Energy Systems - What you need to know

​In this video, Jess Collins Ph.D. discusses what rowers need to know about energy systems for racing and training. Jess is a medical neuroscientist and competitive ultra-marathoner.
You will learn:

• What the three main energy systems are
• How your body produces and uses energy during training and racing
• Where lactic acid comes from
• How lactate levels affect fatigue
• How your aerobic system fights fatigue
• How quickly each energy system works
• How efficient each system is
• What your lactate threshold is
• What pyruvate is and how your body uses it
• Why we shouldn't do high-intensity training all the time
• How long it takes to make positive fitness changes in each system
• How long you can expect the fitness of each energy system to last following injury or inactivity
• The optimal amount of low vs. high-intensity training you should do
• If training volume should be measured in duration or distance
