EORS_FTT
During the Jump Down Test, subjects used a two-footed hop to jump from a height of 30 cm and land on a force plate to measure the peak vertical impact force on landing (Kistler, model 9286A, Kistler Instruments, Winterthur, Switzerland).

EORS_FTTMP
A force plate was used during upper and lower body testing to determine force. The leg press machine was equipped with a force plate (Type 9281C, Kistler, Amherst, NY) as was the Plyometric Power System (Fitness Technology), which includes two force plates (Type 9286, Kistler) that were placed under the bench to measure force output during testing.

EORS_FOI
A force plate was used during lower body testing to determine force. The leg press machine was equipped with a force plate (Type 9281C, Kistler Instrument Corp., Amherst, NY), position transducer (PT5A, Fitness Technology, Skye, SA, Australia), and magnetic braking system (Fitness Technology, Skye, SA, Australia). During the strength test, subjects were instructed to place their feet gently on the force plate and then, on command, reach maximal isometric force as quickly as possible and hold it for approximately three to five seconds. Force data was sampled at 1000 Hz and filtered at 4 Hz.

EORS_Exercise_ARED
Ground reaction force (GRF) data were collected at 1000 Hz during each lift. GRF were collected using two 40x60cm quartz crystal piezoelectric force plates (Model 9261, Kistler Instruments AG, Winterthur, Switzerland,) positioned under each leg. The force platforms were connected directly to the BTS Motion Capture system via an interface box. GRF and motion capture data were captured simultaneously by the motion capture system.
