But in terms of hitters purposely revamping their swings to become extreme flyball hitters, this modern trend is often traced to Marlon Byrd, the outfielder serving a 162-game suspension after a second positive test for performance-enhancing drugs. In 2012, Byrd averaged two grounders for every flyball, a rate that was in line with his career numbers to that point. But in 2013, after working with an obscure, independent swing instructor named Doug Latta who runs a baseball training facility in Chatsworth, Calif., Byrd cut that rate in half and produced the best season of his career.
The chance of a reaction to the contrast material is a very small, but potentially significant risk. It is estimated that only 5–10% of patients experience any effect from contrast exposure. The vast majority of reactions are mild, such as sneezing, nausea, or anxiety. These usually resolve by themselves. A moderate reaction, like wheezing or hives, may be treated with medication, but is not considered life threatening. Severe reactions, such as heart or respiratory failure, occur very infrequently, and require emergency medical treatment.
The woman who has learned to record and interpret the changes in her Temperature Chart during her cycle, can recognise from the Temperature pattern whether or not she is ovulating. This knowledge is reassuring to the couple who wish to achieve pregnancy but as the ovum lives for just 24 hours the thermal shift is of little use in planning pregnancy; the mucus symptom before ovulation is the indicator of choice for the woman who wishes to conceive. The temperature chart will also confirm pregnancy as a higher-phase temperature that stays elevated for 21 days or more after ovulation is indicative of pregnancy.
