Semper Fit Basic Fitness Course with complete verified solutions already graded A+

Define exercise physiology Exercise physiology is the science that describes, explains, and uses the body's response and adaptation to exercise training to maximum human physical potential. It includes the interaction of the heart, lungs, and muscles, and how they respond to exercise. Define optimal fitness Optimal fitness refers to the best functioning level of fitness a Marine can attain. At the optimal level, the body of the Marine functions as efficiently as it can.

Optimal fitness can be measured by accomplishing missions without undue fatigue. The ability of a muscle to contract repeatedly without fatiguing. Muscular Endurance The ability of the heart and lungs to work efficiently over an extended period of time and provide oxygen to the working muscles. Cardiopulmonary Endurance Refers to the muscular and fat make-up of the body. Body Composition The ability to move your joints comfortably through a full range of motion. Flexibility The amount of force a muscle can produce. Muscular Strength Blood is pumped to the lungs by the (blank) side of the heart and pumped to the body by the (blank) side of the heart. Right; Left Identify six adaptations of the heart and blood vessels in response to exercise. (1) The size of the heart increases making it able to pump more blood with more force. (2) The amount of blood the heart pumps with each contraction increases. This is due to a combination of an increase in the heart size and a decrease in pulse that allows more blood to enter the heart between beats. (3) There is a decrease in the resting and training heart rate. (4) The heart rate recovers to resting levels more rapidly after training has stopped. (5) More capillaries form to supply the working muscles with oxygen rich blood. (6) Blood pressure decreases. Cpl Jones participates in endurance training 3 times per week while Cpl Jefferson participates once a week. What effect may this have on both Marines' lungs. Cpl Jones' body is effectively using a large amount of oxygen better than Cpl Jefferson. The molecule that provides the energy for muscle contraction is? adenosine tri-phosphate Provides energy for endurance tasks Aerobic Provides energy for 30 to 90 seconds Anaerobic Provides energy for 6 to 10 seconds Creatine Phosphate Identify the three major benefits of warming up. (1) Increases body temperature (2) Improved range of motion (3) Prepares the heart and lungs for higher intensity exercise General Warm-up Method Increases Temperature Improves Flexibility
