Unformatted text preview: Kinesiology 352 Lab Kinesiology KIN 352 KIN Bioenergetics of Human Movement Lab TA: Brandt Pence [email protected] University of Illinois Exercise Immunology Research with Dr. Woods Research On a piece of paper, please include the following: -Name -Year -Concentration -Hobbies/Activities -What are your career plans? -What do you think will be your favorite topic? -What do you think will be your least favorite topic? On the Menu for Today: On Go over syllabus Understand the fundamentals of completing a good lab Understand write-up. write-up. List and explain fundamental statistical tests and List interpretations. interpretations. Briefly Introduce Topic for next lab *** We will try to get all lab materials posted on Dr. Woods’ *** netfiles by the end of the week netfiles *** In addition, I will post my powerpoints and lab guidelines *** on my netfiles account on https://netfiles.uiuc.edu/bpence2/shared Fundamentals of a good lab write-up: Fundamentals Make sure that you understand what the question is asking. Make Anytime you are asked to explain something physiologically, include not only what happened but also how it happened what how (always think about the mechanism of action). Double check all calculations Double Present facts, data, analyses and discussions (citing Present references for any discussion), not opinions or unsubstantiated generalizations. unsubstantiated Always consult your textbook for expected physiological Always results. Step back from your data and ask if the outcome makes sense. makes Fundamentals of a Good Lab (continued) Fundamentals Do not ramble to fill space. Be short and to the point Do with complete sentences and thoughts. with Be sure to reference and footnote all information and Be ideas which are not your own. This includes information gathered from your textbook. Two peerinformation reviewed articles are required for each lab report. If any question asks you to list examples, list a If minimum of two. minimum If asked to compare your data to norms, always list If your scores and the classification in which you fall (i.e. poor, good, average, etc.). poor, Citations Citations Each lab report requires at least two peer-reviewed Each two journal sources in addition to any other outside sources (textbook, internet sources, etc.) (textbook, Sources for journal articles: www.pubmed.com www.scholar.google.com Allows access to journal articles in electronic format http://search.grainger.uiuc.edu/linker/ UIUC Library Online It is also possible to access some articles directly It through Pubmed or Google Scholar through DO NOT cite Wikipedia (or similar open-sourced DO encyclopedias) encyclopedias) See the Format for Laboratory Assignments handout for See more information more Lab Quiz Lab To be given on the day of data collection Will contribute to total lab points (i.e. Will methods section) methods Will only cover methods One extra credit question will be One physiology-based (on selected quizzes) physiology-based Statistics Mean (M or X) is the arithmetic average and is calculated by summing all of the numbers within a data set and dividing the number by the number of data points within the data set. Data Set Mean Data 2 (2+4+6+8)/4 = 5 4 6 8 Pearson Product Moment Correlation (r) Pearson Is often used to express the degree of relationship Is between two variables (Note that many people simply refer to this association as the “correlation”). A correlation coefficient is a number ranging from –1.00 correlation to +1.00 which indicates the degree of relationship between two variables. The number denotes the strength of the relationship and The the sign indicates the direction of the relationship. the A positive number means that as one variable gets positive larger, the other variable gets larger. A negative number indicates that as one variable gets negative larger, the other variable gets smaller (or vice versa). To interpret the strength of the relationship To between physiological variables, it is common to use the following scale: 0.00 to 0.29 (low), 0.30 to 0.59 (moderate), 0.30 0.60 to 0.84 (moderately high) > 0.85 (high). 0.85 Lab 1 Introduction Lab Lab 1 (next week) will involve determining Lab Anaerobic Power from a series of tests Anaerobic Before coming to lab next week, read the Before Lab 1 instructions (there will be a quiz) Lab Come dressed for physical activity Shorts T-shirt NO open-toed shoes What is Power? What Work=Force*distance*cos(Angle) Power: Work/time, the work exerted over a Power: given time given Often we determine power by using the Often force necessary to overcome gravity (i.e. your body weight) multiplied by the vertical distance traveled distance Power = (positive work x 1.33)/t Work = force x distance Force = body Wt in N (FYI: 1 kg = 9.8N) 1 kg = 2.2 lbs Distance = ht of the step (0.45 m) x steps/min 1.33 constant t = 60 sec Next Week Next Prelab quiz over methods Lab 1, come dressed for physical activity Brief review lecture addressing lab report Brief requirements. requirements. ...
