Adaptive active training system

An adaptive active training system, comprising:

• a motion module, comprising:
• a training unit;
• and
• a motor connected to the training unit, the motor being configured to bring the training unit to move along a motion trajectory;
• a sensing module configured to sense a physiological signal of a user when the user uses the training unit;
• and
• a control module connected to the motion module and the sensing module, the control module being configured to:
• calculate a position of the training unit on the motion trajectory;
• obtain a threshold value corresponding to the position based on a motion model;
• and
• determine whether a magnitude of the physiological signal is greater than the threshold value, wherein:
• when the magnitude of the physiological signal is greater than the threshold value, the control module drives the motor to bring the training unit to move along the motion trajectory;
• when the magnitude of the physiological signal is greater than a product of the threshold value and a magnification ratio, the control module raises the threshold value to an increased threshold value based on a learning rate;
• when the magnitude of the physiological signal is less than the threshold value, the control module does not drive the motor to bring the training unit to move along the motion trajectory;
• and
• when the magnitude of the physiological signal is less than the product of the threshold value and a reduction ratio, the control module lowers the threshold value to a decreased threshold value based on the learning rate.
