Determinants of performance
- Vo2 Max - maximum oxygen uptake (Engine Size - how big is the engine?) This is the ability of the circulatory system to transport oxygen and of the muscular system to extract and use oxygen. Vo2 max is an excellent indicator of aerobic fitness, but a poor predictor of performance within a homogenous group of athletes.
- Lactate Threshold - (RPM's - how high can you race the engine?) Lactate threshold (LT) is the ability to continue using the aerobic system to replenish ATP at high speeds. It is expressed as power output at LT, velocity of LT or percentage of Vo2 max. LT is one of the best predictors of endurance performance.
- Economy - (MPG - how many miles per gallon does your engine get?) Economy can be defined as the amount of oxygen that it takes for an individual athlete to go a given speed. More economical athletes will have a lower oxygen cost at a given pace relative to a less economical athlete. This can explain why an athlete with a lower VO2 max can still outperform an athlete with a higher VO2 max. Economy is one of the best predictors of endurance performance.
- Strength. Strength is defined as the maximum force that can be produced in one all out effort. Muscular endurance is related to being able to maintain a submaximal force repeatedly

UNMATCHED COMFORT
Our latest invention, two interchangeable and washable micropourous padding, with and without a protective net let you manage the flow through ventilation based on your preferences and environmental conditions.
ADVANCED SAFETY
The IN-MOLD technology is used to inject Styrofoam into the mold containing the cap in polycarbonate at a very high pressure. This forms a seamless rigid structure more impact resistant and lighter than any other helmet produced.
ADUSTABLE FIT
The latest development in Rudy Project technology: a toothed disc with reinforced runners, special protective wings and a rear panel with diagonal holes for fixing straps. Precise micrometric regulation and height adjustment provide a perfect, personal fit and excellent stability.
VENT TECHNOLOGY Thanks to the scientific positioning of the external air openings and the unique air channel designs carved inside the hard shell, our helmets are extremely ventilated and very comfortable to wear.

The National Cross Country Ski Education Foundation (NCCSEF) promotes the development of U. S. cross-country ski racing through its support of activities that challenge and enable athletes to achieve higher competitive goals and of efforts that will lead to success in international competitions.
The not for profit organization NCCSEF is celebrating 12 years of supporting U.S. skiing. We have granted over $175,000 in NCCSEF Future Funds over this period. In fact, we've funded every World Junior Championship team since 1997 and every J1 Scando Cup team since it was initiated in 1999. Now, as we gear up for skiing beyond 2010 there is much more work to be done and your help is needed! Find out how you can help at
