The invention relates to the technical field of dorsal
muscle training, and particularly discloses a tensile dorsal
muscle trainer for
physical education, which comprises a stabilizing frame, a seat
cushion and a counterweight frame, the stabilizing frame is connected with the counterweight frame, the stabilizing frame is connected with the seat
cushion, a plurality of counterweight blocks are placed on the counterweight frame, the stabilizing frame is connected with a traction
rope, the traction
rope is connected with a quantitative rod, and the quantitative rod is connected with the quantitative rod. A plurality of first pulleys are connected to the stabilizing frame, a traction
rope is connected to the first pulleys, the other end of the traction rope is connected with a
handle, an adjusting
assembly is connected to the stabilizing frame, the adjusting
assembly adjusts the height of the
handle according to the height of a user, the situation that the position of the
handle does not correspond to the position of the user is prevented, and the situation that the
training effect of the user is affected due to nonstandard training postures of the user is prevented. The
trapezius muscle is excessively used in the training process of a user,
trapezius muscle hyperplasia is caused, the winding
assembly winds and unwinds the traction rope according to the height of the handle, the winding assembly winds or unwinds the traction rope according to the adjusting position of the handle, and then the situation that the
training effect of the user is affected due to the fact that the traction rope is too loose or too tight is prevented.
