![]() ![]() It’s important to listen to your body and what it needs. Other weeks, you may need to take a couple days fully off, and that’s fine, too. ![]() Recovery looks different for everyone, and may even look different for you depending on how you’re feeling.įor example, one week you may do some active recovery exercises including cycling, swimming, or yoga - all of which help maintain range of motion in your joints but give your body time to heal and rebuild. On the days following your interval training, make sure to give your body a break. The International Society of Sports Nutrition (ISSN) recommends that athletes consume 1.4-2 grams of protein per kilogram of body weight per day for building and maintaining muscle mass.Īnd don’t forget about recovery. Consuming enough protein is particularly important. In order to build muscle anywhere in your body, it’s imperative that you’re consistent with both your training and diet. The study authors concluded that cardio (think exercises like cycling or running) can be effective for building muscle size when structured appropriately, especially when HIIT workouts are introduced. A control group who did not participate in the running protocol reported no significant changes, comparatively. A 2017 study in the International Journal of Exercise Science found that runners who participated in high-intensity interval training (HIIT) not only improved their cardiorespiratory fitness, but the size of their quadriceps increased, too.Īfter participating in a 10-week interval-training program, researchers found that the participants' quadriceps increased in size by 10 percent. Sprint intervals can be effective in building muscular power, especially. Meanwhile, introducing a strength-training program before adding in tempo runs and intervals is key for muscle hypertrophy, power, maintenance, and injury prevention.Īs a result of the programming, leg strength can be developed in the main lower body muscles:ĭid you know that building leg muscles also can help your run performance? After you establish a robust endurance base and introduce a strength-training plan, you can then start adding in speed sessions to your training plan to further improve your fitness and leg strength. After all, your body will adapt to the current load, meaning your run performance won’t improve until you begin to increase the intensity, volume and frequency of your runs. That’s why it’s important to stick to one of the main components of the overload principle: gradually introduce fresh challenges to encourage the ongoing strengthening in your muscles. This could be the difference between a healthy training cycle and getting injured - right from the get-go. It’s important to begin with a series of low-intensity runs before introducing speed workouts to ensure your body can withstand the added impact that’s incurred when you do speed workouts. To do so, start by running a handful of times at a comfortable pace several days a week, if possible. Typically in a beginner’s running program, the first focus will be on developing a strong base line or endurance. ![]() Depending on your goals, you may emphasize strengthening one type of muscle fiber over another. All of the muscles in your legs contain a mix of both types of muscle fibers, so your training program should, ideally, include both endurance runs and powerful speed sessions to build strength and increase your fitness. But when you do something a bit quicker, like sprint intervals, your fast-twitch muscle fibers are recruited. What does this mean for your runs and strengthening your leg muscles? When you go for a long run, your slow-twitch muscle fibers help to sustain your pace throughout the miles. Slow-twitch muscle fibers are resistant to fatigue and produce a low and slow force, whereas fast-twitch muscles fatigue a bit more easily, producing a powerful, quicker force. For context, there are two main types of skeletal muscle fibers: slow twitch and fast twitch. Depending on the type of stress, like sprints versus a long run, you can further enhance the type of muscle fibers that respond to the stimulus. MPS happens during recovery, and with the help of proper nutrition.Īnd it doesn’t just stop there. Then, the healing process, known as muscle protein synthesis (MPS) leads to the reaction of the muscle fibers to grow back stronger. The stressor causes a breakdown in muscle fibers called muscle protein breakdown (MPB). In order to build muscle, you need to expose your body to a new and challenging stimulus, according to the overload principle. ![]()
