The purpose of this study was to investigate the impact of CWI (cold water immersion) on dynamic balance and anaerobic power, as well as neuromusculsr changes in karate kumite fighters after acompetition. EMG was measured using a Biometrics Ltd DataLINK and SX230 EMG sensors. A RMS (root mean square filter was applied to the data using the Biometrics Ltd DataLINK software.

Eight EMG sensors are applied over pre-determined muscle locations on each subject; all eight EMG sensors are connected to one DataLOG unit which is subject worn. Subjects are instructed to follow an activity protocol while data is collected. Data is statistically analysed to determine the relationship between subject age and muscle activity including co-contraction. Results are presented and discussed.

Knee joint proprioception is analysed in this study on healthy subjects. Joint position sense (JPS) data collected using the Biometrics Ltd Goniometers, is used to analyse the stability of the knee joint. Throughout the duration of the study, subjects wearing Goniometers recreated determined joint angles to assess the relationship between joint angle and risk of injury.

Knee Goniometer data is fundamental in determining the relationship between stretching and knee joint position sense. Biometrics Ltd Goniometers are applied to the knee joint of each study participants who were instructed to recreate a specific knee joint angle before and after a period of stretching. Results are discussed and compared with existing research.

This ergonomics study evaluates two 'carpet weaving' workstations and the effect that each has on shoulder EMG activity. Biometrics Ltd EMG sensors are applied bilaterally to the shoulder muscles of subjects, EMG sensors are connected to the DataLOG unit and data is collected over a four hour period for each workstation. A statistical analysis highlights the benefits of the ergonomically designed workstation and a brief discussion identifies the hazards of the traditional workstation, all conclusions are supported by the EMG data collected.

Biometrics Ltd Goniometers are used to monitor knee flexion during this study to document the effects of exercise on patellofemoral pain syndrome (PFPS) sufferers. Data was collected before and after a six week period so that a statistical analysis could be carried out comparing results from the control group with the exercise group. The Goniometers were placed on the leg of participants from both subject groups; knee flexion was recorded for a stair climbing activity while pain scores were communicated.
