1. A motion analysis device comprising:
- a first detection section adapted to detect a first state of a shaft portion of sporting equipment using an output of an inertial sensor; and
a second detection section adapted to detect a second state of the shaft portion of the sporting equipment using the output of the inertial sensor to detect a relative rotational angle of the shaft portion having varied around an axis of the shaft portion from the first state.

Abstract
In a motion analysis device, a first detection section detects a first state of a shaft portion of sporting equipment using an output of an inertial sensor. The first state corresponds to, for example, a resting state. A second detection section detects a second state of the shaft portion of the sporting equipment using the output of the inertial sensor. The second state corresponds to, for example, an impact. The second detection section detects a relative rotational angle of the shaft portion having varied around an axis of the shaft portion from the first state.
