The Running Gravitational Couplings [PDF]

open access: yes, 1998
We compute the running of the cosmological constant and Newton's constant taking into account the effect of quantum fields with any spin between 0 and 2. We find that Newton's constant does not vary appreciably but the cosmological constant can change by

Genetic Polymorphisms and Their Impact on Body Composition and Performance of Brazilians in a 105 Km Mountain Ultramarathon

open access: yesEuropean Journal of Investigation in Health, Psychology and Education, 2023
Although the studied polymorphisms affect muscular proteins, aerobic adaptations, and recovery, their influence on the anthropometric variables and performance in ultramarathon runners is still poorly understood.

‘Mind Your Business and Leave My Rolls Alone’: A Case Study of Fat Black Women Runners’ Decolonial Resistance

open access: yesSocieties, 2021
The Black female body has been vilified, surveilled, and viewed as ‘obese’ and irresponsible for centuries in Western societies. For just as long, some Black women have resisted their mischaracterizations. Instead they have embraced a ‘fat’ identity. But

Chemo-Sensitive Running Droplet [PDF]

open access: yes, 2005
Chemical control of the spontaneous motion of a reactive oil droplet moving on a glass substrate under an aqueous phase is reported. Experimental results show that the self-motion of an oil droplet is confined on an acid-treated glass surface.

Classification of higher- and lower-mileage runners based on running kinematics

open access: yesJournal of Sport and Health Science, 2019
Background: Running-related overuse injuries can result from the combination of extrinsic (e.g., running mileage) and intrinsic risk factors (e.g., biomechanics and gender), but the relationship between these factors is not fully understood.

Continuous Tracking of Foot Strike Pattern during a Maximal 800-Meter Run

open access: yesSensors, 2021
(1) Background: Research into foot strike patterns (FSP) has increased due to its potential influence on performance and injury reduction. The purpose of this study was to evaluate changes in FSP throughout a maximal 800-m run using a conformable ...

How Are Sports-Trackers Used by Runners? Running-Related Data, Personal Goals, and Self-Tracking in Running

open access: yesSensors, 2021
The purpose of this research is to explore the roles that sports trackers and running-related data play in runners’ personal goal achievement. A two-week diary study and semi-structured interviews were conducted with 22 runners to explore how runners ...

Ideal Combinations of Acceleration-Based Intensity Metrics and Sensor Positions to Monitor Exercise Intensity under Different Types of Sports

open access: yesSensors, 2022
This study quantified the strength of the relationship between the percentage of heart rate reserve (%HRR) and two acceleration-based intensity metrics (AIMs) at three sensor-positions during three sport types (running, basketball, and badminton) under ...

The QCD Running Coupling

open access: yes, 2020
We review the present knowledge for $\alpha_s$, the fundamental coupling underlying the interactions of quarks and gluons in QCD. The dependence of $\alpha_s(Q^2)$ on momentum transfer $Q$ encodes the underlying dynamics of hadron physics -from color ...
