The invention discloses a tennis racket for training. The tennis racket for training comprises a racket head, tennis strings, a racket handle, a sweatband detachably wound around the outer surface of the racket handle, a humidity sensor arranged on the racket handle to measure the humidity of the sweatband and output humidity value signals, a controller receiving the humidity value signals of the humidity sensor, and an alarm which is in electric connection or communication with the controller. The alarm is triggered by the controller when the humidity value reaches a set threshold value. The tennis racket for training further comprises multiple infrared units, an AHRS sensor, and an installation device comprising a storage cavity, a quakeproof mechanism, a probe tube and multiple damp-proof tubes. The tennis racket for training has the advantages that the stance, the number of strokes, hitting frequency, and sweatband overwetting reminding can be monitored in real time, so that a user can learn training intensity and self defects in hitting; and the electrical elements are fixed in reasonable positions and do not affect the hand feeling of the tennis racket, steadiness and reliable fixation can be ensured under high-intensive impact, and the electrical elements can stay dry in a high-humidity environment.
