Patient cramping throughout his muscles. Losing muscle mass
Vegan lifestyle
Sometimes skips meals.
Background Information
Muscular levels of Organization
Molecular level
Actin & Myosin
Microscopic level
Sarcomere & Myofibrils
cell level
Myoblasts & Myofibers
tissue level
neuromuscular junctions & fascicles
organ level
major skeletal muscles of the body
Excitation-Contraction Coupling
Step 1
Acetylcholine released from the axon terminal binds to receptors on the sarcolemma.
Step 2
An axon terminal is generated and travels down the T-Tubule
Step 3
Ca2+ is released from the sarcoplasmic reticulum in response to the change in votage
Step 4
Ca2+ binds tropinin; Cross-bridges form between between actin &myosin.
Step 5
Acetylcholinesterase removes acetylecholine from the synaptic cleft.
Step 6
Ca2+ is transported back into the sarcoplasmic reticulum.
Step 7
Tropomyosin binds active sites on actin causing the cross bridge to detach.
Fuels & other compounds needed for muscle
ATP
Supplies energy to move and detach cross bridges
Operate calcium in the SR
operate Na+ -K+in the plasma membrane
3 Pathways
Anaerobic Metabolism
Creation of energy
Anaerobic Glycolisis
Transformation of glucose to lactate
Creatine Phosphate
store energy
Protein
used by the body for fuel or for anabolic processes
Fat
major fuel for light- intensity to moderate intensity exercise
Carbohydrates
main source of fuel for enduranance
Water
most important for intake
Vitamins and minerals
B Vitamins
Energy production cycle
Antioxidants
decrease free radical damage
improve recovery time
decrease muscle damge
help immune response
Nutrition
more protein
help gain muscle mass
Eggs, fish, chicken are full of protein.
muscle metabolism
ATP provides energy for muscle contraction
Homeostatic set point
Skeletal muscle
Maintain temperature of the body
Create contractions such as shivering
Muscle growth
Physical training can alter the appearance and performance
Muscle and blood flow
Vegan diet
his diet does not allow intake of protein
Lack of actin and myosin
joins amino acids inside muscle
his diet is mainly fruits
increased cramping
disturbances to
fluid balance
electrolyte balance
possibility of reduction of of body exchangeable sodium stores
Change in workout retain &pushing body to extreme
Losing muscle mass
strict diet and cutting out certain things your body needs.
possibility of not getting enough protein
diet change
New weight training program
Skipping meals
Physiological coupling is the process of converting an electrical stimulus to a mechanical process.
