CR
The decline in cardio fitness happens at this rate compared to the loss of muscle strength or power
What is faster?
One purpose of warming up is to raise this in the muscles before exercise
What is temperature?
Having more body fat can slow this process that helps keep your body cool
What is heat loss?
This type of fitness measures how well your heart and lungs supply oxygen during long periods of exercise
What is cardiorespiratory endurance?
You do this when you have a cramp or cramps start to form
What is stretching?
Cardio fitness levels start to noticeably decline after this amount of time without training
What is 2–3 weeks?
This is the main limiting factor when your muscles get tired during repeated contractions over time
What is anerobic capacity?
This state occurs when long-term overtraining leads to drops in performance and health.
What is overtraining syndrome?
This training principle means practice and workouts should mimic game-day conditions for the best results.
What is specificity?
This kind of stretching, involving movement through range of motion, is best right before competition.
What is dynamic stretching?
This well-known equation predicts your maximum ability to use oxygen during exercise
What is the Fick equation?
Early strength gains from a new training program come mostly from
What is improved neuromuscular skill?
To make training harder without adding more intensity or time, you could reduce this aspect of your workouts
What is recovery time?
This is the name for the longest phase of training, covering the whole season or year
What is a macrocycle?
A muscle that moves easily through its range of motion uses less energy. This describes what trait?
What is flexibility?
This type of athlete benefits most from a cool-down to help clear waste products from the muscles
What is a middle-distance runner?
Strength loss from stopping training is mostly due to reduced activation of these muscle fibers.
What are type IIx fibers?
This buildup in the blood and muscles is one reason endurance performance drops during fatigue
What is lactic acid?
This level of training load is challenging enough to cause improvement, but not too hard to cause burnout.
What is acute overload?
This is one reason why holding a stretch for too long can make muscles weaker temporarily
What is reduced ability to store elastic energy?
Very short, near-max effort intervals help build this energy system.
What is the phosphagen system?
Anaerobic athletes who do too much cardio may see this change in muscle size
What is smaller muscles?
The ratio of these two hormones is used as a marker to see if an athlete is overtrained
What is testosterone to cortisol?
To train the creatine phosphate system, this long passive rest is recommended between short sprints
What is a 1:12 work-to-rest ratio?
This phenomenon explains why power is not reduced after using moving stretches before a workout.
What is post-activation potentiation?
