- This page emphasizes the significance of understanding body mechanics for dancers and active individuals, advocating for informed health choices related to nutrition, exercise, and stress management. It discusses kinesiology and injury prevention, highlighting the adverse effects of poor diet and inactivity. Key anatomical terms and health-related behaviors are introduced to promote optimal wellness among dancers, aiming to enhance quality and longevity of life.
- 8.2: The Six Dimensions of Wellness
- This page outlines the six dimensions of wellness: intellectual, occupational, physical, mental, social, and spiritual. Each dimension contributes to an individual's overall vitality and ability to adapt to life's challenges, emphasizing the importance of creativity, job satisfaction, fitness awareness, emotional awareness, community involvement, and alignment with personal values.
- 8.3: The Human Body
- This page discusses human anatomy, focusing on the 206 bones and 177 movable ones that enable movement through muscle action. It emphasizes the skeleton's symmetry and the role of joints, ligaments, and tendons in connecting bones and muscles. Additionally, it touches on the influence of gravity on movement, particularly in dance techniques.
- 8.4: Bone Health
- This page discusses the vital roles of bones, including support, protection, movement, blood cell production, and mineral storage. It explains the process of ossification and its importance in bone health from childhood to peak bone mass in the late teens to early twenties. After age 30, ossification slows, making calcium and a healthy diet crucial for maintaining bone strength.
- 8.5: Joints
- This page outlines the five types of joints in the human body that are crucial for dance, highlighting their importance for healthy movement. It specifies joints in both the upper (wrist, elbow, shoulder) and lower (foot, ankle, knee, hip) extremities, along with vertebrae in the spine. The joint types discussed include ball and socket, ellipsoid, saddle, hinge, and plane joints.
- 8.6: Ligaments
- This page discusses various ligaments that connect bones in joints, particularly focusing on the knee and hip. The knee contains four main ligaments: ACL, PCL, MCL, and LCL, each serving specific roles in joint stability. The iliofemoral ligament in the hip limits movement, while the iliotibial band supports the outer knee. Issues with the IT Band can lead to inflammation and pain.
- 8.7: Muscles
- This page provides an overview of voluntary skeletal muscles crucial for dancers, highlighting power muscles, rotator cuff muscles, foot and ankle muscles, calf muscles, oblique muscles, and hip muscles. It underscores the significance of these muscle groups in dance performance and emphasizes the necessity of proper technical training to prevent injuries.
- 8.8: Alignment
- This page emphasizes the importance of proper body alignment for dancers to enhance aesthetics, reduce injury risk, and promote career longevity. It highlights the plumb line as a reference for alignment and the benefits of maintaining a neutral pelvis. It also discusses the significance of knee alignment in plié and acknowledges various spinal and limb alignments, like kyphosis and tibial torsion, that can affect technique without undermining the need for proper alignment.
- 8.9: The Physics of Dance
- This page explores the physics of dance and jump height, highlighting factors like balance, center of gravity, and surface effects on movement. It references Kenneth Laws' resource for physics principles relevant to dancers and underscores the significance of self-reflection on exercise, diet, and lifestyle to address physical ailments. The text advocates for monitoring daily habits and making purposeful changes to enhance health and overall quality of life.
- 8.10: Nutrition
- This page emphasizes the importance of nutrition for physical performance and emotional well-being. It highlights that proper hydration and a balanced intake of macronutrients—proteins, carbohydrates, and fats—are vital for energy, muscle repair, and overall health. Micronutrients play a key role in energy release and healing. Healthy eating habits and staying hydrated are essential for athletes and dancers to enhance performance and facilitate recovery.
- 8.11: Injury Prevention
- This page discusses dance injuries, emphasizing their significance and the necessity for injury surveillance. It highlights injury prevention practices, focusing on dynamic alignment and muscle contraction, especially during jumps and landings. Functional Movement Screening (FMS) is introduced to assess dancers' physical capabilities, identifying strengths and weaknesses.
- 8.12: References
- This page offers a comprehensive list of references on athletic training, health, and anatomy, featuring key texts such as "Foundations of Athletic Training" and "Principles of Athletic Training." It includes recent studies on embryology and osteoporosis, serving as valuable resources for those looking to enhance their understanding of athletic training, wellness, body mechanics, and effective health practices.
