The newest participants’ solutions had been measured on laboratory at rest, and you may submaximal including maximal performs pricing with the several other era, that have been finished within this on average six.0 ± eight.3 days. The players were unable to drink throughout the some of 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, 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 arrival at laboratory the participants was in fact considered and you can measured, and a check checklist is actually ticked over to determine whether they got followed the standard procedures called more than. The participants up coming rested quietly to own 10 minutes for the a drugs desk, and you may sleeping Hours, in this case calculated since that time months between every single Hour, is determined about average of your own five minutes between the 6 th and you will ten th moments.
Course ergometer do so protocol.
The players cycled during the around three more really works pricing: fifty, a hundred and you will 150 watt (W) on ladies, and you will one hundred, 150 and you will 200 W into boys. A great cadence out-of fifty innovations a minute (rpm) is actually chose (p. 19 from inside the ). At each functions rate the new member cycled up to constant-state (just as much as six times), then the brand new resistance is increased. The 3rd works rate try risen to merely 125 W otherwise 175 W for females and you may people correspondingly in the event that, pursuing the next work rates, the latest subject’s Hour are more than 150 beats a minute (bpm) and their recognized price out of effort (RPE) considering a beneficial Borg size exceeded fifteen both for foot and respiration (p. 30 during the ). The fresh new Time while the RPE were listed regarding process shortly after all second.
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 https://datingranking.net/pl/christian-cupid-recenzja/ 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.
