FIELD: training equipment. SUBSTANCE: running track has base 1 with supports 2, driving and driven members 3, endless belt 4 adapted for embracing driving and driven members 3, parallel racks 5, supporting platform 6 mounted on base 1 above driven member and endless belt 4, and antifriction surfaces 7 disposed on base 1 and racks 5. Each rack 5 is embraced by side endless belt 8 positioned outside base support. Such construction allows width of training platform to be increased and arrangement of supports beyond sides of apparatus to be excluded. EFFECT: increased efficiency, improved training safety, increased convenience by reduced weight and improved design parameters. 2 dwgw |
