Resistance Training on Endocrine System

Can be manipulated naturally by Resistance Training

Can enhance/develop of Target Tissues

*Improves Performance
Chemical Messengers that are:
- Synthesized
- Stored
- Released in blood

by Endocrine Glands
Endocrine Glands
Body Structures specialized for:
- Secretions

*maybe other cells
The Study of the Interactions between:
- Nervous System
- Endocrine System
Nucleus Receptor for Hormones are in these hormones

Target Tissue
The tissue for which hormones are created for
Myosin Heavy-Chain Proteins (MHC)
Can go through a change in their molecular structure
- From IIx to IIa
Anabolic Hormones
Hormones promoting:
- Tissue Building
- Block catabolic hormones
Catabolic Hormones
Attempt to degrade cell proteins to support:
- Glucose synthesis
Lock-and-Key Theory
The Receptor = Lock

The Hormone = Key
A given receptor partially:
- Interacts with Hormones that not specifically designed for it
Allosteric Binding Sites
When a substance Other than Hormones can:
- Enhance/Reduce cellular response to the Primary Hormone
Inability of a hormone to interact with a receptor
Hormone-Receptor Complex
A binded Hormone/Receptor
- Shifts the receptor
- Activates Receptor
- Opens cells Nucleus
Polypeptide Hormones
Hormones made up of Amino Acids

i.e. HGH, Insulin
Secondary Messengers (STAT)
Messengers that get polypeptide hormones messages across cellular membranes
Heavy Resistance Exercise and Hormonal Increases
Specific Force Produced in Activated fibers:
- Stimulates: receptor and membrane Sensitivities
- To anabolic factors:
- Includes: hormones
- Leads to muscle growth and strength training
Hormone link to Resistance Training
Hormone responses are tightly linked to:
- Characteristics of the Resistance Exercise Protocol
Diurnal Variations
Normal fluctuations in Hormone Levels throughout the day
Large Muscle Group Training and Hormone Response
Large Muscle Group Exercise results in:
- Acute increased Serum Total Testosterone concentrations in men
Growth Hormone (Reactions)
- Normal development of children

- Plays a vital role to Adapting to stress of Resistance Training

Secondary Effects of HGH Injections:
- Change in muscle size/strength
- Hypertrophy
Proteolytic Enzymes
Enzymes that break down proteins
Cortisol Hormone and Resistance Training
Resistance Training:
- High Volume
- Large Muscle Groups
- Short Rest Periods


Increased Serum Cortisol Values (if acute, maybe a sign of muscle tissue remodeling)
General Concepts (Resistance Training and Endocrine Response)
- More Muscle fibers recruited = more muscle remodeling

- Only muscle fibers activated by Resistance Training are Subject to Adaptation
To Increase Serum Testosterone Concentrations
- Large Muscle Group Exercise

- Heavy Resistance Training (85%-95% of 1RM)

- Moderate-High Volume of Exercise

- Short Rest Intervals (30-60 secs)
To Increase Growth Hormone Levels
- Use workouts with High Lactate Concentrations

- High Intensity (10RM/Heavy Resistance)

- High Total Work (3 sets)

- Short Rest Periods (1 min)

- Supplement Diet with Carbohydrate and Protein Before/afterwards workout
To Optimize Responses of Adrenal Hormones
- High volume
- Large Muscle Groups
- Short Rest Periods

- Vary training protocol/rest period length/volume

- Adrenal gland chronic catabolic response of Cortisol
Growth Hormone (Function)
- IGF-1
- Protein Synthesis
- Growth
- Metabolism
Thyroid-Stimulating Hormone (Function)
- Thyroid Hormone Synthesis
- Secretion
Luteinizing Hormone (Function)
- Ovulation
- Secretion of Sex Hormones in Ovaries/Testes
Insulin Hormone (Function)
- Glycogen

- Glucose Entry into Cells

Involved In:
- Protein Synthesis
Glucocorticoids (Function) (Cortisol, Cortisone, etc)
- Amino Acid Incorporation into Proteins

- Conversion of Amino Acids into: CHO

- Normal Blood Sugar Levels

- Glucose

- Fat use
Insulin Like Growth Factor -1 (Function)
Increase Protein Synthesis in Cells
Epinephrine (Function)
- Cardiac Output
- Blood Sugar
- Glycogen Breakdown
- Fat Metabolism
Norepinephrine (Function)
Same as Epinephrine

- Constricts Blood Vessels
Testosterone (Function)
- Growth
- Protein Anabolism
- Development/Maintenance of Male Sex Characteristics
