Technology/Multimedia in sport both includes macro and micro-interventions. I'm going to research both aspects and see which appeals to me the most. Firstly lets see whats the difference.
Macro-technological interventions: Are those that involve equipment, external / internal alterations of joints or ingestion of a substance.
Micro-technological interventions: Are those practices, which make possible acquisition of sports skill's and include such things as bio-mechanical adjustments and repetitive skill exercises.
