Both have their places. The mass you can lift is generally greater in HBDLs, so you could run them during a strength/power block and really load up the bar. Likewise, if you're recovering from a back injury, the decreased load on the spine during HBDLs is a definite plus. You'll still want to use both, though, for (monotonous) over training reasons as well as SBDLs' ability to reinforce proper technique. Not to mention, the majority of your contests involve SBDLs, not HBDLs.As an aside, it irritates me to no end how this study is misinterpreted. My biggest beef is the subject pool. Yes, power lifters are a far step above the normal subjects, but they compared the results to much lower-trained subject pools (see my prior post on this on the article a few weeks back). If they wanted to compare the results to a matched subject pool, they should have chosen competitive Olympic lifters. Or if they wanted to look at it for the layman, they should have trained a group of subjects for a period of time in both lifts before having them perform both in a comparative analysis, because when it comes down to it, comparing competitive power lifters to DIII athletes is apples and oranges.
