... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested.

Deeb, Joseph M. and Drury, Colin G. (1992): Perceived Exertion in Isometric Muscular Contractions Related to Age, Muscle, Force Level and Duration. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 712-716.

This research was concerned with studying the development and growth of perceived effort of long-term isometric contractions as a function of muscle group (biceps vs quadriceps), of subjects with different age groups (20-29 vs. 50-59 years old) on long-term muscular isometric contractions (5 minutes) at different levels of {percent}MVC (20,40,60,80 and 100 {percent}MVC). An experiment testing 20 subjects each performing 10 conditions (two muscle groups x five levels of {percent}MVC) showed that the older age group reported Significantly higher perceived exertion at higher levels of {percent}MVC and across time. Furthermore, subjects experienced a higher and faster increase in their perceived exertion when the level of {percent}MVC and time increased.
