Specifically, it is approximately 1.6 times larger relative to body mass compared to chimpanzees and comprises about 18.3% of total hip musculature mass versus 11.7% in chimpanzees. [11] Its large size is one of the most characteristic features of the muscular system in humans, [ 2 ] connected as it is with the power of maintaining the trunk in ...
Myostatin-related muscle hypertrophy is a rare genetic condition characterized by reduced body fat and increased skeletal muscle size. [1] Affected individuals have up to twice the usual amount of muscle mass in their bodies, but increases in muscle strength are not usually congruent. [2]
The gluteus maximus is larger in size and thicker in humans than in other primates. [2] Specifically, it is approximately 1.6 times larger relative to body mass compared to chimpanzees and comprises about 18.3% of total hip musculature mass versus 11.7% in chimpanzees. [3]
In the tibial shaft, the mechanical and anatomical axes coincide, but in the femoral shaft they diverge 6°, resulting in the femorotibial angle of 174° in a leg with normal axial alignment. A leg is considered straight when, with the feet brought together, both the medial malleoli of the ankle and the medial condyles of the knee are touching.
Protein intakes up to 1.6 grams per kilogram of body weight a day help increase gains in strength and muscle size from resistance training. [19] Training variables, in the context of strength training, such as frequency, intensity, and total volume also directly affect the increase of muscle hypertrophy.
Muscle strength is a result of three overlapping factors: physiological strength (muscle size, cross sectional area, available crossbridging, responses to training), neurological strength (how strong or weak is the signal that tells the muscle to contract), and mechanical strength (muscle's force angle on the lever, moment arm length, joint ...

The fascia lata is the strong and deep fascia of the thigh that surrounds the thigh muscles and forms the outer limits of the compartments. Internally the muscle compartments are divided by the lateral and medial intermuscular septa. The three groups of muscles contained in the compartments have their own nerve supply: [1]
