Speed is derived from a combination of muscle strength, shortening speed, cross-sectional area, pennation, sarcomere length, myosin isoforms, and neural activation of motor units. The muscles used to achieve speed depend on the type of movement, such as sprinting or endurance running. For example, fast-twitch muscle fibres are used for sprinting and weight-lifting, while slow-twitch muscle fibres are used for endurance running. Additionally, the hip, leg, and ankle muscles are essential for increasing speed while running, especially when running downhill or uphill.

Running downhill requires more effort from your hip, leg, and ankle muscles
Running is a whole-body workout, but it primarily engages your core and the muscles of your hips, glutes, quadriceps, hamstrings, and calves. The degree of muscle engagement depends on your speed and terrain.
Running downhill is easier on your cardiac muscles, but your hip, leg, and ankle muscles must work harder, especially your hip extensors, quads, and knees. This is because, when running downhill, you naturally use more of a heel-foot strike, which helps to slow down your forward movement. This can cause an added force of gravity on your muscles and joints when you land, leading to muscle damage as the eccentric contractions, or elongating of your muscle fibres, stretch under tension to help your body stay in control with each step.
To avoid putting too much pressure on your shinbones, which can lead to shin splints, be mindful not to lean your upper body too far back. Instead, lean forward from the ankle and not the hip. Keep your torso upright, engage your core, and avoid slouching or leaning too far forward or backward. Focus your gaze on the road or trail ahead rather than looking down at your feet. This helps you maintain balance and anticipate the terrain.
To strengthen your hip, leg, and ankle muscles for downhill running, you can try the following exercise: Using one leg at a time, step down from a low height (no more than a six-inch step or the bottom step of your stairs) to the floor with one foot, tap the floor with your heel, then return to the starting position. Continue doing this for 10 reps, then alternate the starting leg, and repeat for three rounds total. This exercise mimics the action of your stride moving downhill and will help develop powerful quads for stronger hill climbing. It will also help with ankle stability.

Running with weights increases calorie burn and heart rate but may not build resistance
Running is a whole-body workout that primarily engages the core and lower body muscles, including the hamstrings, calves, hips, glutes, quadriceps, and tendons and ligaments. To increase speed, it is important to strengthen these muscles through exercises such as leg lifts, knee drives, and hamstring swings.
Running with weights is an effective way to increase calorie burn and get the heart pumping. It can also help increase speed. However, it may not be the best method for building resistance. While running with weights can be a great way to burn calories and improve cardiovascular health, other forms of exercise may be more effective for building resistance and muscle mass.
Resistance and weight training are known to be more effective than cardio at building lean muscle. By increasing muscle mass, the body burns more calories at rest, leading to a higher basal metabolic rate. This means that even after a weight training session, the body continues to burn calories at a higher rate for up to 48 hours, according to a 2018 study.
To build resistance and increase muscle mass, strength training exercises that target the core and leg muscles are essential. This can include drills with resistance bands or exercises that focus on the hamstrings, such as butt kicks. By incorporating these exercises into a training program, runners can develop the leg muscles necessary to increase speed.
In conclusion, while running with weights can increase calorie burn and heart rate, it may not be the most efficient method for building resistance. To effectively build resistance and increase speed, runners should incorporate strength training exercises that target the key muscles used in running.

Sprinting and weight-lifting are best suited for fast-twitch fibres
Muscle fibres are broadly classified into two types: slow-twitch (Type I) and fast-twitch (Type II). Slow-twitch fibres are designed for endurance and slow muscle contractions, whereas fast-twitch fibres are built for quick, powerful movements.
Fast-twitch fibres are further divided into Type IIa and Type IIb. Type IIa fibres, or intermediate muscle fibres, can be used for longer periods as they take longer to fatigue. Type IIx fibres, on the other hand, are better at providing force but fatigue much faster.
Sprinting and weightlifting are high-intensity activities that rely on fast-twitch muscle fibres. These fibres contract faster, allowing them to produce greater amounts of force, power, and strength. Elite sprinters are known to have well-developed biceps femoris, one of the muscles in the hamstring group.
To strengthen and build fast-twitch muscle fibres, sprinting, powerlifting, and resistance training with maximum repetition and weight are recommended. For those who are not sprinters or weightlifters, training fast-twitch fibres can still be beneficial for performing quick, explosive movements in everyday life, such as jumping out of the way of a bicycle or catching oneself during a fall.
Plyometric exercises such as box jumps and burpees, as well as resistance training with lighter weights at faster velocities, can also help to train fast-twitch muscle fibres.

Stride length and stride frequency are key to increasing running speed
Running faster involves a combination of factors, including muscular strength, endurance, form, and technique. Increasing stride length and frequency are key mechanical aspects that can significantly impact running speed.
Stride Length and Frequency
The two main ways to increase running speed are by increasing stride rate (frequency) or length. Stride frequency refers to the number of steps taken per minute, also known as cadence. The average recreational runner has a cadence of about 150-170 steps per minute, while faster runners tend to have a cadence between 165 and 185 steps per minute.
Increasing stride frequency requires improving aerobic capacity and undergoing progressive neuromuscular training to move your legs faster. It also involves modifications to your running form, as simply moving your legs faster is a skill that demands more than just speed.
On the other hand, increasing stride length is about generating power and transferring it into forward movement. This can be achieved by increasing overall muscular strength and the power-to-weight ratio. Focusing on core strength development is crucial, as a strong core enables better energy transfer and helps maintain spinal alignment and stability.
Muscles for Speed
Running is a whole-body workout, but it primarily engages the core and lower body muscles, including the hips, glutes, quadriceps, hamstrings, and calves. Strengthening these muscles through exercises such as leg lifts, knee drives, and hamstring swings can enhance running speed. Additionally, exercises like box jumps and lunges can improve endurance and strength.
It is worth noting that flexibility also plays a role in increasing stride length. Maintaining an optimal level of flexibility ensures a good range of motion and muscle responsiveness. Dynamic warm-ups, myofascial release with a massage gun or foam roller, and running drills can help improve flexibility and, consequently, stride length.
Individual Variations
While increasing stride length and frequency are essential, it is important to recognize that each runner is unique. What works for one runner may not be the best approach for another. Understanding your individual performance and characteristics is crucial to determine where to direct your efforts. For example, if your step length is low, you may need to focus on strength and power work, while a low step frequency may indicate the need for cadence or neuromuscular work.
Additionally, factors such as height, leg length, and individual height do not solely determine natural stride frequency. Elite runners excel by developing a running form that suits their unique characteristics, and it is essential to find what works best for you.

Strengthening muscles may not be enough to increase speed
Speed is influenced by several factors, including muscle strength, elasticity, and running technique. While strengthening muscles is important, it may not be sufficient to increase speed, as other factors come into play.
Muscle strength is indeed crucial for speed, and specific exercises can enhance it. For example, exercises targeting the legs, quadriceps, glutes, and hamstrings can improve running speed. Additionally, core strength is essential, as it aids in stability, proper form, and spinal alignment, all of which contribute to optimal performance.
However, strengthening muscles alone may not be enough to significantly increase speed. Running technique, for instance, plays a significant role in speed. Proper form, such as maintaining a good posture and engaging the right muscles during a sprint, can contribute to faster times. Additionally, muscle elasticity is vital. Exercises that improve elasticity and reduce stiffness can enhance speed by allowing for more fluid and efficient movements.
Furthermore, other factors beyond muscle strengthening can influence speed. For example, cardiorespiratory endurance, which measures the performance of the heart, lungs, and muscles during physical activity, can impact speed and stamina. Additionally, factors like rest and recovery between workouts, nutrition, and overall fitness levels can also play a role in speed development.
To increase speed effectively, a well-rounded approach is necessary. This includes incorporating various exercises that target muscle strength, endurance, and elasticity, as well as focusing on running technique and overall fitness. By addressing these multiple facets, individuals can maximise their potential for speed improvement.
In conclusion, while strengthening muscles is crucial, it is just one piece of the puzzle when it comes to increasing speed. A comprehensive training program that considers multiple factors and incorporates a variety of exercises will yield the best results for individuals seeking to improve their speed performance.

Frequently asked questions
The key muscles that contribute to speed are the hip, leg, and ankle muscles. Specifically, the hip extensors, quads, knees, and hamstrings. The biceps femoris, one of the muscles in the hamstring group, is also key, with elite sprinters having a well-developed biceps femoris.
To increase speed, you need to train your muscles to express force in a shorter window of time. This is known as rate of force development (RFD). The stiffer your tendons, the more force they can produce, so this is also something to focus on.
Running downhill is easier on your cardiac muscles, but your hip, leg, and ankle muscles must work harder. Running downhill may cause you to put too much pressure on your shinbones, which can lead to shin splints.
