![]() ![]() In fact, by accomplishing this you decrease lactate production 1 at all exercise intensities. Developing Muscular Endurance & Racing Faster, LongerĪs you develop a high level of muscular endurance you train your muscles to resist fatigue and to elevate your lactate threshold. Here is where developing muscular endurance comes into play. If this blood is delivered to poorly trained muscles, performance will be low despite having a high aerobic capacity or “big engine”. Long distance training at an easy effort builds your heart’s capacity to pump more oxygen-rich blood to your working muscles. Your central system supplies the oxygen-rich blood your peripheral system needs in order to do the work you are demanding of it. You should view your heart and lungs as your body’s central system and your muscles as your body’s peripheral system. This is the pace and intensity where you need your muscles at peak resistance to fatigue. A moderately fast speed is the pace and intensity where most athletes race endurance events like a triathlon. This is not a slow easy pace, but it is also not an all-out max effort. It is another to perform for a moderately long time at a moderately high pace or intensity. Here’s the thing: It is one thing to be able to perform for a long period of time at a slow pace or intensity. You can move from exercise to exercise every 30 to 60 seconds to create endurance workouts, or perform one movement, such as jogging.What is muscular endurance and why is it important for triathletes to develop muscular endurance? ![]() If your goal is to build muscular endurance, you will decrease the amount of weight you use so that you can continue to perform repetitions over the course of a workout without failure, continuing to exercise for 30 minutes or more. Depending on the amount of weight you use to perform the exercise, this might be anywhere from three to 12 repetitions. If your goal is building strength, your workouts will consist of heavy loads that fatigue you to failure within a short number of reps. This can be caused by factors such as an increase in lactic acid in your muscles, which occurs when you exert your muscle for long periods, or a lack of neural impulses sent to your muscles that occurs when they are overworked, even for a short period. Failure occurs when they can no longer contract. When your muscle can no longer perform the movements you want at maximum efficiency, they begin to fatigue. Activities such as power walking, swimming, cycling, aerobic dancing, jogging, using a cardio machine or circuit training for extended periods create endurance workouts. You don’t need to use weights to improve endurance. Prolonged use of your muscles, rather than extreme resistance, helps you improve your endurance. Strength helps you lift a heavy object with a single, powerful movement, while endurance helps you play football or tennis for several hours. Muscular endurance helps you use your muscles for longer periods of time. If you wanted to use 60 percent of your max to perform a warm-up or a circuit-training set, you’d put 120 pounds on the barbell. For example, if you can lift a barbell with 200 pounds of weight one time before failure, that is your maximum weight. Bodybuilders often create workouts using their maximum strength to create loads for sets. ![]() As your muscles repair these tears, they grow larger, giving you more strength. To build strength, create resistance against your muscle to the point that you cause small tears in the fibers. The resistance might be a weight or exercise bands, an opposing athlete or an object at your workplace that you need to lift. Muscle strength is your ability to exert your muscles against resistance.
