Abstract:
Two studies were conducted to assess whether indoor video-assisted cycling influenced a person's quality of exercise (subjectively and quantitatively), compared to indoor cycling alone. In the first study 12 recreationally active subjects completed an initial test of VO 2 max, and three randomized trials of cycling at 70% VO 2 max (35 min.) watching a commercial cycling tape (cycle video), a test pattern displayed on the ergometer screen (blank video), or no video. Subjects' ratings of perceived exertion (RPE) and Affect were recorded, and heart rate and oxygen consumption (VO 2 ) were measured during testing. The second study required 12 different subjects first to complete an assessment of VO 2 max and then two randomized trials (cycle video and no video) on a cycle ergometer where they freely set the intensity of their own exercise. Measurements of VO 2 , heart rate, blood lactate, power output, RPE, and Affect were recorded during testing. Results of Exp. 1 indicated that subjects' perceived effort equally between the two conditions, yet reported significantly ( p 〈 .05) higher affect at 25 and 35 min. of cycling during the cycle video condition than no video condition. Results of Exp. 2 indicated that despite similar levels of blood lactate, subjects exercised at a significantly higher intensity during the cycle video condition compared to no video condition, with a higher VO 2 and heart rate. The data support the use of indoor exercise videos to improve the exercise experience and also to increase the physiological demands of indoor exercise.
