Prevalence of sleep apnoea in patients with type 1 diabetes and its association with comorbidities and diabetic complications: A French nationwide prospective study.

Aim: To investigate sleep apnoea prevalence, factors influencing severity, and associations between sleep apnoea severity and micro-/macrovascular complications in a large population of patients with type 1 diabetes.

Materials And Methods: This French multicentre prospective cohort study was conducted between July 2016 and June 2020. Adults with type 1 diabetes using an insulin pump were eligible.

Effect of a protein-sparing diet on responses to exercise in obese subjects.

We have studied muscular work efficiency and VO2 peak in seven obese individuals (body mass index: 38.9 +/- 5.8 kg.

Postprandial thermogenesis and hormonal release in lean and obese subjects.

One group of 10 obese people (1.72 times normal weight) was compared to a control group of 9 normal-weight subjects. Oxygen consumption (VO2), immuno reactive growth hormone (IRGH), and rectal temperature (Tre) were measured every 15 min on an average, during the 5 h following a protein meal composed of 6 egg-whites and 50 g of casein totaling 1 340 kJ.

Determinants of increased energy cost of submaximal exercise in obese subjects.

The energy cost of submaximal cycling exercises is studied in 23 obese (OS) and 13 lean control (LS) subjects at 1) a constant pedaling frequency (60 rpm) and at various work loads [external work loads (Wmec) up to 100 W] for one group of OS and LS, and at 2) constant Wmec (brake free and 60 or 70 W) and various frequencies (38-70 rpm) for a second group of OS and LS. The total energy expenditure (WO2) is calculated from O2 consumption (VO2) measured in both conditions and is compared with anthropometric data. The results show that at rest or at the same Wmec, WO2 is always greater in OS than in LS.

Mechanics and energetics of stilt walking.

Three subjects were studied walking on a sports track with and without 1-m-long stilts. They were asked to walk in different ways. Pace length, step rate, heart rate, and oxygen consumption were measured under both conditions at different speeds.
