The clothing has a flexible waist belt (31) that expands in a longitudinal direction and is arranged transverse to a longitudinal axis of a support in a main body. Electrodes (25-27) that derive electrical impulses of heart are arranged on an external side of the belt. Strain sensors (28, 29) are disposed within the belt. An insulating layer placed between the strain sensors and the body of the clothing absorbs the moisture from human body.
