Power fades faster than strength as we age—and most of us do not realize it until we step onto a basketball court or try to sprint for the first time in years. This sudden realization often catches active adults off guard, revealing a hidden decline in physical performance that standard weightlifting routines fail to address.
Recently, strength coach Jud Linehart addressed listener questions regarding speed, power, and athleticism for individuals navigating their 40s. His insights broke down the underlying science of why the human body slows down over time, alongside the specific training methodologies that actually work to reverse the trend. His expert advice goes well beyond the simplistic notion of just lifting lighter weights faster. Instead, Linehart focuses heavily on three critical physiological systems that most everyday gym-goers completely ignore: the rate of force development, compensatory acceleration, and proper movement sequencing.
Why Lifting Weights Isn’t Enough for Speed
The discussion was prompted in part by a 43-year-old listener named Mark, who wrote in after feeling unexpectedly slow during a recreational pickup basketball game, despite having lifted weights consistently for years. Linehart explained to his audience that fundamental strength and physical power are fundamentally distinct physiological qualities.
Strength is ultimately just the production of force, whereas power is force divided by time—essentially measuring how much mechanical work a person can perform in a given window. Scientific literature strongly confirms this distinction. Research demonstrates that power—the speed at which you can generate force—declines much more rapidly with age than maximal strength. A landmark 2010 review published in Sports Medicine found that muscle power diminishes by approximately 3.5 percent per year after age 65, which is nearly double the annual rate of strength loss.
Most conventional gym workouts focus on slow, controlled repetitions featuring a distinct eccentric, or lowering, phase followed by a concentric, or lifting, phase. While this approach is fantastic for building muscle mass and establishing a foundational base of strength, it entirely fails to train the nervous system to produce force rapidly. In fast-paced athletic environments like basketball, an athlete typically has less than two-tenths of a second to develop force the moment their foot strikes the ground. If an individual’s training regimen does not match that strict speed requirement, the force they generate ultimately arrives too late to be of any functional use.
The Three Systems That Determine Athletic Performance
Linehart breaks down the complex mechanics of power development into three distinct yet closely overlapping components. The first of these is the rate of force development, which dictates how quickly muscles can produce force immediately after the brain transmits a signal. This metric represents the vital difference between reacting fast enough to catch oneself during an unexpected stumble versus landing awkwardly and suffering a severe injury. To actively improve this system, Linehart recommends incorporating dead-stop training—exercises where movements begin from a complete standstill, entirely devoid of the stretch reflex that normally assists the lift. Examples include pin squats, floor presses originating directly from the ground, and deadlifts performed without bouncing the plates between repetitions. Fast eccentric movements featuring a quick turnaround at the bottom can also help, provided an individual’s joints can safely tolerate the stress.
The second component is compensatory acceleration, which describes an athlete’s ongoing ability to continue accelerating an object as its speed increases, much like shifting gears in a manual automobile. As Linehart noted, a person can be exceptionally strong in first gear when moving slowly, but the critical question is whether they can successfully shift gears to match rising speeds. In traditional lifting movements, once a barbell starts moving smoothly, momentum frequently takes over, causing the lifter to stop applying maximum force halfway through the repetition. To counteract this, coaches utilize variable resistance, attaching chains or heavy bands to a barbell so that the weight progressively increases as it is lifted, forcing the athlete to accelerate through the entire range of motion. Ballistic training—such as throwing medicine balls, executing maximal vertical jumps with a barbell and safely letting it drop, or pushing a light sled at maximum velocity—serves a similar purpose by teaching the body to maintain acceleration all the way through a movement.
The third and final component involves movement patterns and proper sequencing. Even if an athlete’s muscles possess the capacity to produce force rapidly, that generated force must flow seamlessly through the entire kinetic chain in the correct temporal sequence. If the brain has not practiced specific movement patterns—such as planting a foot at the precise biomechanical angle, rotating the hips prior to the shoulders, and flexing or extending joints in the correct order—the power an individual has built in the gym will simply fail to transfer onto the court or field. This necessitates breaking down the exact movements required for a given activity and practicing them with dedicated volume, whether that involves a hard plant step, a sharp athletic cut, or a powerful drive to the hoop.
What About Intent?
One of Linehart’s most central takeaways is that how an individual lifts matters just as much as what they lift. He emphasizes that mental intent has just as much to do with the ultimate training adaptation as the external load, the number of repetitions performed, or the specific exercise selected. Simply trying to move a weight as explosively and rapidly as possible during the concentric phase of a lift in the weight room significantly improves both the rate of force production and compensatory acceleration.
Two individuals can perform the exact same exercise using identical weights, but if one person grinds through slow, fatiguing repetitions while the other explodes upward with maximum velocity, they are training entirely different physiological qualities. Velocity-based training, which involves moving submaximal loads as fast as humanly possible, has been consistently demonstrated in multiple studies to improve power output and the rate of force development far more effectively than traditional slow-tempo resistance training.
Should You Sprint in Your 40s?
When another listener named Brian asked whether sprinting was an activity he should attempt to reintroduce into his fitness routine after a 20-year hiatus—or if he would simply be inviting a pulled hamstring—Linehart offered a measured response. He advised that while sprinting should not be attempted immediately the following day, it remains an invaluable pursuit for long-term health.
Sprinting generates immense ground reaction forces reaching up to eight times an individual’s body weight with every single stride, meaning the physical frame must be systematically conditioned to tolerate that extraordinary stress. However, nothing quite compares to sprinting when it comes to staying biologically young at a cellular level, enhancing telomere length, and training peak power production. Building toward sprinting requires a careful, methodical progression spanning several months rather than weeks, alongside careful attention to bodily feedback. If an individual feels even a minor tug or unusual tightness during a session, Linehart stresses that the workout must be halted immediately to avoid the muscle strains that commonly plague those who ignore early warning signals.
Can You Build Muscle and Speed at the Same Time?
Addressing how to balance muscle hypertrophy with increases in speed and explosiveness while maintaining a four-day training week, Linehart delivered a blunt assessment. He noted that attempting to accomplish both goals simultaneously is exceptionally difficult because increasing muscle tissue past a certain threshold eventually increases the body’s moment of inertia, which can naturally slow limb speed and hamper acceleration.
While individuals can successfully maintain or build baseline strength while simultaneously improving speed and power, they must deliberately pivot their focus away from pure hypertrophy training. To manage this effectively, athletes can utilize periodization strategies that break the training year into distinct phases, always prioritizing fast movements before slow movements within any single workout. By placing speed and power work first, followed by strength and hypertrophy training last, the nervous system remains fresh and capable of making the precise adaptations required for true athletic explosiveness.
