Eccentrics metrics available in the FLEX app

Eccentric Mean Velocity (m/s)

• This is the average velocity that was obtained over the eccentric phase of the lift. It is calculated by summing the individual velocities for each data point and dividing by the number of data points obtained in the eccentric phase of the lift. The following equation is used to calculate velocity.
  V = Change in d/change in t.
  Where v = velocity, d = distance and t= time i.e. (d2-d1) / (t2-t1)
• Displayed as metres per second

Eccentric Peak Velocity (m/s)

• This is the peak velocity measured over the eccentric phase of the lift. It is an instantaneous value, measured over a sample period of approximately 20 milliseconds.
  The following equation is used to calculate velocity.
  v = Change in d/change in t
  Where v= velocity, d = distance and t= time i.e. (d2-d1) / (t2-t1)
• Displayed as metres per second

Eccentric Time (seconds)

• This is the duration of time taken to complete the eccentric (lowering) phase of an exercise.
  T =(t2-t1) where t = time in seconds, t1 = time at start of eccentric phase t2 = time at finish of eccentric phase
• Displayed as seconds
