Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of training equipment, in particular to a land training device for water sports. BACKGROUND

[0002] As a water sport carrying the folk culture and competitive spirit of thousands of years, the charm of dragon boat racing lies not only in the team cooperation of drum and song, but also in the precise control of rowing rhythm and body balance in the left and right swing formed by wave disturbance and water flow impact when the boat body cuts through the water. The explosive force output under this dynamic balance is the core feature that distinguishes dragon boat racing from other land collective projects. However, due to factors such as site conditions, weather changes and safety control of natural water areas, the daily training of professional dragon boat teams increasingly relies on land simulation equipment, among which, the existing technology announcement No. CN212235919U Dragon Boat Ergometer has become an important tool for improving athletes' physical fitness and skills by reproducing the basic rowing motion and resistance.

[0003] Currently, the mainstream dragon boat ergometer is based on a fixed platform, which can only reproduce the forward and backward force trajectory during rowing, but cannot simulate the left and right swing of the real dragon boat on the water surface caused by factors such as the difference in single blade immersion depth and water flow lateral impact, making it difficult for athletes to exercise their core stability, lateral muscle control and on-the-spot response ability to adjust the rowing angle in dynamic balance during land training.

[0004] Secondly, dragon boat is a team sport with team cooperation as its soul, and the consistency of multiple actions is crucial, but the existing ergometer is only for single-person training and cannot realize the linkage of multiple actions, making it difficult for the team to train cooperatively, which ultimately leads to a serious disconnection between training effectiveness and actual combat needs.
