| Herniated Disk | The soft nucleus of the spinal disk protrudes through a small tear in the surrounding tissue; also called prolapse. |
| Lordotic Curve | The normal inward curvature of the cervical and lumbar spine that is necessary for good posture and body mechanics. |
| Kyphotic Curve | The normal outward curvature of the thoracic spine that is necessary for good posture and body mechanics. |
| Neutral Spine | Proper position of the spine to maintain a normal lordotic curve. The spine has neither too much nor too little lordotic curve. |
| Posture | The relationship of body parts, whether standing, lying, sitting, or moving. The relationship of body parts that allows you to function most effectively, with the least expenditure of energy and with a minimum amount of strain on muscles, tendons, ligaments, and joints. |
| Referred Pain | Pain that appears to be located in one area, though it actually originates in another area. |
| Scoliosis | A lateral curvature with some rotation of the spine; the most serious and deforming of all postural deviations. |
| Anaerobic Exercise | Exercise performed at an intensity so great that the bodys demand for oxygen exceeds its ability to supply it. |
| Ergogenic Aids | Substances, strategies, or treatments that are theoretically designed to improve performance in sports or competitive athletics |
| Hyperkinetic conditions | Condition caused by too much physical activity and/or insufficient rest |
| Interval training | A training technique often used for high-level aerobic and anaerobic training; technique uses repeated bouts of activity followed by rest to maximize the quality of the workout. |
| Lactic Acid | Substance that results from the process of supplying energy during anaerobic exercise; a cause of muscle fatigue |
| Plyometrics | A training technique used to develop explosive power. Referred to as speed-strength training in Eastern Europe and the former Soviet Union, where it originated. It consists of concentric isotonic contractions performed after a pre-stretch or eccentric contraction of a muscle. |
