| Abstract: | [Purpose] The purpose of this study was to examine the effects of foot placement on thelatissmus dorsi and low back muscles activities during pull-down exercise. [Subjects] Forthis study, we recruited 10 male volunteers. [Methods] The subjects performed pull-downexercises with 4 foot placement conditions. The activities of the latissmus dorsi and L4paraspinal muscles were measured. [Results] The activities of the latissmus dorsi musclessignificantly increased in the order of conditions 1 and 2 < condition 4 < condition3. The activities of the L4 paraspinal muscles were significantly different, with theactivities of conditions 1 and 2 being greater than those of conditions 3 and 4.[Conclusion] We suggest that the selection of foot placement is an important factor forthe effective strengthening of the latissmus dorsi.Key words: Foot placement, Latissmus dorsi, Pull-down exercise |
