  • 1. GENERAL OUTLINE OLD SKOOL STRENGTH TRAINING FOR • Background • Endurance athletes don’t need to strength train. MULTI-SPORT ATHLETES • Research • Strength training needs to be muscular endurance. • Rationale • TechniquesW.

Immediate System • ~ 5% of a distance race is anaerobic. (Green & Patla, 1992; Hauswirth & Lehénaff, 2001) Exercise Intensity • Little specific research to Glycolytic System indicate that it will improve • Reduce the incidence of overuse injuries? race performance or decrease injury potential. • More bang for your buck!

PERFORMANCE PREDICTIONS PREDICTIONS • Improved 3K run time (16:30→14:45; • vVO 2max is a better predictor of 10K and • Relative leg strength index (RLS) and jump 10:17→10:07) (Kelly et al., 2008; Spurrs et al., 2003) 90K race performance in elite runners. height correlated with average speed during (Noakes et al., 1990) 5K run. • Improved 5K run time (18:24→17:45) (Paavolainen et al., 1999a) • vVO 2max and vLT significantly correlated (Yamauchi et al., 2010) • Improved cycle TTE @ 80% VO 2max with 3K run times. (Slattery et al., 2006) • Sprint and jump performance were strongly correlated with 5K and 10K run (71→85 min) (Hickson et al., 1988) • 82% of 3K time explained by vVO2max performances. • Improved PO for 40-min cycle TT (~30 W) • 94% of 3K time explained by vVO2max + vLT (Paavolainen et al., 1999b, 1999c) • Likely that these findings can be (Rønnestad et al., 2010) • Improved PO for 5-min cycle sprint after extrapolated to cycling (March et al., 2011) 180-min ride (~30 W) (Rønnestad et al., 2011) 10 11 12WHY DOES S & P WORK?
