Skipping Breakfast Results
In Higher Daily Caloric Intake
Many American women skip breakfast, either due to lack of time or a desire to lose weight. The purpose of this study was to determine how eating breakfast affects energy intake, energy expenditure, and circulating insulin, glucose, and lipid concentrations in healthy women. Ten women with normal BMIs were subjects. Each woman ate breakfast every morning for 2 weeks and then skipped breakfast every day for 2 weeks.
The women
were tested before and after each period. The results showed that skipping
breakfast resulted in a greater overall daily calorie intake,
higher total and LDL cholesterol concentrations, and somewhat greater
insulin resistance.
The results of this study indicate that omitting breakfast causes metabolic
shifts in insulin sensitivity that result in greater food consumption,
higher cholesterol concentrations, and a greater risk for
weight gain. Fitness Professionals are encouraged to share
this information with their clients to educate them about the importance
of eating breakfast daily.
Eccentric
Muscle Strength
Maintained Even Without Training
It is well documented that resistance training increases strength during maximal eccentric muscle contraction. The goal of this study was to examine the effect of detraining on changes in maximal muscle strength.
Thirteen young, sedentary men were subjects. Maximal knee extensor strength was measured before and after 3 months of heavy resistance training. Knee extensor strength was measured again after 3 months without training.
The researchers found that after 3 months of training, significant increases in both eccentric and concentric muscle strength were noted, along with increases in the cross-sectional area. Following 3 months without training, however, the researchers found that maximal muscle strength was maintained during eccentric, but not concentric, contraction. The results of this study indicate that heavy resistance training results in longer-lasting gains in eccentric strength which may be helpful for clients who must interrupt their training for a short time.

Need CEs?
Why Not Double Dip With Exercise ETC?
Many
Fitness Professionals now have multiple national certifications they need
to keep current, so why waste your time and money with CE programs that
are only approved by one or two organizations? Since Exercise ETC continuing
education programs are approved or accepted by virtually all major Certifying
Organizations, Exercise ETC CEs can be used for virtually all of your
re-certification needs! Choose from either “live” programs
or correspondence education programs. Visit our web site for details at:
