1 Measuring in Competitive Sports and Coaching Chapter 12Measuring in Competitive Sports and Coaching
2 Impact of Measurement on Sports Equipment requirements for different groups increase a sport’s expense.Rule changes make recordkeeping difficult.Logistics can be complicated if different equipment has to be available and moved into place as needed.
3 Measurement Challenges in Competitive Sport Training for officiating:How can we make sure that judges and officials are valid, reliable, and objective?Discarding scores (highest and lowest)Rules and rule changesChanges to the structure of competitions and to athletes
4 Your ViewpointWhat are examples of measurement issues that you’ve observed in sporting events? Did these issues affect the outcome of a game or event?What solutions would you recommend to address these issues?
5 Measuring in Coaching, Teaching, and Training Coach: Select the best team possible, adjust strategy for maximum benefit, and teach others to enjoy the game (regardless of outcome).Teacher: Assess and motivate students.Trainers and therapists: Evaluate injuries and capabilities, give athletes exercise prescriptions and motivate them to complete rehab programs, evaluate efficacy of a treatment.
6 Coaches and Measurement Formative and summative evaluations:Formative: Measure and evaluate players during practice and during games.Summative: Pick the starting team and select award recipients.Quantitative and qualitative measures:Quantitative: Scoring, general performance, skill abilityQualitative: Coachability, leadership, and determination
7 Measuring Recruits— Professional Sport Spend time and effort examining every aspect of a potential investmentConduct various tests:Combine: Tryout to determine which prospects to draftPost-combine performance testingTests of specific skills
8 NFL Drafting Test 50-item Wonderlic intelligence test Height and weight measurements225-lb. bench pressStanding broad jump40-yard dashShuttle runVertical jump
9 Measuring Recruits— College Sport Analyze films and reports from high school coachesTest students at football summer campConsider factors not related to athletic performance:AcademicsAttitudeCooperation/coachability

11 Your ViewpointPretend you are a college coach recruiting for a particular sport. What key qualities do you want to see in the athletes you are recruiting?How would you measure or evaluate those qualities in your recruits?
12 Measuring in Athletic Training Modern medical measurements:Previously, only X-raysNow, new equipment (CT scans, MRIs), faster laboratory results, and an abundance of dataTechnology offers new treatment modalities(continued)
13 Measuring in Athletic Training (continued) Using standard scores:Comparison to a norm (e.g., other athletes) or to some criterion (e.g., an uninvolved body part)Assessing hydration status:Challenge to trainersA rapid change in body weight—only practical method for measuringAssessing potential for heat injuries
14 Assessing Potential for Heat Injuries Dry bulb temperatureWet bulb temperatureGlobe temperatureWet bulb globe temperature (WBGT):Weighted average of the other temperatures
15 Calculating WBGTWGBT = 0.7 * wet bulb temperature * dry bulb temperature * globe temperatureIf a wet bulb reading is 30º C, dry bulb is 35º C, and globe reading is 38º C:(30 * 0.7) + (35 * 0.2) + (38 * 0.1) == 31.8º C
17 Significance of Three Weighted Measurements “Hotness” of a day:Combination of air temperature, humidity, and windWBGT reflects all three factorsWet bulb temperature (body’s heat loss through sweat evaporation) is most important; makes up 70% of WBGT.
19 WBGT and Various Athletes Football players:Need to make an adjustment to the measured WBGT to account for heavy clothing and equipment.Young athletes:Be alert for heat-related symptoms, offer rest periods and plenty of fluids.WGBT at or above 85º F or 29.4 º C: All outdoor athletic activities should be prohibited.
20 Measuring in Hunting and Fishing Measure weight or lengthBig game animals:Measure body weight and points
21 Measuring Multisport Competitions Biathlons and triathlonsPerhaps the greatest measurement challenge in sports:Course set-ups affect which group of athletes will be favored; e.g., longer swim vs. longer run portionComparison of times difficult among events on different courses

24 Illicit Substances Used by Athletes and Employees NCAA’s list of banned drugs:Substances commonly tested for in employment drug tests:AlcoholMarijuanaCocaineAmphetaminesOpiatesPCPGHB
25 Possible Outcomes of Drug Tests Valid and desirable:True positiveTrue negativeNot desirable:False positiveFalse negativeSensitivity: Probability of a positive test among people with a condition.Specificity: Probability of a negative test among those who do not have the condition.
