Muscle pretension is the stimulation of muscles to contract in preparation for an exercise. It is a way to prime the muscles to be ready to go before a workout or race. This can be done by doing a short plyometric or weight session 1-2 days before the race, or 2-3 exercises during the warm-up. Preloading the muscle allows more time for it to form cross-bridges for optimal strength. The key is to find ways to lower the tension on easy days to promote recovery and increase it before competitions and hard sessions.

What You'll Learn
Running on hard surfaces like concrete increases muscle tension
Running is a great form of exercise, but it can be hard on your body, especially if you're pounding the pavement on a hard surface like concrete. Running on concrete increases the tension in your muscles and can lead to various health issues and injuries.
When you run on concrete, the impact of each step generates higher mean and peak total accelerations compared to softer surfaces like synthetic tracks or grass. This means that your legs are subjected to greater biomechanical loads, which can result in increased muscle tension. The high impact forces on concrete can cause repeated stress on the bones of your feet and legs, potentially leading to stress fractures, which are painful and take a long time to heal. It is common for regular concrete runners to experience pain in their hips, knees, and ankles, which may increase the risk of developing arthritis and cause persistent joint discomfort.
To reduce the risk of injuries and muscle tension associated with running on concrete, it is recommended to vary your running surfaces. Include softer surfaces like gravel paths, dirt trails, and grass in your running routine. By doing so, you can decrease the overall impact forces on your body and reduce the chances of overuse injuries. Additionally, choosing a sturdy and comfortable pair of running shoes can help correct your posture and walking style, further reducing the risk of injuries and muscle tension.
While running on hard surfaces like concrete can increase muscle tension, it is important to note that muscle tension itself is not always negative. Muscle tension refers to the stored energy in your muscles, and having some tension can be beneficial for runners. With the right amount of tension, you can run more economically, storing and returning energy efficiently with each stride. This can help you race faster and improve your performance.
To summarize, while running on hard surfaces like concrete does increase muscle tension, incorporating varied running surfaces and proper footwear into your routine can help mitigate the negative impacts. Additionally, understanding how to manipulate muscle tension through training can be a powerful tool to enhance your running performance and achieve your best race times.

Preloading muscles before a workout increases strength
Preloading or pre-tensioning your muscles before a workout is a technique that can help increase strength and improve performance. It involves stimulating a muscle to contract in order to resist or control a weight before the actual exercise begins. This can be done, for example, by holding a dumbbell in the start position of a bicep curl, so your biceps are firing and prepared to lift the weight, allowing you to apply near-maximal force when beginning the curl.
Preloading is particularly important when using machines and cables, as these are designed to start exercises with zero resistance. To avoid neglecting to preload, apply some force to the machine or cable and lift the weight slightly before starting your exercise. It is also important not to lower the weight all the way during the exercise, as this will ensure your muscles remain activated and prepared for the next repetition.
The benefits of preloading are also seen in free weight exercises, which naturally incorporate a degree of preloading. For example, when performing a deadlift or power clean, assume the start position and apply force to the bar before exploding into the movement. This technique allows the muscle more time to form cross-bridges within each muscle fibre, pre-setting to shorten the fibre when contracted, resulting in optimal strength.
Plyometric exercises are another way to preload muscles, exploiting the stretch-shortening cycle to generate maximum force in minimum time. This involves "prestretching" a muscle before a concentric action to enhance force production during the subsequent muscle action.
Research has also shown the benefits of preloading for older adults, with muscular pretension having a strong influence on strength measurement. Additionally, a minimal pretension of 10% can help to prevent injuries or measuring errors.

Muscle tension is essential for performance
Furthermore, maintaining muscle tension is essential for strength and growth. This can be achieved through exercises such as weighted crunches, dynamic stretches, and underwater resistance training. Pre-tensioning, or inducing tension prior to an action, has been shown to be beneficial in preventing injuries and measuring errors, especially in older adults.
The effects of pre-tension on muscle performance have been studied in various contexts, including elbow flexion and knee extensor and flexor muscles. These studies have found that pre-tension influences strength measurements and power output. Additionally, the time a muscle is under tension is a key factor in hypertrophy, with slower lifting movements leading to greater increases in muscle protein synthesis compared to rapid movements.
Overall, muscle tension plays a critical role in performance by enhancing strength, growth, and muscle protein synthesis. By incorporating resistance exercises, maintaining tension through various workouts, and utilising pre-tensioning techniques, individuals can improve their physical performance and achieve their fitness goals.

Muscle pretension can be beneficial for older adults
Muscle pretension, or pre-activation, is a technique used to enhance muscle performance and improve strength measurements, particularly in older adults. It involves generating tension in a muscle before a contraction or movement, which can lead to increased force production and improved muscle function.
For older adults, the benefits of muscle pretension can be significant. As we age, there is a natural decline in muscle mass, strength, and physical stamina. This can lead to a condition called sarcopenia, which is characterised by muscle loss and a subsequent reduction in strength and function. However, muscle pretension, when incorporated into strength and resistance training routines, can help mitigate these effects.
Studies have shown that muscle pretension can influence strength measurements, particularly in the knee extensor and flexor muscles. This is important for older adults as it can help identify potential fall risks and prevent injuries. Additionally, muscle pretension can improve the reliability of strength measurements, reducing errors, and allowing for more accurate assessments of muscle function in older adults.
To achieve optimal results, a minimal level of pretension, around 10%, is recommended. This helps prevent injuries and measurement errors, ensuring a suitable standard for older adults. Higher levels of pretension may lead to a lower maximum rate of torque development, so it is essential to tailor the pretension level to the individual's needs and abilities.
Overall, muscle pretension can play a beneficial role in the health and well-being of older adults. When combined with strength and resistance training, it can help improve muscle function, balance, and overall physical performance, leading to a more active and independent lifestyle as we age.

Ice baths after a workout can increase muscle tension
Ice baths, also known as cold-water immersion or cryotherapy, are a common practice among athletes to reduce muscle pain and soreness after intense training sessions or competitions. The cold temperature of an ice bath, typically at 12–15°C, is believed to bring down the metabolism, causing a slowdown in breathing and sweating. This, in turn, helps reduce swelling and tissue breakdown, which can aid in muscle recovery.
The theory behind ice baths is that intense exercise causes microtrauma or tiny tears in muscle fibers. This microscopic muscle damage stimulates cell activity and repairs damage, strengthening and rebuilding the muscles. The cold temperature of an ice bath can also cause constriction of blood vessels, which helps flush out waste products such as lactic acid from the affected tissue.
While the research on the effectiveness of ice baths is mixed, many athletes swear by them as a way to recover faster, prevent injury, and feel better. It is recommended that if you are considering taking an ice bath, you should do so 24 to 48 hours after your training session to allow time for the necessary inflammatory process. It is also important to use ice baths with caution and to always have someone else present in case of an unexpected reaction.
It is worth noting that exposure to cold temperatures may result in hypothermia and can affect your blood pressure, circulation, and heart rate. Therefore, it is always advisable to consult a healthcare practitioner before practicing an ice bath and to remove yourself from the cold water if you experience any negative symptoms.
