Mechanomyographic responses of the vastus medialis to isometric and eccentric muscle actions

Article Abstract:

The mechanomyographic (MMG) amplitude and mean power frequency (MPF) versus torque relationships during isometric and eccentric isokinetic muscle actions are discussed. The results indicate that the patterns for MMG amplitude and MPF may reflect the motor control strategies that modulate torque production for isometric and eccentric isokinetic muscle actions.

A new nonexercise-based VO(sub 2max) equation for aerobically trained females

Article Abstract:

Modification of previously published VO(sub 2max) equations using the constant error (CE) values for aerobically trained female is presented. The new equation is cross-validated using the predicted residual sum of squares (PRESS) statistic and an independent sample of aerobically trained females.

Effect of mathematical modeling on the estimation of critical power

Article Abstract:

Results indicate that estimation of the time to exhaustion during cycle ergometry based on critical power generally overestimates the power out put needed to maintain the physical activity for at least one hour.
