Intensity associated with anaerobic threshold is another important factor that determines endurance. It marks an intensity level where aerobic and anaerobic processes are in equilibrium; over this point, anaerobic processes dominate. This point is at an intensity of 20%–30% higher (VO2max) in professional athletes compared to less trained individuals. The main goal of endurance training is to increase the anaerobic threshold, because this improves training efficiency. Determining factors of VO2max react differently to different training intensity and duration, and genetic factors also determine the VO2max of an individual. Show
Muscular endurance refers to how long muscles can sustain exercise. Improving muscular endurance can help enhance overall health and fitness. This article explores the benefits of muscular endurance, the best training routines to enhance it, and how people can adapt these techniques into common exercises. We will also look at tips to prevent injury during training and how to design an exercise program that could lead to long-term performance and health benefits. What is muscular endurance?Share on PinterestGary Yeowell/Getty Images Muscular endurance is the ability to continue contracting a muscle, or group of muscles, against resistance, such as weights or body weight, over a period of time. Increasing the performance of these muscles means they can continue to contract and work against these forces. Greater muscular endurance allows a person to complete more repetitions of an exercise, for example, pushups or squats. Benefits of muscular endurance trainingAccording to the American Council on Exercise (ACE), the benefits of muscle endurance include:
How to measure muscular enduranceMuscular endurance tests measure how many repetitions of a movement people can do before the muscles reach a state of fatigue and cannot continue the exercise. Many tests focus on measuring upper and lower body muscle endurance by measuring how many pushups, squats, or situps people can achieve. A person can work with fitness instructors to measure muscular endurance or record how many repetitions of a particular exercise they can perform before reaching the fatigue state. How to improve enduranceTo increase muscular endurance, ACE recommend a combination of lower and upper body exercises, with strengthening exercises to target the whole body. Moderate resistance training, with short intervals in between for rest, creates short bursts of tension to build strength. Circuit or high-intensity interval training (HIIT) can be a suitable way to combine cardio and strength training into one workout. Unless a person’s fitness goals involve training for a particular endurance-based sport, training for muscular endurance alone may not be the most appropriate strategy. The best exercise programs mix strength and muscular endurance training. Some evidence also suggests that exercise programs that people find enjoyable may be more likely to generate long-term benefits, as they may be more likely to stick with them. A2015 studycomparing HIIT and steady-state training notes: “Variety in the type of exercise is as important as the type of exercise. Particularly considering that the health benefits of exercise have to be viewed in the context of the likelihood that exercise is continued for several years, not just the weeks of a controlled study.” Training for muscular enduranceWhen training to improve muscular endurance, what matters most is not the type of exercise, but how people design their workout. People should take into consideration the following when tailoring a workout to boost muscular endurance:
According to the National Strength and Conditioning Association, individuals training for muscular endurance should aim to complete three or more sets of 15 or more exercise reps with a load that is 50% or less of their one rep max (RM). A person’s one rep max is the maximum load with which a person can complete one repetition of an exercise. For example, a person may wish to use the leg press machine at the gym to build endurance in the legs. If they have an RM of 300 pounds (lbs), they should aim to perform 2–4 sets of 15 or more reps with a load of 150lbs or less, with brief rest periods between sets. As their muscular endurance for this exercise increases, they may wish to make the exercise more challenging by reducing rest times between sets, or increasing the reps per set, rather than increasing the load weight. A person can apply the same principle of high rep and set volume, low–moderate load, and short rest periods to any exercise, such as bench presses, dumbbell curls, pushups, or squats. People can choose exercises that suit their preferences and are challenging yet enjoyable enough to sustain training. Example exercisesAs we have already mentioned, there are no specific exercises that are better for training muscular endurance than others. The design of a training program makes it suitable for endurance training. However, ACE recommend the following exercises for building muscle endurance, which a person can perform at home without equipment: PushupShare on Pinterest A pushup works the triceps, chest, and shoulder muscles.
A person can also work the tricep muscles more by placing their hands close together and turn them inward, so the fingers and thumbs form a diamond shape. To make the exercise easier, a person can place their hands on a bench or other stable, raised surface. People can also modify a push up by placing the knees on the floor to make it easier, or lift one leg off the floor to make it more difficult. SquatShare on Pinterest A squat works the glutes, calves, quads, and core muscles.
Abdominal crunchShare on Pinterest An abdominal crunch works the abdominal muscles:
Pike crunchShare on Pinterest Another example of an abdominal crunch is the pike crunch:
A person can also hold a stability ball between their ankles during this exercise. LungeShare on Pinterest A lunge works the abs, buttocks, hips, and thighs:
PlankShare on Pinterest A plank works the core and back muscles.
A person can modify this exercise by resting on the forearms instead of the palms if they find it challenging to hold the plank position with straight arms. Preventing injuryTips to prevent injury during a workout include:
Summary Muscular endurance is a muscle’s ability to continue contracting against resistance over a period of time. What factors affect muscular endurance?It's affected by several factors including muscle fibre types (slow and fast twitch muscle fibre proportions), endurance training, strength, genetics and trainability.
Which of the following best describes about muscular endurance?Muscular endurance is the ability to continue contracting a muscle, or group of muscles, against resistance, such as weights or body weight, over a period of time. Increasing the performance of these muscles means they can continue to contract and work against these forces.
What factors affect muscular strength?Some of the most important contributors to strength include the following:. Nervous system.. Muscle fibers.. Muscle attachment points.. Body proportions.. Frame size.. Genetics.. Which is the best example of muscular endurance?Long-distance running is a sport that requires muscular endurance. During a race, a marathon runner's body performs the same movement and stride, over and over again. This requires their muscles to have an advanced level of endurance to avoid injury or extreme fatigue.
