Excesso de exercício físico no início da gravidez pode aumentar risco de aborto

«PARIS (AFP) — As mulheres que praticam atividades esportivas intensas de mais de sete horas por semana no início da gravidez têm até 3,5 vezes mais chances de perder o bebê do que as que não fazem nenhum tipo de exercício físico, segundo um artigo da revista britânica New Scientist, da edição que chega às bancas no sábado.

As mulheres não devem, entretanto, deixar de praticar atividades físicas moderadas, como natação, diz o professor John Newnham, da University of Western Australia (Escócia) no mesmo artigo.

Os esportes mais arriscados são os chamados de "impacto", como corrida, esportes com bola ou raquetes, de acordo com a publicação, que cita um estudo dinamarquês com quase 93.000 gestantes.

A natação, em contrapartida, seria bastante benéfica, de acordo com o estudo.

Além disso, nenhuma relação foi encontrada entre o exercício físico e a perda do bebê após 18 semanas de gravidez.

Atualmente, os médicos da maioria dos países - incluindo Estados Unidos, Grã-Bretanha e Dinamarca - recomendam exercícios físicos na gravidez em níveis similares aos de mulheres que não estão grávidas.»

Yogi Ramacharaka of the Yogic Society of Chicago wrote some excellent books at the beginning of the 20th Century in which he said domesticated animals are at a higher spiritual level than many humans living in poverty If you must learn things because it is so difficult to remember in your physical state, perseverance, patience, and belief in yourself come in handy Tha hair should be cut with scissors and not shaved
