muscle fiber
It’s not surprising that we lose muscle strength and size with age – but did you know the muscle fiber composition of your muscle fibers change to? Find out how these changes occur and why you need more power training.
After a strength-training workout, your muscles are fatigued and need rest and recovery time. Giving your muscles the right recovery environment is important for muscle growth and for strength gains. Find out how your muscles repair and how it relates to muscle hypertrophy and strength.
You have two main types of muscle fibers – those adapted to strength and power and those best suited for endurance activities. You’re born with a certain ratio of these fibers, and the ratio you have may be a factor in how strong you are or how much endurance you have – but are these fibers “fixed” or can you change the ratio through training? Find out what research shows.
Body composition changes with age. One of those changes is a decrease in lean body mass. Have you ever thought about why muscles age and whether there are things you can do to slow down this process? This article discusses research looking at how muscles age.
Ever wonder what’s going on behind the scenes when you resistance train? There are a number of hormones at work that have an impact on muscle growth. Find out more about these key players and how they make it harder or easier to build lean body mass.
To build lean body mass, you have to progressively overload your muscles. When it comes down to it, there are three factors that impact muscle development and you can control these factors by the amount of weight you lift, the volume of your workout and the time you rest between sets. Find out more about these three factors and how to use them to maximize your workout.
Do you have a higher ratio of more powerful fast-twitch muscle fibers or more slow-twitch muscle fibers designed for endurance activities like long distance running?
Find out why some people are exercise non-responders and why some forms of exercise may be better for some people than others.
