In addition to squats and deadlifts I’ve been jumping off a ploy box to try to increase bone density in my lower body. Jumping off seems safer to me than jumping on. Would the forces generated be equivalent?

Does he feel that fasting plays a role in an athlete's life? So much emphasis is placed on building muscle but it seems that autophagy could play an important role for improving mitochondrial function and for overall health. Is there a balance between muscle hypertrophy and autophagy?

In what extent are recommendations about nutrition and supplements valid for all people - and which aspects are very personal and unique due to genetics, metabolism and culture?

Hi, Andy: I am a 71-year old male with a lifetime of endurance sports as a participant and as a physician advisor to other athletes. I started as a freestyle swimmer, and focused on the pool distance events of 400, 800 and 1,500 meters. After college swimming, I continued and reached a high performance benchmark of second in the world (per FINA rankings by my age group over a year) but found I had developed left ventricular hypertrophy (LVH) by both echocardiogram and ECG criteria. So, I changed my training to avoid HIIT stuff and “went long” with abandonment of the pool distances and switching to open water 5 and 10k events and doing long hikes and bicycling here in Colorado. My LVH resolved. This last weekend I was able to hike three “14-er” peaks over three days with 10,000 feet of total climbing and an average HR of 110. Enough background; my question to you is regarding what advice you would give the 70+ athlete from your experienced and researched perspective regarding aerobic conditioning and longevity? Thank you for your consideration!
