This study was about how heat shock proteins, HSP70 and HSP90 change in the body after a really tough workout and over the next hour in top weightlifters. Heat shock proteins like HSP70 and HSP90 help us figure out how the body deals with stress from exercise.

We worked with 12 weightlifters from Amanat Baghdad Sports Club. They did a resistance workout that included the snatch and clean & jerk exercises at 85–90% of their maximum lift.

We took blood from these weightlifters at four times: before they started the workout right after they finished 30 minutes later and 60 minutes later.

We used a test called ELISA to check the levels of HSP70 and HSP90 in their blood.

The results showed that the levels of HSP70 went up a lot right after the weightlifters finished exercising and stayed high for a while. Heat shock proteins like HSP70 were still high in their blood, after some time. They went from 1.92 ± 0.38 ng/mL before exercise to 2.64 ± 0.45 ng/mL after and peaked at 30 minutes (2.98 ± 0.50 ng/mL) before going down a bit at 60 minutes. HSP90 levels did something. They went up from 2.73 ± 0.47 ng/mL before exercise to 3.35 ± 0.52 ng/mL after peaked at 30 minutes (3.68 ± 0.56 ng/mL) and then went down a bit.

These findings tell us that a single tough workout makes heat shock proteins, like heat shock proteins go up fast in weightlifters.

This increase in heat shock proteins happens after you do your exercise and it peaks within thirty minutes. Then it goes down over the next sixty minutes.

This shows that your body is turning on things to help with stress from exercise like the stress from a workout.

The results also suggest that HSP70 and HSP90 could be things to look at to track how stress your body is, under and to manage your workout loads in people who do strength training like strength athletes who do strength training.
