ON MANAGEMENT STRATEGIES TO PREVENT CHILDHOOD OBESITY AND OFFSET FROM THE EDUCATIONAL FIELD

Currently, childhood obesity is one of the most important problems in the world health since in recent years has increased significantly in developed countries. The origin of this problem is due to a lifestyle based on little or no physical activity, coupled with poor and unbalanced diet. This condition, in turn, may adversely affect the formation of students due to low self esteem, depression and other psychological problems. The measures proposed are constant to the families of the students and the students themselves, through weekly lectures and workshops, which will take place in the school itself up. In addition, another measure would be to increase the number of hours of physical activity within the school timetable, taking advantage schedules for recreation and dining.The objective of the above work is to make a proposal, as a tool to prevent and treat overweight and obesity among children from the same education.The hypothesis of the project is that the BMI of the sample of the selected school will be reduced significantly due to changes in habits, promoted from this initiative, thereby improving their school performance. No conclusive results because it has not been implemented so far. </p

Similar Hemoglobin Mass Response in Hypobaric and Normobaric Hypoxia in Athletes

PURPOSE: To compare hemoglobin mass (Hbmass) changes during an 18-d live high-train low (LHTL) altitude training camp in normobaric hypoxia (NH) and hypobaric hypoxia (HH). METHODS: Twenty-eight well-trained male triathletes were split into three groups (NH: n = 10, HH: n = 11, control [CON]: n = 7) and participated in an 18-d LHTL camp. NH and HH slept at 2250 m, whereas CON slept, and all groups trained at altitudes &lt;1200 m. Hbmass was measured in duplicate with the optimized carbon monoxide rebreathing method before (pre-), immediately after (post-) (hypoxic dose: 316 vs 238 h for HH and NH), and at day 13 in HH (230 h, hypoxic dose matched to 18-d NH). Running (3-km run) and cycling (incremental cycling test) performances were measured pre and post. RESULTS: Hbmass increased similar in HH (+4.4%, P &lt; 0.001 at day 13; +4.5%, P &lt; 0.001 at day 18) and NH (+4.1%, P &lt; 0.001) compared with CON (+1.9%, P = 0.08). There was a wide variability in individual Hbmass responses in HH (-0.1% to +10.6%) and NH (-1.4% to +7.7%). Postrunning time decreased in HH (-3.9%, P &lt; 0.001), NH (-3.3%, P &lt; 0.001), and CON (-2.1%, P = 0.03), whereas cycling performance changed nonsignificantly in HH and NH (+2.4%, P &gt; 0.08) and remained unchanged in CON (+0.2%, P = 0.89). CONCLUSION: HH and NH evoked similar Hbmass increases for the same hypoxic dose and after 18-d LHTL. The wide variability in individual Hbmass responses in HH and NH emphasizes the importance of individual Hbmass evaluation of altitude training
