FTP #20: Sara Oikawa, PhD – New developments in collagen research: implications for endurance athletes

Sara Oikawa, Ph.D.

Guest Bio

Sara earned a Bachelor of Science in Kinesiology, a Masters of Science in Kinesiology, and  Ph.D. in Kinesiology specializing in skeletal muscle metabolism and nutrition from McMaster University (Hamilton, Canada), under the supervision of Dr. Stuart Phillips. Sara’s research has spanned several populations (young and older adults, pregnancy, cardiac rehabilitation, elite athletes) though the focus of her Ph.D. was to examine the role of protein quality and physical (in)activity in healthy older adults.
