The physics of running

Running is a seemingly simple activity, but it is actually quite complex from a physics perspective. In order to run, our bodies must overcome a number of forces, including gravity, air resistance, and friction.

Gravity

Gravity is the force that pulls us towards the ground. It is constantly trying to slow us down as we run. To overcome gravity, we must push off the ground with our feet. The harder we push off the ground, the faster we will accelerate.

Air resistance

Air resistance is the force that opposes our movement through the air. It is caused by the friction between our bodies and the air molecules. Air resistance increases as we run faster. To overcome air resistance, we must streamline our bodies and run with a good cadence.

Friction

Friction is the force that opposes the movement of two surfaces in contact. It is caused by the microscopic interactions between the two surfaces. Friction between our feet and the ground is essential for running, but too much friction can slow us down. To reduce friction, we should run on a smooth surface and wear shoes with good traction.

Center of mass

Our center of mass is the point at which our entire body weight is balanced. When we run, our center of mass moves in a parabolic arc. To keep our balance, we must keep our center of mass over our feet. We do this by swinging our arms and legs in opposite directions.

Running economy

Running economy is a measure of how efficiently we use oxygen while running. A good running economy means that we can run faster for longer without getting tired. To improve our running economy, we should focus on running with a good form and avoiding wasted energy.

Other factors

Other factors that can affect our running include our weight, fitness level, and training routine. The heavier we are, the more force we need to exert to overcome gravity. The more fit we are, the more efficiently we can use oxygen. And the more we train, the better our running economy will become.

The physics of running is a complex topic, but it is important to understand if you want to improve your running performance. By understanding the forces that affect running, you can learn how to overcome them more efficiently.

Foot biomechanics while running

The foot is a complex and intricate structure that plays a vital role in running. It provides a stable base of support, absorbs impact, and propels the body forward. Understanding the biomechanics of the foot while running can help runners improve their performance and reduce the risk of injury.

The gait cycle

The gait cycle is the sequence of events that occurs when one foot takes a step and then the other. It can be divided into two phases: stance phase and swing phase.

Stance phase

The stance phase begins when the heel strikes the ground and ends when the toes leave the ground. It can be further subdivided into three stages:

  • Initial contact: This is when the heel first touches the ground. The foot rolls inward (pronation) to absorb the impact and disperse the force throughout the foot and leg.
  • Midstance: This is when the foot is flat on the ground. The arches of the foot support the body weight and the foot begins to roll outward (supination) to prepare for push-off.
  • Push-off: This is when the toes leave the ground. The foot is fully supinated and the calf muscles are activated to propel the body forward.

Swing phase

The swing phase begins when the toes leave the ground and ends when the heel strikes the ground again. During the swing phase, the foot is not in contact with the ground and is free to swing forward.

Foot biomechanics during running

The foot undergoes a number of complex movements during the running gait cycle. These movements can be divided into three main categories:

  • Pronation: Pronation is the inward rolling of the foot. It occurs during initial contact to help absorb the impact of landing.
  • Supination: Supination is the outward rolling of the foot. It occurs during midstance to prepare for push-off.
  • Arch flattening: The arches of the foot flatten during midstance to support the body weight.

Common foot injuries

Common foot injuries in runners include:

  • Shin splints: Shin splints are pain along the inner edge of the shinbone. They are caused by overuse of the muscles and tendons in the shin.
  • Stress fractures: Stress fractures are small cracks in the bones of the foot caused by repetitive stress.
  • Plantar fasciitis: Plantar fasciitis is inflammation of the plantar fascia, a thick band of tissue that runs along the bottom of the foot.
  • Achilles tendinitis: Achilles tendinitis is inflammation of the Achilles tendon, which connects the calf muscles to the heel bone.

Tips for improving foot biomechanics and reducing the risk of injury

There are a number of things runners can do to improve their foot biomechanics and reduce the risk of injury, including:

  • Wear properly fitting running shoes: Running shoes should fit snugly but comfortably. They should also provide good arch support and cushioning.
  • Run with a midfoot strike: A midfoot strike is when the foot lands on the ground midfoot first, rather than the heel or forefoot. A midfoot strike can help reduce the impact on the joints and improve running efficiency.
  • Strengthen your foot and ankle muscles: Strong foot and ankle muscles can help support the foot and reduce the risk of injury. There are a number of exercises that can be done to strengthen these muscles, such as short foot exercises, calf raises, and ankle rolls.
  • Warm up before running: A good warm-up can help prepare the body for running and reduce the risk of injury. A warm-up should include dynamic stretches, such as arm circles and leg swings, as well as some light running.
  • Cool down after running: A cool-down can help the body recover from running and reduce the risk of injury. A cool-down should include static stretches, such as holding a hamstring stretch or calf stretch for 30 seconds.

If you are experiencing any pain in your feet or ankles while running, it is important to see a doctor or physical therapist to get a diagnosis and treatment plan.

The Science of Motion While Running: 3 Gaits

Running is a complex movement that involves the coordinated action of many different muscles and joints. The science of motion while running, or running biomechanics, is the study of how these different components work together to propel us forward.

There are three main gaits, or running styles, that runners use: heel striking, midfoot striking, and forefoot striking. Each gait has its own unique biomechanical characteristics.

Heel striking is the most common running gait. In heel striking, the runner’s heel makes contact with the ground first. This is followed by a rolling motion of the foot, from the heel to the toe. Heel striking is generally considered to be the least efficient running gait, as it produces a lot of impact forces. However, it is also a relatively stable gait, which can make it a good choice for new runners or runners with injury concerns.

Midfoot striking is a more efficient running gait than heel striking. In midfoot striking, the runner’s foot makes contact with the ground with the midfoot and heel at the same time. This helps to reduce impact forces and improve running economy. Midfoot striking can be a good choice for runners who are looking to improve their speed or endurance.

Forefoot striking is the most efficient running gait, but it is also the most challenging to master. In forefoot striking, the runner’s foot makes contact with the ground with the ball of the foot or the toes first. This gait produces the least amount of impact forces, but it also requires a lot of strength and flexibility in the ankles and calves. Forefoot striking can be a good choice for experienced runners who are looking to improve their speed or endurance.

Science of motion while running: 3 gaits

The science of motion while running can be used to explain the biomechanical differences between the three gaits.

Heel striking

When heel striking, the runner’s foot makes contact with the ground with the heel first. This causes a large impact force to travel up the leg and into the spine. Heel striking also tends to produce a longer stride length, as the runner’s foot has to travel further to reach the ground.

Midfoot striking

When midfoot striking, the runner’s foot makes contact with the ground with the midfoot and heel at the same time. This helps to reduce impact forces and improve running economy. Midfoot striking also tends to produce a shorter stride length, as the runner’s foot doesn’t have to travel as far to reach the ground.

Forefoot striking

When forefoot striking, the runner’s foot makes contact with the ground with the ball of the foot or the toes first. This produces the least amount of impact forces, but it also requires a lot of strength and flexibility in the ankles and calves. Forefoot striking also tends to produce the shortest stride length, as the runner’s foot doesn’t have to travel as far to reach the ground.

Which gait is best for you?

The best gait for you depends on a number of factors, including your running experience, fitness level, and injury history. If you are a new runner, or if you have injury concerns, it is generally recommended that you start with heel striking. Once you have gained some experience and improved your fitness, you can experiment with midfoot striking and forefoot striking to see what works best for you.

It is important to note that there is no one-size-fits-all answer to the question of which gait is best. The most important thing is to find a gait that feels comfortable and allows you to run efficiently and injury-free.

How to improve your running gait

If you are interested in improving your running gait, there are a few things you can do:

  • Start slowly. If you are new to midfoot or forefoot striking, start by gradually transitioning to the new gait. You can do this by running short distances with the new gait, and then gradually increasing the distance and speed over time.
  • Focus on your form. When running with a new gait, it is important to focus on your form. Make sure that you are landing with your foot directly below your body, and that you are not overstriding.
  • Strengthen your ankles and calves. Midfoot and forefoot striking require strong ankles and calves. You can strengthen these muscles by doing exercises such as calf raises and ankle circles.

If you are unsure how to improve your running gait, it is a good idea to consult with a running coach or physical therapist.

Shoe selection for runners

Choosing the right running shoes is essential for preventing injuries and improving your performance. With so many different shoes on the market, it can be tough to know where to start. This blog post will provide you with some tips on how to choose the best running shoes for your individual needs.

Factors to consider when choosing running shoes

  • Your foot type: Are you flat-footed, high-arched, or somewhere in between? Knowing your foot type will help you choose shoes with the right amount of support and cushioning.
  • Your running style: Do you heel strike, forefoot strike, or midfoot strike? Your running style will also influence the type of shoes you need.
  • The terrain you run on: Do you run on roads, trails, or a mix of both? Shoes designed for different types of surfaces offer different levels of traction and support.
  • Your training goals: Are you training for a marathon or just trying to get in shape? If you have specific training goals, you may want to choose shoes that are designed for those types of runs.

Different types of running shoes

There are many different types of running shoes available, each with its own unique features and benefits. Some of the most common types of running shoes include:

  • All-around shoes: These shoes are designed for a variety of running activities, from easy runs to tempo workouts. They offer a good balance of cushioning, support, and flexibility.
  • Stability shoes: These shoes are designed for runners who need extra support to prevent overpronation (when the foot rolls inward too much). They typically have a firmer midsole and a medial post to help guide the foot through the gait cycle.
  • Cushioned shoes: These shoes are designed for runners who want maximum cushioning. They typically have a soft midsole that absorbs impact and protects the joints.
  • Lightweight shoes: These shoes are designed for runners who want the lightest possible shoes. They typically have a thinner midsole and upper, but they may not offer as much cushioning and support as other types of shoes.
  • Trail running shoes: These shoes are designed for running on trails and other off-road surfaces. They typically have a more aggressive outsole for better traction and a more durable upper to protect the foot from debris.

How to fit running shoes

When trying on running shoes, it is important to get a good fit. The shoes should be snug but not too tight. You should have enough room to wiggle your toes and your heel should not slip. It is also important to try on shoes at the end of the day, when your feet are at their largest.

Here are some additional tips for choosing running shoes:

  • Go to a specialty running store: The staff at a specialty running store can help you assess your foot type, running style, and training goals to find the best shoes for you.
  • Try on multiple pairs of shoes: Don’t be afraid to try on multiple pairs of shoes until you find a pair that feels good.
  • Break in your new shoes gradually: Start by wearing your new shoes for short walks or runs and gradually increase the distance as your feet get used to them.

Choosing the right running shoes is an important decision. By considering your foot type, running style, the terrain you run on, and your training goals, you can find the best shoes for your individual needs.

Why you should not run fast ?

Pace is a very important metric for runners, especially for those who are training for a specific race or distance. However, it’s also important to know when to stay away from pace. Here are a few reasons why:

  • It can lead to injury. If you’re always running at a fast pace, you’re putting your body at a higher risk of injury. This is because your muscles and joints don’t have enough time to recover between workouts.
  • It can burnout. Running at a fast pace all the time can also lead to burnout. This is when you become physically and mentally exhausted from running too hard. Burnout can make it difficult to stick to your training plan and can even lead to you giving up on running altogether.
  • It can take the fun out of running. If you’re constantly focused on your pace, you’re missing out on the enjoyment of running. Running should be something that you enjoy, not something that you dread.

So, when should you stay away from pace? Here are a few tips:

  • On long runs. Your long run should be done at a conversational pace. This means that you should be able to talk in complete sentences while running. If you can’t talk, you’re running too fast.
  • On recovery runs. Recovery runs should be done at a very slow pace. These runs are meant to help your body recover from harder workouts. Don’t worry about your pace on recovery runs. Just focus on listening to your body and running at a pace that feels comfortable.
  • When you’re not feeling well. If you’re feeling tired, sick, or injured, don’t worry about your pace. Just focus on running at a pace that feels comfortable and that won’t make your symptoms worse.
  • When you’re just out for fun. If you’re just out for a fun run, don’t worry about your pace at all. Just enjoy the run and focus on the scenery or the company you’re with.

Here are a few tips for running without pace:

  • Listen to your body. Pay attention to how you’re feeling and adjust your pace accordingly. If you’re feeling tired, slow down. If you’re feeling good, you can speed up.
  • Run to feel, not to a number. Instead of focusing on your pace, focus on how you feel. Are you breathing comfortably? Are your muscles feeling good? If so, you’re at a good pace.
  • Run with friends. Running with friends is a great way to take your mind off of your pace and focus on enjoying the run. You can chat with your friends or simply enjoy each other’s company.
  • Run on new routes. Running on new routes is another great way to take your mind off of your pace and focus on the scenery. You can explore your neighborhood or city or even run in a park or nature preserve.

Remember, pace is not the most important thing when it comes to running. The most important thing is to enjoy yourself and to listen to your body.

Heart rate base training for runners: Why it’s important and how to do it

Heart rate base training is a type of training that uses your heart rate to monitor your intensity and ensure that you are training in the right zones. It is a very effective way to improve your running performance, reduce your risk of injury, and avoid overtraining.

Why is heart rate base training important for runners?

Your heart rate is a good indicator of how hard you are working. When you run, your heart rate increases to meet the increased demand for oxygen. By monitoring your heart rate, you can ensure that you are running at the right intensity for your goals.

There are five main heart rate zones:

  • Zone 1: Very easy effort, conversational pace
  • Zone 2: Easy effort, slightly harder than conversational pace
  • Zone 3: Moderate effort, feeling like you are working but can still talk in complete sentences
  • Zone 4: Hard effort, breathing heavier and can only talk in short phrases
  • Zone 5: Very hard effort, breathing very hard and can only talk in a few words

Each heart rate zone is associated with different physiological benefits. For example, running in Zone 2 helps to build your aerobic base, while running in Zone 4 helps to improve your speed and lactate threshold.

Benefits of heart rate base training for runners

Heart rate base training has many benefits for runners, including:

  • Improved running performance: Heart rate base training helps you to train in the right zones to improve your aerobic capacity, speed, and lactate threshold. This can lead to faster race times and improved running performance overall.
  • Reduced risk of injury: Heart rate base training can help you to avoid overtraining and reduce your risk of injury. When you overtrain, your body does not have enough time to recover, which can lead to injuries such as stress fractures and overuse injuries.
  • Improved recovery: Heart rate base training can help you to recover more quickly from workouts and races. This is because it helps to keep your heart rate in a manageable zone, which reduces the amount of stress on your body.

How to do heart rate base training

To do heart rate base training, you will need a heart rate monitor. There are many different types of heart rate monitors available, so you can choose one that fits your budget and needs.

Once you have a heart rate monitor, you need to determine your heart rate zones. There are a few different ways to do this, but the most common method is to use the Karvonen formula:

Max heart rate = 220 - age
Resting heart rate = (heart rate when you first wake up in the morning)
Heart rate reserve = max heart rate - resting heart rate

Zone 1: 50-60% of heart rate reserve
Zone 2: 60-70% of heart rate reserve
Zone 3: 70-80% of heart rate reserve
Zone 4: 80-90% of heart rate reserve
Zone 5: 90-100% of heart rate reserve

Once you know your heart rate zones, you can start to plan your workouts. A typical heart rate base training plan will include a mix of easy runs, tempo runs, and interval workouts.

  • Easy runs: Easy runs should be done in Zone 1 or Zone 2. These runs should be conversational paced and should help you to build your aerobic base.
  • Tempo runs: Tempo runs should be done in Zone 3. These runs are slightly harder than easy runs and help to improve your speed and lactate threshold.
  • Interval workouts: Interval workouts involve alternating between periods of hard running and periods of easy running or recovery. Interval workouts can be done in any heart rate zone, but they are typically done in Zone 4 or Zone 5.

Tips for heart rate base training

Here are a few tips for heart rate base training:

  • Start slowly and gradually increase the intensity and duration of your workouts over time.
  • Listen to your body and don’t push yourself too hard.
  • Make sure to warm up properly before each workout and cool down afterwards.
  • Stay hydrated and eat a healthy diet.

Heart rate base training is a great way to improve your running performance and reduce your risk of injury. If you are serious about running, I encourage you to give it a try.
