Muscles
This muscle at the front of the thigh plays leg extension.
what are quads, or quadriceps femoris
100 points for each essential electrolyte in the human body. Essential is a loose term and doesn't need to have been in the slides
sodium, potassium, chloride, magnesium, calcium, phosphate, and more
what is the most key part of planning an offseason
RECOVERY
four most common injuries (for track)
shin splints, stress fractures, muscle strains, jumper knee/tendonitis
This American sprinter just won the 60m world championships
Christian Coleman
This is the scarring of muscle tissue and begins to occur 2 weeks after activity unless properly recovered.
What is fibrosis.
Water, H2O, oxidane
what is the impact of too high or too low volume
low volume means no impact high volume = overtraining and longer recovery
a small crack that forms in the bone due to repetitive force
Stress fractures
The greatest high school athlete to ever run the 400 meters indoors. (I high-fived him)
Short, high intensity, strength training leads to what changes in muscle?
Muscle cells becoming thicker and stronger. Muscle damage is also accepted.
These 3 macromolecule groups are main sources of energy and material for the body.
Proteins, Carbohydrates, Lipids (fats)
What can a person expect to happen to their performance if they have consistently been sleeping less than 7 hours a day for a month
their body is slowly going to run into the symptoms of overfitting as body is not fully recovering until their training hurts more than it helps.
This injury is caused by micro-tears in the connective tissue between the muscle and the shinbone
Tibialis Stress Disorder (Shin splints)
She is the most decorated track athlete in world athletics championship medals, and second in terms of Olympic medals.
Allyson Felix
Endurance training leads to what changes in muscle?
More mitochondria created in each muscle cell.
One molecule of glucose will produce around how much ATP and how long after activity
Accepting 31-39 ATP per molecule
10 seconds to 2-3 minutes.
order of energy systems used as time goes up
Phosphocreatine, anaerobic, aerobic, fats
what are the 5 main causes of muscle strains
bad warmup, Fatigue, bad form, overuse, weak
This American middle/long distance runner won a silver medal at Glasgow. He was the NCAA D1 champion in the 1500 in 2019
Yared Nuguse
Which ion binds to troponin to allow for actin and myosin filaments to bind and contract.
Calcium ion
Ca2+ for 1 bonus point/prize
This energy system creates energy almost immediately after activity begins and can provide energy for upwards of 6-8 seconds.
ATP phosphocreatine system,
ATP-PCr
Most important factor out of volume, frequency, and intensity.
Intensity
The difference between a strain and a tear
A strain is damage but not a complete tear, a tear tears the muscle.
This Czech athlete became the javelin world record holder in 1996. Bonus points for distance within 0.5 meters.
