Quick questions on Technology in sport: performance, monitoring, ethics: HSC PDHPE Improving Performance

Who has access? Can a club use medical and biomarker data to inform contract decisions or selection decisions in ways the athlete did not authorise?

The most-discussed recent example. Carbon-plated marathon shoes (introduced by Nike with the Vaporfly in 2017 and now produced by every major running brand) have driven measurable performance improvements at all levels. The mechanism is a carbon plate that stores and releases energy in a way that improves running economy by 3-5%.

The 2008-2009 polyurethane and neoprene swimsuit era produced dozens of world records in a 24-month window. FINA banned these suits in 2010, returning to textile-only swimwear. The episode is the canonical example of a technological advance forcing rule changes.

Aerodynamic frames, time-trial bikes, disc wheels, deep-section wheels, aerodynamic positioning, and integrated cockpit designs have transformed cycling. The UCI imposes minimum bike weights and other restrictions to prevent technology from making the sport effectively unfair.

Tennis rackets, golf clubs, cricket bats, hockey sticks, surfboards - every piece of sporting equipment has been engineered over the last decades. The rules typically constrain dimensions and materials to keep the technology within the spirit of the sport.

Whole-body cold exposure at temperatures of -100 to -140°C for 2-3 minutes. Widely used in elite sport for recovery. Evidence of benefit beyond the placebo effect is mixed but the practice is widespread.

Pneumatic compression boots (NormaTec and similar) apply progressive compression to legs. Athletes use them post-training and post-competition. Evidence supports reduced perceived soreness; objective performance benefits are smaller.

Simulated altitude for "live high, train low" adaptation. Used by endurance athletes to boost red blood cell mass. Some sports have restrictions; most allow it.

Mattresses, sleep tracking, light management, temperature management. Sleep is increasingly recognised as the single most important recovery factor, and athletes invest substantially in protecting it.

Dedicated recovery facilities at AIS, state institutes of sport, and major club training centres. Combine multiple modalities (pools, cryotherapy, massage, nutrition support, sleep monitoring).

Used in field sport (AFL, NRL, rugby, soccer, hockey). Track distance covered, speed, sprint distance, acceleration, deceleration. Data drives training load decisions and helps identify athletes at risk of injury.

From chest straps to wrist-based optical sensors. Tracks training intensity (relative to estimated max), recovery (HRV), and acute physiological stress.

In cycling and rowing. Measure direct power output rather than relying on heart rate as a proxy. Allow precise training prescription.

Blood testing for ferritin, vitamin D, cortisol, testosterone, immune markers, and inflammation. Elite athletes have substantial blood work routinely; recreational athletes have less.

Wearable devices and bed-based tracking. Sleep duration, sleep stages, heart rate variability.
