Key Points MIT research shows muscle contraction releases myokines, enhancing neuron growth and nerve healing. Both chemical signals and physical forces from exercise stimulate neuron growth. Exercise-induced neurons showed enhanced gene expression for growth and communication. Research could lead to treatments that use muscle stimulation to aid nerve repair and mobility restoration. MIT engineers have uncovered a new benefit of exercise, showing that it can aid neuron growth and potentially help repair damaged nerves. Their research found that muscle contractions...
