Research can provide golden information to health and fitness professionals. If you’re a personal trainer, here are some recent findings to help you stay ahead of the pack:

One Egg a Day Keeps the Doctor Away

Based on the results of this meta-analysis, consumption of up to one egg daily may contribute to a decreased risk of total stroke, and daily egg intake does not appear to be associated with risk of CHD [coronary heart disease].

Note: According to Dr. Eric Serrano, concerns about whole eggs raising cholesterol levels are largely unfounded. In fact, low cholesterol levels may actually increase your risk of cancer. You can read more in My First Go Around With Dr. Eric Serrano (Part 2).

Restrict Your Calories, Restrict Your Size

These results indicate that CR [calorie restriction] attenuates resistance training-induced muscle hypertrophy, and that it may enhance mitochondrial adaptations in skeletal muscle.

Note: Alternate-day fasting provides similar benefits to moderate daily calorie restriction and may work well for some individuals — but if your goal is to build muscle, restricting calories is not the best approach.

There Are More Positives from the Negative

Eccentric training is a potent stimulus for enhancements in muscle mechanical function, and muscle-tendon unit (MTU) morphological and architectural adaptations. The inclusion of eccentric loads not constrained by concentric strength appears to be superior to traditional resistance training in improving variables associated with strength, power and speed performance.

Note: Eccentric training can catapult strength and athletic performance to a new level — if you do it right. Get the lowdown in Eccentric Training: How to Obtain Positive Results from a Negative Action.

Resistance Training: Good for the Heart and the Liver

Resistance training may help reduce systolic blood pressure levels, stroke mortality, and mortality from heart disease in people with metabolic syndrome.

Resistance exercise improves NAFLD [non-alcoholic fatty liver disease] with less energy consumption. Thus, resistance exercise may be more feasible than aerobic exercise for NAFLD patients with poor cardiorespiratory fitness or for those who cannot tolerate or participate in aerobic exercise.

RT [resistance training] as a single intervention can increase muscle strength, aerobic capacity, and QoL [quality of life] in patients with CHF [chronic heart failure] and may offer an alternative approach, particularly for those unable to participate in aerobic training.

Note: Resistance training has a profound effect on the cardiovascular system. In fact, it offers numerous benefits for heart health, liver health, and overall longevity — sometimes even surpassing aerobic exercise!

Final Thoughts

As always, it’s important to stay on top of the latest research. Use this information to inform your training approach and give your clients the best possible results.
