A couple trained detectives carried out the newest research assessment, for every participant getting the same detective for every single take to
The fresh new participants’ answers was basically counted about laboratory at rest, and submaximal and additionally maximal really works pricing towards the a couple of some other hours, that have been complete within this typically six.0 ± seven.three days. The players were unable for while in the the evaluation.
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 in the laboratory the participants was basically weighed and you will measured, and you will a check number is actually ticked out over determine whether it had accompanied the standard measures entitled significantly more than. The participants next rested on the side for ten minutes towards the a treatment dining table, and you can resting Time, in this case calculated since that time several months anywhere between each and every Time, was computed about average of five minutes involving the six th and you can 10 th times.
Period ergometer do it process.
The players cycled at around three additional functions costs: fifty, 100 and 150 watt (W) on women, and you will a hundred, 150 and you can 200 W on the people. A beneficial cadence away from fifty designs a minute (rpm) is picked (p. 19 inside the ). At every performs price the participant cycled up until steady-county (around six times), then the fresh resistance is increased. The third really works rate try risen to merely 125 W or 175 W for women and men respectively when the, pursuing the 2nd functions price, the fresh new subject’s Time try higher than 150 sounds for each minute (bpm) in addition to their observed speed off effort (RPE) considering a beneficial Borg level surpassed 15 for legs and you may breathing (p. 31 for the ). Brand new Hours as well as the RPE have been noted from the method once all 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 bronymate 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.
