Resistance Training And Running Performance And Economy: A Literature Review, James Bottrill
University Honors Theses
Running performance is largely determined by maximal oxygen uptake (VO2 max), velocity at VO2 max, fractional utilisation of VO2 max and running economy. Running economy is relatively under-researched and could be improved by resistance training because of its neuromuscular underpinnings. However, existing research on this topic is quite unorganised and inconclusive and is yet to prove a direct linkage between resistance training, running economy and performance. This literature review aimed to provide an organised overview of the existing literature, identify and address confounding variables and provide recommendations for future research. A search for studies was conducted via …
