Pursuing your dog, regaining your balance before a fall, or leaping over a large puddle\u2014these scenarios share a common thread: they all demand power, or the capacity to generate force rapidly. This crucial aspect of fitness is often neglected, yet experts argue it warrants greater focus.<\/p>\n
As we age, maintaining mobility, cardiovascular health, and strength becomes essential for overall well-being. Recently, strength training has gained popularity due to its proven benefits in building muscle mass, which helps maintain strength, protects bone integrity, and enhances mobility over time. However, when engaging in actions like lifting oneself from a chair or quickly moving to prevent a fall, muscle size alone is not sufficient; power is also required.<\/p>\n
Oly Perkin, a researcher at the University of Bath who specializes in health-related exercise, illustrates this concept using the example of shot put. “You may possess the strength to lift the shot put from the ground to your shoulder, which is primarily reliant on muscle mass. However, to quickly launch the shot into the air, a different type of strength is necessary,” he explains.<\/p>\n
The ability to generate this explosive force hinges on the speed and effectiveness of the brain-muscle connection, which is governed by the nervous system. For younger individuals who are physically active, enhancing power can be a protective measure against injuries and can also aid those engaged in weightlifting to overcome training plateaus. However, the significance of power training may be most pronounced in mitigating some age-related declines.<\/p>\n
Perkin notes, “Muscle atrophy is an inevitable part of aging, regardless of activity levels. By ensuring that both muscle and neural functions remain robust, individuals can better preserve their physical capabilities throughout their lives. Even if muscle mass diminishes, there is substantial evidence indicating that one can still optimize the use of existing muscle.” <\/p>\n
Unfortunately, power tends to diminish more rapidly than strength. Typically, individuals lose approximately 1-2% of muscle mass annually after turning 40, but muscle power can decline earlier and at a much faster rate. The good news is that power can be developed through specific training.<\/p>\n
Muscle growth is achieved by lifting heavy weights several times a week, progressively increasing the load as it becomes manageable. This method creates tension in the muscle fibers, triggering a remodeling process that strengthens them for future workouts. In contrast, power training focuses on moving lighter weights or one’s own body weight as quickly as possible. This can involve plyometric exercises, such as box jumps, or weighted movements like medicine ball throws, snatches, and kettlebell swings, with the weight being around a moderate difficulty level.<\/p>\n
For older adults or those with limited mobility, power training can begin with simpler exercises. For example, wall push-offs involve leaning against a wall with bent arms and pushing away with speed. <\/p>\n
Perkin emphasizes that while power training is beneficial for everyone, it is particularly advantageous for older individuals who may have experienced significant muscle loss. When muscle deterioration leads to immobility, rebuilding muscle becomes challenging. However, enhancing the nervous system’s capacity to activate the remaining muscle is still feasible. “Building muscle in later years is difficult due to physiological constraints,” he states. “Yet, most older adults still possess a good potential for improvement in neural function. Notable progress can often be observed within three to four weeks.” <\/p>\n
If you’re considering incorporating power training into your routine, Perkin, along with colleagues Alex Dinsdale from Leeds Beckett University and Leigh Breen from the University of Leicester, offer some advice. A practical method to assess your need for power training is to determine if you can perform a squat but struggle to jump off the ground more than a few inches. For those who have already developed some power, jumping exercises can serve as effective progress indicators. Dinsdale mentions that when working with athletes, they frequently measure power through jump tests, including static jumps onto boxes or broad jumps from a standing start.<\/p>\n
For older or less active individuals, the sit-to-stand test is a useful evaluation tool. Sit in a chair without armrests, cross your arms over your chest, and keep your feet flat on the floor. Count how many times you can rise from sitting to standing within 30 seconds; older adults should aim for at least 11 repetitions.<\/p>\n
Perkin advises using the same sit-to-stand exercise to enhance power by performing three sets of 12 to 15 repetitions while wearing a weighted vest.<\/p>\n
“While the primary objective should be overall health and longevity,” Breen notes, “everyone has specific goals they wish to achieve.” Keeping these goals in mind can serve as motivation, especially considering that visible results may take longer to manifest compared to strength training. Goals need not be extreme, such as training for a marathon; they could simply involve regaining functional abilities lost over time, like being able to dispose of trash or play with grandchildren. “It’s crucial to remember the purpose behind our training efforts,” Breen adds.<\/p>\n
All experts agree that power training should follow a proper warm-up but should be performed early in the workout. Developing neuromuscular speed is more challenging when muscles are fatigued, making timing critical for effective power training.<\/p>\n","protected":false},"excerpt":{"rendered":"
