Abstract
Natural human locomotion via shoulder girdle is performed by a motion denoted as a spontaneous crawling. Way of swimming crawl is similarly organised in guadrupedal crossed locomotion pattern.
Natural locomotion pattern similar to spontaneous crawling should in postrehabilitation locomotion regime positively influence the return of a patient to ordinary life. 12 probands acquired by intentional selection. Individuals were ages 19 to 25 years, studying physical education and sport, 6 men and 6 women.
The level of motion abilities corresponded with test requirements in Charles University in Prague, Faculty of Physical education and Sport. The Methods was used Surface polyEMG with videorecord.
Relevant significance of recorded phenomenon was determined on 70%, 80% and 100% level in 10 evaluated probands. High rate of similarity of the work of the crucial muscle making propulsion - m. latissimus dorsi was observe.
The differences concerned the muscle working in quadrupedal locomotion primarily against gravitation - m. pectoralis major and the muscle contolling trunk torsion and connecting the trunk with pelvis - m. obliquus abdominis externus. Based on the comparative analysis of spontaneus crawling and the way of swimming crawl we may recommend the strengthening the mm. latissimi dorsi and mm. obliqui abdomini externi and on the contrary, do not recommend the strengthming of the anti-gravitation muscle connected in lomotion via shoulder girdle - mm. pectorali major.
