POOR ECCENTRIC HAMSTRING STRENGTH. Many training programs focus solely on training the concentric contraction of the hamstrings while often neglecting the development of eccentric strength. While concentric strength is important for force production, development of eccentric strength is critical for force absorption. ce performance horses WebCo-contraction of the gastrocnemius and hamstrings muscles produced strains that were higher than those produced by the isolated contraction of the hamstrings muscles. At 15° and 30° of knee flexion, the co-contraction strain values were less than those produced by stimulation of the gastrocnemius muscle alone.
