Background and Study Aim. Non-sport activities like traditional games can be a practical way to promote physical activity (PA) during physical education (PE) lessons, especially among those who are less inclined towards sports. The purpose of this study is to compare the PA variables and acceptance between playing traditional games and free-play during physical education lessons among secondary school students.
Material and Methods. Fifty-six (n = 56) subjects participated in this study wore accelerometers for a total of 40 minutes during each PE lesson to record PA. In the first week, a 40-min free-play PE lesson was done while in the second week, a 40-min PE lesson incorporated with traditional games (TG-PE lesson) was done. After following both lessons, subjects filled up a questionnaire on acceptance of TG-PE and free-play PE lessons.
Results. The mean total activity count (p < 0.05) and time spent in moderate-to-vigorous physical activity (MVPA) (p < 0.05) were 20% and 19% greater respectively during TG-PE lesson compared to free-play PE lesson. The mean acceptance scores showed students preferred playing TG (19.29 ± 4.21; p < 0.00) over free-play PE lesson (17.59 ± 3.13).
Conclusions. In conclusion, incorporating fun and meaningful activities such as TG during PE lessons can serve as an alternative strategy to promote PA during school hours. Further studies are warranted to determine other types of TG that may promote PA among secondary school students.
Electrical Resistivity Tomography (ERT) is a commonly used tool in near surface geophysical surveys to investigate numerous geological, environmental, and engineering problems including landslides. In this study, an electrical resistivity survey was conducted at a landslide area, located in Bukit Setiawangsa, Kuala Lumpur, Malaysia. On 29th December 2012, a luxury hilltop bungalow was split into two when a 43m retaining wall was collapsed after a continuous heavy downpour. 2-D electrical resistivity survey have been acquired along two (2) profiles on the adjacent slope in an effort to mitigate the risks of instability, especially during the rectification work of the failed slope using a Schlumberger Array. It produced useful information about the geometry and characteristics of the study area. In addition, the 2-D resistivity method was performed to determine the behaviour of electrical resistivity underlying the slope areas and estimate the location of the failure surface. Four (4) boreholes were also drilled to obtain engineering properties of the study area such as soil classification, moisture content, soil hardness and SPT N-value. In order to develop the relationship between resistivity and engineering properties, a comparison between soil hardness and the resistivity value was made. Results from the ERT indicated the presence of zones with low resistivity values identified as percolated water in permeable loose soil, which was believed to be the potential slip surface. The findings of this study also showed that the electrical resistivity imaging coupled with borehole drillings were useful tools for the characterisation of slope failure via subsurface profiles and engineering properties of soil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
