The Landgraaf Fall Camp was held from October 12 to 17 and featured a programme filled with on and off snow activities under FIS' COVID-19 protocols.

FIS said athletes from the four nations improved their jumping skills and developed new tricks during their visit to a trampoline park.

Skateboarding, intensive physical work in the gym, a specific plyometric jump training and kickboxing were also carried out at the camp, according to the FIS.

"SnowWorld Landgraaf provides very good training conditions for the early season," said camp co-ordinator Martin Oostdijk.

"The professional park’s constant conditions give the opportunity to train on snow twice a day, with an easy lunch break in between.

"The run is not very long, but highly effective with a dedicated park lift.

"The athletes were able to do around 12 runs per hour.

"On the last day, even an evening session was on the programme."

FIS said a series of workshops saw information shared on how to plan a season, how and why physical training should be used and what a trainer can do to benefit athletes.

"Both the attending teams and the camp staff look back on a successful week where new and lasting friendships were made and enthusiasm and skills were brought to a higher level," FIS added in a statement.
