Please follow the Explain direction on doing this pro's and con's 2 scholarly sources needs.

Explain how the evidence that your peers have presented either shows strong support for their conclusions or weak support for their conclusions. Be sure to present counter-evidence or corroborating evidence when possible.  You must use at least two scholarly sources to support your explanation. 

There are pro's and con's to using non-nutritional, non-pharmacologic procedures that enhance physiologic responses to exercise and increase performance, and also aid in recovery after exercise.  The one I would rank first for effectiveness and appropriateness is warming-up.  A warm up will not only get your muscles moving, but will also open your oxygen pathways, making it easier while running.  The pros of procedure is the it "prepares you physiologically and psychologically for an event" (Katch, McArdle, Katch, 2015), while also reducing the likelihood of getting injuries.  There are really no con's to warming up for an event.  The procedure that I would rank number two is Red Blood Cell Reinfusion (RBC), or blood boozing.  This procedure came about during the Munich Olympics in 1972 (Knatch, McArdle, Knatch, 2015).  This procedure will benefit long distant runners, who really need the oxygen to complete the run.  The pros to RBC is adds "100 ml of oxygen to the bloods total oxygen-carrying capacity," however the downfall is it can reduce aerobic activity as well (Katch, McArdle, Katch, 2015).  If you get an infusion that is in an amount that is too large, that can in turn cause an increase in blood thickness, causing a decrease in cardiac input.  The third ranking procedure is the Erythropoietin procedure, which is a hormone that is produced by our kidneys (Katch, McArdle, Katch, 2015).  This procedure stimulates your body's bone marrow causing the increase of production of the RBC's, which combats anemia in patients who are suffering from kidney disease. Erythropoietin has also been studied to help bone growth, after a break, so a small dose medically, is not bad for the bones (Rolfing, 2014).  A con, however, is that too much Erythropoietin can because for heart attack, heat failure, and even death (Katch, McArdle, Katch, 2015).  The procedure that I would rate fourth is the breathing of hypertoxic gas, or hypertoxic gas mixtures.  This is known to enhance the bloods oxygen-carrying capacity, while also helping the body's recovery.  The pro's to breathing hypertoxic gas is it enhances endurance and performance, while it does not alter the heart rate or serum lactate for performance (Katch, McArdle, Katch, 2015).  The procedure that I would recommend to the athlete is the warm-up procedure.  This procedure in the high climate of Denver, CO will get my client ready to go for his/ her big day for the marathon.
