1 Subject Preparation |
Subject preparation: all subjects should wear shorts, females wear a sports bra or bathing suit top, no socks or shoes should be worn; place a.reflective marker on the camera side of the body at the apex of the lateral iliac crest, ASIS, PSIS, greater trochanter, lateral joint line of the knee and lateral malleolus; place one EMG electrode over each rectus abdominus proximal and distal attachment sites; data logger belt should be positioned next to the non-camera side of the subject during filming |
Subject preparation: all subjects should wear shorts, females should wear a sports bra or bathing suit top, all subjects should wear low cut socks and sneakers; place a reflective marker on the camera side of the body at the ASIS, PSIS, greater trochanter, lateral joint line of the knee and lateral malleolus; place one EMG electrode each on the proximal attachment of the rectus femoris, the distal quad tendon, mid-belly region of both the semitendinosus and the biceps femoris; data logger belt should be placed on a stand positioned next to the non-camera side of the subject during filming |
Subject preparation: all subjects should wear shorts, females should wear a sports bra or bathing suit top, all subjects should wear low cut socks and sneakers; place a reflective marker on the camera side of the body at the inferior angle, superior angle and acromium process of the scapula, the lateral epicondyle of the humerus and the styloid process of the distal radius; place one EMG electrode on the mid-section of the rhomboid and one on the mid-section of trapezius II and IV; data logger belt will be worn on the subject’s waist |

2 Camera Positioning |
Videocamera position: perpendicular to the lumbar region of the trunk such that all 6 reflective marders are visible in viewfinder; position cloth backdrop behind the calisthenic mat | Videocamera position: perpendicular to the side of the weight lifter such that 6 reflective markers are visible in the viewfinder; position cloth backdrop behind the chair squat location | Videocamera position: on a diagonal path with the body (posterior right quadrant between the sagittal and frontal planes) such that all 5 reflective markers are visible in the viewfinder; position backdrop curtain so that it faces the camera |
