Kinematics, arm coordination, and oxygen uptake in swimmers with amputations in all-out front crawl test
The aim of this study was to describe the kinematics, inter-arm coordination, and oxygen uptake of swimmers with amputations, and to verify how these parameters behave in two laps (75-100 m and 175-200 m) of an all-out 200 m front crawl test (T200). Six swimmers (four males and two females) with amputations participated (age: 30 ± 9.8 years). Anthropometric measurements were obtained, and 19 markers were placed on predetermined regions of the body for later scanning of the T200. The swimmers warmed-up and then performed the T200. The test was recorded on digital video. The images were processed (APAS software) and the videos analyzed in three dimensions (3D). Kinematic (mean stroke rate and length, swimming speed, and stroke index) and coordinative (coordination index) data were obtained from the images. During T200, oxygen uptake (VO2) was measured breath-by-breath (portable gas analyzer) and its peak value (VO2peak) was identified. Descriptive statistics and Student`s t-test for paired data were used for comparison between the laps. The performance of the swimmers assessed was 197.8 ± 24.7 s. The stroke rate, length, speed, and stroke index were, respectively, 41.0 ± 5.1 cycles/min, 1.5 ± 0.3 m, 0.98 ± 0.02 m/s, and 1.67 ± 0.59 m2/s. In general, the coordination was in capture with peak oxygen uptake of 43.6 ± 8.0 ml.kg-1.min-1. The kinematic variables and coordination did not vary between the analyzed laps.
