1. Results (cont’d) Results INTRODUCTION: Body Mass Index (BMI) is the height to weight measurement used to determine if a person is at a healthy body composition. Research shows that students who drive 16 minutes or longer to campus are 64% more likely to have a BMI of 25 or over. Fitness of an individual also depends on other variables such as relative maximal oxygen consumption (VO2max), maximal heart rate, time of exercise, and percent body fat. PURPOSE: The purpose of this study was to evaluate the fitness of male commuters and non-commuters and determine any differences. METHODS: Five male non-commuters (age 20.2 + 1.30 yrs) and five male commuters (age 22.0 + 0.00 yrs) were recruited to be included in this study. Each subject had their body mass index (BMI) and percent body fat (%BF) assessed. Each subject also performed a VO2max test on the treadmill with increasing speed and elevation until exhaustion. During each test, heart rate (HR), rate of perceived exertion (RPE), and time of exercise were recorded along with relative maximal oxygen consumption (VO2max). RESULTS: The percent body fat calculated using bioelectrical impedance analysis (BIA) was 16.4 ± 12.1% (N) and 20.4 ± 7.0% (C). The BMI (N: 27.66 ± 9.74; C: 25.14 ± 3.26) and time of exercise (N: 11:05 ± 2:02; C: 10:51 ± 1:20). The maximal values: HR (N: 191.8 ± 9.1 bpm; C: 189.4 ± 7.1 bpm); RPE (N: 16.4 ± 0.9; C: 16.8 ±1.9); and relative VO2max (N: 42.98 ± 9.56 ml/kg/min; C: 41.16 ± 6.47 ml/kg/min). There were no significant differences in all variables tested (p > 0.05). The p-values were as follows: HR (p = 0.65); RPE (p = 0.69); BMI (p = 0.61); %BF (p = 0.55); relative VO2max (p = 0.73); time of exercise (p = 0.84). CONCLUSION: The results of this study indicate that male non-commuters are not more fit than male commuters. There was a difference between the two groups in that HRmax was higher, RPEmax was less, time of exercise was longer, BMI was higher, relative VO2max was higher, and %BF was less for non-commuters but not to a significant degree of difference.

Table 1: Subject’s Demographics Non-CommutersCommuters Age 20.20 ± 1.30 22.00 ± 0.00 Weight 191.20 ± 79.69 167.00 ± 35.63 Height 69.20 ± 2.39 68.00 ± 3.87 According to this study, the results showed that although there was a difference in fitness between those who live on campus and those who drive to campus, there were no significant differences between the two groups. In terms of further research, a larger subject pool as well as the use of a diet and exercise survey may help further understand the effects of driving to campus. Further research should also take into consideration male and female fitness so that the overall fitness of commuters and non- commuters of a college is measured. Participants 10 subjects (5 male non-commuters, 5 commuters) Measurements BMI Body Fat Percentage Heart Rate Rating of Perceived Exertion Time of exercise Relative VO2max (ml/kg/min) Procedure Subjects height and weight were measured using the Detecto® scale and was used to calculate height and weight using the formula: Subjects body fat percentage was calculated by using the Tanita® TBF-612 Body Fat Monitor/Scale. Procedure (cont’d) Subjects ran on a Quinton™ Q-Stress™ TM65 treadmill using the ParvoMedics TrueOne Metabolics System to measure relative VO 2 max and time of exercise. The VO 2max test protocol used was the Bruce protocol with a 5 minute rest period before exercise so the anticipatory heart rate returned to a normal resting value. Rating of Perceived Exertion was measured using the Borg RPE Scale (6-20) every third minute of exercise. Heart rate was measured using the Polar® FT1 heart rate monitor. Subjects reported to the Cardiovascular Research Lab once. Data was analyzed by using a t-test to determine if there were any significant differences between both groups (p < 0.05). Body fat percentage calculated using bioelectrical impedance analysis (BIA) was 16.4 ± 12.1% (N) and 20.4 ± 7.0% (C). The BMI (N: 27.66 ± 9.74; C: 25.14 ± 3.26) and time of exercise (N: 11:05 ± 2:02; C: 10:51 ± 1:20). The maximal values: HR (N: 191.8 ± 9.1 bpm; C: 189.4 ± 7.1 bpm); RPE (N: 16.4 ± 0.9; C: 16.8 ±1.9); and relative VO2max (N: 42.98 ± 9.56 ml/kg/min; C: 41.16 ± 6.47 ml/kg/min). There were no significant differences in all variables tested (p > 0.05). The p-values were as follows: HR (p = 0.65); RPE (p = 0.69); BMI (p = 0.61); %BF (p = 0.55); relative VO 2max (p = 0.73); time of exercise (p = 0.84).
