What is undertraining?
|
Type of training an athlete would undergo between competitive seasons or during active rest
|
|
|
What is acute overload?
|
Athlete is stressing the body to the extent that improvements and adaptations are being made
|
|
|
What is overreaching?
|
Brief period of heavy overload without adequate recovery
|
|
|
What are the causes, symptoms, & treatments for overtraining syndrome?
|
• Overtraining is the point at which an athlete experiences physiological maladaptations and chronic performance decrements.
• Symptoms: appetite and weight loss, sleep disturbances, depression, loss of vigor, etc • Treatment: follow periodization training procedures, adequate carb intake, rest, etc |
|
|
How is the Autonomic nervous system affect during overtraining?
|
Sympathetic: increased RHR and BP. Loss of appetitie, decreased body mass, sleep disturbances, elevated basal metabolic rate
Parasympathetic- quick to fatigue, decreased RHR and BP, rapid HR recovery after exercise |
|
|
What hormonal changes occur during overtraining?
|
Cortisol and Cytokines increase
Testosterone and Thyroxine decrease |
|
|
What is tapering and how does it improve performance?
|
Reduction in training leading up to a major performance event- 4 to 28 days before.
Strength is gained. Energy reserves are restored. No loss of VO2max. May increase economy. Recovery of strength and power is attributed to modifications of the muscle’s contractile mechanisms and myosin molecules. |
|
|
What happens to muscle strength, power & endurance following detraining?
|
It all decreases. First, oxidative enzyme activity decreases, then eventually glycolytic enzyme activity decreases, muscle glycogen is depleted, blood lactate increases.
|
|
|
What happens to speed, agility, and flexibility following detraining?
|
Flexibility is lost rather quickly. Speed and agility-not so much, but still decrease.
|
|
|
What happens to cardiorespiratory endurance following detraining?
|
•Increased submax HR
•Decreased SV, CO, and VO2max •Associated with decreased plasma volume Research indicates that at least 3 sessions per week at 70% of max intensity are needed to maintain aerobic conditioning! |
