Body Talk: Little-Known Facts

          By Caral Goh
 

The amazing heart muscle

 
            You probably experience tired muscles in your legs after running some distance or fatigued hand muscles after playing basketball. Those parts of the body need to be rested after exertion. However, the heart muscle is one that we never have to rest until our final breath.The heartbeat at rest is an average of 80 beats per minute. That adds up to 4,800 beats in an hour. It is a whopping 115,200 times per day,and an astonishing 42,048,000 times per year.At 80 years old, your heart would have beaten over three billion times: 3,363,840,000 heartbeats. What an amazing muscle.
 

Why we don’t get heart tumors

 
            Tumors grow when abnormal cells divide uncontrollably. Unlike the cells of other organs, the ones in the heart do not split and multiply, except during fetal development. That’s good news for our heart, our most precious organ. However, when a heart attack occurs, the tissue of the heart cannot be regenerated.
 

Complex network of the feet

 

           In the feet, there are 26 bones, 33 joints, 112 ligaments, and a network of nerves, tendons, and blood vessels that work together when we run. Professional runners have extremely consistent strides, usually between 185 and 200 strides per minute.

 

 

Standing is not resting

 
           When you stand, your legs are not resting.Each foot and leg supports about half your body’s weight without a break and the same few muscles, mostly in your calves, have to work constantly to keep you balanced and upright. After a prolonged period of time, the muscles are tired out. In addition, the heart is not able to pump blood efficiently when you stand still, which can lead to blood pooling. Walking is actually easier on your body as the burden is distributed amongst a greater number of muscle groups, and your weight shifts back and forth, giving each leg and foot a brief break.
 

Running for a year

 
           We can sweat better than any other mammal on Earth, making us the best runners for long distances.The new world record for long-distance running was set by French ultramarathon runner Serge Girard. Running every day for 365 days,he traversed 25 countries and covered a total of 27,011 kilometers.
