The health area has been going through great changes in the last couple of years, promoted by the recent technological advancements1. There has been fast increase in health intervention through the incorporation of mobile technology, which has been adopted for the increase in healthy behaviour and better life conditions for the populations2.

The concept known as e-health refers to technologies applied to information and communication in the individual’s and the populations’ health care. One of the e-health components is the ‘mobile health’ (mHealth): this is the medicine or public health aided by the support of mobile devices, as cell phones, patient monitoring devices, digital personal assistants and other wireless devices. These are means which enable the transmission of different types of communication about health and wellness, through their applications3), (4), (5.

The increasing growth rate of the elderly population has provoked the promotion of actions and resources that contribute to this group better quality of life and health, since aging represents a natural phase in the life cycle that presents biological effects associated to the decline of physiological, sensorial, cognitive and emotional functions, which have direct reflex on the elderly’s interaction6), (7.

In 2005, the World Health Organization (WHO) broadened the concept of “healthy aging” through the creation of the Elderly Health National Policy, which promotes not only the absence of organic diseases, but mainly, autonomy, independence and functional ability conditions. Seeking quality for the attention paid to old individuals, actions, policies and programs are developed, which are structured based on procedures of care focusing on the user, taking into consideration their rights, needs, preferences and abilities8.

Therefore, it is relevant to encourage the elderly to keep a healthy lifestyle throughout aging, raising their awareness of the need to be physically active. Regular physical exercise and the adoption of an active lifestyle are means to promote their health, as a way to control non-transmittable chronic diseases that appear more frequently during aging and as a way to keep their functional independence9.

In addition, several physical aspects can be improved by the use of technology, since proper means are offered that optimize the participation of old people in continuous physical activities, becoming important aids for the elderly’s quality of life. Moreover, more and more old people have demonstrated good relationship with technology, and the technological insertion in the everyday life of this population has been observed as well10.

Bearing that in mind, this paper aims at reporting the development of the application “Idoso Ativo” (Active Aging) for mobile devices (for the operational systems IOS and ANDROID) presenting proposals of functional exercises for the lower limbs for old people.


This study belongs to the type “experiment report” on the development of a mobile platform application called “Idoso Ativo” (Active Aging).

The study was approved by the Ethics and Research Committee of the Catholic University of Brasilia (n. 879.781/2014) and the application “Idoso Ativo” (Active Aging) was developed in three phases. For the app video recording, a woman over 70 years old was selected, who signed the Informed Consent form and the Use of Image Consent Form.

The project received financial support from CNPQ pursuant to the letter MCTI/CNPq N° 14/2014.

The research was carried out at the Catholic University of Brasilia, where the research team held their meetings and the app videos were recorded.

A team of technicians was hired for the graphic components and technological development, and they created the application interfaces within the criteria put forward by the researchers.

Phase 1: Content Definition

The choice of exercises included in the application was carried out after the survey of clinical tests and the formation of a panel of experts, who were two researcher physical therapists and two students in the physical therapy undergraduate course at the Catholic University of Brasilia. The physical exercises initially selected were those that evidenced significant results in the elderly’s posture, balance and muscle strength.

After the main exercises had been selected from the survey of clinical tests, the committee discussed and chose the exercises that would be selected for videoing to be posted in the application. The exercises were divided into two phases according to the degree of difficulty and presented in four types: warm-up, strength, balance and relaxation. Table 1 presents each exercise with the description of how to do them.

Table 1 Exercises selected after survey of clinical tests

Walking is a low impact physical exercise which increases vitality. Keep shoulders and arms relaxed and a constant pace. Heart beat must be kept at a stable rhythm.

Phase 2: Sampling and video recording

Meetings were held every other week to discuss the project and organize the data.

An elderly was selected to record the video, the participant was over 70 years old, functionally independent and cognitively able to understand the exercises proposed. She signed an informed consent form and an image rights form to take part in the research.

The video recording was carried out in three sessions. The video images were produced by a professional team aided by the team of physical therapists. The whole team was concerned to present a lit environment, free of noises, with suitable lighting both for the technical effects and the safety of the participant. The audio for the exercises was recorded simultaneously with the clear description of how to perform them.

Mechanotherapy equipment was used to perform some of the exercises, such as sticks, dumbbells, steps, ball and chair. The interdisciplinary work of the professionals was important during the video recording aiming at the suitable performance of the exercises and the sound and image quality. It seems important to emphasize the need of previous training with the elderly participant for better execution of the exercises proposed, arrangement of the equipment and team synchrony.

The videos were edited by the communication team using the Adobe premier editor and after being approved by the team of physical therapists, it was sent to the programmers who were responsible for the design of the application layout.

Phase 3: Application programming

A plan was devised including how the application would be developed, the functionalities to be made available to the users, the interface to be used as well as the safety elements related to data storage and content presentation. Therefore, it was necessary to count on professionals of the information technology area to develop the application and make it available in digital media, with the purpose of designing it in an interactive and user friendly manner.

Results and discussion

The software was produced by a team of computing technicians who were experienced in the application programming area. A framework called PhoneGap was used, whose choice was based on promoting interoperability between the main mobile operational systems currently available. This implies that, for the developer, the application can be designed using a single source-code, which is processed and compiled in different programming languages, according to each mobile operational system. The devices considered mobile systems are digital personal assistant, cell phone, tablet or smart phone, characterized by their processing power, local storage, access to data transmission technology such as Wireless Fidelity (Wifi) and Bluetooth, equipped with an operational system adapted to their hardware specifications11. Also, the application was made available to mobile devices, tablet, cell phone and smart phones with free access developed for the systems IOS, Android and Windows Phone.

The window as well as the whole application layout went through a process of choice of colors, fonts, sizes and graphic design proposed by the developer, revised by the team with tests and returned for the necessary changes until the desired application was obtained.

The application shows an initial screen with presentation and objectives to be achieved, the brand of the proponent institution and the logo of the study financial support agency (Figure 1). It also presents the tutorial with instructions for the user and the way to navigate to other windows, a screen with instructions and recommendations for the performance of the exercises proposed as well as a screen with a form for the register of the elderly containing name, age, weight, height, sex and email address.

Figure 1 Initial screen with the application presentation. 

The following screens illustrate the phases (Figure 2) and their modalities, enabling the elderly to customize their training program and follow the performance of the exercises (Figure 3) with the availability of explaining videos for each exercise. Each phase was divided into four modalities which are: warm-up, strength, balance and relaxation, with three exercises each.

Figure 2 Presentation for phase selection. 

Figure 3 Presentation for the selection of modalities and exercises. 

At the beginning of each phase, a preview of the exercises that were used was added with explanations about the phase and instructions of use (Figure 4).

Figure 4 Preview with presentation of each phase. 

The application also presents a menu in the lateral tab, which makes it possible to access instructions, register change and user change, enabling the register of more than one old person in the same device.

When each modality of exercises is finished, the user is directed to reply in a window that opens the Borg scale12, from the icon “finalizei o exercício” (exercise ended), according to its perceived exertion, and the results are sent to the MySQL data base hosted in the online server REST Json available for the professional that needs to have access to this information, following the old person’s performance along the training.

The application “Idoso Ativo” (Active Aging) was officially registered by the proponent institution along with the researchers.

Technology allied to health

Physical activity developed by the elderly characterizes the adoption of an active lifestyle, indispensable to be healthy, since physical abilities are developed, which have been sometimes limited by the aging process13. Reduction in the physical activity levels appears as a risk factor related to the development and worsening of chronic diseases such as obesity, diabetes and circulatory system illnesses, with the need to implement programs promoting physical activities14.

The relation between physical activity, health, quality of life and aging seems to be evident, and has been more and more discussed and scientifically investigated. This has resulted in a consensus that physical exercise is a determining factor for the functional improvement of these individuals13. For the elderly, functional exercises are beneficial to maintain and improve their strength and muscle power, which are necessary to keep them independent in their daily life activities15. Flexibility, agility, strength, balance, aerobic resistance and psychosocial aspects provide the elderly with a holistic approach to quality of life and the elderly need this interaction both in their families and in the society as a whole16.

The proposal for the selection of exercises in the application considered aspects such as frequency, intensity, number of repetitions and also the progression for their execution, aiming at the elderly’s physical and functional performance. It is relevant to highlight that the selection of exercises must include functional exercises, suitable for increasing physical performance and that promote the improvement of strength, balance and posture, therefore, developing these individuals’ functional capability as a whole17. Another very important aspect regards suitable recommendations and instructions for the exercises proposed, so that their wrong execution or beyond the maximum capability presented by the individual is prevented. It seems also important to consider an appointment with a qualified professional that will follow the training, being aware of the elderly’s needs and possible complications, so that the training program can be safely carried out18.

The literature presents reports on the adoption of technologies as useful and interactive media able to promote health. A study developed in the United States identified software and applications related to healthy eating habits, physical activity, personal health and wellness19.

Many studies have already demonstrated that the development and use of applications have helped treatments and diagnosis, in specific cases, have broadened the health approach and become beneficial due to the prevention and control of illnesses such as diabetes4), (20. A study has also been reported using the technology developed for the control and monitoring of glucose levels in young patients with diabetes type 1, whose project included bands to measure the glucose levels and were available in mobile applications, present in iPhone or iPod Touch and a glucometer with a Bluetooth adaptor to transfer the information about the glucose levels in the blood automatically to the application20.

The approach to health has already included elderly groups in research using the technology of applications, specifically to improve cognitive capability. In a study by Hartin et al.21, for example, to help old people with dementia, a reminder application was created for smartphones as an instrument to collect data and register important information, and that when used resulted in the improvement of the recognition of the registers by the elderly. While a study by Pestili and Betti22 developed the application “Remember”, used with the purpose of postpone the loss of cognitive functions in old people with Alzheimer.

Regarding weakness, Santos et al.23 developed an application in platform android, able to identify quickly and safely the characteristics of fragility syndrome in old people, configuring the application as a prevention strategy, since the early detection of fragility is very important for the treatment. Rodriguéz et al.24 used this technology to monitor physical activity allied with healthy habits on an everyday basis, confirming that new technologies are useful to promote healthier lifestyles and that their effects are beneficial in relation to arterial aging.

As regards experiment reports or scientific papers describing the use of applications to perform functional exercises in the elderly, there are not many, despite the stage of development of the technological resources used in the health area25. This might be explained by the fact that this is something relatively new in the scientific and research areas. Therefore, considering this information, this study might be seen as an innovation for the aging and for the physical therapy areas of interest, since its proposal includes the access to technology through the applications, which has not been mastered by most of the elderly, and leads to health through functional exercises.

For the steps of construction of a health application, which in this study comprised a series of exercises to develop the functional capability of old people, it is important to consider that there was correlation between the theoretical background and the selection of content for this project. The content was made available by the team of physical therapists while the definition of programming phases using technological concepts was carried out by the team designing the project. Therefore, the importance of interdisciplinarity among the professionals of communication and design, the programming team and the physical therapists for the final quality of the work was confirmed.

The structure of an application requires knowledge about its users, taking into consideration the accessibility that comprises understandable vocabulary, content that is easy to be read and clear audio instructions. In this sense, it is necessary that the team takes into consideration the users’ needs, since many times old people have difficulties to deal with new technologies, due to the fast evolution of devices. Therefore, new technologies might be seen as a barrier to their use, generating the sensation of exclusion and lack of skills, limiting the interaction between the old person and the interactive system26), (27.

One example of the importance of being aware of the users of an application is the study by Blackman et al.28, where the participants were adolescents, the technology was made available to smartphones through competitive games that led to physical activity, that is, competitiveness, which is common in this age range, was used to make the application more appealing to its users.

Taking into consideration the several advances in technologies, including the use of applications, it becomes clear how relevant they are in the social change process, since they promote the appearance of a new society where technological resources are part of the everyday life of most individuals, including the elderly, providing them with great advance in relation to the health area, promoting resources that can be used to prevent and treat comorbidities common to the aging process. A study by Lolli et al.29 reported that the elderly tend to consider the interaction with technology significant for their insertion in the society, in addition to making their daily activities easier.

In relation to limitations, we might consider that for being a field in expansion in the physical therapy area, there were difficulties of communication between the team of physical therapists and the information technology professionals. Specific knowledge in both areas was needed for the programming of phases and tabs that appeared in the application, aiming at offering to the final user, a user friendly technology, enjoyable navigation and that could meet the needs inherent in the aging process. Liao et al.30 presented a study that analyzed the users’ perception when questioning whether the needs matched the current functions offered in applications, highlighting that the efficacy of the application, allied to the activities proposed and design were the features that called the users’ attention.

Another limitation to the use might be the high cost to develop studies like these. Fortunately, this study was financially supported by CNPq, which granted funds for the research, but it is necessary to understand that more investment from the public and private sectors are vital to promote advances in the health technology area.

The development of the application “Idoso Ativo” (Active Aging) aims at providing the elderly with one more option of planned physical exercises. Due to the increasing search for a healthier lifestyle, with the perspective of more independent movements, the approach proposed is to ally this habit to the new technological support.


The development of an application despite being inserted in the health context, represents something new when associated to the proposal of functional exercises destined to old people, and it seems to be more and more important to develop projects that promote the relation between the use of technology and physical activity in the aging process.

The application designed and presented contributes to the development of important future scientific studies seeking to evidence its efficacy and usability as well as its content, besides presenting an innovative resource allied to the promotion of old people’s health.
