Difference between Muscular Hypertorophy and Muscular Strength and the Importance of Each

A common question we trainers often get asked is what is the difference between hypertrophy and strength and why is it necessary to work on both? Hypertrophy simply put is the increase of muscle fiber size. Muscle hypertrophy should not be confused with muscle hyperplasia, which is an increase in the number of muscle fibers. Muscle hyperplasia is thought to cease at an early on during development. The increase in muscle tone one undergoes through resistance training comes primarily from hypertrophy, or the increase in muscle fiber size one already had. Strength is how much force that specific muscle or a muscle group can exert in a single effort.

Muscle Groups and Training

By Garrett Giles

To understand muscle groups and how training certain muscle groups can be advantageous to your workout and increase efficiency, we must first understand muscle contraction and muscle recruitment. Skeletal muscle is made up of very small contractile units. There are two types of units: thick filament called myosin and thin filament called actin. These filament slide over each other thus causing a muscular contraction. Myosin has finger like structures that grab onto the actin, and then pulls the actin to cause a contraction. In order for the myosin to attach on the actin a few other processes must happen first. First, an action potential, also called a nerve impulse, is sent to the muscle via the T- tubules, which then releases calcium from the Sarcoplasmic Reticulum. The calcium then binds onto a structure which sits on the actin called troponin. Once calcium is attached to the troponin, tropomyosin, which acts like a cover keeping myosin from attaching, moves allowing myosin to complete the cross-bridge and grab ahold of the actin to then perform a muscle contraction.

Body Composition Measurements and Why They May Not Be That Important

By Dr. Marc Luko

With the start of a new year comes new fad diets, weight loss programs, and sparked interest in “finally using that exercise bike I bought two years ago.” As a strength and conditioning coach, I am all about individuals meeting their health and fitness goals. With that said, I find that there are some out there that may be looking at the wrong metrics when it comes to determining whether or not they are “fit”, or, losing fat.

You Can (& Should) Still Exercise While on (holiday) Travel

Millions of Americans, more than a few in Washington DC are packing their bags and making travel plans home to spend Christmas with family; maybe you’re among them, and maybe you’re looking forward to a few days to rest, recharge, and relax.

Enjoy. You’ve earned it! But don’t let that hard work end now. Plan to eat a healthy breakfast; avoid excessive alcohol consumption; take a small piece of pie, or say no to dessert altogether; and always, always stick to your exercise routine.
