Short-duration; high resistance training

Main effect on white fibers

Results: Hypertrophy: increases

sarcotubule system RNA, DNA, nuclei Glycogen Creatine phosphate

Long-duration; low intensity training

Main effect on red fibers

results:

Increased fatigue resistance due to increases in:

Number & activity of mitochondria

Expression of oxidative enzymes

Myoglobin content Capillary density Fat stores and
