Predicting walking METs and energy expenditure from speed or accelerometry

Article Abstract:

Anattempt is made to examine whether speed display a stronger association with level terrain walking METs and energy expenditure than Computer Science Applications accelerometer positioned on the hip (CSA(sub hip)). It is concluded that speed-based MET and energy expenditure predictions during level terrain walking are more accurate than those utilizing CSA(sub hip).

Rectal temperature correction overestimates the frequency of exercise-induced hypoxemia

Article Abstract:

Exercise-induced hypoxemia (EIH) occurs in an unknown ratio of endurance trained athletes and the normally used rectal temperature readings may not be suitable. The proportion of athletes fitting in the description of EIH depends on the location of core temperature measurement.

CPX/D underestimates VO(sub)2 in athletes compared with an automated Douglas Bag System

Article Abstract:

Research shows that oxygen consumption values in athletes determined by the Medical Graphics CPX/D system are about 11% lower than the automated Douglas Bag System. Data indicate that the discrepancy is not due to inaccuracies in volume measurements.
