How many calories are there in 1g of carbohydrate, protein, fat and alcohol?
1g carb = 4 calories 1g protein = 4 calories 1g fat = 9 calories 1g alcohol = 7 calories
What is the difference between a 1st, 2nd and 3rd class lever?
A first-class lever has the axis (fulcrum) located between the weight (resistance) and the force. Rare in human body. Ex. joint between the head and the first vertebra. The weight (resistance) is the head, the axis is the joint, and the muscular action (force) come from any of the posterior muscles attaching to the skull, such as the trapezius. In a second-class lever, the weight (resistance) is located between the axis (fulcrum) and the force. Ex. found in the lower leg when someone stands on tiptoes. The axis is formed by the metatarsophalangeal joints, the resistance is the weight of the body, and the force is applied to the calcaneus bone (heel) by the gastrocnemius and soleus muscles through the Achilles tendon. In a third-class lever, force is applied between the resistance (weight) and the axis (fulcrum). Ex. elbow joint. The joint is the axis (fulcrum). The resistance (weight) is the forearm, wrist, and hand. The force is the biceps muscle when the elbow is flexed.
What is the energy currency of the body, and what are the 3 pathways used to generate ATP?
ATP is the body's usable form of energy. The three pathways include phosphagen, glycolytic, and oxidative pathways. Phosphagen and glycolytic pathways are anerobic. In phosphagen, a phosphate is transferred to ADP to make ATP. Glycolysis breaks down glucose into pyruvate and ATP via chemical reactions. Oxidation (cellular respiration) is aerobic and occurs in the mitochondria. Involves krebs cycle and ETC.
Acute vs. chronic
Acute --> single bout of exercise Chronic--> regularly performed exercise
Define energy balance.
An athlete is considered to be in energy balance when the amount of energy or calories consumed through foods and beverages is equal to the amount of calories expended. Energy intake = energy expenditure
Aerobic vs. anaerobic
Anaerobic training (sprint) increases cell's ability to produce energy from the phosphagen and glycolytic pathways. Aerobic training (endurance) increases the ability to synthesize ATP via oxidation.
*Basic vs. applied research
Basic research attempts to answer a specific research question whereas applied research revolves around a specific question with the intention of applying the new info to solve a problem.
Define kinematics, kinetics and biomechanics.
Biomechanics studies the mechanical aspects of living organisms, including the internal and external forces on the body; Kinematics is what we can visually observe when watching a body in motion; refers to study of size, sequencing, and timing of movement, w/o reference to forces. Kinetics is the analysis of the actions of forces.
What is the difference between blocked and random practice?
Blocked practice is practicing one thing until you become proficient (aiming at one target) whereas random practice is practicing different things at one (aiming at different targets). Blocked yields better results during training sessions, but random yields better results during retention tests.
What are the structures used to form levers to allow movement of the human body?
Bones, ligaments, and muscles are the structures that form levers in the body to create human movement. In simple terms, a joint (where two or more bones join together) forms the axis (or fulcrum), and the muscles crossing the joint apply the force to move a weight or resistance. Levers are typically labeled as first class, second class, or third class. All three types are found in the body, but most levers in the human body are third class.
Impact of Dr. Cooper
Came up with aerobics. Studies conduction in The Cooper Institute in the 70's examined healthy benefits of jogging and popularized need for aerobic fitness.
How can exercise training impact the nervous system? (babe im probably going way too much into depth with these next few)
Can impact NS function with respect to both somatic and autonomic divisions. Strength training results in adaptations in skeletal muscles that assists NS muscle fiber activation. Endurance training reduces sympathetic activation b/c reduces stress.
Subdisciplines of exercise science
Categorized into 5 bases of knowledge: 1) physiological (exercise physiology; sport nutrition) 2) behavioral (exercise and sport psychology; motor behavior) 3) sports medicine (athletic training) 4) biomechanical (biomechanics) and 5) social science (sport sociology; sport history)
What is Title IX?
Education Amendment Acts of 1972; opened doorways of opportunity for women. Responsible for steady growth in the number of sports teams for girls and equal treatment; schools must demonstrate proportionality (opportunities are equal for boys and girls and are proportional to enrollment number), history of progress (continuing history of expanding women's rights), and accommodation of interest (everyone has accommodated the interests of women). States that "No person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any education program or activity receiving Federal financial assistance."
How can exercise training impact the endocrine system?
Endocrine: exercise activates pituitary gland to secrete growth hormones and antidiuretic hormone; exercise impacts hormones overall; endurance training reduces release of epinephrine and norepinephrine; insulin levels are higher during exercise; resistance training influences body's response to testosterone, insulin-like growth factor, and cortisol.
Define exercise science
Exercise --> participation in some quantified form of physical activity with intended purpose of improving health; exercise science --> study of how the human body responds to exercise or physical activity
How can exercise training impact the cardiovascular system? (Cardiovascular system consists of heart, blood vessels, and blood; principle function is to deliver oxygen and nutrients to tissues and carry away CO2)
Exercise affects each component of this system. Heart rate and stroke volume increase from rest to exercise. Exercise increases cardiac output. Output and heart rate are proportional to exercise intensity. This increases blood flow. The LT effects of exercising profoundly impact heart health. Heart gets bigger, stronger.
What impact does exercise have on human moods and emotions?
Exercise affects moods, feelings of depression, and levels of anxiety. Increasing evidence points to a positive association between mental health and exercise. Performance can be affected by motivation, confidence, mental imagery, and goal setting. Researchers used questionnaires to determine that acute exercise causes states of emotions that change quickly and range in intensities. Researchers found that chronic exercise involves traits, more stable psychological measures. Prolonged periods of training may be associated with negative mood changes.
How can exercise training impact the respiratory system? (Comprised of lungs and airways that conduct air flow; functions are ventilation, or drawing air in, and diffusion, or the process by which oxygen and CO2 are exchanged in blood)
Exercise induces changes in respiratory function to increase the delivery of oxygen to the lungs and the removal of CO2 from the body. Tidal volume and respiratory rate increase with exercise. Aerobic training increases maximal capacity of the lungs to breathe in air; Endurance training enhances rate of oxygen diffusion out of the lungs and into the blood
Define sport psychology.
Field encompasses wide variety of clinical, research, educational, and applied activities, focusing on the relationship of physical activity to mental well-being and various mental factors related to performance enhancement.

What is the difference between a macronutrient and a micronutrient?
Macronutrients vary in the way that they are digested, processed, and stored and in what ways they affect exercise and health. Three primary macronutrients include carbs, proteins, and fats. Micronutrients are substances the body requires in small amounts, including vitamins and minerals. Includes, for example, calcium, iron, and antioxidants.
What is the difference between massed and distributed practice?
Massed practice refers to practicing in one long time interval with short rest periods. Distributed practice refers to practice with long rest intervals during a session. General consensus is that distributed practice yields better results.
Define the law of practice.
Maximizing the number of practice trials; More practice leads to more learning; Change in performance is rapid at first then improves at a slower pace over time
Give a brief description of performance enhancement techniques: mental imagery, goal setting.
Mental imagery, or visualization, is a process of internalized mental rehearsal that involves multi-sensory representations of an athlete's competitive experiences. The goal is to reproduce athletic experience as closely as possible so that the person feels as if he is actually performing the sport. This technique appears to have a positive impact on motor skill learning. Goal setting refers to setting goals, which focuses an individual's attention on relevant cues and tasks needed for success. Outcome goals refer to the desired results of a competition. Performance goals indicate the athlete's desired standard. Process goals are concerned with how an athlete performs a skill or strategy.
Define motor behavior, motor control and motor learning.
Motor behavior refers to the study of human movement or action. It involves two overlapping themes: motor control and motor learning. Motor control focuses on the processes that underlie the production of movement in health and disease whereas motor learning focuses on how skilled movements are acquired, including the optimal conditions for learning new motor skills.
*Important discovery in early 20th century
Muscles are powered by carbs, not by heat; evidenced by buildup of lactic acid in fatigued muscles
What was the conclusion (major finding) of the study by Ciolac and Greve (2011)?
Overweight/obese women displayed impaired heart rate response to exercise. Both groups improved muscle strength, but only normal weight women improved CR fitness and HR response to exercise. These results suggest that exercise-induced improvements in CR fitness and HR response to exercise may be impaired in overweight/obese postmenopausal women.
*Antoine Lavoisier's discovery
Oxygen uptake increased with physical exertion
*Health promotion vs. sport performance
Physiological components of health include cardiorespiratory endurance, muscular strength and endurance, flexibility, and body composition. Physiologic variables related to sport performance include speed, strength, power, agility, and quickness.
Define exercise physiology
Physiology --> study of human function Exercise physiology --> study of how the body functions during physical exertion that is carefully quantified
*Fernand LaGrange
Published first textbook of exercise physiology (The Physiology of Bodily Exercise)
Define resting metabolic rate.
RMR is the number of calories expended to maintain the body's life-sustaining processes during 24 hours. BMR and REE (resting energy expenditure) are considered synonymous with RMR. It can be calculated by measurement of gas exchange using metabolic cart. RMR is affected by age, sex, muscle mass, health, hormones, etc.
What is meant by sociological imagination?

Exercise physiologist: analyzes patient's fitness to help them improve health; works with patients with diseases; boost athletes' performance; use evaluation tools to design a fitness program; Fitness instructor: teach exercise in a group setting; lead, instruct, and motivate individuals or groups in exercise activities
Give a brief description of techniques used to reduce pre-performance anxiety: relaxation, thought redirection
Relaxation techniques reduce emotional and physical sensations of stress, as well as stressful thoughts. If you can learn to relax your breathing and reduce your muscle tension, your mind will follow. Deep breathing and meditation are examples. Positive-Thought-Redirection is a great way of dealing with intrusive, negative thoughts. As negative thoughts pop up during your daily life, you issue a "stop" command which acts to stop the negative thought in its tracks. Once the unnecessary, negative or burdensome thought is stopped, you then redirect your mind to a more positive thought about the situation you are confronting.

The impact has been far and wide. It has influenced the following: equal access to higher education, career education, protection for pregnant and parenting students, equal access to academia, changing gender stereotypes, fighting sexual harassment, access to athletics, scholarships, increased self-confidence in girls.
What was the conclusion (major finding) of the study by Cowden (2016)?
The results found that EI was a predictor of MT and that the relationship bw EI and coping effectiveness was mediated by MT. Findings suggest that EI may be important mechanism through which mentally tough responses are generated. The attributes of MT account for superior coping effectiveness reported in athletes high in EI.
Give examples of non-traditional areas where sport psychology is utilized. (Idk I think this answer is right)
Topics in which sport psychology is used include coach-athlete relationships, eating disorders in athletes, psychological factors of injury and rehab, team cohesion, and attentional focus.
