Hormones, Outcomes, and Pain Pathways in Exercise Study

This study is looking at how different sports bras affect pain in full-busted women. Researchers want to see if wearing a specific sports bra (either the Bounceless bra or Shefit Ultimate bra) for three months can help reduce neck, shoulder, arm, and back pain. They are also investigating how hormones and inflammation might play a role in this type of pain. You may be able to join if you are a woman between 18 and 60 years old, right-handed, and wear a bra band size between 32-40 inches. The study aims to enroll 140 participants.

Study design
This is an interventional study involving 140 women. It is not specified if the study is randomized or blinded.
What's involved
You would participate in one online testing session and up to four in-person testing sessions. You will use a provided sports bra for 3 months.
Compensation
Not stated in the trial record.
Follow-up
Your pain levels and physical activity will be measured at the beginning of the study and again 3 months later.
