SPORT SCIENCE

Tyler is an active sports science consultant for the Seattle Seahawks, and a well established author in the field of exercise physiology.  

Tyler initially studied pulmonary physiology under Dr. Andrew T. Lovering, where his research focused on the lungs adaptations to different stressors, whether it be smoking, exercise, or high altitude. 

Next, Tyler studied under Dr. Markus Amann and Russell Richardson, where his research primarily focused on fatigue and the cardiovascular system.

Tyler has over 30 combined publications and abstracts on a variety of sports science topics, ranging from fatigue to aging, to the cardiovascular system.  Tyler also provides private lectures for a range of audiences. For a full list of lectures and publications, please see below.
