GENERAL OUTLINE OLD SKOOL STRENGTH TRAINING FOR • Background • Endurance athletes don’t need to strength train.

(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?
