# Measurements on men involved in a physical fitness course at N. C. State University. # Fitness is typically measured by oxygen intake rate (oxy) which is difficult (at # least cumbersome when one is exercising oneself) to measure. The study goal is to # develop an equation to predict oxy based on exercise tests rather than on oxygen # consumption measurements. # # The dataset has 31 observations. The variables in the data set are: # oxy (oxygen intake rate, ml per kg body weight per minute) # age (in years) # weight (in kg) # runtime (time to run 1.5 miles, in minutes) # rstpulse (heart rate while resting) # runpulse (heart rate while running, at the same time when oxygen rate was measured) # maxpulse (maximum heart rate recorded while running). oxy age weight runtime rstpulse runpulse maxpulse 44.609 44 89.47 11.37 62 178 182 59.571 42 68.15 8.17 40 166 172 45.681 40 75.98 11.95 70 176 180 60.055 38 81.87 8.63 48 170 186 44.754 45 66.45 11.12 51 176 176 49.156 49 81.42 8.95 44 180 185 46.774 48 91.63 10.25 48 162 164 46.08 54 79.38 11.17 62 156 165 45.118 51 67.25 11.08 48 172 172 50.545 57 59.08 9.93 49 148 155 47.467 52 82.78 10.5 53 170 172 45.313 40 75.07 10.07 62 185 185 49.874 38 89.02 9.22 55 178 180 49.091 43 81.19 10.85 64 162 170 50.541 44 73.03 10.13 45 168 168 47.273 47 79.15 10.6 47 162 164 40.836 51 69.63 10.95 57 168 172 50.388 49 73.37 10.08 67 168 168 45.441 52 76.32 9.63 48 164 166 39.203 54 91.63 12.88 44 168 172 48.673 49 76.32 9.4 56 186 188 54.297 44 85.84 8.65 45 156 168 44.811 47 77.45 11.63 58 176 176 39.442 44 81.42 13.08 63 174 176 37.388 45 87.66 14.03 56 186 192 51.855 54 83.12 10.33 50 166 170 46.672 51 77.91 10 48 162 168 39.407 57 73.37 12.63 58 174 176 54.625 50 70.87 8.92 48 146 155 45.79 51 73.71 10.47 59 186 188 47.92 48 61.24 11.5 52 170 176
