Bones are strong due to calcium. This is a strong reason for feeding children with the products which are rich of calcium: i.e. milk, cheese, cottage cheese.
Fibrocartilage
Leaves are designed to last only a short time so a secondary xylem and phloem supply is not needed. These chemicals offer a strong support system that is not needed in the leaves, just the trees.

Many Motor Units
To accomplish a strong contraction in muscles, it is important to activate the motor units within the muscles. This can be done through proper nerve stimulation, which is provided by the brain and nervous system. Additionally, having sufficient muscle strength and adequate fuel supply, such as ATP, are necessary for a strong contraction.
Myotonia means delayed relaxation after a strong contraction.
Pelvic Floor Grading SystemsMuscle Strength Grading: Modified Oxford GradingGrade 0: No discernible contractionGrade 1: Very weak contraction, a"flicker". Slight change in tension only.Grade 2: Weak contraction.Grade 3: Moderate contraction with some squeeze and lift ability. Clinically this is the aim. At this level continence and support start to return.Grade 4 : Good contraction; squeeze and lift against resistance.Grade 5: Strong contraction, squeeze and lift against strong resistance.Hope this helps!
Calcium is necessary for strong bones and teeth but also a key component in muscle contraction.
Absolute refractory period

one would be the amount of contractile strength that results from a muscle contraction.

It depends on the strength of the stimulus. A threshold voltage has to be reached before the nerve can be stimulated.
