Exercise Physiology Field tests and easy functional trials Field tests Advantages - practical, inexpensive, less-time consuming, easy to administer to large groups (school) Disadvantages: - have been already discussed Based on: - walking, running, cycling, swimming, bench stepping, knee-bending - measurement of time, distance and mainly HR Heart rate - belongs to main cardiovascular fitness parameters - exercise causes increase, after exercise - decrease - HRrest – measurement in the morning after waking up before getting up HRrest × HRexercise × HRpostex. HRmax – generally decrease in trained or no change HRrest – 70 beats/min (average) ↑ 90 beats/min (tachycardia) ↓ 60 beats/min (bradycardia) Heart rate - Measurement - by tough of artery on wrist, neck, etc. (easy but inaccurate) - EKG very accurate but unpractical in sport - Monitor of heart rate – based on distance between R-R (chest belt – transmitter and watch - receiver ) Easy functional trails Monitoring of HR (rest, exercise, post-exercise) Problem: reliability (lots of different designs) There are many functional trails For example: a] Ruffier trial b] Step-test Ruffier test 1] monitoring of resting HR – real HRrest !!! [HR1] 2] 30 knee-bends in 30 seconds 3] sitting down and immediate monitoring of HR [HR2] 4] monitoring of HR 1 minute after exercise [HR3] Fitness index = (HR1+HR2+HR3) -200 10 Ruffier test Evaluation Index of fitness Level of fitness <0 excellent 0.1 – 5 good 5.1 – 10 average 10.1 – 15 under average > 15.1 poor Test is not suitable for elderly and persons with illnesses of lower limbs and joints. Step-test Based on decrease of pos-exercises HR Many of modification: Astrand-Ryhming step test protocol, Queen’s College step test protocol, Chester’s step test protocol We need: - bench (chair) - stop-watch - metronome (time keeper) - monitor of HR Chester’s step-test protocol 1] bench: 50 cm ♂, 40 ♀, 30 children 2] duration: 5 minutes if possible 3] frequency: 30 steps/min 4] movement: exchange of legs on the top of bench 5] immediate sitting down after termination of exercise 6] monitoring HR in recovery: - 1 min (HR1), 2 min (HR2), 3 min (HR3) after exercise Chester’s step-test protocol duration of exercise (s)*100 Fitness index = (HR1+HR2+HR3)*2 Evaluation Index of fitness Level of fitness < 90 poor 90 – 110 average > 110 good Field tests Walking test Based on achievement (duration) and reaction of HR We need: - stop-watch - monitor of HR - flat and direct path The task is: To walk as fast as possible 2 km long way, but NO RUN! (It should takes 12 – 16 min) Walking test Measurement: - duration in min (45 s = 0.75 min) - HR in finish (immediately) Calculation of: - age - BMI weight (kg) BMI (body mass index) = height2 (m) below weight = < 20 (♀ 19) normal = 20 – 25 (♀ 19 – 24) above weight = 25 – 30 (♀ 24 – 29) obesity = > 30 (♀ 29) Walking test (fitness index) male = 434-(duration-11.6)-(HR*0.56)-(BMI*2.6)+(age*0.2) female = 431-(duration-11.6)-(HR*0.56)-(BMI*2.6)+(age*0.2) Evaluation Index of fitness < 70 Level of fitness poor 71 - 89 under average 90 – 110 average 111 – 130 good > 131 excellent Walking test Estimation of VO2max VO2max = 132.85-(0.016*weight)-(0.39*age)+(6.32*G)-(3.26*duration)-(0,16*HR) kg years gender ♂=1 ♀=0 minutes The test is suitable for almost everyone, mainly for old persons. The test is not suitable for very well trained. Shuttle ran test (Leger’s test) Purpose: To estimate the maximum aerobic power. We need: - recorder with tape with pacing sounds on it - stop-watch - clear area with two parallel lines (20 m spacing) The task is: On the signal from tape to move from behind of one line behind the second line and back as long as possible Shuttle ran test (Leger’s test) Speed - start: 7.5 km/hour Increase of pace: 0.5 km/hour for one minute Termination: 1] feelings of inability to continue 2] inability to reach the line two times in sequence 20 m Shuttle ran test (Leger’s test) Evaluation: poor average good age < 5:30 > 7:30 10 < 7:30 > 9:00 14 < 8:30 > 10:30 20 < 7:00 > 8:00 30 < 5:00 > 7:30 40 problem: sliding – shoe sole Cooper test 12 minutes run test on 400-meter track The task is: To run as far as possible The test is based on positive correlation between the run distance and VO2max Estimation of VO2max VO2max = 22.36 * (km) – 11,29 Cooper test The test is suitable for healthy and better trained Highly dependent on motivation!!!
