Phosphagen - Study guides, Class notes & Summaries

Aim of Crossfit - broad, general and inclusive fitness Prescription - constantly varied, high intensity, functional movement Functional movement - load, distance and speed Diet - lays the molecular foundations for fitness and health. Metabolic Conditioning - builds capacity in each of three metabolic pathways, beginning with aerobic, then lactic acid, and then phosphocreatine pathways Gymnastics - establishes functional capacity for body control and range of motion. Weightlifting and thr...

Which of the following substances regulates muscle actions? potassium calcium troponin tropomyosin calcium Which of the following substances acts at the NMJ to excite the muscle fibers of a motor unit? acetylcholine ATP creatine phosphate serotonin acetylcholine When throwing a baseball, an athlete's arm is rapidly stretched just before throwing the ball. Which of the following structures detects and responds to that stretch by reflexively increasing muscle activity?...

bioenergetics - the flow of energy in a biological system; the conversion of macronutrients into biologically usable forms of energy catabolism - the breakdown of large molecules into smaller molecules catabolism - associated with the release of energy anabolism - synthesis of larger molecules from smaller ones exergonic reaction - energy-releasing reactions that are generally catabolic endergonic reaction - require energy and include anabolic processes and the contraction of musc...

Explain how CrossFit's definition of fitness and health differ from conventional definitions. Correct Answer: We don't specialize. We don't focus on one aspect of fitness at a time, we raise all levels of fitness equally. Define CrossFit Correct Answer: A core strength and conditioning program define and calculate power Correct Answer: "Time rate of doing work" at crossfit, "power" is the undisputed king of performance hard and fast force X(times) distance/(divided by) time...

health-related vs skill-related fitness correct answers health-related: muscular strength and endurance skill-related: muscular power acute responses to resistance training correct answers neurological adaptations - EMG amplitude increases and number of motor units increases until fatigue sets in muscular adaptations - metabolites build-up, and fuel substrates start to deplete. increased hydrogen ion concentration due to dissociation of lactic acid, increased inorganic phosphate conce...

Training session correct answers series of workouts completed in succession in the same block of time on a single day Training program correct answers collection of training sessions organized into weeks, months and years that is associated with certain goals Needs Analysis correct answers -analysis of sport: physiologic needs, biomechanic needs, injury analysis -analysis of athlete Analysis of Sport: physiological needs correct answers -first identify predominant energy source (phosph...
