Does Weight Training Benefit Golfers?
The authors suggest that Heavy Resistance Training (HRT) with Ballistic movement patterns negatively impacts performance on the golf course.
In the past 10+ years, many elite golfers have succumbed to the notion that increasing strength and muscle mass improves performance on the golf course. We think not!
There are a host of professional golfers on extensive weight training programs who have seen a significant decline in performance.
How is that possible? Primarily because of two factors: changes in muscle girth, i.e., increased lean body (muscle) mass, and associated neurochemical adaptations in the brain and peripheral nervous system.
The SAID (Specific Adaptation to Imposed Demand) principle is widely accepted in physical science. Simply stated, the body specifically responds to the stresses placed upon it. For example, the calluses on the hands and feet are directly related to the skin’s response to overload, and overload stimulates growth (anabolism). Weight training stimulates changes in muscle size and strength, and biochemical changes in the central and peripheral nervous systems. It is estimated that one can increase strength as much as 20% in less than six weeks.
The nervous system adapts rapidly to resistance training, especially with heavy resistance weight training and resisted ballistic movements, like jump squats and rapid end-range forceful movements.
A similar response to stresses affects the nervous system by the process of neuroplasticity. Neuroplasticity is the brain’s ability to form new neural connections throughout life. This reorganization within the brain is directly related to how the body ages and the consistency of physical and mental stimulation. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease, and rapidly adjusts their function in response to new situations, like exercise (particularly weight training), improved nutrition and absorption, and managed stress management.
Many experts believe that heavy-load resistance training, resulting in significant increases in body mass, can hinder body mechanics, including range of motion, motor control, and movement pattern changes particularly important to a coordinated golf swing. Heavy weight lifting changes motor learning, coordination, and body composition. Consider hitting a 90-yard wedge into the green with two added inches of muscle to the chest and upper back. That swing is not the same as before the added mass.
Motor control and coordination are also affected. Inappropriate exercise regimes change communication and motor sequencing patterns required to make correct ball contact, resulting in poorer performance.
Injuries compound the problem of bio-mechanics and a coordinated swing through the body’s self-protection reflex known as “protective guarding”, which alters movement patterns in an effort to reduce overloading the injured area.
So, put on muscle mass, have a few surgeries and it’s no wonder that the golf swing changes. Rather than aggressive strengthening for these injured golfers, we’d suggest a more nuanced fitness program that focuses on balanced and consistent nutrition, maintaining lean body mass, improving the quality of sleep (rest & recovery), and refraining from heavy weight resistance exercise and explosive/ballistic movements.
Summary
The results of heavy resistance, ballistic movement exercise training methods create increased muscle mass and alterations in motor control, coordination and timing, which negatively influences precise smooth movement patterns required to insure consistent ball striking.
