Exercise Physiology Field tests and easy functional trials

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 !!! [HR 1] 2] 30 knee-bends in 30 seconds 3] sitting down and immediate monitoring of HR [HR 2] 4] monitoring of HR 1 minute after exercise [HR 3] Fitness index = (HR 1+HR 2+HR 3) -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 (HR 1), 2 min (HR 2), 3 min (HR 3) after exercise

Chester’s step-test protocol duration of exercise (s)*100 Fitness index = (HR 1+HR 2+HR 3)*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 (body mass index) = weight (kg) height 2 (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 VO 2 max = 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 VO 2 max Estimation of VO 2 max = 22. 36 * (km) – 11, 29

Cooper test The test is suitable for healthy and better trained Highly dependent on motivation!!!
