LA Galaxy announce Sports Science and Performance Department staff

With support from Herbalife Nutrition, the LA Galaxy made key additions to the club’s Sports Science and Performance Department. Led by Pierre Barrieu, Director of Sports Performance, and Ivan Pierra, Director of Sports Science, the department will maximize performance, minimize injury risk, optimize fitness and nutrition levels and execute comprehensive training regiments for Major League Soccer’s premier club.

“This is a part of our technical staff that we were very focused on improving ahead of the 2018 season,” said LA Galaxy President Chris Klein. “As we strive to be the best in MLS, we have partnered with Herbalife Nutrition to invest in our Sports Science and Performance Department with the intention of putting our players in the best position possible to succeed.”

"Professional endurance athletes, like soccer players, have specific nutrition and hydration needs that enable them to perform at the highest level of their sport on an ongoing basis," said Dr. John Agwunobi, MD, MPH, MBA, Chief Health and Nutrition Officer at Herbalife Nutrition. "Our Sports Performance experts know that LA Galaxy players endure rigorous travel schedules and long practice sessions, so they work closely with the team to design a targeted sports nutrition and hydration program that helps them achieve peak performance on game day."

Barrieu, signed in August 2017, is the former Strength & Conditioning Coach for the U.S. Men’s National Team, serving time under Bruce Arena and Bob Bradley from 2002-06 and 2008-11 including three World Cup campaigns. In 2012, Barrieu was named United Arab Emirates National Team Assistant Coach and United Arab Emirates Football Association Head Fitness Coach.

At the club level, Barrieu spent the 2007 season under Bruce Arena with New York Red Bulls, 2014-15 with Sheffield Wednesday F.C. (England), 2015-16 with Le Havre AC (France) and 2016-17 with Swansea City A.F.C. (England).
