What You Need to Know to Participate

Introduction: You are being invited to participate in a research study to evaluate the effects of contrast therapy (alternating hot and cold treatments) on physical recovery and overall well-being. Before agreeing to participate, it is important that you understand the purpose of the study, what is involved, and any potential risks or benefits. Please take time to read this form carefully and ask any questions you may have.

Purpose of the Study: The goal of this study is to assess the impact of contrast therapy on muscle recovery, inflammation, and participant-reported well-being. Your participation will help researchers understand the potential therapeutic benefits and inform future clinical applications.

Procedures: If you agree to participate, you will be asked to complete the following:

1. Attend [number] sessions of contrast therapy at [location]. Each session will involve alternating hot and cold treatments, lasting approximately [duration].
2. Complete questionnaires about your physical recovery, pain levels, and overall well-being before and after each session.
3. Allow researchers to collect non-invasive measurements such as heart rate, skin temperature, and muscle stiffness.

Voluntary Participation: Your participation is entirely voluntary. You may refuse to participate or withdraw from the study at any time without penalty or loss of benefits to which you are otherwise entitled.

Risks and Discomforts: The risks associated with contrast therapy are minimal but may include:

• Temporary discomfort due to exposure to heat or cold.
• Rare risk of skin irritation or mild burns if sensitivity to temperature changes is high.
• Dizziness or lightheadedness during or after the session.

Benefits: You may experience improved muscle recovery, reduced soreness, and enhanced relaxation from the contrast therapy sessions. While there are no guaranteed benefits, your participation will contribute to a better understanding of contrast therapy’s effects.

Confidentiality: All information collected during the study will be kept confidential and used only for research purposes. Your data will be de-identified, and only the research team will have access to it. Results may be published, but no identifying information will be included.

Compensation: You will receive [compensation details, e.g., gift card, reimbursement for travel expenses] for your participation.

Alternatives to Participation: Participation is not required. You may choose not to participate or to withdraw at any time.
