Question
NONATHLETES GATION OF THE CARDIOVASCULAR FITNESS IN ATHLETES AND Cardiovascular fitness can be determined by measuring a persons pulse rate before and wo groups of people (trained athletes and nonathlets) performed standard e was measured before the test er a giv Fitness Index. T en time of acrobic exercise, by determining recovery time and calculating the 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 rat and immediately after test during 7 minutes with the one minute intervals. The data was recorded Person Before Right 1 min 2 min 3 min 4 min 5 min 6 min 7 min exercise After (0 Athlete1t65105-96-88-78-69- 65 65 65 80 7768 6363 63 63 68 100 85 76 68 68 68 Athlete 3 68 Athlete 5 61 Person 103 101- 19387-75-67- 6060-60 198 190182-71161-161-161-161 Athlete 4 60 Before Right 4 5 exercise After (0 min min min min min min min 120 101 95 83 79 72 72 Min 125 124 Nonathlete 1 72 Nonathlete 2 77 Nonathlete 3 78 Nonathlete 4 75 130 Nonathlete 5 77115 121 110 100 92 85 80 77 119 99 90 86 81 78 78 121 106 98 91 88 79 75 100 97 93 88 85 80 77 QUESTION: Who has better cardiovascular fitness, athletes or nonathlets? HYPOTHESIS PREDICTION INDEPENDENT VARIABLES: DEPENDENT VARIABLES CONTROLLED VARIABLES: CONTROL Summarized Tables for pulse rate and recovery time Graph for pulse rate Graph for recovery time SummaryExplanation / Answer
Athletes are better because they do not get too high heart rate after exercise. More heart rate is sign of higher exertion.
Hypothesis: Performing exercises can make cardiovascular muscles stronger to evade exertion.
Prediction: Athletes will have low heart rate increase and higher recovery than nonathlete.
Independent variables: Time
Dependent variable: heart rate
Controlled variable- standard exercise
Control- Nonathlete
