Reviewer 1 Report
The main aim of the study „Loaded 5 Sit-to-Stand test to determine the force-velocity relationship in older adults: a validation study“ is to investigate the feasibility and validity of the loaded 5STS test compared to the gold standard for the assessment of F0, V0, Pmax, and Vopt through the F-v profiling in older adults. The second aim was to investigate the relationship between F0 and Pmax, as measured with both loaded 5STS and gold standard approach, with clinical markers of muscle mass and strength.
The study is interesting. I would like to appretiate the efforts of the authors. However, some information is missing in the article, some facts need to be explained and add:
Line 105, 106, 109, 110: The methodological correct would be for participants to be randomly divided into two groups, each group should take the tests in reverse order. I recommend that you complete within the limits of work.
Line 132, 133: Has this test been used in this version before? If so, I recommend writing a citation.
Line 130, 131: Is 5 minutes of recovery enough for these participants?
Line 371, 372 (Table 2): I recommend to indicate significant results in the table.
