The brand new participants’ answers was in fact measured in the laboratory at rest, and you may submaximal along with maximal really works prices towards several additional period, which were accomplished in this on average 6.0 ± eight.three days. The participants were not able to drink while in the the screening.
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.
On the arrival during the lab the players had been considered and you can mentioned, and a check number is ticked off to determine whether they got observed the quality tips named a lot more than. The players upcoming rested quietly for ten minutes toward a medicines table, and resting Time, in this instance calculated ever since months anywhere between each and every Time, try computed throughout the average of your own 5 minutes between the 6 th and you will ten th minutes.
Years ergometer take action method.
The participants cycled within three different work pricing: 50, one hundred and you can 150 watt (W) into women, and you will a hundred, 150 and you may 2 hundred W towards the guys. A cadence from fifty designs per minute (rpm) are chosen (p. 19 in the ). At each works rate the fresh new fellow member cycled up to constant-condition (whenever six moments), after which the latest resistance try enhanced. The 3rd functions rate try increased to simply 125 W or 175 W for women and you will people respectively when the, following the next functions rate, the brand new subject’s Hours is higher than 150 sounds each and every minute (bpm) in addition to their detected rate out of exercise (RPE) based on good Borg size exceeded fifteen both for ft and you will respiration (p. 29 inside ). New Hours while the RPE had been listed on the protocol just after the 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 asiandating.
