Sažetak
We evaluated (1) the test–retest reliability of the Wingate test conducted on a rowing ergometer, and (2) the sensitivity of this test in determining the differences in performance attained by 12- to 18-year-old rowers. Altogether, 297 male rowers aged 12.0–18.9 years (mean+s: 14.8+1.7) completed a maximal 30-s test on a rowing ergometer, and 80 rowers representing all age groups were retested after 5–7 days. No change was evident in participants’ performance in terms of mean power output (P=0.726 ; Cohen’s d=0.04), maximal power output (P=0.567 ; Cohen’s d=0.06), and minimum power output(P=0.318 ; Cohen’s d=0.11) in the second test. The intra- class correlation coefficients were high (ICC=0.973) and coefficients of variation were low (Cv = 7.3%). A series of analyses of variance were used to compare the performances among 12- to 18-year-old rowers, and age- related increases in performance were evident (P50.001 ; Cohen’s d=1.91–1.96). The age- related increases in performance were similar, although reduced, when the effects of body mass were partitioned out when using analysis of covariance (P<0.001 ; Cohen’s d = 0.82–0.85). The results suggest that: (1) the described test is reliable and can be used for maximal- intensity exercise assessment in youth rowing, and (2) it discriminates performance among 12- to-18-year-old rowers.
