Fatigue Index describes how much performance declines across repeated efforts or across a sustained high-intensity test. It is commonly used in repeated sprint tests, Wingate-style anaerobic testing, repeated strength tests, isokinetic endurance testing, repeated jumps, force testing and sport-perfo...

Time to Peak measures how long it takes a client to reach the highest value in a test. Depending on the assessment, this may refer to time to peak force, time to peak torque, time to peak power, time to peak velocity or another peak output.

In force and torque testing, Time to Peak helps profession...

Rate of Force Development, commonly abbreviated as RFD, measures how quickly force is produced. It is one of the most useful force-time metrics when a professional wants to understand not only how much force a client can produce, but how fast they can produce it.

Peak force tells you the highest fo...

Rate of Torque Development, commonly abbreviated as RTD, measures how quickly torque is produced around a joint. In simple terms, it shows how fast a client can generate joint-specific rotational force.

Torque tells you how much rotational force a client can produce. RTD tells you how quickly they ...

Torque measures the rotational effect of force around a joint or axis. In strength testing, it helps describe how much turning force a client can produce around a joint, such as the knee, hip, ankle, shoulder or elbow.

Torque is commonly used in isometric testing, isokinetic dynamometry, handheld d...

Peak force is the highest force a client produces during a test. It is commonly used to assess maximal force capacity during strength assessments, isometric tests, force plate testing, handheld dynamometry, load cell testing, push-pull assessments and performance testing.

Peak force can be recorded...

Blood pressure measures the pressure exerted by circulating blood against artery walls. It is recorded as two values: systolic blood pressure and diastolic blood pressure, written in millimetres of mercury, or mmHg.

Blood pressure is one of the most important vital signs because it can support base...

Impulse describes the total force applied over a selected period of time. In force-time testing, impulse is calculated as the area under the force-time curve. In simple terms, it reflects both how much force a client produces and how long that force is applied.

Impulse is commonly used in force pla...

Pulse rate measures the number of heartbeats per minute and is one of the most widely used vital signs. It can support baseline screening, exercise monitoring, recovery tracking, safety decisions and comparison over time.

For most resting adults, 60–100 beats per minute is commonly used as a practi...

Respiratory rate measures the number of breaths a person takes per minute. It is a simple but important vital sign that can support safety, exercise monitoring, health screening and clinical reasoning. It should be interpreted with symptoms, oxygen saturation, pulse rate, blood pressure, temperature...

The Body Temperature Test records the client’s temperature in degrees Celsius. It can help provide context when a client feels unwell, has recent illness symptoms, has been exposed to heat or cold, or needs a baseline vital sign recorded before assessment or training.
