Research examination, standardization strategies and you may other individuals requirements.
The new participants’ answers was in fact mentioned regarding lab at rest, and you can submaximal together with maximal performs costs into the a couple of different circumstances, that have been finished in this an average of 6.0 ± seven.three days. The participants were unable to drink throughout the assessment.
The participants were asked to follow the same standard procedures before each test occasion. These were: 1) not to engage in any vigorous exercise for 24 hours beforehand, 2) not to cycle to the laboratory https://www.datingranking.net/pl/connecting-singles-recenzja, 3) to refrain from eating, drinking, smoking and taking snuff (smokeless tobacco) for at least one hour before arrival at the laboratory, 4) not to eat a large meal at least three hours before the tests, 5) to avoid stress and 6) to cancel the test if they had fever, an infection or a cold. The time of day that the tests were undertaken was not standardised since it does not affect the HR-VO2 relation during physical activity . The participants wore light clothes, such as T-shirts, shorts and training shoes, so as to diminish any effect of the energy liberation from the submaximal exercises on sweating and body temperature.
Into the coming in the research the participants have been considered and you can measured, and you can a check list was ticked out to see whether it got implemented the standard measures called significantly more than. The participants upcoming rested on the side to have ten full minutes toward a medicine table, and you can sleep Time, in cases like this calculated since several months between each Hour, is determined throughout the average of your own five full minutes between your 6 th and 10 th minutes.
Period ergometer get it done process.
The players cycled during the three some other performs cost: 50, a hundred and 150 watt (W) on the people, and one hundred, 150 and you may 2 hundred W for the males. A good cadence of fifty designs a minute (rpm) is selected (p. 19 when you look at the ). At each and every performs price the new participant cycled up to steady-state (just as much as 6 times), and the brand new resistance is actually improved. The third performs price are risen up to simply 125 W otherwise 175 W for women and you may men correspondingly when the, following the 2nd work rates, this new subject’s Hours is actually higher than 150 beats a minute (bpm) and their imagined speed out-of effort (RPE) according to an excellent Borg size surpassed 15 for both feet and you may breathing (p. 29 into the ). The new Time in addition to RPE was detailed regarding the process once every time.
Between the second and third work rates the test person continued cycling for 1 minute at a self-chosen low cadence with a resistance of 5 N. The subject was then instructed to resume the cadence of 50 rpm while the investigator slowly increased the work rate until, after one minute, the third work rate was reached. For that purpose, resistance was increased to 50 W during the first 15 seconds, to 100 W the second 15 seconds and successively to the required work rate during the last 30 seconds). Also, after the third submaximal test, the subject continued cycling for two minutes at a self-chosen low cadence at 5 N. For the submaximal tests in the laboratory, the mean of the four 15 s values for VO2 and HR for the last minute of each work rate were used for analysis.
During the maximal exercise phase, the subjects cycled at a cadence of 80 rpm . For the first three minutes, the work rates were 60, 100, and 120 or 140 W for one minute each. The latter alternatives depended on which third work rate the subjects had during the submaximal work: 120 W if the third submaximal work rate had been 125 W or 175 W for women and men respectively; 140 W if it had been 150 W or 200 W for women and men, respectively. The work rate then increased by 20 W every 60 seconds. The test continued until exhaustion. HR was calculated for the whole minute before each increase of the resistance. The values for the maximal tests were calculated by averaging the highest four 15 s consecutive values for VO2 and HR at maximal exercise i.e. a collection period of 60 s . The same corresponding values were used for both VO2 and HR.
