RT for injury prevention Flashcards
What are two outcomes of resistance training (RT) on muscle characteristics?
Increased fascicle length and muscle thickness
These changes contribute to enhanced muscle performance and injury prevention.
What specific type of loading is known to increase fascicle lengths?
Eccentric loading
Eccentric loading is particularly effective for muscle lengthening adaptations.
How quickly can eccentric training shift the length-tension curve?
After just one week of training
This adaptation is crucial for high force production at longer muscle lengths.
What is the significance of eccentric training for hamstring injuries?
It is relevant for injury prevention in muscles like the hamstrings that are often injured during lengthening contractions.
How does progressive training affect one repetition maximum (1RM) and muscle activation?
Increases 1RM and is correlated with increased EMG (electromyography)
Indicates higher muscle activation during resistance training.
What benefits does explosive resistance training provide for older populations?
Improves neuromuscular function and increases rate of force development
This leads to decreased injury risk.
What type of training is recommended for fall injuries in the elderly?
Power training using 25% to 50-60% of 1RM
Followed by progressive overload principles to improve overall strength.
What effect does resistance training have on insulin resistance in older adults?
Decreases insulin resistance and prevents sarcopenia.
What is a common target for injury prevention strategies in athletes?
Hamstring injuries
These injuries are prevalent and often require specific training interventions.
What type of contractions are recommended for hamstring injury prevention?
Eccentric-specific contractions such as the Nordic curl protocol.
What is the importance of a familiarization period in eccentric exercises for athletes?
To ensure proper technique and adaptation to eccentric loading.
What training method should be used for in-season training?
A periodization method.
What is a key consideration for athletes involved in running and start/stop motions?
The importance of resistance training (RT).
What principle is crucial for improving overall strength and neuromuscular function?
Progressive overload.
What is the challenge of determining exercise prescriptions for injury management?
Individualized approach is needed due to variability among populations.
How can the menstrual cycle affect female athletes during strength training?
Fluctuating hormones can affect ligament laxity and pain perception.
What is the effect of higher estrogen levels on injury risk?
May increase ACL injury risk and decrease pain perception.
What is the difference in impact between eccentric and concentric training on muscle structure?
Eccentric loading increases fascicle lengths, while concentric loading increases the angle of pennation.
What area requires further investigation concerning strength training?
The interaction between fluctuating hormones and injury prevention.
What additional research is needed in the context of resistance training?
Understanding how hypertrophy and structural remodeling interact with aging.
