The Claim

Daily 30-minute artificial gravity exposure via centrifugation attenuates the increase in evoked twitch contraction speed in knee extensors and reduces the loss of twitch peak torque in plantar flexors induced by bed rest, but does not prevent the decline in maximal voluntary strength.

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Daily 30-minute exposure to artificial gravity generated by centrifugation reduces the speed increase in knee extensor muscle twitches and lessens the loss of peak torque in plantar flexor muscles during bed rest, but does not stop the reduction in maximal voluntary muscle strength.

See the scientific wording

Daily 30-minute artificial gravity exposure via centrifugation attenuates the BR-induced increase in evoked twitch contraction speed in knee extensors and reduces the loss of twitch peak torque in plantar flexors, but does not prevent the decline in maximal voluntary strength.

Why this might work

Daily spinning in a machine while lying down keeps muscle cells from speeding up their relaxation too much and prevents some loss of muscle twitch strength by maintaining normal calcium control and reducing damage at the nerve-muscle connection. It does not stop overall muscle weakness because it doesn't prevent the muscle fibers from shrinking.

  1. Study: Muscle Weakness and the Irisin–BDNF and Oxidative Stress Axis in the 60‐Day Pseudorandomised Controlled AGBRESA Bed Rest Study

    Spinning in a machine for 30 minutes a day while lying down helped slow down unwanted speed-ups in thigh muscle twitches and saved some calf muscle strength during bed rest, but it didn’t stop people from becoming weaker overall.
