Maximal exercise tolerance tests were given to 30 female subjects 17-22 years old. The test consisted of exercising 1 min at a work load of 300 kpm/min and increasing the work load 150 kpm/min each minute until the subject could no longer exercise. The maximal heart rate level averaged 184 beat/min with a range between 170 and 202 beat/min. The average maximal Vo2 was 1.78 liter/min or 29.8 ml/kg per min. The submaximal ventilatory measurements were similar for all subjects while the heart rate levels at the submaximal work loads differentiated the subjects when grouped according to maximal work-load capacities. Prediction of maximal work capacity could not be made for individuals from any single submaximal measurement. There was .56 correlation between body weight and maximal work capacity with only a .32 relationship between maximal Vo2 and Vo2 per kilogram body weight. exercise tolerance of women; cardiorespiratory function of women during exercise; submaximal cardiorespiratory response; maximal cardiorespiratory measurements of women; response to maximal exercise; prediction of exercise tolerance Submitted on May 5, 1964

The Relationship

The relationship between physical activity measured using the LSI (Large Scale Integrated Activity Monitor), and questionnaire, with physical work capacity 170 (PWC 170) and aerobic capacity (peak V̇O2) was evaluated in 6- to 8-year-old children (n = 18). The mean (± SD) peak V̇O2 was 44.1 ± 5.6 ml • kg−1 • min−1. Peak V̇O2 was not significantly different for children (n = 8) who had completed two treadmill trials (45.4 vs. 43.5 ml • kg−1 • min−1; R = 0.67, p<0.05). The log LSI expressed as counts per hour (M ± SD = 2.1 ±.22 cts/hr) was the only activity method significantly related to peak V̇O2 (r = 0.59, p<0.05). The correlation between peak V̇O2 with the questionnaire was positive but nonsignificant (r = 0.20). PWC 170 was not related to peak V̇O2 (r = 0.21) or the activity variables (r = 0.12 questionnaire; r = 0.18 log LSI). When the group was divided into high and low peak V̇O2 groups (high: M = 48.8 ml • kg−1 • min−1; low: M = 39.5 ml • kg−1 • min−1), the log LSI was able to distinguish significant differences in activity levels (high: 2.23 ±. 19 cts/hr; low: 1.99±.19 cts/hr). This study suggests that activity measured with the LSI and aerobic capacity are related in this sample of 6- to 8-year-old children.

The Relationship

Background: The influence of sleep related breathing disorders on heart rate variability (HRV), a measure of autonomic nervous function, is not well studied. We therefore assessed the relationship of the Apnea-Hypopnea Index (AHI) and the Oxygen Desaturation Index (ODI) with 24-hour HRV in a large population of young and healthy adults. Methods: Individuals aged between 25-41 years with a body mass index ≤35km/kg2 and without known sleep apnea syndrome (SAS) or cardiovascular disease were included in the population-based GAPP-study. A 24-hour electrocardiogram (ECG) was obtained in every participant, and systematic post-processing performed with a dedicated software. The standard deviation of all normal RR intervals (SDNN) was used as main HRV marker. AHI and ODI were obtained from nighttime pulsoxymetry with nasal airflow measurements. Sleep apnea (SA) was defined as either an AHI ≥5 or an ODI ≥5. Multivariable regression models were constructed to assess the relationship of SDNN with either AHI or ODI and to adjust for a large number of confounders. Results: We included 1266 participants (47% men) with a median age of 35 years. Mean SDNN among men and women was 162 and 148ms (p<0.0001), respectively. The proportion of participants with SA using an AHI- or ODI-based definition was 10 and 11%, respectively. Compared to individuals without SA, the beta coefficient (95% confidence interval (CI)) for SDNN was -7.48 (-14.75; -0.23, p=0.04) among those with an AHI-based SA definition, and was -11.45 (-18.39; -4.52, p=0.001) among those with an ODI-based SA definition. A highly significant inverse trend across different categories of AHI and ODI was observed, as shown in the Table. Conclusion: Early stages of sleep related breathing disorders are strongly associated with decreasing HRV in young and healthy adults, without evidence of a threshold. These findings suggest a tight link between sleep related breathing disorders and autonomic dysfunction.
