JOINTS Any place where two or more bones come together is a JOINT. STRUCTURE OF A JOINT (Flash video: Body Basics Muscles and Joints) http://kidshealth.org/teen/your_body/body_ba sics/bones_muscles_joints.html TENDON: fibrous cords that connects muscle to bone CARTILAGE: flexible connective tissue that lines the surface of joints; allows smooth movement, cushion, and support. LIGAMENT: tough bands of fibrous, slightly elastic tissue that connects bone to bone HINGE Allows a back and forth movement; like hinges on a door. (Flexion / Extension) Example: Elbow, Knee BALL AND SOCKET A bone with a rounded end that fits into a cuplike cavity on another bone. (Flexion, Extension, Abduction, Adduction) Example: Hip; shoulder PIVOT One bone rotates in a ring of another bone that does not move. (Rotation) Example: Atlas/Axis (neck) GLIDING A free moving joint that provides a gliding motion limited by ligaments (Flexion, Extension, Rotation) Example: hand and foot, vertebral column Where is the sternocleidomastoid? OBJECTIVES: What are the major muscle groups in the human body? Where are the major muscle groups in the human body located? What movements are generated by the major muscle groups in the human body?

Definitions Muscular Strength ◦ The amount of force a muscle can exert. Vital to activities that involve LIFTING PUSHING __________, _____________, and ____________. JUMPING Muscular Endurance ◦ The ability of the muscles to do difficult physical tasks over a period of time without causing fatigue. AEROBIC activities Mostly used during ____________ Key Concept: all body movements depend on muscle Hypertrophy: the enlargement of muscle. SIZE NUMBER ◦ Increase in __________, NOT __________ Atrophy: the shrinking of muscle ◦ Disuse atrophy ◦ Neurogenic atrophy Methods of Improving Muscular Fitness Isometrics Pushing against an immovable object. (holding a contraction for an extended period of time) Isotonics Activity that combines muscle shortening/lengthening with repeated movement Plyometrics Exercise which forces the muscle to go from being lengthened to shortened. Pushing against a doorway, wall sit Push-ups, pull-ups, lifting weights Jumping, bounding, etc. VOCABULARY REPETITION(S) The number of ________________: consecutive times one does an exercise; usually referred to as reps. SET ________________: A group of repetitions of a specific exercise; each set of repetitions or reps is followed by a rest period before another is performed RESISTANCE ________________: A force that acts against the muscles. TRAINING FOR… SETS REPETITIONS RESISTANCE GENERAL FITNESS 2-4 8 - 12 35-60% 1RM MUSCULAR ENDURANCE 2-4 12 - 20 40-60% 1RM MUSCULAR STRENGTH 3-5 1-6 60-80% 1RM Sets x Reps @ Resistance If Johnny starts out lifting 3 x 12 @ 150 on the bench press, how could you gradually make Johnny’s workout harder over a four week period? HINT: you should not increase an individual’s resistance (weight) more than 10% per week.

Please list 3 extensors in the human body 3. Which muscle is responsible for: ◦ A. Raising the arms in 3 directions? ◦ B. Allowing you to go from sitting to standing? ◦ C. Shrugging your shoulders? ◦ D. Rotating your torso? REVIEW QUESTIONS Do you demonstrate progression? ◦ Weight, reps change? Are the exercises appropriate? Do you target the entire body – core? You can include 2 core exercises per day Back extension = upper or lower body Weight Training Workouts
