Effect of gender on the quadriceps-to-hamstrings coactivation ratio during different exercises.
CONTEXT Coactivation ratio of quadriceps to hamstring muscles (Q:H) and medial to lateral knee muscles (M:L) contributes to the dynamic stability of the knee joint during movement patterns recommended during rehabilitation and important for daily function. OBJECTIVE To compare the quadriceps-to-hamstring and medial-to-lateral knee muscles' coactivation ratios between men and women during the ...
متن کاملGluteal muscle activation during common therapeutic exercises.
STUDY DESIGN Experimental laboratory study. OBJECTIVES To quantify and compare electromyographic signal amplitude of the gluteus maximus and gluteus medius muscles during exercises of varying difficulty to determine which exercise most effectively recruits these muscles. BACKGROUND Gluteal muscle weakness has been proposed to be associated with lower extremity injury. Exercises to strengthe...
متن کاملTemporal coactivation of abdominal muscles during dynamic stability exercises.
The purpose of this study was to determine abdominal muscle temporal responses to a leg-loading exercise protocol and if differences exist between those able and unable to minimize lumbar-pelvic motion during this protocol. The focus was a supine bilateral leg-loading task that incorporated a slide (level 4) or no slide (level 5). Thirty-three healthy subjects (mean age 24 years) completed the ...
متن کاملQuadriceps and hamstrings fatigue alters hip and knee mechanics.
Neuromuscular fatigue exacerbates abnormal landing strategies, which may increase noncontact anterior cruciate ligament (ACL) injury risk. The synergistic actions of quadriceps and hamstrings (QH) muscles are central to an upright landing posture, though the precise effect of simultaneous fatigue of these muscles on landing and ACL injury risk is unclear. Elucidating neuromechanical responses t...
متن کاملQuadriceps and hamstrings muscle dysfunction after total knee arthroplasty.
BACKGROUND/RATIONALE Although TKA reliably reduces pain from knee osteoarthritis, full recovery of muscle strength and physical function to normal levels is rare. We presumed that a better understanding of acute changes in hamstrings and quadriceps muscle performance would allow us to enhance early rehabilitation after TKA and improve long-term function. QUESTIONS/PURPOSES The purposes of thi...
