Laboratory assessment, standardization measures and you may rest requirements.

The brand new participants’ responses was indeed counted in the laboratory at rest, and you will submaximal in addition to maximal works costs with the several additional days, which were completed within an average of six.0 ± seven.three days. The participants were not able for while in the the examination.

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 coming in the lab the participants have been weighed and you can mentioned, and you may a record is ticked off to determine whether they got adopted the standard measures titled significantly more than. The participants next rested privately having ten full minutes into the a medicine table, and you will asleep Time, in this case calculated since period anywhere between each Hr, are determined about average of your own five full minutes involving the 6 th and you can 10 th moments.

Cycle ergometer get it done process.

The players cycled in the about three other works pricing: 50, one hundred and 150 watt (W) into the women, and you can one hundred, 150 and you can 2 hundred W into men. A cadence from 50 innovations a minute (rpm) was chose (p. 19 inside ). At each works price the brand new new member cycled until constant-state (around six minutes), after which new opposition was enhanced. The 3rd work price try risen to simply 125 W otherwise 175 W for ladies and you may boys correspondingly in the event the, following second work rates, the new subject’s Hours is higher than 150 sounds a minute (bpm) as well as their identified rates regarding exercise (RPE) based on an effective Borg measure surpassed 15 for both legs and you may breathing (p. 29 during the ). The Hours while the RPE had been indexed from the protocol just after every moment.

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 quizy chathour 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.
