How is strength determined

Jenkins also tested his hypothesis another way, asking participants from both groups to kick out at percent intervals of their baseline strength -- from 10 percent all the way up to percent -- after three and six weeks. If high-load training does improve muscle efficiency better than low-load training, he reasoned, then high-load lifters should also use a smaller proportion of their strength -- that is, exhibit lower voluntary activation -- when lifting the same relative weight.

That's what the data generally showed. Voluntary activation in the low-load group did decrease slightly, from an average of about 56 percent at baseline to But it decreased more in the high-load group, dropping from about 57 to Placing electrodes on the participants to record the electrical signatures of their quadriceps reinforced those results.

High-load training led to a substantially larger drop in electrical activity after six weeks, the study reported, and that activity was lower across most levels of exertion. Jenkins maintained that low-load training remains a viable option for those looking to simply build mass or avoid putting extreme stress on joints, a priority for older adults and people rehabbing from injury.

Still, he said, the new study lends even greater credence to the notion that when it comes to building strength -- especially amid a busy schedule -- heavier is better. We're seeing greater strength adaptations. And now we're seeing greater neural adaptations. Jenkins detailed his findings in the journal Frontiers in Physiology. He authored the paper with former doctoral adviser Joel Cramer, associate professor of nutrition and health sciences; Terry Housh, professor of nutrition and health sciences; Nebraska doctoral students Amelia Miramonti, Ethan Hill, Cory Smith; and doctoral graduate Kristen Cochrane-Snyman, now at California State Polytechnic University.

The values of the load you used and the number of repetitions you counted the RTF are entered into a prediction equation that calculates an estimate of your 1RM. This means the person should just be able to lift 65 kg and no more.

It also means they would need a rest of several minutes before they could lift the same weight again. Add to collection. How do you go about finding just how strong you are in a particular exercise?
