Muscular Strength |
Muscular strength is the maximal force that a muscle or muscle group can exert during a single contraction. |
Muscle Endurance |
The ability of a muscle or muscle group to exert force against a resistance over a sustained period of time. |
Essential Fat |
Amount of body fat necessary for the maintenance of life and reproductive function (2-5% body fat for men; 10-13% body fat for women). |
Storage Fat |
Body fat that is stored in excess of essential fat; aka overweight or obesity. |
Tidal Volume |
Volume of air moved with each breath and represents the depth of ventilation. |
Stroke Volume |
Quantity of blood pumped per heart beat. |
Aerobic Glycosis |
Metabolic pathway the produces ATP in the presence of oxygen. |
Anaerobic Glycosis |
Metabolic pathway that produces ATP in the absence of oxygen. |
Heat Exaustion |
Moderate form of heart stress due to inadequate circulatory adjustments to exercise in the heat and humidity coupled with fluid loss. |
Heat Stroke |
Severe form of heat stress resulting from a complete failure of the body's heat regulation mechanism, which the core body temperature exceeding 104 degrees F (40 degrees C). |
Ventilatory Threshold (VT1) |
First threshold (VT1) occurs at approximately the first time lactate beings to accumulate, represents hyperventilation relative to VO2 and is caused by the need to blow off extra CO2 produced by the buffering of acid metabolites. VTI is approximately the highest intensity that a trained individual can sustain for one to two hours of exercise. |
Second Ventilatory Threshold (VT2) |
Occurs at the point where lactate is rapidly increasing with intensity, and represents hyperventilation even relative to the extra CO2 that is being produced. VT2 is approximately the highest intensity that a trained individual can sustain for 30-60 minutes. |
