A wireless positioning apparatus is disclosed, which includes at least one first device and at least one second device. Each first device is disposed on each moving object and is configured to transmit a wireless signal. Each second device is disposed on a fixed position and is configured to detect a strength of the wireless signal of each first device. The wireless positioning apparatus further includes a data processor, which is configured to receive the strength of the wireless signal of each first device detected by each second device, to calculate a distance between each first device and each second device, and to ultimately determine a position of each first device to thereby realize the positioning of each moving object. A wireless positioning method and a sports training apparatus comprising the wireless positioning apparatus are also provided in the disclosure.
