Human Movement: Swimming Essay
To assess the chosen physiological and biomechanical parameters, the intermittent incremental protocol was the prime tool used in this study; the …show more content…
Complementarily, the 7x200m protocol allows the swimmer to begin the test with low velocity, existing a balance between the lactate production and its removal, when used to the AnT assessment. After the AnT has been reached, the anaerobic contribution is truly significant, being the exponential growth of [La-] clearly observed in the following steps. Coen et al. (2001) stated that the increments between steps are one factor of variability to which the AnT assessment is insensitive. The 30 s intervals between steps were proved to be adequate in the v determination associated to the AnT assessment (Wakayoshi et al. 1993). In the current study the swimming v in all protocols was controlled by underwater pace-markers lights on the bottom of the 25 m pool, also used to help the swimmers to keep an even pace along each step, being in accordance with the guidelines to control the workload of swimmers testing (Simon & Thiesmann, 1986).
Since Pyne et al. (2000) proposed the 7x200m protocol, several studies where conducted to assess the IndAnT using intermittent incremental protocols with 200m step lengths (Pyne et al., 2001; Fernandes et al., 2005; Fernandes et al., 2008; Fernandes et
