Effect of Weight Loss on Aerobic Capacity in Patients with Severe Obesity Before and After Bariatric Surgery

Severe obesity has been associated with adverse effects on physical capacity. In a prospective study, the aerobic capacity of severely obese patients was measured in order to observe the physiological response to weight loss from bariatric surgery. Sixty-five consecutive patients (40.4 +/- 8.4 years old; 93.8% female; body mass index = 49.4 +/- 5.4 kg/m(2)) were evaluated before bariatric surgery and then 6 and 12 months after surgery. Aerobic capacity was assessed with a scientific treadmill to measure maximal oxygen consumption (VO(2max)), heart rate, blood pressure, time on the treadmill, and distance walked (modified Bruce test). For the three observational periods, VO(2max) was 25.4 +/- 9.3, 29.8 +/- 8.1, and 36.7 +/- 8.3 ml/kg/min; time on the treadmill was 5.4 +/- 1.4, 6.4 +/- 1.6, and 8.8 +/- 1.0 min; and distance walked was 401.8 +/- 139.1, 513.4 +/- 159.9, and 690.5 +/- 76.2 m. For these variables, significant results (p = 0.0000) were observed for the two postoperative periods in relation to the preoperative period. Severely obese individuals increased their aerobic capacity after successful bariatric surgery. The data also suggests that a positive and progressive relationship between weight loss and improvement in fitness as a moderate loss of weight 6 months after surgery already showed some benefit and an additional reduction in weight was associated with a better performance in the aerobic capacity tests at the 12-month follow-up.FAPESP Fundacao de Amparo a Pesquisa do Estado de Sao Paul

Journée sans culture : Troubler la fête, rallumer notre joie = To Spoil the Party, To Set Our Joy Ablaze

"Composed as an extension of the conversations that took place during the 2015 Journée sans culture, To Spoil the Party, to Set Our Joy Ablaze gathers contributions from those who moderated the discussions of the day as well as those who set up its sites of rest, reflection, and play. These authors work to remain true to the spirit of what they lived, led by the desire to find a source of collective energy that exceeds the pervasive effects of tiredness and resignation. Their texts are joined by others, commissioned by the editorial team, which explore matters of concern not sufficiently addressed during the day." -- Publisher's website
