Movement-reactive athletic apparel and methods of making the same

A method of manufacturing an article of sportswear, comprising:

• collecting kinematic data of an individual engaged in a physical activity;
• processing the kinematic data to determine a relative level of motion of at least one body part of the individual versus an anchor point on the individual;
• determining a corresponding level of support needed for the at least one body part based on the level of motion;
• dispersing particles in a fluid medium to form a suspension, wherein the suspension comprises a shear thickening fluid;
• diluting the formed suspension with a diluent to form a diluted shear thickening fluid;
• selectively treating a fabric with the diluted shear thickening fluid, wherein an area of the fabric corresponding to the at least one body part is treated based on the previously determined level of support required;
• removing the diluent from the fabric treated with the diluted shear thickening fluid such that the particles in the shear thickening fluid adhere to the fabric;
• and
• forming the athletic garment with the fabric.
