Athletic muscle is a term used to describe the physical characteristics of an athlete's body, particularly their musculature. Athletic performance is influenced by both genetic and environmental factors, with the strength of skeletal muscles and the type of muscle fibres composing them being key determinants. Slow-twitch muscle fibres enable endurance activities like long-distance running, while fast-twitch fibres are suited for sprinting and power-intensive activities. Athletic muscle development is sport-specific, with athletes cultivating muscle shapes and sizes that match the characteristics of their sport. This includes considerations of muscle length, range of motion, and absolute strength. An athletic physique is characterised by lean muscle mass, which enhances mobility, stability, and overall athletic capabilities.

What You'll Learn
Muscle belly size
When considering muscle belly size, it is essential to determine whether hypertrophy is necessary and, if so, whether it should be myofibrillar or sarcoplasmic. Myofibrillar hypertrophy, achieved through heavy weight lifting, increases power output, while sarcoplasmic hypertrophy results in a larger muscle size without necessarily increasing strength.
To increase muscle belly size, resistance training is essential. Specific exercises such as back squats, single-leg squats, bench presses, pull-ups, and dumbbell incline benches can help develop athletic muscle and increase strength. Additionally, proper nutrition and adequate sleep are crucial for muscle growth and recovery.
Stretching is another critical component of increasing muscle belly size. By stretching the muscles during and after a workout, individuals can prevent muscle knots and tightness. Stretching also lengthens muscle fibres, promoting growth and adding visible length over time.
It is important to note that the length of muscle bellies is largely determined by genetics. While individuals can maximise their muscle length through various exercises and stretching routines, the overall length of muscle bellies can vary from person to person due to genetic factors.

Range of motion
Athletic muscle is characterised by a combination of speed, range of motion, and maximal strength. The ability to coordinate quickly and display a large amount of absolute strength is also key.
Athletic muscle is developed through a full range of motion. This means that athletes can move through a variety of ranges with great definition and specific qualities. For example, athletes can produce a large amount of force in a short space of time, and then release and move into another position with speed and accuracy.
To achieve this, athletes need to focus on movements that are executed through a full range of motion. This includes exercises such as back squats, single-leg squats, bench press, pull-ups, and sled pulls. These exercises bring about a great transfer of training, leading to more technical coordination and an increased ceiling of technical coordination movements.
The ability to move through a full range of motion is also linked to the athlete's physique. An athletic physique is not the same as a bodybuilding physique, as big, hulking muscles can interfere with sports performance. Instead, athletic muscle is lean, with less body fat, which allows for greater movement, mobility, and athletic manoeuvres.
The type of muscle fibres that compose an athlete's body also plays a role in their range of motion. There are two types of muscle fibres: slow-twitch fibres and fast-twitch fibres. Slow-twitch muscle fibres contract slowly but can work for a long time without tiring, enabling endurance activities like long-distance running. Fast-twitch muscle fibres contract quickly but tire rapidly, making them ideal for sprinting and other activities requiring power or strength.
Genetics also plays a role in an athlete's range of motion. The ACTN3 and ACE genes influence the fibre type that makes up muscles and have been linked to strength and endurance. The ACTN3 gene, for example, is predominantly found in fast-twitch muscle fibres, while a variant called R577X leads to a higher proportion of slow-twitch fibres.
By understanding the importance of range of motion and incorporating exercises that promote a full range of motion, athletes can develop the athletic muscle necessary for their chosen sport.

Muscle fibre types
Skeletal muscle fibres can be classified based on two criteria: the speed of contraction and how they regenerate adenosine triphosphate (ATP). Using these criteria, there are three main types of skeletal muscle fibres:
Slow Oxidative (Type I)
Slow oxidative fibres, also known as slow-twitch fibres, contract relatively slowly and use aerobic respiration (oxygen and glucose) to produce ATP. They produce low-power contractions over long periods and are slow to fatigue.
Fast Oxidative (Type IIa)
Fast oxidative fibres, also known as fast-twitch fibres, contract relatively quickly and primarily use aerobic respiration to generate ATP. They produce higher tension contractions than slow oxidative fibres.
Fast Glycolytic (Type IIx)
Fast glycolytic fibres use anaerobic glycolysis as their primary ATP source. They have a large diameter and possess large volumes of glycogen, which is used to generate ATP quickly. These fibres fatigue quickly and are only used for short periods. However, they enable rapid and forceful contractions associated with quick, powerful movements.
Most skeletal muscles in the human body contain all three types of muscle fibres, although the proportions vary. The speed of contraction depends on how quickly myosin's ATPase hydrolyzes ATP to produce cross-bridge action.
While knowledge of muscle fibre types and their functions is important, it is worth noting that it will not necessarily make a practical difference in athletic performance. Athletic performance is influenced by various factors, including muscular strength, speed, range of motion, coordination, and recovery. Additionally, biological factors such as age and hormone levels can affect muscle development.

Muscle architecture
Single skeletal muscle fibres are elongated, multinucleated cells with variable lengths and shapes. A muscle fibre is made up of a number of myofibrils arranged in parallel, which are in turn made up of sarcomeres arranged in series. A sarcomere is the functional unit of muscle contraction, consisting of myofilaments, namely myosin and actin. The basal lamina defines the anatomical boundary of a single fibre, and myonuclei are distributed along the length of the fibre.
There are several types of muscle architecture, including parallel, pennate, and hydrostats. Parallel muscles have fibres that are parallel to the force-generating axis, while pennate muscles can be further classified into unipennate, bipennate, and multipennate subgroups. Unipennate muscles have fibres oriented at one fibre angle to the force-generating axis and are all on the same side of a tendon, with pennation angles typically ranging from 0° to 30°. Bipennate muscles have fibres on two sides of a tendon, while multipennate muscles, such as the human deltoid muscle, have fibres oriented at multiple angles along the force-generating axis. Muscular hydrostats function independently of a hardened skeletal system.
The shape of a muscle also influences its function. Fusiform muscles, for example, are wider and cylindrically shaped in the centre, tapering off at the ends, often referred to as a spindle. The line of action in this type of muscle runs in a straight line between the attachment points, usually tendons. Due to their shape, fusiform muscles concentrate force into a small area. Convergent or triangular muscles, on the other hand, converge at one end and spread out in a fan shape at the other, allowing for a change in the direction of pull.

Lean muscle mass
Lean body mass (LBM) is a part of body composition that is defined as the difference between total body weight and body fat weight. LBM counts the mass of all organs except body fat, including bones, muscles, blood, skin, and everything else. Lean body mass is often used interchangeably with "lean muscle", but they are not the same thing. While lean body mass includes muscle mass, it also includes other components such as bones, water, ligaments, tendons, and internal organs.
Gaining muscle mass can help achieve a leaner body composition and weight loss. Muscle mass can be increased through various forms of exercise, including weight-bearing exercises, resistance training, and cardio. Resistance training, in particular, has been shown to be effective in slowing the loss of muscle mass that occurs with ageing. Additionally, sufficient protein intake is important for muscle growth and recovery.
To build athletic muscle, it is important to focus on exercises that improve speed, range of motion, and maximal strength. Movements such as back squats, single-leg squats, bench press, and pull-ups executed through full ranges of motion can help develop athletic strength. Proper nutrition, including adequate protein intake, and sufficient sleep are also crucial for building athletic muscle.
It is worth noting that simply increasing lean body mass does not necessarily indicate an increase in muscle mass. Lean body mass can fluctuate due to changes in body water content, which is a significant component of lean body mass. Therefore, when discussing "lean gains", it is important to distinguish between increases in lean body mass and skeletal muscle mass.
