| Abstract |
The present study aimed to analyze the correlations between the 2-minute step test (2MST) and predicted
maximal oxygen uptake (VO2max), between the predicted VO2max and lower limb strength, and between the 2MST and
lower limb strength in adult men. Methods: Thirty-one adult males participated in this study. During the 2MST, the
number of completed steps was measured. During the maximal exercise stress test (MEST), the total running time was
recorded and used to calculate the predicted VO2max. After completing the MEST, the participants reported their
perceived exertion using the Borg Rating of Perceived Exertion scale. During the isokinetic test, the maximum muscle
strength and endurance of the knee joint were measured. The correlation coefficients between the 2MST, MEST, and
lower limb strength were calculated using Pearson correlation analysis. Results: No statistically significant correlation
was observed between the 2MST, MEST, and lower limb strength (p>.05). However, a statistically significant and
moderate correlation (r=.416) was found between the predicted VO2max and peak torque flexion (PTF) (p<.05). In
addition, a statistically significant and high correlation (r=.765) was observed between peak torque extension and PTF
(p<.01). Conclusion: Future studies should include a study design that includes a patient population with diverse
demographic characteristics and a clinical physical therapy setting that requires cardiopulmonary fitness assessment.
Moreover, the results should be validated through the direct measurement of VO2max and standardized performance
guidelines for the 2MST. |
