1.21.14 kin 470 exercise physiology class notes- Grad TA’so Thomas & Beno Lab = 30% grade- Professor Deboldo Expertise: muscle biophysics- Exercise physiologyo Studying how physiology responds to exercise Short term- When you start exercising running around- Heart, breathing, blood, hormones- Acute changes Chronic effects- Heart hypertrophy- Long termo Power output Olympics! Walking ~50 Watts Sprinting > 2000 Watts How are muscles able to do that?o Cardiac output: endurance sports Rest 5 L/min Max exercise 35 L/min! We will see profound changes in amount of blood pumped through heart- Impact on sports performanceo Skates Used to be static, attached at both toe & heel Scientists realized you can flex bottom of foot Eliminating muscle groupo Clapskate Skate articulates, comes off boot, can flex gastroc Records broken quickly afterward Challenging to skate on- What do performance enhancing drugs do?o Why choose to use these?o What do the drugs do?o Taking advantage of things we’ve learned in exercise physiology… tweaking things that will amplify thato Lance Armstrongo Many cross country skiers have used performance enhancing drugso Blood dopingo EPOo Why so advantageous? What does it give them?- Questions we will addresso How are the physiological systems able to meet the demands of exercise? Heart Muscles- Energy used?- 50500 watts lungs- breathing changes- increases…- stimulated? Controlled?o What signals drive these changes Hormoneso How does the body adapt to chronic exercise? How does it help you?o Is fatigue all in your head?- Course objectiveso See syllabus- Formato Lectureso Small group problem based learning exercises In class, for credito Online homework assignments moodleo Laboratory exercises (start next week) VO2 max test Wind gate test – anaerobic power- Texto Powers and howley, Exercise physiology: theory and application to fitness and performance (6th, 7th, or 8th)o Materials for lecture and lab posted on moodle- Office hourso 158 totmano tues/thurs 11:15-12:05o [email protected] grad TA Thomas [email protected] Totman 21 Ben [email protected] Totman 22o Undergrad Matthew Unger- Evaluation of gradingo 3 exams 2 midterms (20%) & final (25%) 1 final- cumulative section (15% final section, 5% cumulative)o assignments & class work 5%o lab = 30%- course outlineo ch. 2, 3, 4 – exam 1o ch. 9, 10 – exam 2o ch. 8, 12, 13 – final- tips for success:o overcome the curveo study in little chunks of time immediately after class boost knowledge- shift curve to remember longer spend more time looking at material in several small chunks, helps retaino 1. Read section before class night before (day or two before)o 2. Clarify musunderstanding with prof and TA’s asapo 3. Prepare for exams by making and answering questions on the material- next time: start chapter 2, exercise &
