Wording for the achievement and calibration conditions in the two separated blocks of the experiment.

	Block 1: Achievement		Block 2: Calibration
1.1	Let’s start with the test.	2.1	The ergometer needs a new calibration. Like this, we can be sure about the accuracy of the ergometer.
1.2	First of all, we will do three runs with different levels of difficulty	2.2	We are again performing three runs with different levels.
1.3	With these runs, we will measure the accuracy of YOUR task PERFORMANCE.	2.3	We will perform the same as before. But this time, we will test the ERGOMETER instead of you.
1.4	We can measure your performance accurately in the course and compare it to the rest of the participants.	2.4	This time, we are measuring the accuracy of our ergometer. We have to calibrate the ergometer to make sure it measures accurately.
1.5	Here you can see your personal performance line, which we have calculated for you during the pre-test (warming-up). The optimal cadence per minute for you is 70. This line here displays the 70 rpm cadence line. Your task is to keep the cadence of 70 rpm as constant as possible around (above or below) this line. Like this, we can exactly figure out your precision of riding a specific cadence. Go for it!	2.5	Here you can see a calibration profile presented by the software of the ergometer. The cadence is 70 rpm. This line here displays the 70 rpm cadence line. Your task is to keep the cadence of 70 rpm as constant as possible around (above or below) this line. Like this, we can figure out the accuracy of our ergometer. The calibration is starting soon!
1.6	*Afterward, you will receive your individual performance log. Here, you can see an example of an ergometer protocol. The performance log will look like this. It shows your performance over time and in comparison to the other participants.	2.6	*This time, this will be the test report for the ergometer. So, we will get a log with the deviation of the ergometer from its calibration line. Roughly the same will be our performance log for the ergometer. It shows the deviation of the ergometer compared to the calibration line.

The numbering is just for illustration of the experimental manipulation; participants read a running text. *A profile example was presented to show how the participant’s profile (/the bicycle ergometer’s profile) could look at the end. Participants were told that they would receive a printed version of their own profile (/the ergometer’s profile) at the end of the study.
