Balance Training in Recreational Gym Users - Essay Example

Download file to see previous pages Questionnaires are used to provide information on demographics and participation in balance activity within a gym setting. Questionnaires are a cost-effective form of the survey, easy to analyze, non-confrontational and a familiar format for participants to complete. They are a good way of obtaining data with reduced bias (Walonick 2004). They have been used previously to ascertain balance training participation and behavior both as an isolated activity (McInnes 2004) and also as part of the multi-modal regimen (Resnick 2000). They are also effective for the measurement of variables such as motivation, barriers to, and promoters of balance exercise (Kline 2000). The convenience of the setting of the gym and the availability of participants already predisposed to regular exercise informs the choice of venue at which to conduct the survey.

All participants who took part in the survey were gym users, male and female, aged 20-80 years. Participants are surveyed from this age range as literature has shown the benefits in reduction of injury rates and falls from balance exercise in the young and elderly ( see for example Handall 2001, Hong 2000). Each respondent had been a member of the gym for more than 12 months and reported attendance of once a week or more.
The absence of population lists and sampling frames means it is not possible to determine whether the gender difference (or similarities) is a reflection of the gym user population. A minimum of 85 questionnaires was completed to produce a power calculation of greater than 80% in relation to the aims of the study, as specified by Altman,1991.  ...Download file to see next pagesRead More
