Real-Time Biofeedback of Performance to Reduce Braking Forces Associated With Running-Related Injury: An Exploratory
The Journal of Orthopaedic and Sports Physical Therapy
|December 12, 2018
Summary
This study shows an 8-session gait retraining program significantly reduced peak braking forces in female runners. The program improved running mechanics by increasing step frequency and decreasing step length, potentially aiding injury prevention.
Area of Science:
- Biomechanics of running
- Gait analysis and retraining
- Sports injury prevention
Background:
- High incidence of running-related injuries linked to elevated peak braking forces (PBFs) and vertical loading rates.
- Gait retraining is a proposed intervention to mitigate these loading parameters.
Purpose of the Study:
- To determine if an 8-session gait retraining program can decrease PBFs in female recreational runners.
- To identify kinematic strategies adopted by runners to achieve reduced PBFs.
Main Methods:
- 12 female recreational runners with high PBFs (>0.27 body weight) participated.
- An 8-session gait retraining program incorporating real-time biofeedback of braking forces was implemented.
- Kinetics and kinematics were assessed at baseline and follow-up using repeated-measures ANOVA.
Main Results:
- A significant 15% average reduction in PBF was observed (P = .001).
- Step frequency increased by 7% (P = .024), and step length decreased by 6% (P = .020).
- The observed changes in gait were successfully integrated into the runners' natural running patterns.
Conclusions:
- The gait retraining program effectively reduced PBFs in female recreational runners.
- The reduction in PBFs was associated with increased step frequency and decreased step length.
- Further research is warranted to confirm the efficacy of this gait retraining program as an injury prevention strategy.

Real Gases: Effects of Intermolecular Forces and Molecular Volume Deriving Van der Waals Equation
39.0K
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and empirical and molecular formula problems to determining the density and molar mass of a gas. However, the behavior of a gas is often non-ideal, meaning that the observed relationships between its pressure, volume, and temperature are not accurately described by the gas laws.

Real Time RT-PCR
65.1K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.

Wald-Wolfowitz Runs Test II
552
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...

Wald-Wolfowitz Runs Test I
960
The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.

Electromotive Force
30.2K
Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one substance to...

Reducing Line Loss
391
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...
