Despite the unique opportunity race car driving provides to study exercise in extreme conditions, the sport of racing is under-represented. A better understanding of how racing changes physiological measures combined with driver demographics may help reduce driver risks and expand the field of driver science. This study charted the changes in heart rate, body temperature, blood pressure, static oxidation reduction potential (sORP), and antioxidant capacity in drivers before and after racing (n=23). The interaction between racing and driver characteristics on physiological variables were evaluated. Heart rate, body temperature, and sORP were elevated after racing (P0.05). Elevated post-race sORP values were associated with higher pre-race systolic blood pressure and lower antioxidant capacity (P

E-05 Summary THREE-DIMENSIONAL VECTOR INFIDELITY CORRECTIONBY GENERALLINEARTRANSFORM J. DELLINGER R. CLARKE and P. GUTOWSKI BP UTG 200 Westlake Park Blvd Houston Texas 77079 “Vector infidelity” is the failure of a multicomponent geophone to respond isotropically to incoming seismic energy. We model vector infidelity as a linear minimum-phase multichannel filter that the geophone and its immediate environment apply to the incoming seismic signal. Our goal is to determine the inverse of this filter so that we can restore vector fidelity. We begin by identifying arrivals in the data with known (or at least assumed known) polarizations. If the model is valid
