The Comparison Of Hamstring/Quadriceps Strength Ratio In The Dominant Versus The Non-Dominant Leg Of Elite Female Artistic Gymnasts, Marina Moure

Human Movement Studies & Special Education Theses & Dissertations

The majority of the injuries in women's artistic gymnastics occur in the lower limbs (Marshall et al, 2007). Hamstring muscle strains are prevalent in sports that involve sprinting (Ekstrand & Quillist, 1985; Orchard, 2001; Croisier et al., 2008) with a high reinjury ratio (Orchard, 1993; Orchard, 1997). Recent studies have linked an increase of muscle injury rate in the lower limbs to strength muscle imbalance between legs and the relation between the hamstring and quadriceps strength (Croisier et al., 2002; Yamamoto, 2008; Sugiura et al, 2008).
