Flexibility - ANSWERThe ability to flex, extend, or circumduct the body's joints through their intended full range of motion without substantial decrement in limit strength. Training Progressions - ANSWERGeneral to specific Seated or lying to standing Single joint to multi joint Stable to unstable Simultaneous to alternating Slow to fast The SSC of muscle contraction driving plyometrics has three phases: a loading eccentric phase, a transitional amortization phase, and a(n) - ANSWE...

Neural Circuitry that travels outside the spinal cord - ANSWERPeripheral nervous system A sensory receptor within a muscle that detects changes in length and helps regulate contraction - ANSWERMuscle Spindle Branches of the cell body that act as receivers, collecting information from other neurons - ANSWERDendrites Muscle contraction is triggered when the following chemical neurotransmitters binds to receptors on the muscle - ANSWERacetylcholine Division of the peripheral nervous sys...

sliding-filament theory - ANSWERActin filaments at each end of the sarcomere slide inward on myosin filaments, pulling the z-lines toward the center of the sarcomere and thus contracting the muscle fiber. motor unit - ANSWERa motor neuron and the muscle fibers it innervates proprioceptors - ANSWERspecialized sensory receptors that provide the central nervous system w/ information needed to maintain muscle tone and perform complex coordinated movements. bodily awareness of kinesthetics ...

Which of the following is an example of a low-speed muscular strength test? - ANSWERbench press 1RM An athlete struggles to return to a "ready" stance after jumping for a ball. This deficiency demonstrates a need to improve which of the following components of athletic performance? - ANSWERstability Anthropometry generally includes measurements of all of the following EXCEPT - ANSWERBMI During the 300-yard (274 m) shuttle run, how far away are the lines, and how many round trips a...

Sliding Filament Theory - ANSWERActin filaments at each end of the sarcomere slide inward on myosin filaments, pulling z-lines toward the center of the sarcomere and thus shortening the muscle fiber. Muscle fiber fatigue order - ANSWERType 2a Type 2x Type 1 lactic acid - ANSWERProduced in muscle cells from the reduction of pyruvate (under anaerobic conditions) to regenerate NAD+ so that glycolysis can continue. A rise in lactic acid usually accompanies an increase in physical activity. ...

List four ways to perform resistance exercises and describe each method using examples: - ANSWER1. Isometrics: side bridges and planks 2. Free weights: barbells, dumbbells, kettlebells, stones, and sand bags. 3. Weight machines: weight stacks, weight plates, air, hydraulic fluid, and bands. 4. Calisthenics: pull ups, step ups, and push ups. With isometric exercise, strength increases only in the joint positions you work during the movement within this range of motion: - ANSWERC. 15 d...
