WT10m_M0_M1_M2_M3_wide.csv

(cave: this test was not correctly performed due to insufficient instructions, i.e., the test included in total only 10 m instead of 14 m walking, and it is not clear if the noted unit of measure is meters or metres/second (sheet vs. instruction), and a participant ran. Finally, the values range between 2.7 and 12.8, which is implausible. Thus, this test should be excluded from further analysis.)
