PA is used as a means of intervention especially because a number of prospective studies confirm its protective effect on adiposity (Fogelholm & Kukkonen-Harjula, 2000; Kay & Fiatarone Singh, 2006). However, PA intervention should reflect the current health condition and degree of obesity (Ball, Owen, Salmon, Bauman, & Gore, 2001; Petersen, Schnohr, & Sorensen, 2004). The result of the intervention is influenced by a number of factors such as its duration. This modifiable factor affects not only the effectiveness of the intervention but has a great influence on the participants' adherence to the intervention programme (Jakicic & Otto, 2005). Other factors include the intensity and frequency of intervention PA. For an overweight or obese individual, appropriate activity is low-intensity exercise carried out over a longer period of time (Donnelly et al., 2003).
