Force and postcontractile BOLD transient responses in anterior tibial muscle after 1-s maximal isometric ankle dorsiflexions

Active Sedentary
Peak BOLD, %change in SI 5.5±1.0 1.5±0.4*
Time to peak, s 6.7±0.5 5.8±0.3
Half relaxation, s 5.4±0.4 2.7±0.3*
MVC, N/cm2 22.7±1.5 19.4±2.0
End force, % initial 95.1±4.0 98.1±3.0

Values are means ± SE.

Indicates statistically significant difference between groups, Student’s t-test (P<0.05).

BOLD, blood oxygen level-dependent, MVC, maximal voluntary contraction; SI, signal intensity.
