  22. Benefits of Good Flexibility Factors Affecting Flexibility Assessment of Flexibility Evaluating Body Posture Muscular Flexibility Prescription Contraindicated Exercises Preventing and Rehabilitating Low-Back Pain Critical Thinking • Carefully consider the relevance of stretching exercises to your personal fitness program throughout the years. How much importance do you place on these exercises? • Have some conditions improved through your stretching program, or have particular exercises contributed to your health and well-being?

  23. Ballistic (dynamic) stretching: Exercises done with jerky, rapid, bouncy movements Slow-sustained stretching: Exercises in which the muscles are lengthened gradually through a joint’s complete range of motion Proprioceptive neuromuscular facilitation (PNF): Stretching technique in which muscles are stretched out sequentially with intermittent isometric contractions Benefits of Good Flexibility Factors Affecting Flexibility Assessment of Flexibility Evaluating Body Posture Muscular Flexibility Prescription Contraindicated Exercises Preventing and Rehabilitating Low-Back Pain Key Terms

  24. Mode Static or dynamic to include every major joint Intensity To the point of mild discomfort Repetitions At least 4 times Hold the final stretched position for 10 to 30 seconds Frequency 2 to 3 days per week Benefits of Good Flexibility Factors Affecting Flexibility Assessment of Flexibility Evaluating Body Posture Muscular Flexibility Prescription Contraindicated Exercises Preventing and Rehabilitating Low-Back Pain Guidelines forDeveloping Flexibility
