| Term | Definition |
|---|
| Health | a state of physical and emotional well being |
| Fitness | a combination of aerobic capacity muscular strength and muscular endurance that enhances health and quality of life. |
| Wellness | conscious and deliberate approach to advanced state of physical psychological and spiritual health. |
| Overload | a greater load than normally experienced, used to coax a training effect from the body. |
| Progression | training program which the load, demand on the body, is increased as the body adapts and improves. |
| Specificity | the type of training undertaken must relate to the desired results |
| Frequency | how often |
| Intesity | how hard |
| Time | duration |
| type | aka mode |
| Heart rate | frequency of contraction, from pulse rate |
| Stroke volume | volume of blood pumped from ventricle during each contraction of the heart. |
| Cardiac output | olume of blood pumped by the heart each minute. Ml/min |
| Oxygen consumption | the amount of oxygen necessary to accomplish given work load Expressed as Vo2 |
| *direct *indirect | Measurement of aerobic capacity |
| vo2 max tested by | 1.5 mile run |
| vo2 expressed by | mg/kg/min during max effort |
| 1 met | 3.5ml/o2 amount of o2 required per minute under resting conditions |
| Fire fighting requires __ mets | 12-14 (45 ml/kg/min) |
| Environmental factors | increase physical stress |
| 3 types of muscle | smooth cardiac skelatal |
| Factors that influence flexibility | Heredity, age, sex, activity level, structual limits |
| Best type of stretch | Static |
| Bouncing stretch | Ballistic |
| Static | Slow stretch |
| ATP | the immediate usable form of chemical energy needed for cellular funtion. |
| ATP-PC | occurs at the start of the activity regardless of intensity |
| Anaerobic glycolosis | energy produced anaerobically, occurs within the cell with the liberation of lactic acid as a metabalic by product, activities 1-3 mins |
| Aerobic glycolosis | a metabolic pathway that occurs in the mitochondria with the breakdown of glucose in the presence of oxygen |
| Strength | the maximal force that can be exerted in a single voluntary contraction |
| Endurance | the ability of the muscle to persist, to resist change |
| Flexability | the range of motion around a joint |
| isometric | no movement in the joint or muscle used for static strength |
| isotonic | movement through a range of motion for dynamic strength. |
| Isokinetic | equal or same resistance |
| MVC | max voluntary contraction, the maximal weight that can be lift one, the same as 1 rep/ max |
| aerobic capacity increases until early 20's -Active | 4% |
| aerobic capacity increases until early 20's - inactive | 8% |
| The Aerobic training effect | the adaptation to the overload imposed by an aerobic exercise program |
| Strength lift | 80-90% mvc |
| endurance lift | 30-60 mvc (best for FF's |
| Mitochandria | powerhouse of the cell |
| Static stretching delays soreness | 24-48Hrs |
| Heart is __ type of pump | double |
| Right side of heart pumps to | the lungs* is low in o2 |
| Left side pumps to | the body* is high in o2 |
| valves | keep the blood flowing in the proper direction |
| 2 atirioventricular valves | Tri-cuspid, Bi-cuspid |
| vascular system | includes arteries, veins and capillaries |
| arteries | take blood away from the heart toward the body and are thicker than veins, they pass over joints and pressure points |
| aorta | major artery which comes from heart |
| veins | bring blood back to the heart |
| Capillaries | are one cell thick in size, carry o2 to cells and waste products away from cells |
| Coronary arteries | network of arteries which supplies blood to the myocardium |
| Ischemia | a local decrease in blood supply |
| Stenosis | constricting or narrowing of blood vessel |
| Hypoxia | lack of o2 due to ischemia |
| Diffusion | is the movement of molecules from an area of higher concentration to an area of lower concentration |
| the conductive system | spreads electrical currents through the heart muscle, recording of these currents= EKG |
| Excitability | the ability for the cell to reach a threshold in response to a stimulus |
| conductivity | the ability for the cell to carry stimulus from cell to cell |
| contractility | ability to shorten |
| Automanticity | 1. the ability for the cell to function as a pacemaker without an external stimulus |
| Pulmonary system's purpose | gas exchange |
| Risk factors associated with heart disease | heredity, gender, age65+,smoking, high cholesterol, hypertension, physical inactivity, diabetes, obesity, stress |
