Environmental Ergonomics XII Igor B. Mekjavic, Stelios N. Kounalakis & Nigel A.S. Taylor (Eds.), © BIOMED, Ljubljana <strong>2007</strong> 200m in surf was correlated with surf experience (P>0.01) (from the questionnaire, Figure 2) and stroke length (P=0.08) on the swim bench. Taken together these variables accounted for 28% of the variance in the time taken for this swim. Figure 2. The relationship between surf experience and time to swim to swim 200m in the surf (N=65). The correlation analysis identified the following significant relationships: pool swim times and calm sea swim r=0.55 (P
Cold water immersion surf beaches. As experience of swimming in the surf can significantly improve surf swimming times, consideration should be given to training BLG in this skill. Swim bench tests of upper body strength and power have been reported to provide higher correlations with swimming performance than isometric upper body strength measures because of their greater specificity (Costill et al, 1985; Hawley & Williams, 1991). However, the present study did not identify any of the measures of power and strength obtained with the swim bench as particularly useful in predicting swimming performance in the pool or sea (H2 is not supported). This may have been because the bench test was much shorter than the swim times recorded. It is concluded that there is a significant skill factor in surf swimming and this may help to explain why pool swim times do not predict surf swimming performance. These findings have implications for the training and assignment of BLG. ACKNOWLEDGEMENTS The subjects and RNLI, Elizabeth McCormack, Dr. Graham Elliott.
