HIIT bad? Flashcards
What is HIIT?
HIIT is a form of exercise that involves short bursts of intense activity alternated with periods of rest or lower-intensity activity.
What is Overtraining Syndrome (OTS)?
OTS is consistent and severe non-functional overreaching consisting of a longer performance decrement for over 2 months, and severe physiological and psychological symptoms.
What can insufficient glucose uptake during intense training lead to?
Chronic fatigue and overtraining syndrome.
What are potential metabolic disruptions caused by excessive HIIT?
- Reduced glucose tolerance
- Reduced insulin sensitivity
- Lower glucose uptake into muscle cells
What is a consequence of increased production of reactive oxygen species (ROS) from excessive HIIT?
Muscle fatigue, impaired muscle force generation, impaired recovery, and overly oxidized muscle fibers.
How can chronic inflammation from repetitive HIIT affect mitochondrial function?
It can result in an over-expression of IL-6, leading to impaired electron transport chain (ETC) enzymes and diminished mitochondrial enzymes.
Why is polarized training recommended for endurance athletes?
To maximize the benefits of HIIT while maintaining a high volume of training.
What should individuals new to exercise be aware of regarding HIIT?
The potential negative effects of excessive HIIT to avoid overdoing their training volume.
What is a key recommendation for implementing HIIT effectively?
Ensure prolonged high-intensity training bouts are paired with adequate rest.
What should be monitored to manage training load and intensity in athletes?
Fatigue and stress levels.
What is a crucial aspect of HIIT training?
Recovery.
What is needed for a clearer understanding of HIIT’s upper limits?
A clearer identification of the upper limit of HIIT volume before adverse effects occur.
What remains unidentified in relation to overtraining?
A single definitive marker or molecular mechanism of overtraining.
What is a future research direction regarding HIIT?
Understanding the primary physiological mechanisms of overtraining in endurance athletes.
Fill in the blank: Proper carbohydrate intake is needed to limit ______ during HIIT.
fatigue
True or False: Disregarding rest periods can lead to overtraining.
True
What is a consequence of diminished mitochondrial enzymes due to HIIT?
Impaired muscle’s ability to generate energy.
What should be prioritized to separate the training stimulus from the recovery process?
Recovery.
