Running Apparel and Performance
Running Apparel and Its Effects on Performance
Running performance is influenced not only by physiological and biomechanical factors, but also by external variables such as environmental conditions and clothing. Running apparel can affect thermoregulation, comfort, movement efficiency and in some cases, metabolic cost. Although clothing does not directly enhance physiological capacity, inappropriate apparel may negatively affect performance, particularly during prolonged or high-intensity running.
One of the primary roles of running apparel is thermoregulation. During exercise, a large proportion of metabolic energy is converted into heat and the ability to dissipate this heat is critical for maintaining performance. Clothing that limits heat loss or sweat evaporation can accelerate the rise in core body temperature, leading to earlier fatigue and reduced running speed (González-Alonso et al., 2008). Lightweight, breathable fabrics enhance evaporative cooling and help maintain thermal balance, especially in hot environments.
Garment weight is another factor that may influence running performance. Even small increases in carried mass can elevate the energetic cost of running, particularly when weight is added to distal segments such as the feet (Frederick, 1984). For this reason, minimalist and lightweight apparel is generally preferred in competitive settings, where marginal gains may be decisive.
Compression garments have gained popularity among endurance runners, with claims of improved performance and recovery. Current evidence suggests that compression clothing does not consistently improve endurance performance directly; however, it may provide small benefits by reducing muscle oscillation, improving proprioception, and enhancing venous return (Born et al., 2013). Some studies also indicate potential improvements in perceived comfort and post-exercise recovery, which may indirectly support training quality (Hill et al., 2014).
Aerodynamic properties of apparel may also influence performance, particularly at higher running velocities. While aerodynamics play a smaller role in running compared to cycling, drag reduction through tight-fitting clothing may contribute to marginal performance benefits during sprint finishes or elite-level competition (Pugh, 1971).
Practical Applications
From a practical standpoint, running apparel should prioritize thermal comfort, freedom of movement, and minimal added mass. In hot conditions, lightweight and moisture-wicking fabrics are essential, while in colder environments, layering strategies should allow heat retention without excessive insulation. Compression garments may be used based on individual preference, particularly during recovery phases, rather than as a primary performance-enhancing tool.
