Heart rate monitors - training load for each player. How much time each player spends in their 90% zone. How their fatique is building up. The Sounders are using an Omega wave system this pre-season to determine how hard players need to be working. Sounds like quite the professional outfit.
The Sounders have been in Casa Grande, Arizona for a week now and in training camp since January 25. Sigi Schmid knows this is a long preseason and is using technology and experience to prepare his team for the long MLS season. The Sounders also head to Spain for some preseason match where Zigi Schmid said they'd also get a day off.
