Common Questions and Answers about Exercise physiology human kinetics


3151606 tn?1420356612 During an EP study, to test atrioventricular conduction, they artificially stimulate the atria at increasing speed until the AV node (the "gatekeeper") is starting to block impulses. This is known as the "Wenckebach point". One may think this is similar to max pulse (maximum HR during exercise) but that's not correct. When you exercise you release lots of adrenaline which both stimulate the sinus node and the AV node to allow more rapid conduction.
Avatar f tn , you will find nice tutorials addressing your question. However, it will be necessary for you to have studied human anatomy and physiology even to begin to get a grip on it. The reason is that this is highly technical stuff that is almost impossible to explain to people without some specialized education. At the bottom of your ekg report, there should be some kind of brief summary describing your heart's health in fairly plain English.
Avatar f tn If you wake out of sleep at night, 'adrenal surges'--even though the adrenals are the fashionable gland of the hour and you can read about them in supermarket checkout lines everywhere--are the least likely cause. The most likely causes are sleep phase disruption due to depression or anxiety (extremely common), or nocturnal panic attacks. You can google these terms.
Avatar f tn Overall, since you are clearly healthy, unless you have taken real classes in anatomy and physiology, you will be better off *not* getting hung up on minor findings in your EKG. And again, overall, getting therapy for your health anxiety will free you up to enjoy your life.
Avatar m tn Thanks NTB. Interesting article and it does alleviate my concerns about the potential for LVH due to the inotropic effect of Sotalol and beta blockers in general. That's good to know. That said, the study doesn't exactly address my situation as it was done on people who were actually in a-fib during the tests (two of them actually cardioverted during the study - lucky them).
Avatar m tn was that the invitro study or a human study?unfortunately no human study started that i know of although they were on schedule since 2008-2009 so this makes me suspicious......
Avatar m tn Other thing I emphasised that human PHYSIOLOGY is mostly ignored in modern medical science! I picked up pregnancy because it's importance is paramount for mankind development, and recently I experienced how doctors treat that in evaluation of pregnancy. In my opinion, medical science should have done better than they are doing today.
Avatar m tn Anyone have thoughts on promoting natural secretion of human growth hormone (hGH)?
Avatar m tn Consuming sugar within this post-exercise window, will negatively affect both your insulin sensitivity and your human growth hormone (HGH) production. A recent study in the Journal of Applied Physiology found that eating a low-carbohydrate meal after aerobic exercise enhances your insulin sensitivity.
Avatar n tn Note that single bouts of exercise have profound BENEFICIAL effects on physiology and metabolism and especially the vascular system so it may not be too far fetched. I am often angered by people and doc's who are quick to dismiss exercise as dangerous for many retina conditions because of the pressure increase but there is almost NO evidence to support this (except maybe valsava retinopathy).
Avatar f tn First of all, never give an animal any medication that is not prescribed by your vet. Some human medicines can make animals very sick or even kill them. Go to the vet, please.
Avatar f tn Threshold is point at which you generate an action potential...below it there is no response and anything above it produces a response. The response is "all-or-none", that is an action potential is what is generated. If I remember my physiology and understand your question... a delay in reaching threshold will increase the time in-between the action potentials generated thereby reducing their frequency. Hope this make sense.
Avatar f tn I have been seeing a cardiologist because I can't exercise long before my heart rate jumps to over 170. I'm a 52 year old woman in otherwise good health. I recall having this problem all my life. I'm tried continued exercise to build up my tolerance but I never get any improvement. My respirologist did a stress test which showed I change from an aerobic to an anaerobic state at an early stage of exercise. Do you know what this might be. The cardiologist seems stumped also.

Avatar m tn is NOT a complication of cataract surgery. It occurs due to the continuance of normal human lens physiology. The risk associated with yag capsulotomy are small but will vary from person to person depending on pre-operative degree of myopia, whether there is a family history of retinal detachment or retinal pathology such as lattice degeneration. You should discuss this with your surgeon.
Avatar f tn Is it possible that 2 leaky valves would cause my heart rate to elevate quickly during exercise? If so how am I supposed to exercise? Any help would be greatly appreciated.
Avatar f tn my husband can eat shrimp, but if I did I would be nauseated and vomiting after eating them. PLAIN AND SIMPLE: I JUST DON"T EAT THEM.
Avatar n tn While it looks good on paper, based on actual physiology of exercise and pathology of diabetes whether type 1 or 2 is not that easy to do and could be dangerous due to occurrence of hypoglycemia during or after exercise. I am not a doctor but reading the physiology of exercise which got very interested when my doctor announced that I am now a bona fide type 2 diabetic, i question the effectiveness of more intensive or vigorous exercises.
Avatar m tn A question on behalf of my uncle. Lack of exercise is a risk factor for coronary heart disease. Is it because no exercise can increase cholesterol or is there some other reason.???
Avatar n tn To provide a perspective, it is true everyone has different physiology, respond differently to therapy, etc, but in a general sense aerobic exercise is beneficial and recommended on a continuing basis....that would include at a brisk walk at least 3 time a week for a half hour. There should be some resistant training to maintain muscle tone and strength.
Avatar m tn 3 cm in diameter, with slow progressive benign type enhancement kinetics (type 1 curve). I have another MRI next month (which is 8 months later- they forgot to schedule it at 6 months). My doctor states that I am higher risk then normal and I have also found another lump since then. I had a rough few months with all of the testing I did before and I am assuming the area of concern is the 4:00 position...
