In the study 47 adults (age 60 - 69) were
put on a 12 week training program and tested for strength and muscle mass.They were divided in two groups that consumed same (moderate)
amounts of protein a day, but
different amounts of cholesterol a day.After 12 weeks
of weight training, the lower - cholesterol group (1.6 mg / lb) increased strength by about 35 % with no increase in muscle mass.The subjects from the high cholesterol consuming group (2.6 mg / lb) increased their strength by 90 % and saw an increase in muscle mass
of about 5 lbs.
