curious about this subject..... i think i read about both tennis and baseball players taking ice baths after a long, hard match... and i've seen them do it on that stupid MTV reality show about that high school football team in alabama....... seems to really work. and i don't know about you guys, but my back is often really sore after 2 hours of playing (and i think that's relatively true of pro's when it's over 2 hours - see agassi or bagh from last USO). anyone done this?? can i produce enough ice to make my bath water "cold enough"??................. i have been doing hot baths which seemingly is the exact opposite and seems to work o.k, not great though..... can someone explain the therapeutic difference between ice and heat on sore, tired muscles? (NOT injured muscles, i know that's ice followed later by heat. thanks in advance!!
