Training Zones

To well understand Coachmyride workouts content and also cyclist training, you need first to understand training zones model which relates training intensity to your individual ability.

A training zone is defined by an upper Heart Rate Limit and a lower Heart Rate Limit.
Hear Rate (HR) is measured beats per minutes (bpm). To measure your Heart Rate, prefer using HR monitors than taking it manually (too dangerous while riding a bike). You can find HR monitors in many stores (even in some supermarkets) from affordable price; this is a must to have for serious training.

Description

The following table describes the following six-zones model uses by CoachMyRide :

Zone Purpose Perception
Recovery Regeneration and Recovery
1 Establish base endurance Riding feels like a stroll on a bike.
2 Improve efficiency No pain is felt. Fatigue sets in after 3 or 4 hours.
3 Improve sustainable power The first onset of muscular pain appears.
Breathing moderately elevated
4 Push threshold up Progressive increase in pain.
5 Sustain a high percentage of maximal aerobic power Fast increase in pain and the legs burn.
Breathing becomes extremely deep so you can only speak 4 words before gasping for breath.
6 Increase maximum power output Impossible to talk. This is painful.

Physiological adaption

The following table summarizes the purpose and physiological adaptation of each of the training zones and the benefits for cyclism :

Zone Purpose Physiological Adaptations Race fitness
Recovery Regeneration and Recovery Increase blood flow to muscles to flush out waste products and provide nutrients. Promotes recovery and therefore training response.
1 Establish base endurance Improves fat metabolism, gets muscles/tendons/ligaments/nerves used to cycling. Increases economy. More efficient use of energy. Prepares body for harder training, works on technique/skill.
2 Improve efficiency Improves the ability to use oxygen, produce power and increases efficiency. Able to produce more power with the same level of effort, works on technique/skill.
3 Improve sustainable power Improves carbohydrate metabolism, changes some fast twitch muscle to slow-twitch. Improved sustainable power, good for all cycling events.
4 Push threshold up Improves carbohydrate metabolism, develops lactate threshold, changes some fast twitch muscle to slow-twitch. Improved sustainable race pace, useful during tapering or pre-competition periods: too much time in this zone can cause staleness.
5 Sustain a high percentage of maximal aerobic power Develops cardiovascular system and VO2max, improves anaerobic energy production and speeds turnover of waste products. Improved time trialling ability and resistance to short-term fatigue.
6 Increase maximum power output

To sum up

Low Intensity
Ensure fat burning easy to ride intensity.
Medium Intensity
Carbo hydrate becomes the main fuel . Continuous conversation is difficult (breathing becomes powerful and rapid) . Upper end of zone 4 corresponds to lactate threshold (significant stress and lack of oxygen management) from this point effort is time limited and muscle pain is increasing.
High Intensity
Very uncomfortable intensity to be used by well trained competitive riders.
