| dc.description.abstract | Cardio pulmonary exercise testing (CPET) is the “gold standard” test for measuring
real time maximal oxygen uptake (VO2max) in athletes. Beep test is a commonly
used indirect field test in Sri Lankan sports settings. This study was designed to
determine the validity of beep test against the CPET for measuring cardiovascular
endurance. A cross sectional descriptive observational study was conducted by
recruiting the rowers of the national pool of Sri Lanka [n = 16, male = 5 (68.8%) and
female = 11(31.3%)], aged 24 – 34 years. Mean age of the study sample was 29.3 ±
3.1 years. Mean height, weight and BMI of the sample were 1.7 ± 4.6 m, 69.49 ± 8.95
Kg, 22.77 ± 2.31 Kgm-2 respectively. The mean VO2max obtained from the CPET
was 33.32 ± 6.69 mlKg-1min-1 for the total population with 33.64 ± 6.27 mlKg-
1min-1 in males and 33.01 ± 8.35 mlKg-1min-1 in females. In the total sample, beep
test significantly overestimated VO2max by 15.62 ± 1.25 mlKg-1min1 , in males by
17.74 ± 0.43 mlKg-1min-1 and by 12.35 ± 1.39 mlKg-1min-1 in the females. Beep
test significantly overestimated actual VO2max by a percentage deviation in the
total study population. The data were analysed using IBM Statistical Package for
Social Science (SPSS) version 23 computer software. Kolmogorov-Smirnov test was
used to determine the normality of data. Data were analyzed and described under
the descriptive measures namely mean and standard deviation. Mann Whitney test
was used to compare the variables between the male and female rowers.
Nonparametric paired samples Wilcoxon Signed Rank and Spearman’s rank order
correlation test was used. | en_US |
