The signal intensity of the quadriceps femoris muscle after eccentric exercising was compared with that of the same muscle before exercising.
Squatting is well known for causing high levels of quadriceps femoris EMG activity compared to other lower limb exercises (Schwanbeck et al., 2009; Wilk et al., 1996).
In addition, the entire quadriceps femoris muscle, the target tissue with the site of injection, from the treated left hind limb (containing the marked area of injection site), and the untreated right hind limb from all animals (control and 3 dose groups at 48 hours, 28 days, and 63 days after treatment) were collected in formalin for fixation, histologic processing, and microscopic examination.
Q angle is the acute angle on the point where quadriceps femoris axis and patellar tendon axis intersect (Livingston,1998).
A MMT score of the iliopsoas muscle, the quadriceps femoris, and the tibialis anterior did not change.
Autophagy and mitophagy in skeletal (quadriceps femoris) and cardiac (left ventricle) muscles were analyzed by Western blotting of tissue extracts with antibodies against LC3 (microtubule-associated protein 1 light chain 3), p62 (SQSTM1, sequestosome), and BNIP3 (BCL2/adenovirus E1B 19 kDa protein-interacting protein 3).
Multipath NMES is potentially appealing for this population also because of the excellent compliance for use at home (better than conventional NMES) [30], but the manufacturers should seriously consider the options to (1) increase the maximal current output from 70 mA to at least 100 mA to allow larger improvements in current intensity (and thus evoked force) within and between sessions and (2) extend the stimulation technology to muscle groups other than the quadriceps femoris (e.g., glutei, hamstrings) [21].
Activity induced enthesopathy was present in 4.20% of patients with bilateral quadriceps femoris enthesopathy present in 6 cases followed by 2 cases of right quadriceps femoris enthesopathy.
In backward pedaling within 45[degrees] of knee flexion, the patella has the greatest effect as a pulley, maximizing the moment arm of quadriceps femoris, biomechanically at this range the muscle is capable of generating the greatest torque which improves the muscular strength.
