How do physical therapists utilize lower amplitudes compared to strength coaches using higher intensity settings today?

Physical therapists might use lower amplitudes to gently stimulate circulation, while strength coaches use higher intensity for neuromuscular recruitment.

Modern application involves drawing selectively from the historical lineages—the mechanical understanding from Zander's time and the precise high-frequency data from the Space Age research—to tailor sessions for specific outcomes. Physical therapists often aim for gentle physiological responses in rehabilitation, meaning they might opt for lower amplitudes specifically to stimulate circulation in a recovering patient. In contrast, strength coaches prioritize maximizing performance outputs; therefore, they are more likely to employ higher intensity settings designed to achieve maximum neuromuscular recruitment necessary for achieving athletic gains.
