Unit 5: Flexibility and Balance · Lesson 7
Flexibility and Balance - Lesson 7
What this lesson is for
- Identify the five most common flexibility-related injuries in adolescent athletes and their prevention strategies
- Explain why hypermobile individuals need joint stability training more than additional stretching
What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
1 Corinthians 6:19
Injury prevention through flexibility is one of the most important long-term benefits of a consistent stretching practice. While the relationship between flexibility and injury prevention is nuanced — extreme flexibility is not always safer than normal range — adequate functional flexibility in key areas significantly reduces common athletic injuries. Most common flexibility-related injuries in adolescent athletes: hamstring strains (hamstrings too tight relative to quad strength), hip flexor strains (hip flexors shortened from prolonged sitting), ankle sprains (reduced ankle dorsiflexion increases sprain risk), lower back pain (hip flexor and hamstring tightness affects lumbar mechanics), shoulder impingement (chest and internal shoulder rotators too tight, pulling the shoulder blade into a forward-rounded position). Prevention strategies: Hamstring health: stretch hamstrings after every workout; build hamstring strength with Romanian deadlifts and hamstring curls. Hip flexor health: stretch hip flexors daily, especially if you sit for extended study periods; strengthen glutes. Ankle health: daily ankle circles, calf stretching, and single-leg balance work. Lower back health: prioritize hip flexor and hamstring stretching; strengthen the core. Shoulder health: balance pushing and pulling movements in training; stretch chest and lats. Warning — hypermobility: some individuals (especially females) are naturally hypermobile — their joints move beyond normal range. Hypermobile individuals are not protected from injury by their flexibility; they need joint stability training (strengthening the muscles around hypermobile joints) more than additional stretching. Know your individual needs.
Homework
Address your highest-risk area from today with targeted stretching or strengthening at least 4 days this week.
Note for the parent
Today's lesson covers Flexibility and Balance - Lesson 7. Estimated time: 35 minutes. Encourage independent work but be available for questions.
The first three of this lesson's 10 questions
Which flexibility-related injury is most often caused by hip flexors shortened from prolonged sitting?
Show the answer
Answer: Hip flexor strain
Reduced ankle dorsiflexion primarily increases the risk of which injury?
Show the answer
Answer: Ankle sprain
To improve hamstring health and reduce strain risk, this lesson recommends stretching hamstrings after every workout AND building hamstring strength with which exercises?
Show the answer
Answer: Romanian deadlifts and hamstring curls
Another 7 questions follow in the lesson itself, each one graded the moment it is answered.
