Some quick literature review has also postured the following- 

	• "circulatory changes and changing blood flow volume to ventricles in the heart during exercise can trigger an autonomic response that may cause nausea and vomiting. Vigorous exercise reduces the flow of blood to the gastrointestinal tract, which reduces its resilience, and can make you more prone to nausea, vomiting and related problems..." * Cut and pasted from the "Livestrong.com"" website and reconfirmed in the following journal:
	• "Nausea and Vomiting: Recent Research and Clinical Advances"; John Kucharczyk, et al; 1991	

	• Rowers, canoeists, and weight lifters can sometimes develop nausea and gastrointestinal issues because of the constant flexion and contraction of the abdominal cavity.
