Implication

Alerts clinicians to contraction-specific fatigue in rehab; leaves open validation in patient populations.

Structured PICO

Population

Ankle dorsiflexor muscles (subjects not specified in abstract)

Intervention

Fatigue tests performed during concentric (CON) conditions (five sets of 30 maximum voluntary contractions at a constant speed of 50 degrees/s for a 30 degrees range of motion of the ankle joint)

Comparator

Fatigue tests performed during eccentric (ECC) conditions

Outcome

Loss of force and decrease in EMG activitysurrogate

Concentric contractions induce greater alterations in contractile properties than eccentric contractions, indicating a greater effect on intracellular Ca(2+)-controlled excitation-contraction coupling processes.
