What does MF stand for?

The springy blades reduce the muscle forces Pistorius requires for sprinting to less than half of intact-limb levels.

The springy, lightweight, J-shaped limbs called "Cheetahs" allow Pistorius to attain the same sprinting speeds with 20 percent less ground force than able-bodied runners, and reduce to less than half the muscle force required for sprinting, the researchers said.

Isokinetic evaluations of maximum muscle strength reveal that more muscle force is produced at slower movement speeds.

Developing proprioception and incorporating intrinsic timing with muscle force are essential for accurately performed functional activity.

Methods: Physical activities in daily life (activity monitoring), pulmonary function (spirometry), exercise capacity (incremental cycle-ergometer testing and 6-min walk distance testing), muscle force (quadriceps and handgrip force, and inspiratory and expiratory maximal pressures), quality of life (chronic respiratory disease questionnaire), and functional status (pulmonary functional status and dyspnea questionnaire-modified version) were assessed at baseline, after 3 months of a multidisciplinary rehabilitation program, and at the end of a 6-month multidisciplinary rehabilitation program in 29 patients (mean [[+ or -] SD] age, 67 [+ or -] 8 years; [FEV.

Furthermore, at post 2, contractile RFD remained reduced in the later phase of rising muscle force (time interval, 0-200 ms; -19.

Alterations in inspiratory and leg muscle force and recovery pattern after a marathon.

Ribose supplementation did not affect subsequent muscle force production after 60 min of recovery.
