Which test is a measure of reactive strength?

Countermovement jump

Drop jump

Squat jump

Which strength quality is unaffected by mechanical characteristics of muscle?

Fast dynamic strength

Explosive strength

Maximal isometric strength

What is the minimum duration for an athlete to apply maximal force during a maximal isometric strength test?

1 s

2 s

3 s

Which statement correctly describes how maximal isometric strength responds to training compared to heavy maximal dynamic strength?

They both respond comparably to training

Maximal isometric strength responds more to training than heavy maximal dynamic strength

Heavy maximal dynamic strength responds more to training than maximal isometric strength

Why do the authors restrict the definition of rate of force development (RFD) to high external load conditions?

Measures gained from the countermovement jump share little commonality to isometric RFD

RFD is a unique strength quality derived from either isometric or fast dynamic tests

Higher load during dynamic movements leads to a higher RFD compared to low-load conditions

What is the earliest time after onset that maximal strength is achieved in isometric conditions based on a typical force-time curve?

0.03 s

0.10 s

0.60 s

What is the purpose of utilizing a sufficiently brief time frame when assessing explosive strength?

Obtain a more precise measurement during testing

Distinguish it from the peak force measurement

To reduce the variable’s amount of new information

What is the most common test to measure fast maximal dynamic strength?

Mid-thigh pull

Back squat

Countermovement jump

 What is the reactive strength index?

Changes in fast maximal dynamic strength relative to maximal isometric strength

Changes in explosive strength relative to fast maximal dynamic strength

Changes in maximal isometric strength relative to explosive strength

What is a noted limitation of the drop jump test?

There is a substantial increase in injury risk to individuals

Extensive familiarization with the movement is needed

It is a poor method of assessing reactive strength
