Correlated with Enjoyment of Use in Trained Runners: A User-Centered Approach,"
Applied Ergonomics, Vol. 74, pp. 37-40

Description: Repeated Measures (block) experiment with 4 treadmill models (treatments), 
57 trained runners (subjects/blocks), and 7 responses. No attempt should be made to
conduct multivariate analysis. Data generated to preserve means, standard deviations, ANOVA.
Treatments (treadmill models): 1=Life Fitness, 2=Precor, 3=Matrix, 4=Technogym
Responses (all measured on a visual analog scale: 
1. Functionality/Usability of running surface (Low=Very Unpleasant/High=Very Pleasant)
2. Learnability of equipment controls (Low=Very Difficult/High=Very Easy)
3. Reliability of treadmill for stability and safety (Low=Very Unstable/High=Very Stable)
4. Physical interaction with machine (i.e. comfort,position,noise) (Low=Poor/High=Good)
5. Readability of console data (Low=Extremely Complex/High=Extremely Simple)
6. Aesthetic Appeal (Low=Very Unpleasant/High=Very Pleasant)
7. Enjoyment of Use (Low=Very Unpleasant/High=Very Pleasant)
