The evolution of “Aero-Bars” (triathlon bars) in cycling represents a milestone in the “marginal gains” philosophy, focusing on the reduction of frontal area. By allowing the cyclist to tuck their elbows inward and stretch their arms forward, aero-bars minimize the “pocket” of air that hits the rider’s chest, which is the primary source of aerodynamic drag.38 This position can save a rider between 30 and 90 seconds over a 40-kilometer time trial compared to riding on standard “drop” bars. However, this posture, practiced by athletes in aerodynamic Hoodie shirts or kits, shifts the rider’s center of gravity forward and narrows their steering base, requiring a high degree of core stability and specialized “proprioceptive training” to handle the bike safely at high speeds.

The “Neurochemistry of the Runner’s High” has recently been re-evaluated, shifting the focus from endorphins to Endocannabinoids. While endorphins are too large to easily cross the blood-brain barrier, endocannabinoids like anandamide (often called the “bliss molecule”) can move freely from the blood into the brain. Anandamide levels spike after moderate-intensity aerobic exercise, binding to the same receptors targeted by THC. This chemical surge induces the characteristic state of reduced anxiety, euphoria, and increased pain tolerance. This suggests that the Hoodie shirts is an evolutionary reward system designed to keep prehistoric humans running long distances during “persistence hunting” without being sidelined by pain or exhaustion.

When a pilot or driver pulls a high-G turn, the blood is physically pushed toward the feet, potentially leading to G-LOC (G-induced Loss of Consciousness) as the brain is starved of oxygen. To combat this, athletes use Hoodie shirts that inflate to squeeze the legs and abdomen, and a specialized breathing technique called the AGSM (Anti-G Straining Maneuver). This maneuver involves tensing the leg and core muscles while performing short, sharp exhalations against a closed glottis to manually force blood back up to the heart and brain, essentially turning the body into a manual pump to withstand forces up to nine times the strength of gravity.
