Subjects
Subjects were recruited from Maastricht University by means of an article in the University weekly newspaper. Because more than the required number of men responded, which allowed selection after screening for health (no high blood pressure, no diabetes mellitus, no use of medicines, no other diseases), for body mass index (for the nonobese, 20–25 kg/m2; for the obese, >25 kg/m2 [12]and for age (19–35 years), and less than the required number of women responded, the study was executed with men.
Results
Body mass index differed significantly between the obese and the nonobese (Mann–Whitney U-test, p < 0.01). Wmax was also significantly different between the obese (240 ± 38 W) and the nonobese subjects (351 ± 49 W) [F(2, 20) = 16.12; p < 0.01]. Vo2max (mL kg−1 min−1) was 58.4 ± 1.6 in the obese and 71.8 ± 1.9 in the nonobese subjects.
There were no significant differences between the results of the obese and the nonobese subjects with respect to how comfortable the subjects felt, body weight
Discussion
In general, comfort ratings representing general physical well-being, in which hunger, thirst, body temperature, and exhaustion could play a role, were sufficiently high to judge the situations as being acceptable to the subjects. In none of the observations was there any difference between the obese and nonobese groups of subjects, so the conclusions with respect to cycling versus rest apply to both groups.
After exercise, i.e., 2 h of cycling at 60% Wmax, a change in appetite was observed,
