A compression shirt is a specialized athletic garment engineered to apply gentle, consistent pressure across the torso and arms. The primary mechanical purpose of this pressure is to stabilize muscle groups, reducing unnecessary movement or oscillation during intense physical activity. This stabilization helps conserve energy and potentially reduce overall muscle fatigue. The pressure also works physiologically to promote better blood flow, enhancing the delivery of oxygen and nutrients to the working muscles.
Selecting the Right Fit
The effectiveness of a compression shirt is directly dependent on achieving the proper fit, which involves a balance between applying pressure and maintaining comfort. You should always consult the specific manufacturer’s sizing chart, as sizing standards can vary significantly between brands. For compression shirts, the most important measurement is typically the circumference of your chest, measured at the fullest part.
The shirt should feel snug and secure, creating a “second skin” feeling that lies flat against your body without any fabric bunching or wrinkling. The pressure needs to be evenly distributed, and while it must be tight enough to provide the intended physiological benefits, it should not be restrictive. If the shirt causes discomfort, hinders your ability to breathe deeply, or limits your full range of motion, it is too small. If you are between sizes, a general guideline for maximizing compression benefits is to select the smaller size, but if you are new to compression wear, opting for the larger size may initially be more comfortable.
Step-by-Step Guide to Wearing the Shirt
Putting on a compression shirt requires a specific technique due to its inherent tightness, which helps prevent stretching the material or causing discomfort. Instead of pulling it on like a regular t-shirt, it is often easier to first roll the shirt up from the bottom hem until it resembles a thick band of fabric. This rolled garment should then be pulled up over your feet and legs, similar to how one might put on a pair of tights, until it reaches your waist.
Once the shirt is at your waist, you can carefully slip your arms through the armholes one at a time, and then pull the rolled fabric up over your torso and shoulders. This method minimizes the stress placed on the seams and fabric. After the shirt is fully on, smooth out any wrinkles or folds, especially across the chest and back. Ensuring the fabric lies flat guarantees uniform pressure distribution, which is necessary for the compression technology to work effectively.
Optimal Timing and Duration of Use
Compression shirts can be worn to support the body during two distinct phases: performance and recovery. When worn during exercise, the garment’s stabilizing effect on the muscles helps to reduce the oscillation that occurs with high-impact movements, such as running or jumping. This reduction in muscle movement is thought to help decrease the perception of post-exercise soreness.
For recovery purposes, the shirt should ideally be applied within the first few hours following a strenuous workout, with benefits commonly reported when worn for 12 to 24 hours afterward. The increased blood circulation facilitated by the garment is intended to help speed up the removal of metabolic waste products, which may reduce swelling and enhance muscle repair. It is generally recommended to avoid wearing compression shirts while sleeping unless specifically directed by a healthcare professional.
