Methodological developments in the assessment of physiological responses to arm crank ergometry

This submission for PhD is based around a series of thematic and original research studies, which have been published during the past seven years (2001 to 2007), focused upon arm crank ergometry exercise testing. A number of topical issues have been considered, including: 1) the development of fundamental exercise protocols; 2) the assessment of oxygen uptake (VO2) kinetics; 3) the assessment of external power production during sprint arm crank ergometry, and 4) the design and implementation of novel equipment configurations and research designs. During preliminary testing we demonstrated that the selection of an imposed crank rate was an important consideration. In another study we also demonstrated that it was feasible to use either step or ramp incremental exercise tests for the purpose of establishing peak physiological responses during arm crank ergometry. Two further studies considered the measurement of external peak and mean power production during sprint arm crank ergometry. The first of these studies compared measurement techniques. A follow-up publication considered the reproducibility of uncorrected peak and mean values of power output. In the final publication an interdisciplinary approach was employed. This study examined how crank configuration (asynchronous vs. synchronous) affected the magnitude and pattern of muscle activity, and torque production at two work rates. Our findings demonstrated the complexity of arm crank ergometry as the activity of muscles of the arms, shoulders and legs became progressively involved as external work rate increased from 50 to 100 W. Based on parameters associated with the pattern of torque profile, it was speculated that the asynchronous crank configuration was more efficient for the group of able-bodied participants.
