Fast-twitch muscle fibers help you perform quick, explosive movements, whereas slow-twitch fibers help with slower, more powerful movements. Your muscles contain each, but in different proportions. While you can't change the amount of muscle...
Jumping rope is one of the oldest and most widely available ways to exercise because it's inexpensive and can be done just about anywhere. Best of all, jumping rope offers aerobic and anaerobic benefits to several muscles groups, including your...
Flat or round, long or short, resistance bands are available in a wide variety of styles, colors, textures and strengths. With these options available, you are sure to find one that will fit into your workout program. If you are using resistance...
Skeletal muscles are made out of bundled fibers that condense to contract the entire muscle. When the muscle contracts, it exerts a pull on the bone to which it is attached. Two types of muscle fibers in humans, known as Type I and Type II fibers,...
Skeletal muscle has both fast twitch and slow twitch fibers. The slow twitch fibers are darker from the extra hemoglobin, which provides extra energy for endurance-type activities, such as running a marathon. Fast twitch fibers are lighter and...
Your muscles contain two types of fibers: slow-twitch and fast-twitch. Slow-twitch fibers fuel aerobic exercise and contract for a long period of time, and your fast-twitch fibers contract quickly and contribute to explosive and powerful...
Your skeletal muscles help control the position and movement of your skeleton. Healthy skeletal muscle allows for proper movement and supports breathing and posture. Each skeletal muscle contains a number of muscle fibers, each of which connects...
During exercise, you use different types of muscle fibers. Fast twitch and slow twitch are the main fibers used during activity. Some people have more of one type of fiber than the other. You have the ability to increase the different muscle...
Depending on what activity you're performing, your muscles use more fast- or low-twitch muscle fibers during contractions. Fast-twitch, or phasic, muscle fibers do not use oxygen, so the process they use to create energy is anaerobic....
Muscles that control the eye must have fine motor control along with endurance, as they are rapidly firing throughout the day and night. Some muscles do not need to be as precise, but need to provide raw power and greater force. These latter...
Events in track and field require an athlete to have strong muscles in her legs. Leg presses help build and strengthen the quadriceps muscles, which help athletes to jump high and run fast. Developing starting strength and explosive power is...
The sport most often associated with a muscular physique is bodybuilding. However, a lean muscular physique also works well for many other sports. Muscles provide strength, protect joints and help you maintain endurance. Sports-targeted exercises...
"Speed kills" is a phrase used by coaches in many sports, and speed is an inherent advantage to those who possess it in the sporting arena. A speed training program is essential to athletes who participate in sports that require fast and dynamic...
Speed and strength are two of the most important qualities every athlete should posses. The muscles in your body are composed of two basic fiber types: slow twitch and fast twitch. Slow-twitch muscle fibers get their name from their speed of...
Your muscles contain three kinds of fibers known as white fast-twitch, red fast-twitch and red slow-twitch muscle fibers. Each muscle group in your body contains all three types of twitch fibers in varying degrees that are determined by your...
As you watch a track meet or running event, you'll notice two distinct body types between the sprinters and marathoners. A sprinter body is built for speed and power while the marathoner is built for long, slow endurance. But there are more...
Weight lifters use a variety of muscles in their body, from the shoulders to the feet. The muscular system is made up of two types of muscle fiber, and knowing how each plays into weight lifting can help you create workout routines that benefit...
Golf requires a combination of fast- and slow-twitch muscle fibers and muscle strength, speed and endurance to be played efficiently. While golf also requires mental strength and athletic skill, one area you can improve at home is your muscular...
Your musculature includes two types of fibers, slow twitch and fast twitch. Slow twitch muscles are recruited for endurance activities and don't tire out easily, but they can't produce as much force as fast twitch muscle fibers. Fast twitch...
Muscular fitness is commonly defined as a combination of muscular strength and muscular endurance. Muscular strength refers to your ability to exert maximal force during a limited number of repetitions, while muscular endurance refers to your...
Fast-twitch muscle fibers provide explosive power which can be helpful during sports which require sprinting, jumping and quick reaction times. Fast-twitch muscles can be grown with plyometrics, exercises that force your muscles to stretch before...
Skeletal muscles consist of two major types of muscle fibers -- fast-twitch and slow-twitch. Each muscle type is responsible for different intensity levels and exercise durations. Fast-twitch is responsible for quick reactions with a low...
Competitive sprinters require a comprehensive athletic conditioning program, which includes speed drills, plyometrics, flexibility exercise and strength training. A well-designed, sport-specific weight training program may increase bone density...
Muscular fitness is commonly defined as having two components -- strength and endurance. While muscular strength refers to the greatest amount of force exerted in a single effort, muscular endurance refers to the ability to repeat movements for an...
Muscle building usually involves resistance training like weight lifting. Various elements of your diet and exercise program contribute to maximizing muscular growth. You may undergo a period of conditioning and preliminary strengthening before...
You have different types of muscle in your body. The only type you have conscious control of are skeletal muscles, which are comprised of fast and slow twitch fibers. Each muscle has a different ratio of fast/slow twitch fibers, which is...
The calf muscles are made up of two muscles, the outer gastrocnemius and the deeper soleus. You can create two movements with the gastrocnemius: pointing the toes and bending the knee, while you use the soleus only to point the toes. The outer...
As you are watching a track meet, you may notice two types of runners – sprinters and endurance runners. The sprinters are generally lean and muscular, while the endurance runners often have a small body frame. This difference can be...
To cultivate the technique for jumping higher, you need to develop power and speed in the leg and gluteal structure while also developing core muscle stabilization. Power and speed are attributes of fast-twitch muscle fibers that are stimulated...
