This paper reviews the literature on the problem of information overload. The literature reveals that although the problem of information overload has existed for many years, in recent years the problem has become more widely recognised and experienced. Information overload has been defined as the receipt of more information than is needed or desired to function effectively and further the goals of an individual or organization. More formally, receipt of undesirable or non-relevant messages that result in an economic loss for the recipient represents information overload. Information overload costs businesses and individuals valuable time, effort and additional resources. Information overload has been exacerbated by the rapid advances made in information and communication technology A Theme stressed in the literature is the paradoxical situation that, although there is an abundance of information available, it is often difficult to obtain useful, relevant information when it is needed. Some solutions put forward to reduce information overload are; time management, information literacy, personal information management, information quality filters, e-mail etiquette policies, knowledge organization, maintaining currency, vocabulary control, information design, the role of information specialist, and software solutions such as intelligent agents, filtering, and customization of search results.

The purpose of this study is to investigate the effect of respiratory muscle strengthening exercise using a incentive spirometer on the improvement of forced vital capacity (FVC), maximal inspiratory pressure (MIP) and thoracic mobility (TM) in healthy college students. Thirty subjects were participated, and Pony FX was used to measure FVC and MIP, and flexible ruler was used to measure thoracic mobility. The measurements were implemented before the inspiratory muscle strengthening exercise with incentive spirometer and after inspiratory muscle strengthening exercise with it. FVC and MIP and MEP and chest circumference data were normally distributed in Kolmogorov-Smirnov (p>.05), and a paired t-test was employed to analyze the statistical differences of measurements between before and after exercise. There was a significant difference in FVC (p=.001), however the post -measurement was lesser than pre-measurement. And there were no significant difference in MIP (p=.195), and chest circumference (p=.781). The results shows that once inspiratory muscle strengthening exercise with incentive spirometer could not induce the increasing FVC, MIP and TM. Therefore, aerobic exercise and inspiratory muscle strengthening exercise during a certain period should be necessary to improve an aerobic capacity including with parameters of FVC, MIP and TM in healthy
