ATHLETES: Overtraining can seriously affect performance. Researchers have identified several short term key markers that result from overtraining, including "impaired anaerobic lactic acid perforance and a reduced time to exhaustion". [ 7 ] The same study discusses many other soon-to-follow issues including problems with uric acid levels, ammonia, creatine kinase, free testosterone/cortisol, growth hormone and so on. More subjective issues include excessively sore muscles and sleep and mood disorders. Again, overtraining is real and leads to real physiological issues.
Obesity – Overweight men breasts seem too big because of fat deposits, not the growth of breast tissue. This condition is known pseudogynecomastia.
