The NFL’s Melbourne Game: Why a 17 Hour Time Difference Doesn’t Mean a 17 Hour Circadian Challenge
Melbourne may be 17 hours ahead of the US West Coast, but biologically, that does not necessarily mean a 17-hour shift. Because the body clock operates on a 24-hour cycle, Melbourne can also be viewed as seven hours behind. The challenge for the West Coast teams playing the NFL’s first game in Melbourne is therefore […]
Travel Performance: Why Jet Lag Is Only Part of the Story
In elite sport, travel is often treated as a logistics problem: book the flights, organise the transfers and arrive with enough time to prepare. But teams experience something more complex. Travel can affect readiness, recovery and behaviour—altering how athletes sleep, feel, think and perform before, during and after a journey. An athlete can cross several […]
2026 Nations League Championship: What Existing Research Tells Us About Travel and Performance
About 2026 Nations Championship This year’s Nations Championship marks an exciting evolution in elite international rugby, but it also presents one of the most complex travel challenges in professional sport. With matches likely across multiple continents, time zones and recovery windows, the competition will test not only skill and strategy but the physiological resilience of […]
The Australian Open: Before the Heat and Hard Courts, Comes Jet Lag
The Australian Open is often framed as a battle against heat, hard courts, and early-season fitness. But beneath the surface, it presents a different and often underestimated challenge: circadian disruption. For many players, Melbourne is the furthest stop on the calendar. Long-haul, eastward travel for most, compressed preparation windows, and unfamiliar match timings mean the […]
The Toughest Jet Lag Loads in Modern Sport – And Who Really Has it Worst
Global sport is expanding at speed. Leagues are crossing continents, fixtures are moving into new markets, and travel is now a performance variable that athletes and coaches can’t ignore. From the NFL opening its season in Brazil, to La Liga playing in the U.S., to the NBA’s expanding global circuit, elite athletes are competing further […]
The Real Cost of Jet Lag on High Performance and How to Turn It Into an Advantage
In high-performance environments, preparation is everything. Organisations analyse opponents, refine strategies, and fine-tune output down to the last millisecond. But one variable that often goes underprepared is jet lag. Picture this: you’ve just stepped off a long-haul flight and are expected to perform at your best in a completely different time zone. Your brain still […]
Why circadian alignment might be your team’s big competitive edge
When high-performance teams travel, it is possible to log nine hours of sleep and still underperform. The issue isn’t always total sleep loss or travel fatigue; it’s often when that sleep occurred relative to the state of the body clock – our circadian clock that influences alertness, coordination, decision-making, and athletic output. In travel, timing, […]
