PURPOSE: Repeatability of simultaneous measurement of heart rate (HR) and blood pressure (BP) during a modified Ruffier’s test in compliance with the conditions for determining its reliability was examined. METHODS: 30 students of the School Master of Sports were investigated twice. The measurements were separated by a 9-day intermission. Students performed a modified Ruffier’s test with simultaneous measurements of HR and BP. Each measurement was carried out in a sitting position: at rest, immediately after the test completion and three minutes after the completion of the test. Heart rate was measured over 15 s and the result was multiplied by 4, whereas the arterial blood pressure (BP) was measured by the Korotkov method. A spring sphygmomanometer with a deflated cuff was placed on the arm of the subject tested throughout the test. The test consisted of 30 full squats performed in 30 s with the maximally flexed legs in the knees and the feet shoulder-width apart. When obligatory time of the test (30 s) was exceeded, 0.1 point was added to the outcome of the test for each second extra. The physician and the nurse simultaneously measured using the honendoscope. The data were processed by the descriptive statistics: arithmetic mean, standard deviation, correlation coefficients. RESULTS: Immediately after the exertions there were high correlations between HR and scores of Ruffier’s (0.814 and 0.879). Slightly higher values of HR on average have been recorded during the second measurement, which resulted in the increased Ruffier’s index (from 6.7 to 7.4). Likewise, systolic (BPs) and diastolic (BPd) blood pressure measured in the same conditions were correlated (0.890 and 0.932) with the Ruffier’s index. A similar trend was observed 3 minutes after the test – correlations were 0.839 and 0.750. In the Ruffier’s test verification it was found that: the higher the BPs and the BPd, the lower theRuffier’s indexes. Very low values of BPd recorded in few cases immediately after the test were responsible for the elevated Ruffier’s index. CONCLUSIONS: 1. A high level of reliability of the modified Ruffier’s test found on the basis of measurements of HR and BP allows a more accurate assessment of the state of preparation of the cardio-vascular system to the effort and provides the basis for a fair interpretation of the results of the test. 2. It is recommended to use the described modifications of Ruffier’s test for the assessment of the cardiovascular system performance in preparation for the effort, and at the same time, the health of athletes in the training process, and especially – in the qualifications of candidates to sports.
