Training videos are becoming increasingly popular as a way to enhance physical activity. PURPOSE: To identify the effects of an in- video trainer treadmill on mood, motivation, heart rate (HR), oxygen uptake (VO2), Rate of Perceived Exertion (RPE), Respiratory Exchange Ratio (RER), pace, speed, distance, and burned calories, then compare these effects to a treadmill workout without audiovisual input. METHODS: 17 subjects (m=9, f=8) completed two treadmill tests, one with audiovisual input, the other without. The test with audiovisual factors allowed subjects to choose from a list of 5 video courses on the NordicTrack X22i treadmill. VO2, HR, RPE, pace, RER, speed, calories and distance were recorded. Motivation and mood were collected using a feeling scale and the Physical Activity Enjoyment Scale (PACES). The feeling scale was administered in the middle and end of each test. The PACES scale was used at the end of each test. Repeated measures t-tests were used to compare differences in VO2, HR, RPE, pace, RER, speed, calories and distance. A two-factor repeated measures ANOVA was used to compare differences in the PACES and feeling scale responses. (pRESULTS: Between the tests there was no statistical difference in average VO2 (video 27.45±10.21ml/kg/min, no video 26.29±10.09 ml/kg/min, p=0.274), HR (video 139.46±22.43 bpm, no video 144.74±21.84 bpm, p=0.604), RPE (video 13.58±1.84, no video 13.22±2.00, p=0.659), pace (video 14.32±5.46 min/mi, no video 14.16±5.04 min/mi, p=0.885), RER (video 0.93±0.05, no video 0.93±0.05, p = 0.625), speed (video 4.56±1.52 mph, no video 4.43±1.43 mph, p=0.340), calories burned (video 221.92±78.92 kcal, no video 227.38±78.92 kcal, p=0.865) and distance (video 1.64±0.46 mi, no video 1.60±0.42 mi, p=0.32). Results show midpoint motivation (video 8.89±1.24, no video 7.13±2.06, p=0.004), endpoint motivation (video 8.63±1.80, no video 5.61±2.04, p=0.001), midpoint mood (video 3.53±1.26, no video 2.52±1.50, p=0.02), and endpoint mood (video 4.32±0.67, no video 3.04±1.90, p=0.001). The PACES reported differences in “Lots of Fun” (video 5.71±1.40, no video 4.29±1.57) and “Very Pleasant” (video 5.65±1.54, no video 4.24±1.64). CONCLUSION: The use of an in-video trainer treadmill produces an increase in motivation and mood compared to a similar exercise without a video.
