The USA Pro Cycling Challenge provided a timely backdrop Thursday for a related event that highlighted the roles of heart and lungs.
Demonstrations and participatory tests held in Rotary Park covered functions of the lungs and heart, nutrition, flexibility, the difference between slow- and fast-twitch muscles and the effects of cigarette smoke.
One popular test of lung power recorded the maximum number of watts a participant could produce by pedaling a bicycle.
Visitors also could see a heart and body models, be evaluated for physical therapy, learn about the value of bicycle helmets and see ones own heart work through a noninvasive echocardiogram.
The overall title of the program was Physiology in the Park, presented by Performance Cardiology of Dr. Bruce Andrea and the Durango Sports Club.
Among highlights of the 2½-hour event:
Todd Wells, a three-time Olympic mountain bike racer, was interviewed. Wells finished 10th in his event in London, the highest finish ever for an American man.
Kathryn Ross, 22, a triathlete, is leaving the professional ranks to enroll at Fort Lewis College, where shell be on the cycling team. Ross was subjected to a stress test that measures lung capacity.
Dr. Ed Razma, a pulmonologist at Four Corners Sleep Disorders Center at Mercy Regional Medical Center, demonstrated how cigarette smoke affects the lungs.
