Writing with a pencil, chewing food, walking, bending over, hopping, eating and drinking . . . well, you get the idea!
Yes; generating heat is among the functions of skeletal muscle. When skeletal muscle contract, it uses energy (from ATP) obtained from food, during the breakdown of ATP, heat is produced. Some of the heat is released to maintain body temperature and some is used to warm the muscles and surrounding tissues.
Without them you wouldn't be able to move. the skeletal system provides structure to your body.
Cardiac muscle uses aerobic respiration which is rich in myoglobulin, glycogen, and very large mitochondria that fills over 25% of the cell. Skeletal muscle only 2% of the cell. In turn makes cardiac muscle highly resistant to fatigue.

The heart muscle is different from smooth and skeletal muscles because it does not require a nerve to cause it to contract. The heart has it's own built in conduction system that cause's the automatic contraction and relaxation that is required for circulation. Smooth and Skeletal muscle whether it uses voluntary or involuntary muscle contraction all have innervation to cause the contraction. Sara, RN
The brain controls all activity in the body and uses about 20 of the body's energy.

The two main types of muscles are voluntary muscles and involuntary muscles. An voluntary muscle is a muscle that you use and work at your own will power such as your biceps or quads. In involuntary muscle is a muscle that is always being uses and you can not direct it otherwise, such as the heart.
The muscular system uses skeletal muscles to contract and relax, creating movement and supporting the body's posture. When the brain sends signals to the muscles, they contract, pulling on the bones and causing movement. This coordinated effort allows us to walk, run, and perform various activities while keeping our bodies upright.
Osteoporosis affects the Skeletal System. But the Skeletal System relies, in part, on the Digestive System and what is eaten along with the Endrocrine System which controls how the body regulates and uses minerals, hormones, etc.
Mitochondria are the "powerhouse" factories of cells, they are the main producers of ATP, which the body uses for energy. Since muscle cells are the site for lots of activity and require a lot of cellular respiration, they tend to have a lot mitochondria. Eukaryote cells of plants, protists, and fungi don't undergo as much physical activity as involved in motion that muscle cells have.
