Basics of Biomechanics #6: Time Normalisation of Signals

Welcome back to Basics of Biomechanics, a series of blog posts covering foundational topics in the field using practical, data-driven examples. This post gives an introduction to batch analysis of signals using a technique called time normalisation. Biomechanical testing often involve protocols with repeated movement activities. For example, in a test involving running or walking,Continue reading “Basics of Biomechanics #6: Time Normalisation of Signals”

Basics of Biomechanics #5: Extracting Outcomes

Welcome back to Basics of Biomechanics, a series of blog posts covering foundational topics in the field using practical, data-driven examples. In this post we cover one of the fundamental approaches to analyzing biomechanical measurement data: extracting discrete outcomes.  In order to capture human movement in adequate detail, biomechanical equipment generates thousands, if not tensContinue reading “Basics of Biomechanics #5: Extracting Outcomes”

Basics of Biomechanics #4: Conditioning Signals

Welcome back to Basics of Biomechanics, a series of blog posts covering foundational topics in the field using practical, data-driven examples. In biomechanical analysis, before we can extract useful outcomes from our measurements we often need to “clean them up” in order to improve their quality or usefulness. As we will see, in many cases,Continue reading “Basics of Biomechanics #4: Conditioning Signals”

Basics of Biomechanics #3: Calculating Signals

Welcome back to Basics of Biomechanics, a series of blog posts covering foundational topics in the field using practical, data-driven examples. In this post we will look at some details about calculating biomechanical signals from our measurement data.  As we saw in the previous blog post, some biomechanical analysis can be performed directly with measuredContinue reading “Basics of Biomechanics #3: Calculating Signals”

Basics of Biomechanics #2: Analysing Signals

Welcome back to Basics of Biomechanics, a series of blog posts covering foundational topics in the field using practical, data-driven examples. In this post we cover a fundamental aspect of biomechanical analysis: working with time-series data or signals. Signals are the bread and butter of biomechanical analysis. Since these are the streams of information thatContinue reading “Basics of Biomechanics #2: Analysing Signals”

Basics of Biomechanics #1: Analysing Time

Welcome to Basics of Biomechanics, a series of blog posts covering foundational topics in the field using practical, data-driven examples. In this first post we look at the importance of knowing exactly where you are in your data timeline. Biomechanical analysis involves the interpretation of time-varying signals measured during a physical activity of interest. Therefore,Continue reading “Basics of Biomechanics #1: Analysing Time”

Join us at this year’s BIG event in Pretoria

The annual meeting of the South African Biomechanics Interest Group will be hosted on 18 September 2019 at the Sport, Exercise Medicine and Lifestyle Institute at the University of Pretoria. The inaugural BIG meeting was held last year at the Neuromechanics Unit at Stellenbosch University, and we are looking forward to another opportunity to connectContinue reading “Join us at this year’s BIG event in Pretoria”
