It was hypothesized that the increasing eccentric workloads would result in greater eccentric muscular contractions and increased metabolic cost. Methods: The research design of this study was experimental. Ten subjects (5 male, 5 female) were acquired through a convenience sample. The two exercise trials – full body row (FBR) and low body row (LBR) – each consisted of a 12-minute rowing session that included four stages. The eccentric workload, determined by average power (W), increased with each stage while the concentric workload remained constant throughout the entire test. Electromyography (EMG) data was collected through the Delsys EMG System for eight muscles (rectus femoris (RF), gastrocnemius (MG), tibialis anterior (TA), biceps brachii (BB), trapezius (LT), and latisimus dorsi (LD)). Metabolic data was collected through the COSMED K4b2, while heart rate (HR) was monitored through a Polar heart rate sensor. Results: Oxygen consumption significantly increased between stages 1 and 2 for both the FBR (p = .000(1)) and LBR (p = .004), with no significant increases revealed between the remaining stages. However, heart revealed to significantly increase with each stage (p < .05) for both configurations. Muscle activation also significantly increased in some muscle groups (RF, BB, LD) between stages on the FBR and some muscles (RF, BF, and TA) of the LBR, but not for the others. However, an overall increase in muscle activation was seen for all muscle groups through each increased eccentric workload. Conclusion: The powered rowing machine, through its robust controllable impedance, can be effective in creating a more complete, dynamic, and high intensity mode of exercise. This allows the apparatus to be applicable to exercise equipment needed for both rehabilitation and countermeasures to microgravity. 2018-08-22 English text Cleveland State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=csu1534697072520532 http://rave.ohiolink.edu/etdc/view?acc_num=csu1534697072520532 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
