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)
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.

The invention claimed is: 1. A training harness for exercising an athlete's inspiratory muscles, said harness being adapted when in use during the performance of aerobic exercise to embrace the athlete's thorax, said harness comprising: a chest plate, a back plate, and linkages comprising a plurality of ribs extending from each side of the back plate forwardly around each side of the athlete's thorax, to interconnect said plates, said linkages normally defining a pre-determined circumference of said harness, but permitting an increase in said circumference against an applied resistive load upon expansion of the athlete's thorax. 2. The training harness as claimed in claim 1, wherein each rib has a substantially-inextensible cord associated therewith, said cord passing through and emerging from an aperture in the chest plate. 3. The training harness as claimed in claim 2, wherein the ribs are arranged in opposed pairs, the respective members of the pair being arranged symmetrically on opposite sides of the athlete's thorax, and the distal ends of the opposed ribs in each pair are connected to opposite ends of the same cord. 4. The training harness as claimed in claim 3, further comprising at least one pair of opposed ribs adapted to embrace the athlete's shoulders. 5. The training harness as claimed in claim 3, comprising five pairs of opposed ribs. 6. The training harness as claimed in claim 2, further comprising control means including a reel device for winding-in and winding-out the cord, so as to vary the normal circumference of the harness, and thereby to vary the resistance against expansion of the athlete's thorax. 7. The training harness as claimed in claim 6, wherein the control means further comprises a dial, the rotation of which increases and decreases the length of the cord(s), and hence the resistive load imparted by the ribs. 8. The training harness as claimed in claim 6, wherein the control means further comprises a ratcheted drum including a quick release mechanism. 9. The training harness as claimed in claim 6, wherein the control means further comprises means for varying the applied resistive load during expansion of the athlete's thorax. 10. The training harness as claimed in claim 9, wherein the load varying means comprises a cam pulley adapted to decrease the applied resistive load during expansion of the athlete's thorax. 11. The training harness as claimed in claim 10, wherein the load varying means further comprises a return spring mechanism for re-setting the cam pulley following each expansion of the athlete's thorax. 12. The training harness as claimed in claim 1, wherein the applied resistive load is an elastic resistive load. 13. The training harness as claimed in claim 1, wherein the chest plate is relatively inflexible and the linkages are elastically-expandable. 14. The training harness as claimed in claim 1, wherein the applied resistive load is a frictional resistive load. 15. The training harness as claimed in claim 14, further comprising control means including a first fixed disc and a second rotatable disc in communication with one or more substantially-inextensible cords attached to the harness linkages, said first and second discs being mounted co-axially and arranged such that a face of said second disc bears against a face of said first disc, work being required by the athlete to overcome the frictional resistance between the two opposed disc faces. 16. The training harness as claimed in claim 15, wherein the second disc is capable of rotation in one direction only, such that no rotation thereof occurs upon contraction of the athlete's thorax. 17. The training harness as claimed in claim 14, wherein the harness linkages are substantially inelastic. 18. The training harness as claimed in claim 1, having a garment attached thereto, said garment formed from a compression material. 19. The training harness as claimed in claim 1, wherein the chest plate, the back plate and the side linkages are each constructed from a compression material. 20. The training harness as claimed in claim 19, wherein the chest plate, the back plate and the side linkages define a plurality of panels, each said panel being formed of a material selected to apply a pre-determined load to a corresponding area of the athlete's thorax, said load being calculated according to the degree of expansion of said thoracic area and the tensile properties of the material fibres.
