Mountaineering Training | Anaerobic Threshold & Interval Training
Categories: Mountaineering Fitness & Training
Mountaineering is thought of as a “slow and steady” sport. Indeed, the climbing pace when nearing the summit is amazingly slow given the effort required by the high altitude, especially in comparison to moving at the same speed at lower elevations. As a result, climbers often overlook the necessity of incorporating speed and intensity into their training routine and instead focus on long, slow aerobic-oriented workouts. This is a mistake. Interval training is an important component of conditioning for mountaineering as it raises your anaerobic threshold, effectively giving you “more gears” when climbing at altitude.
Aerobic vs. Anaerobic
Generally speaking, aerobic activity is the zone of physical activity where the body is able to provide adequate oxygen to the cells to keep them fueled, reducing the rate of fatigue. Anaerobic exercise is when the physical effort is high enough that the body cannot provide enough oxygen to the cells, causing them to use other energy stores to make up the difference and causing a much higher rate of fatigue. Think of taking a casual walk through the park (aerobic) vs. sprinting up multiple flights of stairs (anaerobic) - which can you sustain for longer?
As athletes and climbers, our goal is to raise our anaerobic threshold - the level of effort where our bodies transition between aerobic and anaerobic activity. A higher anaerobic threshold allows us to climb at increased effort levels (like climbing at altitude) without entering an anaerobic zone and tiring quickly. Some sources say that climbing in your anaerobic zone will deplete your energy stores as much as 16x more quickly than staying within your aerobic zone! Raising your anaerobic threshold provides huge gains to your fitness when you head into the mountains.
Interval Training: Raising Your Anaerobic Threshold
Interval Training is one of the most effective way to raise your anaerobic threshold. Interval training consists of short, intense bursts of physical effort. Learn more about general interval training here. The best types of intervals for improving your anaerobic threshold are extended efforts at just below your maximal effort level (or maximum heart rate if you train with a heart rate monitor) repeated several times with an equal amount of rest between intervals. The exact intervals you complete depends on your fitness level and chosen activity. Discuss an appropriate interval plan with a trainer or fitness specialist. General intervals targeting your anaerobic threshold include:
• 4 x 4 mins with 4 mins rest
• 5 x 3 mins with 3 mins rest
• 4 x 800m with 3 mins rest
You can do intervals while running, hiking, biking, on a rowing machine, or any sort of aerobic exercise equipment. Be sure to properly warm up and cool down before and after every session. Like all training activities, anaerobic interval training is best incorporated into a broader training routine, be sure to continue to include aerobic, strength and core, flexibility, and balance and agility training. It is best to begin your interval training in the early stages of your training plan so that your body is familiar with the exercises, you have the time to recover and improve, and are not exhausting yourself with intense interval training immediately before your climb.
In order to truly go “slow and steady” in the mountains, we need to first go short and fast!
