More Sprint Fun

Julio and Jorge cranking out kipping pullups and attempts from yesterday's WOD

TUESDAY WOD

12 x 20 second sprints--all out efforts

2 mins rest in between

"Why is there so much anaerobic/sprint/speed work if I am going to run/ride/swim in a long endurance event?

Anaerobic/sprint/speed work, often thrown in at the end of many traditional training programs as a supplement, incorrectly assumes that this type of training is of limited value.
"Anaerobic Training" has the following benefits and drawbacks:

BENEFITS


• Increased cardiovascular function

• Decreased body fat
• Increased muscle mass
• Increased strength
• Increased power
• Increased speed

• Increased anaerobic capacity


DRAWBACKS

• Intensity can speed up overtraining
 

 
 
Studies demonstrate that the adaptations caused by anaerobic training are similar to high volume endurance training, however, this adaptation comes at much lower training volumes! (Similar metabolic adaptations during exercise after low volume sprint interval and traditional endurance training in humans. J Physiol. 2008 Jan 1;586(1):151-60. Epub 2007 Nov 8.)"
