The main parameters that are automatically calculated by the isoforce software are the
following.
Torque – force producing a rotary motion. Force applied at the axis of rotation as measured by the
dynamometer.
Peak Torque – highest muscular force output at any moment during a repetition. Indicates the muscles
maximum strength capabilities.
Mean Torque – average value of torque during the whole repetition.
Peak Torque to Body Weight – ratio displayed as a percentage of the maximum torque production to
the subjects body weight. This percentage is used to compare with normative data.
Time to Peak Torque – measure of time from start of the muscular contraction to the point of highest
torque development. An indicator of the muscle functional ability to produce force quickly.
Time from Peak to Relaxation – measure of time from the point of highest torque development to the
end of the muscular contraction. An indicator of the muscle functional ability to relax quickly.
Position of Peak Torque – point in the range of movement where peak torque is achieved. Peak torque
will usually occur at nearly the same position for similar movements and speeds.
Coefficient of Variance (CV) – ratio between the standard deviation of a data set (our data set: peak
torque values) and the mean value of that set. This is expressed as a percentage to objectively
determine the reproducibility of test data. Large percentages of coefficient of variances could be related
to underlying factors such as pain, apprehension or lack of instruction. Large muscle groups should
have a CV of 15% or below to be within normal limits and small muscle groups should be 20% or below
to be within normal limits.
Work – force multiplied by distance. Indicates the amount of tension produced by a muscle. On a graph,
work is noted as the area under the curve regardless of speed, time or range of movement.
Work to Bodyweight Ratio – ratio displayed as a percentage of the work repetition to the subjects
bodyweight.
Total Work – sum of work for every repetition performed in the exercise. Indicates the endurance
capabilities of a muscle group by evaluating the ability to maintain work.
Fatigue Index – ratio of the difference between the work carried out in the first three repetitions
compared to work in the last three repetitions. Valuable in documenting progress during endurance
training to detect the amount of fatigue throughout the exercise.
