Coefficient of Correlation01:12

Coefficient of Correlation

The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the strength of the linear...
Hierarchy of Motor Control01:18

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
Correlations02:20

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
Spearman's Rank Correlation Test01:20

Spearman's Rank Correlation Test

Spearman's rank correlation test, also known as Spearman's rho, is a nonparametric method for assessing the strength and direction of association between two variables. This test is particularly valuable when the data distribution is unknown or when the assumption of normality does not hold. Named after the English psychologist and statistician Dr. Charles Edward Spearman, it serves as the nonparametric counterpart to Pearson's correlation coefficient.
Spearman's test calculates correlation by...

Summary
This summary is machine-generated.

Motor coordination (MC) inversely relates to body mass index (BMI) in children. Higher BMI correlates with poorer MC, with this trend strengthening in childhood and weakening in adolescence.

Area of Science:

  • Pediatric Health
  • Human Movement Science
  • Obesity Research

Background:

  • Childhood obesity is a growing public health concern.
  • Motor coordination (MC) is crucial for physical development and daily activities.
  • Understanding the relationship between body mass index (BMI) and MC is important for early intervention.

Purpose of the Study:

  • To investigate the association between motor coordination and body mass index in children aged 6-14.
  • To analyze how this association changes across childhood and early adolescence.

Main Methods:

  • Cross-sectional study of 7175 children (ages 6-14).
  • Body mass index (BMI) calculated from measured height and weight.
  • Motor coordination (MC) assessed using the Kiphard-Schilling body coordination test (KTK).
  • Spearman's rank correlation and Kruskal-Wallis tests were employed.

Main Results:

  • Negative correlations between MC and BMI were observed, ranging from 0.05 to 0.49.
  • The strongest inverse relationship was found at age 11 for both genders.
  • Significant differences in MC existed between normal weight, overweight, and obese children, with obese children having the lowest MC scores.

Conclusions:

  • Motor coordination (MC) shows an inverse relationship with body mass index (BMI) throughout childhood and early adolescence.
  • The strength of this inverse relationship increases during childhood and decreases in early adolescence.
  • Overweight and obese children exhibit significantly lower motor coordination than normal weight children.
