Effort classification based on activity and oxygen uptake

A method of analyzing activity comprising:

• receiving activity data pertaining to an activity being performed by a user;
• retrieving a set of threshold criteria that includes a threshold criteria related to one or more parameters associated with the activity, wherein the threshold criteria is based, at least in part, on an indirect or inferred measure of oxygen uptake;
• determining an effort of the user associated with the activity data;
• determining a resistance experienced by the user based on analytics conducted on at least a first parameter of the one or more parameters;
• and
• classifying, based on the set of threshold criteria, the activity as an activity type based on the resistance experienced by the user and the effort of the user.

A method comprising:

• receiving activity data from one or more activity monitoring devices, the activity data including at least a first monitored parameter and a second monitored parameter different from the first monitored parameter, wherein the first monitored parameter comprises a step rate, the step rate being based on a rate of motion;
• determining an effort of a user in performing the activity, the determining of the effort is based on the first monitored parameter;
• determining a resistance experienced by the user based on the second monitored parameter;
• and
• classifying the activity as an activity type based on the first monitored parameter satisfying a first threshold criterion of a set of threshold criteria and the second monitored parameter satisfying a second threshold criterion.
