A test of aerobic capacity: description and reliability.

The purposes of this study were 1) to describe a maximal aerobic capacity (MAC) test and 2) to report on its reliability. Thirty subjects (16 males and 14 females) were tested for maximal aerobic power (MAP) with a progressive bicycle ergometer test and the ventilatory anaerobic threshold (VANT) was determined. MAC was measured as the amount of work that could be performed in 90 min on a bicycle ergometer at an intensity set individually from VANT. Subjects were asked to perform as much work as possible during this non-stop 90 min period. For females and males respectively, MAP reached 42.9 +/- 5.9 (mean +/- SD) and 56.0 +/- 4.7 ml O2/kg X min-1 (p less than .01), VANT 36.3 +/- 6.1 and 46.0 +/- 5.2 ml O2/kg X min-1 (p less than .01), max HR 198 +/- 8 and 195 +/- 9 (p greater than .05) and HR at VANT 187 +/- 9 and 180 +/- 10 (p greater than .05). The same subjects were tested twice for MAC within 7 days. Results expressed in kJ/kg reached 10.6 +/- 2.1 and 10.8 +/- 2.4 for females, 14.7 +/- 2.1 and 14.9 +/- 2.2 for males. Mean HR maintained during MAC were 174 +/- 11 and 174 +/- 9 for females and 169 +/- 10 and 170 +/- 10 for males. There was a non significant difference between means (p greater than .05) of the first and second test in total work performed in kJ/kg. This difference reached about 2% of the first test score, 32.7% of this difference occurring in the first 10 min.(ABSTRACT TRUNCATED AT 250 WORDS)

Tests of anaerobic alactacid and lactacid capacities: description and reliability.

The purpose of this paper is 1) to describe maximal anaerobic alactacid (AAC) and lactacid (ALC) capacity test and 2) to determine their reliabilities in men and women. The subjects were submitted to either a 10-s (2 trials) or a 90-s (1 trial) all-out ergocycle test for AAC and ALC respectively. Thirty-four male and 24 female subjects were tested for AAC, while 21 males and 19 females took part in the ALC test. A modified bicycle ergometer allowed the exact measurement of the distance and the work load for the computation of the work performed. load for the computation of the work performed. Each subject was tested and retested within 7 days. In both AAC and ALC, male subjects performed more work than women. AAC was 108 +/- 16 (mean +/- SD) and 90 +/- 14 J/kg for males and females respectively while ALC was 486 +/- 50 and 377 +/- 34 J/kg. Although the work load was designed to be 0.09 kp/kg for the AAC and 0.05 kp/kg for the ALC tests, there were wide variations between subjects with respect to the optimal load (AAC: from 0.05 to 0.11; ALC: from 0.03 to 0.06 kp/kg). Reproducibility was consistently high, with intraclass correlations of 0.98 and 0.99 for AAC (AAC-Max) and ALC respectively, with no difference between the male and female subgroups. It is concluded that these AAC and ALC tests, designed under assumptions of face validity, allow for differences between males and females and are highly repeatable.

Submaximal power output in adopted and biological siblings.

Submaximal power output was determined in relative steady state on a bicycle ergometer at a heart rate of 150 beats per minute (PWC150). PWC150 was measured in 880 individuals, 9 to 26 years of age, belonging to 46 sibships of adopted sibs, 66 sibships of unrelated individuals including adoptees, 33 sibships of first-degree cousins, 225 sibships of biological sibs, 56 sibships of DZ twins and 54 sibships of MZ twins. PWC150, PWC150/kg of body weight, PWC150/kg lean body mass, PWC150/cm of height and PWC150/m2 of body surface area were submitted to analysis of variance and correlation analysis after statistical control over age and sex of subjects. Few significant resemblances were found in PWC measurements for adoptive siblings, unrelated sibs and cousins. Sibling resemblance was, however, significant for the sibships of biological sibs, and of DZ and MZ twins. Interclass correlations reached significance only in pairs of biological brothers and sisters, and in pairs of DZ and MZ twins. Estimates of total genetic effect in PWC150/kg in a population of free-living children, adolescents and young adults vary from 0.30 to 0.48. It is concluded that submaximal power output is only moderately affected by the genotype.
