Signorile et al. (2002) also compared the wide grip pronated lat pull - down and reported significantly greater latissimus dorsi muscle activity than both the neutral and
supinated conditions.
Not exact matches
Four
conditions were investigated including pronated and
supinated grips performed with a wide grip (equal to the distance between the hands in the anatomical position) or narrow shoulder width grip.
They found that lower trapezius muscle activity was greater during the pronated pull - up compared with the
supinated (56 % vs. 45 % of MVIC)
condition.
Overall, therefore, the research appears to indicate that performing the lat pull - down with a pronated grip produces greater latissimus dorsi activity than narrow,
supinated and neutral grip
conditions.
