Skeletal muscles are composed of contracting muscle fibers that make movement possible. Muscle contraction also plays a role in how a person sits and stands – in other words, their posture. Muscles also affect joint stability, heat production, and maintenance of body temperature.
Interestingly, a skeletal muscle is not just a muscle but an organ as well. They contain many components including muscle fibers, connective, nerve, and blood or vascular tissues.
Muscles vary in size from the large ones in the back and thigh to much smaller muscles in parts of the body such as the middle ear.
Fast facts on how long it takes to build muscle:
- Muscle growth from resistance training exercises depends on several factors and can take weeks or months.
- When starting any exercise program, it is essential to speak to a doctor about past or current injuries and other health considerations.
- Deciding the best way to build muscle depends on a person’s goals.
A number of factors can affect how long it takes to build muscle, including the type of exercsie performed.
A common question when a person starts exercising is how long does it take to build muscle, and the answer can be a complex one.
As we age, muscle mass and strength decrease – especially in men, who are noted to lose muscle mass at a faster rate than women of the same age.
That said, the more muscle that is present when starting an exercise programme, the more changes will be seen during training.
Muscle response to resistance training is different in men and women for many reasons. Factors may include body size, composition, and different hormones.
One study that compared muscle strength in men and women showed that not only do women have shorter muscle fibers, which account for a decrease in strength, but strength differences may also be due to lean tissue distribution.
