Activity classification based on oxygen uptake

A system of analyzing activity comprising:

• a memory;
• and
• a processor communicably coupled to the memory, the processor to:
• obtain activity data for an activity of a user, the activity data corresponding to multiple parameters;
• retrieve a set of threshold criteria that corresponds to a multi-parameter activity zone, wherein the set of threshold criteria comprises a threshold criteria related to at least one of heart rate, steps, speed, or power of the user and based on oxygen uptake;
• determine an effort of the user based on the activity data;
• determine a resistance experienced by the user, wherein the resistance comprises a measure representing at least one of stride rate, stroke rate, step rate, steps, cadence, or terrain;
• and
• classify, based on the set of threshold criteria corresponding to the multi-parameter activity zone, an instance of the activity as an activity type based on the resistance experienced by the user and the effort of the user.

A non-transitory computer readable media storing instructions which, when executed, cause a processor to perform operations comprising:

• obtaining activity data for an activity of a user, the activity data corresponding to multiple parameters;
• retrieving a set of threshold criteria that corresponds to a multi-parameter activity zone, wherein the set of threshold criteria comprises a threshold criteria related to at least one of heart rate, steps, speed, or power of the user and based on oxygen uptake;
• determining an effort of the user based on the activity data;
• determining a resistance experienced by the user, wherein the resistance comprises a measure representing at least one of stride rate, stroke rate, step rate, steps, cadence, or terrain;
• and
• classifying, based on the set of threshold criteria corresponding to the multi-parameter activity zone, an instance of the activity as an activity type based on the resistance experienced by the user and the effort of the user.
