<p>A training harness ( 11 ) for exercising the inspiratory muscles of an athlete ( 10 ) is adapted to embrace the thorax ( 12 ) of the athlete ( 10 ) during the performance of aerobic exercise. The harness ( 11 ) has a back plate ( 13 ), a chest plate ( 14 ) and linkages ( 15 - 24 ) interconnecting said plates ( 13,14 ) by extending around the thorax ( 12 ) of the athlete ( 10 ). The linkages ( 15 - 24 ) define a pre-determined circumference of the harness ( 11 ), which may be increased when the athlete's thorax ( 12 ) expands upon inspiration-however such an increase in the circumference of the harness ( 11 ) requires the athlete ( 10 ) to work against an applied resistive load.</p> |
