1. Technical description
System consists of 2 functional components: Sensor Unit and Microcomputer
Sensor Unit is connected to the weight by a kevlar cord with a strap on a Velcro.
In weight exercises, muscles lift a mass
m
by applying a force
F
at a velocity
v
, produces average
power
P
.
F = m x g
P = F x v
System measures vertical Average and Peak Velocity of the weight lifted.
Using known mass system also calculates Average Power, Peak Power and Peak Force
in concentric phase of weight training.
To calculate Peak Power and Peak Force system uses equation:
P = F x v
, where
F = (m x g) + (m x a) ,
g-acceleration of gravity and a-acceleration
System also measures downward average velocity and rest time between reps or sets.
