The figure below (click to enlarge) is from the outstanding book Physiology of sport and exercise , by Jack H. Wilmore, David L. Costill, and W. Larry Kenney. If you are serious about endurance or resistance exercise, or want to have a deeper understanding of exercise physiology beyond what one can get in popular exercise books, this book should be in your personal and/or institutional library. It is one of the most comprehensive textbooks on exercise physiology around. The full reference to the book is at the end of this post. The hormonal and free fatty acid responses shown on the two graphs are to relatively intense exercise combining aerobic and anaerobic components. Something like competitive cross-country running in an area with hills would lead to that type of response. As you can see, cortisol spikes at the beginning, combining forces with adrenaline and noradrenaline (a.k.a. epinephrine and norepinephrine) to quickly increase circulating free fatty acid levels. Then free fatty...

62-yr-old Woman with Hypertention, Ventricular Hypertrophy and Congestive Heart Failure

One of the considerations with congestive heart failure is the need for fluid restriction and the patient will need to work her doctor to be able understand how much she should be getting daily. Sodium restriction is important for bringing down the blood pressure. In the case of this woman, I would employ a DASH diet to bring down her blood pressure with emphasis on plenty of fruits and vegetables as well as dairy products such as yogurt to obtain regular amounts of calcium. Since being overweight contributes to higher blood pressure, if she is overweight, then the DASH diet should be combined with a weight loss program by restriction of calories. Regular aerobic exercise can also support healthy blood pressure levels. I'd recommend about 30 minutes three times weekly. Because of her condition, I'd also recommend supplementation with CoQ10 to support the function of the heart. If she has a low vitamin D status, which is associated with higher blood pressure, then I'd also r...
