An article in medicine and science in sports and exercise ["maximal leg-strength training improves cycling economy in previously untrained men" (2005, vol. 37, pp. 131–136)] studied cycling performance before and after 8 weeks of leg-strength training. seven previously untrained males performed leg-strength training 3 days per week for 8 weeks (with four sets of five replications at 85% of one repetition maximum). peak power during incremental cycling increased to a mean of 315 watts with a standard deviation of 16 watts. construct a 95% confidence interval for the mean peak power after training.
