CROSSFIT LEVEL 1 CERTIFICATE |149 QUESTIONS AND ANSWERS 2023

Definition of Crossfit constantly varied, high intensity, functional movement (also known as Crossfits prescription) What is functional movement load, distance, and speed for production of high power Define intensity power (intensity is the independent variable) Crossfit methodology: safety, efficacy, and efficiency (the 3 most important and interdependent facets to evaluate any fitness program, can be supported only by measurable, observable, repeatable data) 10 fitness domains of Crossfit: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy Define athlete a person who is trained or skilled in exercises, sports, or games requiring physical strength, agility, or stamina Define Crossfit athlete a person who is skilled or trained in strength, power, balance, and agility, flexibility, and endurance How is energy derived? aerobically when O2 is utilized to metabolize substrates derived from food and liberates energy Aerobic activity: are usually greater than 90 seconds in duration and involve low to moderate power output or intensity Ex: running on treadmill for 20 min, swimming a mile, watching TV Anaerobic activity: energy is liberated from substances in the absence of O2; these activities are of less than 2 min in duration and involve moderate to high power output intensity Ex: 100 m sprint, squatting, pull ups Anaerobic systems: phosphagen and glycolytic (lactic acid) 2 Olympic lifts: clean and jerk and snatch (they train athletes to activate more muscle fibers more rapidly more than through any other modality of training; develop an athletes explosive power, control of external objects, and mastery of critical motor recruitment patterns) Hormonal responses vital to athletic development: increased in testosterone, insulin-like growth factor, and human growth hormone Adaptive responses to exercises capable of producing a significant neuroendocrine response: mass and bone density Power time rate of doing work; also the definition of intensity What is associated with high neuroendocrine response? heavy load weight lifting, short rest between sets, high heart rates, high intensity training, short rest intervals Cross training vs Crossfit cross training is participating in several sports and Crossfit views cross training as exceeding the normal parameters of the regular demands of your sport training Functional movement: are mechanically sound and therefor safe, and secondly they are the movements that elicit a high neuroendocrine response Crossfit diet: protein 30%; carbohydrates 40%; fat 30% Protein: total calories based on protein needs which should be between 0.7 and 1.0 grams of protein per pound of lean body mass High glycemic carbohydrates: raise blood sugar too rapidly Ex: rice, bread, candy, potato, sweets, sodas Crossfits 10 general physical skills: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy Training refers to: activity that improves performance through a measurable organic change in the body Practice refers to: activity improves performance through changes in the nervous system: power and speed and adaptations of both training and practice Define accuracy the ability to control movement in a given direction or at a given intensity Define balance the ability to control placement of the bodys center of gravity in relation to its support base Define agility the ability to minimize transition time from one movement pattern to another Define coordination the ability to combine several distinct movement patterns into a singular distinct movement Define speed the ability to minimize the time cycle of a repeated movement Define power the ability of a muscular unit, or combo of muscle units, to apply maximum force in minimum time Phosphocreatine: short, anaerobic, max intensity, located in cytosol of muscle cells Ex: 100 m dash Glycolytic (lactate): medium, anaerobic, medium to high intensity, cytosol of all cells Ex: 400 m sprint Oxidative: long, aerobic, low intensity effort, mitochondria of cells Ex: anything greater than 120 seconds of sustained effort 4 fitness models of Crossfit: the 10 general physical skills, the Hopper, metabolic pathways, sickness-wellness- fitness continuum Tabata: interval training which is 20 seconds of work followed by 10 seconds of rest repeated 8 times; it increases aerobic and anaerobic capacity Define sport: the application of fitness in a fantastic atmosphere of competition and mastery
