Brief Summary:
Army ROTC Cadets who are currently enrolled in Military Science courses will be asked to participate in this experimental research design A total of 30 healthy cadets consisting of approximately 24 males and six females will be recruited as this will provide an accurate representation of the overall Army demographics with 17 being female
Paperwork After providing consent participants age and gender will be documented and height and weight will be measured and documented Participants will complete a modified version of the Modified Oswestry Low Back Pain Disability Questionnaire which has been adjusted to be more specific to the military population The questionnaire will be filled out indicating the cadets current level of pain They will then complete the same questionnaire indicating their pain within the last year
Protocol First the skin will be prepared and surface electromyography EMG electrodes will be placed Dynamic surface EMG data will be obtained of the gluteus medius gluteus maximus erector spinae rectus femoris and biceps femoris muscles in accordance with SENIAM Surface Electromyography for the Non-Invasive Assessment of Muscles guidelines Skin preparatation will consist of trimming hair if the skin surface at which the electrodes have to be placed is covered with hair Next the skin will be cleaned with alcohol The skin will be allowed to dry prior to electrode placement Lastly skin will be abraded to reduce impedance Following electrode application participants will complete five minutes of light activity on a bike or treadmill for warm-up Next in order to normalize the data manual muscle tests will be performed for each of the six muscles being test Then participants will walk at a speed of four miles per hour for 10 seconds as a dynamic measurement for normalizing the data
After completion of the two normalization protocols participants will complete a five kilometer 31 mile walk on a treadmill at a speed of three miles per hour with and without a 35 lb load carried in a traditional rucksack The load conditions will be randomized and counterbalanced in order to mitigate effects of fatigue and the conditions will be performed in two separate sessions separated by 24-48 hours
