Glossary of Water Aerobics Terms

1. Abduction - movement of the bone away from the central line of the body.
2. Adduction - movement toward the central line of the body.
3. Aerobic - exercise with oxgeyn.
4. Anaerobic - exercise without oxgeyn.
5. Body Alignment - how the torso, limbs, spine,sholders are all in proper alignment. ie. ear over the shoulder over the hips or the knee over the ankle.
6. Body Composition - the percentage of body fat to lean body mass.
7. Buoyancy - the body being suspened in water.
8. Cardiovascular - the function pertaining to the utilization of oxygen by the body through use of the heart, lungs and the circulatory system.
9. Charlie Horse - muscle cramp
10. Contraindication - An activity thtat should not be performed in general exercise classes.
11. Dehydration - excessive loss of water from the body.
12. Dorsiflexion - Bending the ankle upward.
13. Eddy Resistance - the drag that happens as the body is moved through the water. Resistance equipment, and bent limbs will add to the eddy resistance
14. Extention - (straightening) - increasing the angle between bones or body parts; return from flexion.
15. Flexibility - Joint range of motion.
16. Flexion - Movement that brings two body parts closer together (bending).
17. Frontal Resistance - the resistance caused by the surface area pushed through the water.
18. Hyperextension - straightening a joint past it's normal position
19. Hyperflexion - bending a joint more than normal
20. Hyperventilation - Over breathing - forced, rapid, or deep breathing
21. Isometric Exercise - consists of static contractions in which the muscle is unable to change length because of magnitude of the resistance.
22. Lateral - movement to the side.
23. Lean Body Mass - composed of bone, muscle, organs and body fluids.
24. Lever - a limb that transmits and modifys force or motion when forces are applied at two points and turns about a third
25. Maximum Heart Rate - the greatest number of times per minute the heart is capable of beating.
26. Minimum Working Heart Rate - the lower end of the target zone. The minimum number of times the heart should beat during exercise for cardiovascular training to take place.
27. Muscle Endurance - the ability to sustain activity for longer periods of time.
28. Optimum Working Heart Rate - the ideal number of heart beats per minute for cardiovascular training to take place.
29. Perceived Exertion - exercise is more accurately done on how hard you FEEL like you're exercising than it is on heart rates.
30. Plantarflexion - bending the ankle downward.
31. Pronation - movement of the forearm from a palms-up to a palms-down position.
32. Prone Position - laying face down.
33. Range of Motion - the term refers specifically to the angle of movement allowed by a joint when one of it's bony levers or body segments moves from its neutral position to its potentional.
34. Resting Hear Rate - the numbers of times per minute the heart beats when the body is at rest.
35. Shin Splints - term for the pain felt on the front and inside of the lower leg due to inflamed muscles and/or tendons.
36. Side Stitch - pain in the side
37. Soft Joints - keeping your joints slightly bent.
38. Static Stretching - is streching a musle for a period of time making it less likely to tear the soft tissue.
39. Supination - movement of the forearm from a palms-down to a palms-up position.
40. Supine Position - laying face up.
41. Talk Test - if you can't talk then you are exercising too hard.
42. Target Zone (Working Heart rate Range) - the range withing which an individual needs to work for aerobic training to take place.
43. Thermal Adjustment - adjusting the body to the water temperature
44. Toning - tightening or firming of the muscles.
45. Valsalva Maneuver - this is where a person holds their breath and strains.
