Title IX

A federal law passed in 1972 that prohibits discrimination based on sex in educational programs receiving federal funding.

Strength

The maximum amount of force that can be exerted voluntarily by muscles, often measured as torque across joints.

Coordination

The ability to use multiple muscles in a coordinated sequence to perform a task, often independent of strength.

Juvenile Rheumatoid Arthritis (JRA)

A condition causing joint inflammation and pain, potentially affecting muscle development and strength.

Strength Development in Children

As children grow, strength generally increases, especially in boys, due to increased muscle mass. However, this pattern can be affected by conditions like JRA.

Performance Measures in Children

Strength, coordination, and other performance measures in children can vary widely due to factors like age, gender, and health conditions.

Vertical Jump Sex Differences at Puberty

During puberty, females gain more fat mass, which hinders movement, while males gain more muscle mass, which facilitates movement. This explains the larger difference in vertical jump performance between boys and girls at puberty, with girls plateauing and boys continuing to improve.

Throwing Distance Sex Differences

The difference in throwing distance between boys and girls is smaller than previously thought. However, boys still throw farther, likely due to their greater muscle mass and strength.

Throwing Mechanics Sex Differences

Males and females use different muscle groups and movement patterns when throwing. Males tend to engage larger muscles in their trunk and backswing, contributing to greater throwing velocity.

Running Speed Sex Differences

Differences in running speed are larger in standing starts than in running starts. This is because males have a faster initial acceleration due to more powerful muscles.

Practice and Throwing Performance

Regular practice and training can reduce the sex difference in throwing performance, as seen in aboriginal populations who use throwing for hunting. This suggests that practice influences skill development, even with inherent biological differences.

Standing Long Jump - Gender Differences

The standing long jump relies on strength, coordination, and practice. While boys tend to improve steadily, girls often plateau after puberty, possibly due to factors like hormonal changes and body composition.

Agility

The ability to change direction quickly and efficiently, often measured by the shuttle run test. It involves more precision and coordination than just speed.

Strength Development in Boys

The peak in strength acquisition occurs after the peak height velocity (PHV) in males because they need to grow first and then fill in with muscle mass.

Study Notes

Exam 3 Study Guide HHP3300

  • Title IX of 1972 prohibits sex discrimination in educational programs receiving federal funds
  • Strength and motor performance vary between males and females
  • Strength is primarily measured by torque (force across joints) in muscles
  • Coordination is crucial for combining muscle actions correctly
  • Force production typically increases with muscle mass (FFM) in late childhood and adolescence; males generally outperform females in strength, especially upper body strength.
  • Grip and pulling strength improve in late childhood and adolescence.
  • Recent data on grip strength reveals minimal differences between boys and girls in late childhood, but significant differences arise during puberty.
  • Endurance performance generally follows similar trends across genders in late childhood, though some differences are observed.
  • Standing long jump difference between boys and girls is minimal in childhood but boys outperform in adolescence.
  • Agility (e.g., standing long jump, catching, running speed) and throwing distance show greater differences, with males performing better than females.
  • Timing and coordination differences during physical activities are observed between males and females.
  • Flexibility differences exist, with girls typically outperforming boys, due to estrogen levels.
  • Ratio of force-producing tissue mass to overall body mass influences acceleration during physical activities.
  • Sex differences in performance may be related to variation in body composition and muscle maturation.
  • Physical performance is sometimes affected by biological maturation and body size.
  • Biological maturation in females occurs approximately 2 years earlier than in males; girls also enter puberty earlier than boys.
  • Maturity status can be classified as early, average and late.
  • Early maturing athletes may exhibit advantages in certain sports.
  • Maturation varies between individuals and may impact an athlete's performance in different ways.
  • Participation in youth sports often decreases in transition to adolescence.
  • Socioeconomic status can influence physical activity levels in children and adolescents.
  • Factors like biological, psychological, social, and physical environment can affect physical activity.
  • Girls' soccer and basketball have a higher incidence of knee injuries.
  • Physical activity levels decrease in adolescence and adulthood compared to childhood.
  • Dietary intake and energy expenditure influence growth and maturation.
  • Increased physical activity during early childhood may be beneficial for growth and maturation.
  • Excessive or intensive training may hinder growth.
  • Physical activity levels are often lower in individuals with chronic diseases/disabilities.
  • Overweight and obesity are prevalent and are associated with a variety of negative health outcomes in children.
  • Obesity tends to increase the risk of chronic diseases.
  • Obesity during childhood and adolescence can have long-term consequences.
  • Different types of chronic conditions (e.g., anorexia nervosa, asthma, cystic fibrosis, type 1 diabetes) can affect growth, physical activity, and physical performance.
  • Extremely low birth weight may lead to deficient physical performance, slow motor development and coordination.
