TESTING PROTOCOL

Each subject of each experimental group was tested twice. During the first test the subject was thoroughly briefed on the testing procedure. The subject then read through a Briton consent from and signed it to acknowledge that the expected benefits and potential risks of participation in the study were fully understood.

Control Group

Each subject in the control group was tested twice with at least 48 hours, but no more than one week between testing sessions. The subjects were asked NOT to stretch or participate in any strenuous physical activity prior to arriving for testing. Before data collection began, the subject was allowed two full practice swings. The subject was then asked to hit five golf balls using a driver.

'Machine Assisted' Passive Stretch (MAPS) Group

Each subject in the MAPS group was tested twice with at least 48 hours, but no more than one week between testing sessions. The subjects were asked NOT to stretch or participate in any strenuous physical activity prior to arriving for testing. Before data collection began on one f the two testing sessions the subject was asked to perform the MAPS routine on the BackSystem3. The sequence of stretching was randomly varied from the first test to the second test to ensure that no biases were created. The subject was allowed two full practice swings. The subject was then asked to hit five golf balls using a driver.

Static Stretch Group

Each subject in the control group was tested twice with at least 48 hours, but no more than one week between testing sessions. The subjects were asked NOT to stretch or participate in any strenuous physical activity prior to arriving for testing. Before data collection began on one f the two testing sessions, the subject was asked to perform the static stretch routine. The sequence of stretching was randomly varied from the first test to the second test tense that no biases were created. The subject was allowed two full practice swings. The subject was then asked to hit five golf balls using a driver.
