The invention relates to a gyroscopic exercise ball (10) comprising: a housing (10a, 10b) surrounding a rotor (12) centrally disposed on a shaft (14) having two ends (28) mounted in notches (26) of a freely rotatable gimbal ring (24), wherein said ring and the ends of said shaft are disposed in a groove having a height larger than a diameter of the ends of the shaft, said diameter being larger than a thickness of the gimbal ring, at least a rotation rate sensor (60) for measuring the rotor speed, a processor (110) in communication with said rotation rate sensor, said processor being configured to calculate an exercise evaluation, said gyroscopic exercise ball being characterised in that it further comprises at least one of a pitch axis and a roll axis gyroscopic sensors (80, 70) in communication with said processor, and that the exercise evaluation comprises at least one of an energy expenditure, a force, a power, angles or angular velocity of motion, a range of motion, position, speed or trajectory of motion, and an evaluation of form for an individual exercise. |
