INVESTIGATION OF THE CARDIOVASCULAR FITNESS IN ATHLETES AND NONATHLETES Cardiova

Question

INVESTIGATION OF THE CARDIOVASCULAR FITNESS IN ATHLETES AND NONATHLETES Cardiovascular fitness can be determined by measuring a persons pulse rate before and after a given time of aerobic exercise, Fitness Index. Two groups of people (trained athletes and nonathlets) performed standard exercise. Each of them stepped up and down on a platform (8" from the ground) for 3 minutes at a rate 30 steps per minute. The persons pulse rate was measured before the test and immediately after test during 7 minutes with the one minute intervals. The data was recorded. by determining recovery time and calculating the Before Right1min. 2min 3 min 4 min | 5 min | 6 min | 7 min exercise After (0 Person min) |105 196 188 78 169 165 165 65 Athlete 1 65 Athlete 2 63 Athlete 3 | 68 | 103 Athlete 4 60 Athlete 5 6198 63 80 177 168 163 | 100 | 68 93 |87 |75 | 07 (60) 160 160 90 82716 61 61 61 | 85176-108) 168-68 101 Before Right exercise After (0 min min min min min min min Person 2 Min) 125 Nonathlete 1 72 Nonathlete 2 7 Nonathlete 3 78 Nonathlete 4 75 130 Nonathlete 5 77115 120 101 95 83 79 (72 72 121 110 100 92 85 80 119 99 90 86 8178 (78 121 106 98 91 88 79 75 128 100 97 93 8885 80 QUESTION: Who has better cardiovascular fitness, athletes or nonathlets?

Explanation / Answer

Answer :-

In the present time, the cardiovascular system of athletes and non athletes have been compared.

It is obvious that the weight of non athletes is more than that of athletes. That's why athletes are more fit than non athletes.

The regular exercise leads to the changes in the body. This has been observed that the cardiopulmonary, respiratory and locomatory function of athletes are way more better than the non athletes.

Conclusion : Sports play the vital role in cardiovascular system for a human body.
