This article reports the findings of a scoping review of the use of small-sided games (SSGs) as a teaching or coaching pedagogy across four game categories. The selection criteria included empirical research available online, published after January 1 2006 and prior to December 31, 2016, in an academic journal. The data were analysed through an inductive thematic approach which generated two themes: Development and Practical considerations. This review found that SSGs can be used as a deliberate pedagogy to elicit physiological responses for a training effect. Given that the variables associated with SSGs include pitch size, game intensity, and number of players, a key determining factor in the implementation of SSGs includes the objective of the practice activity.

Chitosan, a hydrophilic biopolymer industrially obtained by N-deacetylation of chitin, can be applied as an antimicrobial agent. It highlights the applications of chitosan as an antimicrobial agent against fungi, bacteria, and viruses and as an elicitor of plant defense mechanisms. A series of novel chitosan-sulfathiazole nanocomposite (CSFZ) films were prepared by using solvent casting method for wound healing application. Fourier transform infrared spectroscopy (FTIR) was employed to ascertain the interaction between negatively charged sulfathiazole and positively charged chitosan. Moreover, the antibacterial activity of the films was investigated against gram positive and gram negative microorganisms. It was found that all CSFZ films showed good inhibitory activity against all the tested bacteria as compared to control. The above analysis suggested that the CSFZ films could be used as potential candidates for wound healing application.
