Getting Seniors Back on Their Bicycle; a Pretest-posttest Case-control Study on the Improvement of Bicycle Balance Control

This outcome variable will be obtained from a questionnaire that evaluates participants' bicycle BC skills and confidence while riding on the public roads. For each of three environments (without traffic, little traffic, busy traffic), participants must indicate what applies to them: (1) "I did not ride my bicycle here", (2) "I rode my bicycle here, but I try to avoid it", and (3) "I rode my bicycle here without problems". The answers to every question/environment were converted into a score by assigning 0, 1, and 2 points to the respective options. Summing these scores over the three questions/environments results in a number between 0 and 6, which is the outcome variable.

The 1minFTP is the highest power a participant can maintain for one minute while cycling at 60 revolutions per minute (RPM). The 1minFTP was assessed by having participants monitor their breath after a one-minute effort at some power level: if the participant can say only a few words at a time (a proxy for reaching the ventilatory threshold), the 1minFTP is reached.
