The Effects Of The Fifa 11+ Warm Up Program In Female Collegiate Soccer Athletes, Stacey O’Neill May 2016

The Effects Of The Fifa 11+ Warm Up Program In Female Collegiate Soccer Athletes, Stacey O’Neill

Graduate Theses

As of 2010 there were over 265 million registered soccer athletes worldwide, and in particular, the number of women players were rapidly increasing (Soligard, et al., (2010). Consequently, playing soccer accounts for approximately one quarter of all injuries in sport, and due to its nature of jumping, pivoting and cross-cutting, the majority of these are non-contact, lower extremity injuries. Therefore, playing soccer entails a substantial amount of injury risk for its participants. The purpose of this study was to investigate the effects of the FIFA 11+ Warm Up Program in collegiate female soccer athletes.

Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams Jan 2012

Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams

Electronic Theses and Dissertations

Phosphatidic Acid (PA) is a natural phospholipid compound derived from lecithin which is commonly found in egg yolk, grains, fish, soybeans, peanuts and yeast. It has been suggested that PA is involved in several intracellular processes associated with muscle hypertrophy. Specifically, PA has been reported to activate protein synthesis through the mammalian target of rapamycin (mTOR) signaling pathway and thereby may enhance the anabolic effects of resistance training. To our knowledge, no one has examined the effect of PA supplementation in humans while undergoing a progressive resistance training program. To examine the effect of PA supplementation on lean soft tissue …
