Every material pole vaulters have ever trusted has been replaced by something that bends better. Modern poles are fiberglass and carbon fiber composite, built by wrapping resin-soaked fibers around a mandrel, and that construction is why a pole can flex nearly 90 degrees and snap back without failing. It was not always this way. Bamboo carried the event through the early 1900s, steel and aluminum took over for a few brief decades, and fiberglass finally arrived in the early 1960s and never left. Each material change did not just change equipment; it reset the record book, because a pole that bends and returns energy lets an athlete convert far more of their running speed into height. The jump in records after each material shift is bigger than almost any single training innovation in the sport's history.
Solid bamboo dominated before World War II. It was light but essentially rigid, so vaulters used a reach technique with almost no pole bend, which capped clearances around 4.40-4.60 m (14-15 ft) no matter how fast the approach. Technique in this era was closer to a running high jump with a stick for balance than to the swing-and-fly motion of a modern vault, and coaching focused almost entirely on the takeoff rather than any pole-bend phase.
Hollow metal poles were more durable than bamboo but still added little useful flex. Cornelius Warmerdam famously cleared 4.77 m (15 ft 7.75 in) on a bamboo pole in 1942, and that mark stood for roughly 15 years before metal poles finally pushed past it, a reminder that the athlete, not just the equipment, still mattered enormously in this era. Metal poles were heavier than bamboo, which limited how fast a vaulter could carry one down the runway.
Fiberglass poles appeared in the late 1950s and became legal internationally by the early 1960s, phasing out metal and bamboo within a decade. Modern poles layer carbon fiber into the fiberglass for controlled stiffness, and the record has climbed from about 5.00 m in the early 1960s to 6.31 m in 2026 as the composite technology matured alongside faster approach speeds and better coaching of the swing-up phase. No new base material has displaced fiberglass-carbon composite since, though manufacturers keep refining the layup, adjusting fiber orientation and resin ratios to tune how quickly a given pole recoils after it bends.
Fiberglass-carbon composite poles store and release elastic energy at far higher efficiency than metal. The energy returned at takeoff is what carries vaulters from 5 m to 6 m+. AI form check measures how efficiently you transfer approach velocity into the pole.

Each material era is paired with the approximate world record height it capped out at, showing how directly the equipment shaped the sport.
| Era | Material | Approx. dates | Era-ending record height |
|---|---|---|---|
| Early era | Solid bamboo | 1800s - 1940s | ~4.77 m (15'7.75", Warmerdam, 1942) |
| Metal era | Steel and aluminum | 1940s - late 1950s | ~4.80 m |
| Transition | Early fiberglass (not yet legal internationally) | Late 1950s | ~4.50-4.80 m |
| Fiberglass era begins | Fiberglass composite, legalized | Early - late 1960s | ~5.20 m by decade's end |
| Bubka era | Fiberglass with reinforced layup | 1980s - 1994 | 6.14 m (Bubka, 1994) |
| Modern composite | Fiberglass plus carbon fiber reinforcement | 1990s - 2020 | 6.18-6.21 m range |
| Duplantis era | Advanced carbon-fiberglass composite | 2020 - present | 6.31 m (2026, current WR) |
