Association between fat and fat-free body mass indices on shock attenuation during running

New #OpenAccess publication in Journal of Biomechanics: doi.org/10.1016/j.jb...

#BiomechSky
Association between fat and fat-free body mass indices on shock attenuation during running Bernard X.W. Liew, Xuqi Zhu, Xiaojun Zhai, Stuart A. McErlain-Naylor, Christopher McManus Abstract High amplitudes of shock during running have been thought to be associated with an increased injury risk. This study aimed to quantify the association between dual-energy X-ray absorptiometry (DEXA) quantified body composition, and shock attenuation across the time and frequency domains. Twenty-four active adults participated. A DEXA scan was performed to quantify the fat and fat-free mass of the whole-body, trunk, dominant leg, and viscera. Linear accelerations at the tibia, pelvis, and head were collected whilst participants ran on a treadmill at a fixed dimensionless speed 1.00 Fr. Shock attenuation indices in the time- and frequency-domain (lower frequencies: 3–8 Hz; higher frequencies: 9–20 Hz) were calculated. Pearson correlation analysis was performed for all combinations of DEXA and attenuation indices. Regularised regression was performed to predict shock attenuation indices using DEXA variables. A greater power attenuation between the head and pelvis within the highe

E-textiles for sports and fitness sensing:
Current state, challenges, and future opportunities

Open Access: mdpi.com/1424-8220/24...
E-textiles have emerged as a fast-growing area in wearable technology for sports and fitness due to the soft and comfortable nature of textile materials and the capability for smart functionality to be integrated into familiar sports clothing. This review paper presents the roles of wearable technologies in sport and fitness in monitoring movement and biosignals used to assess performance, reduce injury risk, and motivate training/exercise. The drivers of research in e-textiles are discussed after reviewing existing non-textile and textile-based commercial wearable products. Different sensing components/materials (e.g., inertial measurement units, electrodes for biosignals, piezoresistive sensors), manufacturing processes, and their applications in sports and fitness published in the literature were reviewed and discussed. Finally, the paper presents the current challenges of e-textiles to achieve practical applications at scale and future perspectives in e-textiles research and develo

Looking forward to this session! The focus will be on self-promotion in professional environments (why it matters, how to do it) but also on allyship and promoting the achievements of others. Open (and free) to all ISBS members.

Women in Biomechanics (Open to All): #IAmRemarkable Workshop
 
21:15-22:45 GMT Thu 8th Feb (Session 10)
 
Free for ISBS members – details: isbs.org/conferences/...
#IAmRemarkable is a global movement that empowers everyone, including underrepresented groups, to celebrate their achievements in the workplace and beyond, while challenging the social perception around self-promotion. In this interactive session (it will not be recorded!), you will participate in group discussions and exercises to increase your comfort and confidence in self-promotion.

New preprint: When and How to Deviate from a Preregistration osf.io/preprints/ps... I hope this helps researchers to reflect on the consequence of deviations from preregistrations by evaluating the test's severity and the validity of the inference.

As @quentinandre.bsky.social and @ulrichschimmack.bsky.social correctly predicted, I recommend sequential analysis: lakens.github.io/statistical_... I actually coined the term SESOI in my 2014 paper on sequential analysis.

The addbiomechanics.org tool is now citable!

Article: journals.plos.org/plosone/arti...

Automatic model scaling for more accurate inverse kinematics and dynamics, in minutes.

Fun collab led by Karen Liu, kicked off by a survey here :-)

Much improved in past few months. Give it a try!
Illustration of addbiomechanics's role in the motion capture and data processing pipeline. Automatic scaling by addbiomechanics takes just a few minutes, compared to about one day for an expert, and results in severalfold lower errors and residual forces and torques.

Hi, I'm new here 👋🏻

Definitely skeptical but willing to dive in and see if I can be convinced this place is the future of biomechanics communication and discussions.

Hopefully I'm wrong and we'll all be here for years to come 🤞🏻
