After only 2 days of practice I decided to put Fragmented breathing to the test.
After 30 mins easy running I ran 4 x 1/2 mile loop [Selworthy rd] with 1 min rec between.
Running with an average Pulse rate of 125 bpm I got the following results
Lap one, normal breathing 6.40 pace average at 125 bpm
Lap two, fragmented breathing 6.33 pace average at 125 bpm
Lap three, normal Breathing 6.37 pace average 125 bpm
Lap four, F/B 6.32 pace average 125 bmp
Conclusion; Fragmented breathing allowed me to run 6 sec per mile pace [av] faster per 1/2 mile lap than normal breathing, with same pulse rate!
As it is said that 5 day minimum is required to fully learn the new breathing method more improvements should be possible:]
