Analysis of postural balance between two aquatic sports using vertical vs. horizontal body position

Research output: Contribution to journalArticlepeer-review


Abstract. – OBJECTIVE: This study aims
to analyze and compare the postural balance
between two aquatic sports where vertical vs.
horizontal body positions (i.e., windsurfing vs.
swimming) are key techniques for both sports.
windsurfers and eight swimmers agreed to participate in this study. Each of the assessments
was a 2D kinematic analysis of frontal and/or
sagittal balance (i.e., in bipedal and/or unipedal
stance) of the center of mass velocity on wobble board (Single Plane Balance Board) on hard
and/or soft surface. Kinematic analysis was performed in 2D using two action-cams. Data were
digitized using the video-based data analysis
system SkillSpector.
RESULTS: The results showed that the
ANOVA, with repeated measures on 1 factor,
showed a significant difference (pin all variables and in the interaction between
ground (i.e., hard and foam) and group (pin all tests in sagittal plane. Furthermore, for the
ground*group interaction, a study (i.e., paired
t-test) of the difference between balance (i.e., in
frontal and/or sagittal plane) on hard and soft
ground for each group showed that windsurfers
had no difference in body sway in frontal and/or
sagittal plane between hard and soft surface in
bipedal stance.
