The more the biceps stretched during the first tough workout, the more strength the person lost the next day.

Reduced muscle lengthening during eccentric contractions as a mechanism underpinning the repeated-bout effect.

Randomized Controlled Trial

Human

2015 May 15

The study saw that muscles stretched more during the first workout and got more sore and weaker afterward, but it never checked if the amount of stretching directly linked to how much strength was lost — so we can't say for sure they're connected.

Similar Assertions

When people who don't normally lift weights do a tough arm exercise twice, four weeks apart, their biceps don't stretch as much the second time, even though they're trying just as hard.

The first time you stretch your biceps in each workout, it stretches the same amount—even if the second workout causes less damage overall.

80%

The more the biceps stretched during the first workout, the more 'swelling' showed up on the ultrasound scan afterward.

Your bicep works best at different elbow angles depending on whether your palm is up, down, or straight — it’s strongest at 45° if your palm is down, and 60° if it’s up.

77%

How stiff your bicep feels when you bend your elbow depends on both how bent your elbow is and which way your palm is facing — but how hard your brain tells your bicep to work doesn’t change as much with that combination.
