Summary
Advanced badminton players exhibit distinct muscle synergies during smash shots compared to beginners. A shared synergy involves the external oblique for side bending, while advanced players show unique synergies potentially enhancing performance.
Area of Science:
- Biomechanics
- Sports Science
- Motor Control
Background:
- Muscle synergies are fundamental to complex motor tasks like badminton smash shots.
- Understanding differences in muscle activation patterns between skill levels can inform training strategies.
Purpose of the Study:
- To investigate and compare muscle synergies during the badminton smash shot between advanced and beginner players.
- To identify specific muscle activation patterns that differentiate skill levels.
Main Methods:
- Surface electromyography (sEMG) recorded muscle activity from trunk and upper limb muscles.
- Nonnegative matrix factorization (NMF) extracted muscle synergies.
- Scalar product (SP) quantified similarity between synergies.
Main Results:
- Beginner players displayed two synergies, while advanced players showed three.
- A common synergy, primarily involving the left external oblique (EO), was identified in both groups (SP=0.86).
- Advanced players exhibited an additional synergy with coactivation of internal oblique/transversus abdominis (IO/TrA) and forearm muscles at impact.
Conclusions:
- A core muscle synergy involving trunk stabilization and side bending is shared between beginner and advanced badminton players.
- Advanced players utilize additional, more complex muscle synergies, particularly involving the core and forearm, which may contribute to enhanced smash shot performance.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

02:54Evolutionary Relationships through Genome Comparisons
7.0K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

01:24Comparison Between Electrical And Gravitational Forces

There are four fundamental forces in nature: the gravitational force, the electromagnetic force, the strong nuclear force, and the weak nuclear force. To compare the numerical strengths of the first two, take two particles of the same kind. Since electrons are fundamental particles, they are a good example.
Since both are inverse square law forces, the distance gets canceled when the ratio of the two forces is considered. Instead, the ratio of the electrical and gravitational forces depends on...
