Adaptability ….
Specific Adaptations to Imposed Demands (S.A.I.D.)
the body’s natural adaptive response:
homeostasis
If you stop exercising, how much is lost?
up to 50% of fitness improvements are lost within 2 months
when you stop exercising, what goes first?
CV fitness may decline in about 2 weeks, muscular later
what are tha Limits on Adaptability?
Individual Differences
how much O2 transport and use may improve?
only about 5-25% through training
the right side of the heart:
adds O2 and expels CO2 from blood
the left side of the heart:
distribute O2, nutrients, remove wastes
which systems produce lactic acid, leading to muscle fatigue?
anaerobic
Fartlek training
Incorporating relatively more intense training into a less intense training session. Use existing environmental conditions, i.e., hills and stairs, and plan the training session to include them on the running/ jogging route.
what in gender limit potential amount of growth due to training?
Hormonal differences
