Where's Your Physical Limit?

Where's Your Physical Limit? You may remember a few months back when ON's Breaking News reported on one amazing athlete's completion of 50 Marathons in 50 Days. Migrating birds can sustain an energy level approximately 5 rimes their metabolic rate. So how far are humans able to push their physical abilities? A study published in the journal Medicine & Science in Sports & Exercise analyzed 5 to 10 days of intense physical activity and found that such levels can be sustained by elite athletes without severe catabolism, as long as their energy intake keeps pace with energy demands.

True Strength Moment: No one is able to maintain high levels of exercise intensity 50 or 100 days, but going hard for as long as 10 days can make a huge difference in an ultimate marathon event. The danger is extreme weight loss from the enormous amounts of calories that are burned up during such an effort. For those who are determined to push on, there is no pre-determined limit to performance
