In half of the subjects (1, 3, 5, 6, and 8, (Table II) minimal and maximal voluntary contractions showed low amplitude and short duration polyphasic motor unit potentials; this was more frequently found in deltoid and quadriceps femoris muscles.
The plasma concentration of certain necroenzymes (LDH, CK) and the histopathological samples taken from the quadriceps femoris muscle demonstrated a significant difference between the IPO and IR groups.

The authors used 2 different graft types (hamstring and patellar tendon), there were more female patients in the strength training group than in the neuromuscular training group, and they only included patients that could walk without crutches, had full ROM, had no quadriceps femoris muscle lag, and had minimal joint effusion.

Quadriceps femoris muscle strengthening, is useful for improving functional ability, and may be particularly important for individuals who want to return to higher-demand activities such as running or other activities [16].
Objective: The purposes of this study were (1) to investigate and (2) to compare effects of isometric exercises and electrical stimulation on isokinetic strength for healthy quadriceps femoris muscle.
