However, the effects of static stretching on the functional H:Q ratio, which uses eccentric hamstrings muscle actions, have not been investigated. This study examined the acute effects of hamstrings and quadriceps static stretching on leg extensor and flexor concentric peak torque (PT), leg flexor eccentric PT, and the conventional and functional H:Q ratios. Twenty\u2010two women (mean \u00b1 SD age=20.6 \u00b1 1.9 years; body mass=64.6 \u00b1 9.1\u2003kg; height=164.5 \u00b1 6.4\u2003cm) performed three maximal voluntary unilateral isokinetic leg extension, flexion, and eccentric hamstring muscle actions at the angular velocities of 60 and 180\u00b0\/s before and after a bout of hamstrings, quadriceps, and combined hamstrings and quadriceps static stretching, and a control condition. Two\u2010way repeated measures ANOVAs (time \u00d7 condition) were used to analyze the leg extension, flexion, and eccentric PT as well as the conventional and functional H:Q ratios. Results indicated that when collapsed across velocity, hamstrings\u2010only stretching decreased the conventional ratios (<jats:italic>P<\/jats:italic>&lt;0.05). Quadriceps\u2010only and hamstrings and quadriceps stretching decreased the functional ratios (<jats:italic>P<\/jats:italic>&lt;0.05). These findings suggested that stretching may adversely affect the conventional and functional H:Q ratios.<\/jats:p>","DOI":"10.1111\/j.1600-0838.2011.01348.x","type":"journal-article","created":{"date-parts":[[2011,6,15]],"date-time":"2011-06-15T12:03:22Z","timestamp":1308139402000},"page":"38-45","source":"Crossref","is-referenced-by-count":37,"title":["Acute effects of static stretching on peak torque and the hamstrings\u2010to\u2010quadriceps conventional and functional ratios"],"prefix":"10.1111","volume":"23","author":[{"given":"P.
