Training effects
Physiologic adaptations that occur as a result of aerobic exercise of sufficient intensity, frequency, and duration to produce beneficial changes in the body. The point at which regular exercise produces positive changes in the body. The physiological response of the body to regular repetitive exercise. Beneficial effects include a slower heart rate, lower blood pressure,…

Tonus
A slight, sustained muscle contraction. Continued, partial contraction of a muscle. Same as tone. The normal state of partial contraction of a resting muscle, maintained by reflex activity. The partial steady contraction of muscle that determines tonicity or firmness; the opposite of clonus.
-
Tibial torsion
Twisting of the tibia, usually associated with supinated or pronated feet. A persistent slight twist in the tibia, caused by a cramped position in the uterus. It makes the feet of young children point inwards for up to a year after they begin to walk on their own, but it corrects itself as the leg…

Tendinitis
Continuous, low-grade inflammation of a tendon, with pain on movement; can lead to partial or complete rupture of tendon. An inflammation of a tendon, especially after playing sport, and often associated with tenosynovitis. Inflammation of a tendon, usually resulting from strain or injury. Treatment includes rest and corticosteroid injections. The painful inflammation of the strong…

Target heart rate range
The rate at which the heart is beating to get the optimum aerobic effect; formula for obtaining a target heart rate equals 220 minus your age times 60%-75% is reasonable for a healthy individual to use.
-
Systolic pressure
The highest level to which arterial blood pressure rises, following the systolic ejection of blood from the left ventricle. Period of maximum arterial blood pressure. (Compare with Diastolic Pressure.) The high point of blood pressure which occurs during the systole. Systolic pressure is always higher than diastolic pressure. The higher figure in a measurement of…

Synarthrodial joint
All articulations in which bones are held together tightly by fibrous connective tissue in a nonmoveable fashion, i.e., sacroiliac.
-
Submaximal work
Workload performed below maximum heart rate; aerobic exercise is submaximal.
-
Striated muscle
Skeletal voluntary muscle that attaches to and moves the skeleton. The skeletal muscles. A type of muscle found in skeletal muscles whose movements are controlled by the central nervous system. One of three major types of muscle (the other two are smooth muscle and cardiac muscle); it makes up the major part of the body’s…

Strength
Maximum force or tension that a muscle or muscle group can produce against resistance. The ability of a muscle or muscle group to exert maximal force against a resistance in a single repetition. The amount of force a muscle produces when it contracts. The fact of being strong. The maximum force that can be generated…
