Replication Data for: Older adults with pre-sarcopenia/sarcopenia have increased gastrocnemius muscle activity to maintain upright postural control at stance perturbation

Fourteen older adults with pre-sarcopenia/sarcopenia and fourteen without sarcopenia. Sarcopenia was identified according to European Consensus on Definition and Diagnosis (EWGSOP) criteria. Ten balance perturbations were applied. Variables analyzed: Latency for peak of center of pressure (CoP), CoP velocity, latency time and electromyographic (EMG) amplitude.
