Factors Influencing movement and performance

What is the most likely cause of fatigue in a runner completing a 100 m sprint?

• dehydration

• accumulation of lactic acid

• depletion of muscle glycogen

• depletion of phosphate creatine

The anaerobic glycolytic energy system:

• operates with oxygen

• provides energy for just over 2 minutes

• uses the breakdown of glycogen in the absence of oxygen

• is used in short maximal events such as shot put and high jump

An elite 10 000 m runner would predominantly use which energy system during a race?

• ATP-PCr energy system

• anaerobic glycolysis energy system

• aerobic energy system

• adenosine triphosphate

Which of the following fuels are used to produce energy most at rest?

• carbohydrates

• proteins

• fats

• ATP

Fartlek training consists of:

• a series of explosive exercises

• a series of exercise stations arranged in a specific order

• a steady, low intensity exercise over a long period of time

• a continuous steady state aerobic exercise with higher intensity periods or efforts

Short- to moderate-interval training is best used to improve which type of fitness?

• aerobic fitness

• strength and power

• muscular endurance

• anaerobic fitness

The lactate threshold is defined as:

• the maximal exercise intensity an individual can maintain with little or no lactate accumulation for an extended period of time

• the point at which blood lactate begins to accumulate in large quantities in the blood

• the point at which lactate starts to decrease in the blood

• the point at which lactate accumulation is higher than lactate removal

An individual’s highest possible oxygen consumption during exercise is identified as:

• VO2 max

• lung capacity

• oxygen uptake

• lactate threshold

What testing procedure is most valid for a basketballer?

• sit and reach test

• 1.6 km time trial

• stork stand

• vertical jump and medicine ball throw

Which of the following is the best test of speed?

• vertical jump

• 1.6 km time trial

• Illinois agility test

• 40 m sprint
