Lab 6 Flashcards
How did males and females in the lab compare with muscle quantity and quality
Males had more in general and better quality
Would increasing muscle size or muscle quality be more important for an Olympic weightlifter inn a lightweight category?
Increasing muscle quality would be a more important factor because you wouldn’t want to gain muscle mass and have to move up a weight class. You would want the most strength per muscle sort of for that weight class.
How do females and males differ in terms of age related strength loss in the knee extensors and knee flexors for isometric strength?
Both males and females lowered at the same rate for both knee flexors and knee extensors
-females it happened to a little earlier
How do females and males differ in terms of age related strength loss in the knee extensors and knee flexors for isokinetic (dynamic) strength?
Females would lose strength faster then males for knee flexors with a gradual loss for both male and female, but men preserve a bit longer
Aside from synthesis of new proteins, what else might account for the increase in muscle size measurement after 3 weeks of heavy strength training
Muscle swelling would also account for an increase in muscle size as heavy strength training causes damage to the fibers, causing them to swell
How do males and females differ in the satellite cell response before and after a period of resistance? Which of the sexes shows greater hypertrophy after training?
Satellite cell response would increase regardless of sex and hypertrophy of muscle would also be similar
What is muscle density? Why might this measurement be important in older adults?
Muscle density is a measure of the muscle mass in a given area in comparison to adipose tissue
-can be a measure of muscle quality
Important in older adults because they are less likely to fall if they have more muscle and a higher functional ability
