Vše o aerobicu

Základní pravidla

2. 2. 2009

Jedná se o ojedinělý vertikální trénink, kdy cvičenci vystupováním na step (stupínek o výšce zpravidla 10 - 30cm) a následným sestupováním z něj překonávají výškový rozdíl, čímž dochází k podstatně jinému zatěžování svalstva než u normálního aerobiku, zvláště pak svalstva dolních končetin.

Výzkumy prokazují, že ačkoliv je hudba na step aerobik poměrně pomalá, výdej energie se za určitou časovou jednotku vyrovná běhu.

V hodině je ovšem velmi důležité, aby docházelo ke stejnoměrnému zatěžování obou dolních končetin. K dalším důležitým pravidlům patří:

nikdy neseskakovat ze stepu dolu
nesestupovat zády k němu

Zajímavostí jistě je, že step aerobik se vyvinul z rehabilitačního cvičení pro pacienty po operaci kolenního kloubu. Při špatně prováděných pohybech v hodině však může paradoxně dojít k poškození právě kloubů kolen. Je nezbytně nutné, aby instruktor vedl hodinu odborně a vyvaroval se prvků možná líbivých, ale zdravotně závadných.

Velice důležitý je především strečink v závěrečné části hodiny, kde se nesmí zapomenou na nejvíce zatěžované svalové skupiny. Jedná se hlavně o lýtkové svaly, zadní stranu stehen a bedrokyčlostehenní sval.

Většina kroků ve step aerobiku je totožná s kroky ostatními. Jediný rozdíl je, že jsou prováděny vertikálně. Technika je také totožná – našlapovat přes patu, trup vzpřímený, nepropínat kolena.

The first successful birth of a child after IVF treatment, Louise Brown, occurred in 1978. Louise Brown was born as a result of natural cycle IVF where no stimulation was made. The procedure took place at Dr Kershaw's Cottage Hospital (now Dr Kershaw's Hospice) in Royton, Oldham, England. Robert G. Edwards was awarded the Nobel Prize in Physiology or Medicine in 2010, the physiologist who co-developed the treatment together with Patrick Steptoe and embryologist Jean Purdy; Steptoe and Purdy were not eligible for consideration as the Nobel Prize is not awarded posthumously.

The second successful birth of a test tube baby occurred in India just 67 days after Louise Brown was born. The girl, named Durga conceived in vitro using a method developed independently by Dr. Subhash Mukhopadhyay, a physician and researcher from Kolkata, India.

With egg donation and IVF, women who are past their reproductive years, have infertile male partners, have idiopathic female-fertility issues, or have reached menopause can still become pregnant. Adriana Iliescu held the record as the oldest woman to give birth using IVF and a donor egg, when she gave birth in 2004 at the age of 66, a record passed in 2006. After the IVF treatment some couples are able to get pregnant without any fertility treatments. In 2018 it was estimated that eight million children had been born worldwide using IVF and other assisted reproduction techniques.

Leftover embryos or eggs

There may be leftover embryos or eggs from IVF procedures if the woman for whom they were originally created has successfully carried one or more pregnancies to term. With the woman's or couple's permission, these may be donated to help other women or couples as a means of third party reproduction.

In embryo donation, these extra embryos are given to other couples or women for transfer with the goal of producing a successful pregnancy. The resulting child is considered the child of the woman who carries it and gives birth, and not the child of the donor, the same as occurs with egg donation or sperm donation.

Typically, genetic parents donate the eggs to a fertility clinic or where they are preserved by oocyte cryopreservation or embryo cryopreservation until a carrier is found for them. Typically the process of matching the embryo(s) with the prospective parents is conducted by the agency itself, at which time the clinic transfers ownership of the embryos to the prospective parents.<>6]

In the United States, women seeking to be an embryo recipient undergo infectious disease screening required by the U.S. Food and Drug Administration (FDA), and reproductive tests to determine the best placement location and cycle timing before the actual Embryo Transfer occurs. The amount of screening the embryo has already undergone is largely dependent on the genetic parents' own IVF clinic and process. The embryo recipient may elect to have her own embryologist conduct further testing.

Alternatives to donating unused embryos are destroying them (or having them implanted at a time where pregnancy is very unlikely), keeping them frozen indefinitely, or donating them for use in research (which results in their unviability). Individual moral views on disposing leftover embryos may depend on personal views on the beginning of human personhood and definition and/or value of potential future persons and on the value that is given to fundamental research questions. Some people believe donation of leftover embryos for research is a good alternative to discarding the embryos when patients receive proper, honest and clear information about the research project, the procedures and the scientific values.
