Estudio preliminar de la ingesta de nutrientes de niños deportistas de Sierra Nevada

A study was conducted of the diet of a child Alpine ski competition team (Monachil Club, Sierra Nevada). The children,aged between 7-12 years old, were divided into two groups. One of which were residents at a ski resort and the other,residents from different cities, who practised skiing at the same resort at weekends only.A 24-hour recall questionnaire was carried out, from which the following data was collected: The mean energy valuefrom diet intake was determined at 3,218 ± 819 Kcal/day (ski resort group) and 2,485 ± 600 Kcal/day (city group). Nosignificant differences between the groups was observed (p≥0.3). The distribution of energy from energetic nutrients wascorrect for the ski resort group, both at the weekend and during the week; the city group had an excessive intake oflipids (43%) and proteins (17%), and the energy from carbohydrates did not reach 55%. A modification in the diet andintake of energy and nutrients was observed when the children moved from their family home to the ski resortSe ha realizado un estudio de la dieta del equipo de competición infantil en esquí alpino (Club Monachil, SierraNevada).

Ladistribución de energía a partir de los nutrientes energéticos es correcta para los niños deportistas de la sierra, tantoen el fin de semana como entre semana; los niños deportistas de ciudad tienen un consumo excesivo de lípidos (43%)y prótidos (17%), el aporte de energía de carbohidratos no llega al 55%.

Yoga Enhances Positive Psychological States in Young Adult Musicians

Although yoga has been shown to be a viable technique for improving the performance of the mind and body, little attention has been directed to studying the relationship between yoga and the psychological states of flow and mindfulness. Musicians enrolled in a 2-month fellowship program in 2005, 2006 and 2007 were invited to participate in a yoga and meditation program. Fellows not participating in the yoga program were recruited separately as controls. All participants completed baseline and end-program questionnaires evaluating dispositional flow, mindfulness, confusion, and music performance anxiety. Compared to controls, yoga participants reported significant decreases in confusion and increases in dispositional flow. Yoga participants in the 2006 sample also reported significant increases in the mindfulness subscale of awareness. Correlational analyses revealed that increases in participants' dispositional flow and mindfulness scores were associated with decreases in confusion and music performance anxiety. This study demonstrates the commonalities between positive psychology and yoga, both of which are focused on enhancing human performance and promoting beneficial psychological states. The results suggest that yoga and meditation may enhance the states of flow and mindful awareness, and reduce confusion
