The purpose of this thesis was to assess the validity and reliability of Cooper 12-minute running test (12MR) on the curved non-motorized treadmill (cNMT). This was conducted by comparing the Cooper 12MR performed on an indoor track and on the cNMT. The commission for this thesis came from CSE Entertainment. Testing on the cNMT was performed with the runBEAT -software developed by the commissioning party (CSE Entertainment).
Eight participants (24 years ± 7 years) took part in the testing process and performed two familiarization trials on the cNMT as well as completed the Cooper 12MR on the cNMT and on an indoor track. Grouping was implemented by a matched pair design and a randomized block design to reduce potential variables. The results were measured, recorded, and later analysed with PSPP and Excel 2022. To test the significance of the results, a two-tailed t-test with paired samples was conducted together with Pearson’s correlation. Additionally, the results and their means were compared against one another.
This thesis had three primary research questions. The first problem focused on the validity and reliability of the 12MR on cNMT. The second problem was to discover if there would be any differences regarding the challenge and physical demands between the tests, and the third problem was to determine whether cNMT together with runBEAT could be used as proper testing devices for the Cooper Test.
The results indicated a positive correlation (0,95) and are statistically significant. The participants achieved greater VO2 max estimations on track compared to the cNMT (23,9 ± 13.7%), which could indicate the more strenuous nature of the cNMT. These results are similar to previous findings of higher oxygen uptake on the cNMT. Further research could be conducted with a larger sample and the sample could be compared with direct VO2 max testing to see how well the results correlate to actual VO2 max by validating the test against a breath-to-breath analysis.
