“…Another function attributed to the vastus medialis is stabilization of the patella within the trochlear groove [ 63 , 64 , 65 ], thus, generating a medializing force vector upon the patella, which would cause its rotation when in extension [ 66 , 67 , 68 ]. The quadriceps are also active during the swing phase of running, in preparation to receive the weight load [ 69 ]. Interestingly, women seem to have increased quadriceps activation when performing sports activities [ 70 ], which can substantially contribute to physiologically significant [ 71 , 72 , 73 ] changes in muscle strength between the sexes [ 71 ].…”

Each year, 50% of runners suffer from injuries. Consequently, more studies are being published about running biomechanics; these studies identify factors that can help prevent injuries. Scientific evidence suggests that recreational runners should use personalized biomechanical training plans, not only to improve their performance, but also to prevent injuries caused by the inability of amateur athletes to tolerate increased loads, and/or because of poor form. This study provides an overview of the different normative patterns of lower limb muscle activation and articular ranges of the pelvis during running, at self-selected speeds, in men and women. Methods: 38 healthy runners aged 18 to 49 years were included in this work. We examined eight muscles by applying two wearable superficial electromyography sensors and an inertial sensor for three-dimensional (3D) pelvis kinematics. Results: the largest differences were obtained for gluteus maximus activation in the first double float phase (p = 0.013) and second stance phase (p = 0.003), as well as in the gluteus medius in the second stance phase (p = 0.028). In both cases, the activation distribution was more homogeneous in men and presented significantly lower values than those obtained for women. In addition, there was a significantly higher percentage of total vastus medialis activation in women throughout the running cycle with the median (25th–75th percentile) for women being 12.50% (9.25–14) and 10% (9–12) for men. Women also had a greater range of pelvis rotation during running at self-selected speeds (p = 0.011). Conclusions: understanding the differences between men and women, in terms of muscle activation and pelvic kinematic values, could be especially useful to allow health professionals detect athletes who may be at risk of injury.

“…This results in impaired load distribution in the joint and thus further facilitates disease progression. [25] The increased joint loading and decreased shock absorption due to cartilage erosion lead to more stress on the static stabilizers of the joint causing excessive stretching of ligaments and capsule which could further contribute to increased KP, decreased ROM, and more disability. [26] However, some studies do not support the ndings of the present study, such as a study performed by Zacaron KAM et al on elderly people with knee OA reported no correlation between the pain variable and the total work of quadriceps muscle.…”

Background Knee osteoarthritis (OA) is a prevalent disabling disease among women. Quadriceps weakness is attributed to one of the causes of knee pain (KP) and disability. The study aimed to test the correlation of eccentric quadriceps torque (EQT) with 2 subscales of reduced WOMAC questionnaire (KP and physical function) and extension lag range of motion (ROM) at the knee joint in osteoarthritic women. Methods A cross-sectional design was used. A total of 70 (age 41.1 ± 7.1) female patients having grade ≤ II knee OA participated in the study. Pearson’s correlation coefficient was used to test the correlation between the independent variable (EQT) and dependent variables (2 subscales of reduced WOMAC questionnaire and extension lag in the knee). Results EQT presented a significant moderate negative correlation with the reduced WOMAC subscales (pain r = -0.489, p < 0.01 and physical function r = -0.425, p < 0.01), and low positive correlation with available ROM (r = 0.349, p < 0.01). Conclusions The self-reported symptoms of KP, physical function, and extension lag in the early stages of knee OA in women are associated with EQT. Thus designing a rehabilitation program having eccentric quadriceps strengthening exercises may improve KP and physical activities but further randomized controlled trials are needed to verify this.

“…The studies investigated patients with KOA, an ACLinjury, Arthroscopic partial meniscectomy (APM) patients and healthy subjects. During comfortable gait higher co-contraction ratios were present in the muscles of the medial side of the knee compared to the lateral side of patients with KOA [94]. Da Fonseca et al [53] showed that healthy women with sedentary behavior had a higher co-contraction ratio compared to athletic women.…”

“…Patients with knee joint instability are suggested to have a neuromuscular adaption to compensate for the instability of the joint. The amplitude of muscle activation was therefore used in 18% of all studies as objective parameter for knee joint stability, during comfortable gait ( Table 2, 11 studies) and challenged gait ( Table 3, [24,82,88,94,97], but three studies did not [36,65,76]. After perturbation training, higher vastus lateralis IL activation was observed in patients with an ACL injury [49].…”
