The latest participants’ answers was mentioned regarding research at peace, and you will submaximal and additionally maximal performs prices into the a few some other occasions, that have been finished inside typically six.0 ± 7.three days. The participants were not able for throughout the all tests.
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.
Toward arrival at the lab the participants have been considered and measured, and a check record is ticked out over determine whether it had observed the standard actions called a lot more than. The participants upcoming rested quietly having ten full minutes for the a prescription dining table, and asleep Time, in this situation calculated from the time several months anywhere between every Time, are calculated on the average of one’s 5 minutes within 6 th and 10 th minutes.
Stage ergometer do so process.
The players cycled in the around three additional work pricing: 50, 100 and you will 150 watt (W) into women, and a hundred, 150 and you can 200 W with the people. A great cadence out-of fifty revolutions per minute (rpm) try chose (p. 19 inside ). At each really works speed the fresh fellow member cycled until regular-condition (around six minutes), and then the fresh resistance are increased. The third performs rates are risen to simply 125 W otherwise 175 W for ladies and you can boys correspondingly in the event the, following next really works speed, new subject’s Time is actually higher than 150 sounds each minute (bpm) in addition to their seen price from effort (RPE) considering good Borg measure surpassed 15 for both legs and you will breathing (p. 31 in the ). The Hours as well as the RPE have been listed waplog bezplatná zkuÅ¡ebnà verze on the protocol immediately after all the minute.
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.
