Nutrition is an important tool in the field of sports practice; once well oriented it may reduce fatigue, which allows the athlete to train longer or recover better between the training sessions. The aim of this study was to investigate the efficacy of a carbohydrate drink (Gatorade) on the recovery heart rate and blood lactate levels. 20 healthy men were recruited as subjects. Flavoured water or Gatorade was given randomly to the subjects 20 minutes prior to exercise. The subjects were made to exercise under Bruce treadmill protocol. The peak exercise heart rate and blood pressure were recorded, when the subjects underwent passive recovery in supine lying, and the recovery heart rate was recorded. The post exercise blood sample was analyzed for blood lactate and glucose concentrations. The same subject was followed up after 48 hours for the second trial. The findings of the study indicate statistically significant differences between Gatorade and Placebo drinks (p<0.05) in post exercise lactate (t=3.04) and glucose levels (t=3.52). Significant differences were also recorded in heart rates at the 3rd, 5th and 8th minutes of passive recovery with (F=4.47), (F=5.60) and (t=4.35) respectively. Gatorade increases performance by limiting lactate accumulation and improves cardiovascular responses by keeping a low heart rate thereby delaying the onset of fatigue. [ABSTRACT FROM AUTHOR]

Objective: To improve counseling on congenital lung malformations (CLM) by describing long-term outcomes of children either operated on or managed by observation., Study Design: We analyzed lung function (spirometry), exercise tolerance (Bruce treadmill), and physical growth of 8-year-old children with CLM who participated in our longitudinal prospective follow-up program. The data are shown as median standard deviation scores (SDS) with IQR, or estimated marginal means (95% CI) on the basis of general linear models., Results: Twenty-nine (48%) of the 61 children had required surgery at a median age of 108 (IQR: 8-828) days, and 32 (52%) were managed by observation. In the surgery group, all lung function measurements (except for forced vital capacity [FVC]) were significantly below 0 SDS, with median FEV 1 -1.07 (IQR: -1.70 to -0.56), FEV 1 /FVC -1.49 (-2.62 to -0.33), and FEF 25%-75% -1.95 (-2.57 to -0.63) (all P < 0.001). Children in the observation group had normal FEV 1 and FVC, whereas FEV 1 /FVC (-0.8 1 (-1.65 to -0.14)) and FEF 25%-75% (-1.14 (-1.71 to -0.22)) were significantly below 0 SDS (both P < 0.001). Mean exercise tolerance was significantly below 0 SDS in both groups (observation: -0.85 (95% CI: -1.30 to -0.41); surgery: -1.25 (-1.69 to -0.80)); eight (28%) children in the observation group and ten (40%) in the surgery group scored <-1 SDS. Physical growth was normal in both groups., Conclusion: Children with CLM may be at risk for reduced lung function and exercise tolerance, especially those who required surgery. As little pulmonary morbidity was found in children with asymptomatic CLM, this study supports a watchful waiting approach in this group., (© 2019 The Authors.
