The functional assessment of aerobic endurance is very expensive, time consuming and needs to be done in specialized laboratories
The evaluation is carried out by means of stress testing and parameters such as heart rate, electrocardiogram or maximal oxygen consumption (VO2max) have been measured
There are not any solutions yet, based on mobile applications allowing people to perform this assessment by themselves

Materials and Methods
Goal-Oriented Design Methodology
The G-OD follows the trend of giving more importance to the user in the process of designing and developing interactive products
It revolves around three fundamental aspects o The characters ‘Persona’ concept
o The scenarios: What should this product do? How should this product come up and behave?
o The goals: are driving forces behind the behaviour obtained from the user

Materials and Methods
AttrakDiff Questionnaire
Based on a model by Hassenzahl and others Takes into account pragmatic and hedonic
aspects o Pragmatic aspects: quality and usability
o Hedonic aspects: autonomy, security, competition or relationships with others

Functional Assessment System (FAS)
The FAS is an AmI System developed for performing a functional assessment of aerobic endurance
Application automatically assumes many functions and is more comfortable for the user
To learn how to use the FAS almost perfectly, users do not need a very high number of attemps

User description: ‘Persona’
«My name is Laura and I am 29 years old. I practice sports regularly, about 3 times a week. For several years, I have been caring for my fitness and my diet, so I would love to have some information about my cardiovascular health at any time, in a simple, convenient and reliable way. I don´t like to go to a specialized place for a basic control of physiological parameters during exercise, because it is expensive and very time consuming.»

Conclusions
The FAS system has been validated using the AttrakDiff questionnaire
Very positive outcomes the FAS has resulted to be quite innovative, very intuitive and highly usable
The application is expected to benefit people who practice sports regularly by providing them with a tool for completing functional assessment of the aerobic endurance on their own
It helps users to exercise in a healthier and safe way
