10% more powerful in 3 weeks. This is how you do it.

10% more powerful in 3 weeks. This is how you do it.

Summer is here and it's time to ramp up the fitness. 

This 3 week program is the fastest way to improve your overall fitness and aerobic capacity. 

The longest session in this program is 3hrs long and the Key Performance Indicator will be your ability to hold a hard endurance pace for up to 2hrs.

By improving your tempo endurance capabilities you will be able to complete almost any group ride or training session and kick off your summer of cycling.  

The AIRhub will be the most important tool for these sessions as it will reduce your riding speed and allow you to complete the tempo sets at a more comfortable pace. Just like when you are climbing, as the pace drops it becomes easier to produce more power for the same effort. 

Consistency is the key as each session is designed to prime the next session. No single day is more important than the next. If the mid week long ride cant be completed due to work commitments it can be split into two sessions to maintain the daily volume.

seated power session
1 Set = 40s sprint, 20s recovery x4
3 Sets of 4 min. 5min recovery between sets.
Designed to maximise seated power and maintain maximum oxygen delivery.
Slow Endurance 
Do not exceed 75% of maximum HR.
This is a tempo preparation ride.
Going too hard will destroy tomorrow's session.
Tempo
Tempo sessions should be completed at 80% max heart rate. Never exceed 85% max HR.
Don’t use power, only target heart rate as it will track with body stress. 
By the 3rd week you should see a massive increase in your tempo power and duration.

 

Tempo sessions consume a significant amount of Carbohydrates sometimes over 200g in a single session. Make sure to to consume adequate fuel during the sessions and refuel post ride. Fruit juice is the best source of carbohydrates for post tempo refueling as it contains both glucose and fructose. Fructose is important as it will recover liver glycogen much faster than a glucose recovery drink alone. 

Don't be afraid of the duration of the tempo sets during the second and 3rd weeks. These sessions are completed on heart rate. The great thing about training to heart rate is that as you get tired, your heart rate will start to drift upwards and the effort will remain constant and sometimes even reduce. This drift reflects the metabolic fatigue and is one of our training targets. 

Good luck and enjoy the improvements. 

Stress hormone IL-6 and chronic malnutrition

Are you struggling with low Iron? 
There is a fair chance that you eat a healthy balanced diet with with adequate iron levels, but your body just won’t absorb it. The below scientific review describes the way that the muscle derived stress hormone Interleukin 6 (Il-6) blocks the uptake of Iron in the gut and can lead to low serum Iron levels.

Energy balance and muscle glycogen levels can dramatically influence Il-6 levels and this stress response may lead to a chronic malabsorption of Iron and other nutrients from the foods you eat.

Correctly timing meals around training and rapidly restoring muscle glycogen after a training session is the best place to start when reversing chronic stress induced malnutrition.

Within the first 20 minute window after a training session you must consume at least 1g of simple sugars per Kg of body weight and 20g of protein to maximise energy uptake into the muscle and halt the damaging stress response.

Consuming 40g- 60g of carbohydrate drink every hour during exercise has also shown to reduce the depletion of muscle glycogen and reduce the Il-6 response during exercise.

If you have low iron levels talk to your sports doctor to have your baseline iron levels tested and begin the above nutritional interventions. Follow up with a second test 1 month later to observe the changes in your body.

Champion athletes are created from the small decisions they make each day.
Stay healthy and train smart.

Nutritional interventions and the IL-6 response to exercise
https://www.fasebj.org/doi/pdf/10.1096/fj.201700080R

“Another potential consequence of sustained elevations in IL-6 is a decline in nutrient absorption, particularly nutritionally essential minerals such as iron and zinc. Circulating levels of iron and zinc increase immediately after exercise and decline with recovery. Inflammation, particularly the release of IL-6, is known to contribute to the decline of iron and zinc (termed the hypoferremia and hypozincemia of inflammation).”

“The mechanism for the hypoferremia of inflammation is well established and involves IL-6-induced increases in the hormone Hepcidin.” (Hepcidin causes iron levels to fall due to decreased iron transport in the gut and the trapping of iron in cells.)

“Sparing muscle glycogen and maximizing recovery are essential for optimal performance during exercise and in conferring the adaptive benefits of repeated exercise bouts with recovery (i.e., training). Because IL-6 is thought to respond to the energy available to the exercising muscle, various nutritional interventions have been studied with the goal of sparing energy stores and mitigating increases in muscle-derived IL-6. In addition, nutritional interventions have sought to reduce muscle damage and the resulting IL-6 associated with tissue injury to maximize recovery and the adaptive response to exercise.”

“Nehlsen-Cannarella et al. demonstrated an attenuation in the exercise induced increase in plasma IL-6 in marathoners consuming a carbohydrate beverage compared to those consuming a placebo beverage after a 2.5-h run at 75 to 80% maximum oxygen consumption (VO2max). A similar degree of attenuation was observed in cyclists that cycled for 2.5 h at 60% maximum work rate (Wmax; 75% VO2max)”

“Consistent with these findings, Nieman et al. reported reductions in plasma IL-6 in triathletes who consumed a carbohydrate compared to a placebo beverage, regardless of whether the participants ran (55% reduction) or cycled (35% reduction) for 2.5 h at 75% VO2max. The lowest IL-6 concentration observed after exercise was in participants consuming the carbohydrate beverage and cycling, whereas the highest IL-6 concentrations occurred in the participants consuming the placebo beverage and running.”

What are the expected physiological adaptations for training in different zones?

What are the expected physiological adaptations for training in different zones? 
The photo attached is the work of Dr Andy Coggan, the Author of Training and Racing with a Power Meter and founder of the smart training movement we see today.

The table outlines the expected physiological improvement for training completed in each of the 7 zones.

We can see from this chart that training above Vo2 max does little to improve our lactate threshold or improve glycogen storage; two of the major contributors to exercise performance. 

Tempo and Threshold work deliver the biggest training adaptations and this is why they form the basis of a high performance training program.

AIRhub is the number 1 tool for generating more time in Tempo and Threshold zones and this is why it’s the choice of world class athletes. As used by Record breaking Ironmen and Athletes on 8 different World Tour cycling Teams, the AIRhub puts you into the most effective training zones at the press of a button.

The AIRhub resistance is specific to you and your training time. Most cyclist don’t have the time to ride their bike all day, that’s why smart training using the AIRhub always delivers quick results. A 40minute high resistance ride around the suburb is enough to activate all the physiological adaptations listed in the chart above. It’s possible to apply the maximal adaptation for the minimum training dose by training smart.

To read more about smart time effective training have a quick google for Andy Coggan’s work and be sure to read some of the www.AIRhub.com.au training blogs. The 2x 20minute training session and the “Sweet Spot” concept is just some of his work.
