Iran. 0000-0002-1503-468x Ebrahim Sadeghi Demne Journal Article 2015 12 26  The purpose of the following research was to compare the training effects on in-phase and anti-phase coordinated movements with arms and legs. Twelve female students of the Farhangian University of Isfahan (aged 22 ± 5 y) were randomly selected without any background in rhythmic sports and underwent a six-month training under supervision of a hip-hop instructor to learn and practice hip hop along with the specific tasks of the research. The participants reported to lab at first, third, and sixth months, each considered as a level of skill. Using motion analyzer, performance of four chosen exercises of in-phase and anti-phase were filmed by seven cameras. All the data were processed by programming, using MATLAB and the variable error of the participants were calculated. Afterwards, ANOVA with repeated measures was used for data analysis at significance level of P=0.05. The results indicated significant difference in variable error of performance between different levels of skills, with coordinated moves at each level being executed more firmly compared with lower levels. Study of interactive effect of the pattern, levels, and limbs showed that the variable error of anti-phase movement was more significant than that of in-phase movement in each level and both limbs. Overall, the results proved that training improves the in-phase and anti-phase movement model performance in hands and legs at the same level.   The purpose of the following research was to compare the training effects on in-phase and anti-phase coordinated movements with arms and legs.
