This study examined the influence of 12 different synthetic sport surfaces (bitumen, concrete, 3 samples of synthetic grass, and 7 samples of rubber surfaces) on ground reaction forces at landing in netball. Ground reaction force data were obtained for 10 skilled netball players at landing after performing a typical attacking netball movement pattern. Force–time histories of the maximum peak vertical ground reaction forces (VGRF), the initial peak VGRF, and peak braking forces were determined for each trial. Results of the a priori planned comparison analysis indicated that subjects demonstrated significantly longer time to maximum peak VGRF and initial peak VGRF when landing on grass, higher peak braking forces when landing on bitumen and concrete combined, and a significantly shorter time to peak braking force when landing on grass in comparison to other samples tested. It was concluded that the rubber surfaces tested demonstrated the potential for being the most suitable playing surface for minimization of injuries in netball.

Sport coaching is a multifaceted profession with many responsibilities. Coaches can have a profound effect on athletes that can be both positive and negative. Coaches have the ability to motivate athletes and increase their self-esteem. Conversely, negative effects of coaching may include athlete drop-outs, injuries, and loss of confidence. Coaches need to manage the coaching environment and create positive surroundings to ensure that athletes achieve their optimum potential. Managing a coaching environment refers to how coaches establish and maintain order. This paper explores the literature on behavior management in education and sport settings and aims to contribute to sport-coaching knowledge. General coaching tips for managing athlete behavior are suggested along with examples of potential coaching strategies.
