4.6: Why Muscle Matters — Flashcards
| Front | Back |
|---|---|
| Exercise | Movement of the body that uses energy that is planned, structured, repetitive, and purposive. |
| Fitness | The ability to do daily tasks with energy and without getting tired. |
| Insulin | A hormone made by the pancreas that helps glucose from food get into your cells to be used for energy. |
| Body Composition | Measurements of the body's components, including total mass, fat mass, percentage fat, lean soft tissue, and fat-free mass. |
| Muscle-Strengthening (activities) | Exercises that make muscles do more work than usual by holding against an applied force or weight. |
| Bone-Strengthening (activities) | Activities that produce an impact or tension force on the bones. |
| Muscular Strength | How much force you can exert or how much weight you can lift. |
| Muscular Endurance | How many times or how long you can exert force without getting too tired. |
| Circuit Training | A form of body conditioning combining a resistance training set followed immediately by an aerobic exercise interval. |
| Repetition | The number of times a person lifts a weight, for example. |
| How many muscles are in the human body? | Over 600 muscles. |
| Example of a muscle that works independently of your mind | The heart. |
| Why is building muscle important? (list at least 3 reasons) | Grow stronger and move more efficiently, strengthen bones, decrease injury risk, improve heart/lung health, promote insulin sensitivity, help weight management, reduce anxiety/depression symptoms. |
| Recommended frequency for muscle/bone-strengthening activity | At least 3 days per week, as part of 60 minutes of daily physical activity. |
| Trapezius | Muscle located around the neck; strengthened with shrugs. |
| Quadriceps | Muscle located at the front of the thigh; strengthened with squats. |
| Hamstrings | Muscle located at the back of the upper leg; strengthened with lunges. |
| Gastrocnemius | Calf muscle located at the back of the lower leg; strengthened with calf raises. |
| Relationship between muscular strength and endurance | They are related—if one increases, so does the other; most exercises build both simultaneously. |
| Why do both wide-grip and close-grip push-ups? | Doing both types helps keep muscle growth in the upper body balanced, since hand placement changes which muscles work hardest. |
