more force than usual.
Previous heart attack - a weakened heart muscle may enlarge in order to keep up with the demands of pumping blood around the body.
Thyroid disease - the thyroid gland regulates many metabolic functions. Untreated, a thyroid condition can lead to high blood pressure, high blood cholesterol levels, irregular heartbeat and enlargement of the heart.
Obesity - carrying too much body fat is a risk factor for high blood pressure, which in turn can cause the heart to enlarge.
Lack of exercise - leading a sedentary lifestyle is a known risk factor for a range of conditions, including coronary heart disease and high blood pressure.
Old age - as we get older, our arteries lose some of their elasticity. This ‘stiffening’ of the blood vessels causes high blood pressure, which is a risk factor for enlarged heart.
Diagnosis methods
An enlarged heart is diagnosed using a number of tests including:
Medical history - including a physical examination.
Chest x-ray - this allows the doctor to see the overall shape and size of the heart and lungs.
Echocardiogram - sound waves sent to a special machine present a picture of the beating heart, so the doctor can see the heart as its chambers contract and relax.
Doppler ultrasound - shows bloodflow through the heart valves. This test is often performed in conjunction with the echocardiogram.
Electrocardiogram - measures electrical activity in the heart and can help diagnose an enlarged heart.
Treatment options
Treatment depends on the underlying cause but can include:
Medications to stop the heart from enlarging any further.
Treatment to address the underlying problem, such as diet, exercise and medication to help control high blood pressure, or surgery to replace a faulty heart valve.
Regular cardiovascular exercise.
Low fat diet.
Dietary adjustments to reduce blood cholesterol levels.
Frequent medical check-ups to make sure the treatments are working.
Where to get help
Your doctor
Cardiologist.
Things to remember
An enlarged heart isn’t a condition in itself, but a symptom of an underlying problem that is causing the heart to work harder than normal.
Some of the many causes include coronary heart disease, idiopathic dilated cardiomyopathy, high blood pressure and heart valve disease.
Treatment depends on the cause, but can include diet and lifestyle adjustments, medication and surgery .

Which answer is the most Idiotic?

 

[bigjd69]

According to WikipediaWhile ventricular hypertrophy can occur naturally as a reaction to aerobic exercise and strength training, it is most frequently referred to as a pathological reaction to cardiovascular disease, or high blood pressure.[1] It can occur naturally!!!!

 

[eddymerckx]

but the main issue is left venticular hypertophy--even the docs can't agree--

 

[halfcenturian]

Which answer is the most Idiotic?

Yours.

 

[eddymerckx]

Yours.

woooo hoooo it's not mine

 

[halfcenturian]

J/K, No stupid answers. Just mis-informed. Not trying to be a dick.
I did find this article, regarding US GUYS, and enlarged heart.
Does not appear to be a problem IN MOST CASES.

Peace. Out.


Additionally, a small number of patients have an enlarged heart with no known cause (idiopathic).

Another condition, sometimes referred to as “athlete’s heart,” can occur in high-level athletes who engage in regular, sustained and often intense exercise. In most cases, this is not a medically significant or dangerous condition for them. Some studies, however, have shown that even among elite athletes, an enlarged heart may raise the risk for heart failure. Athletes at all levels are recommended to undergo regular physical exams to rule out hidden or underlying heart defects.

 

[Rexxx Even]

WOW..You guys are sooo DEEP.

 

[bigjd69]

As I asked which answer is the most idiotic????

 

[Bobber]

Ok...I know that the heart maybe enlarged due to your genes or due to training hard for extended periods of times. I respect and accept all your answers but what I want to know is what should I do to burn fat and not enlarge my heart as a side effect. I don't wanna die early. That is all.

 

[bigjd69]

years 100–170 beats per minute 200 beats per minute
25 years 98–166 beats per minute 195 beats per minute
30 years 95–162 beats per minute 190 beats per minute
35 years 93–157 beats per minute 185 beats per minute
40 years 90–153 beats per minute 180 beats per minute
45 years 88–149 beats per minute 175 beats per minute
50 years 85–145 beats per minute 170 beats per minute
55 years 83–140 beats per minute 165 beats per minute
60 years 80–136 beats per minute 160 beats per minute
65 years 78–132 beats per minute 155 beats per minute
70 years 75–128 beats per minute 150 beats per minute

Your maximum heart rate is about 220 minus your age. The figures above are averages, so use them as general guidelines.

Note: A few high blood pressure medications lower the maximum heart rate and thus the target zone rate. If you're taking such medicine, call your physician to find out if you need to use a lower target heart rate. Hope this helps your original question of what your target heart rate should be.

Doing cardio on cylce shouldn't hurt you.
