There are some, notably on-line, who continue to spread incorrect and deceptive information about weighted ball coaching. Our dialogue here will deal with Overload/Underload (OU) training in normal, and its application to baseball and softball in certain.

OU Teaching Defined
Utilizing excess weight-modified implements that are in any other case identical
to those utilized in the course of competitiveness
The weights of these modified applications weigh both far more and significantly less than the normal aggressive weight.
Such instruments let athletes to educate more precisely for their activity. Activity-specific energy and ability are formulated by actions with resistance or support that imitate the joint motion of the ability – Unique RESISTANCE Teaching. What can make this type of schooling so powerful is that the weights of the modified tools applied are weighty adequate to generate a conditioning influence, still light more than enough to not adversely influence the athlete’s mechanical competencies.
Usually, OU Education is employed to boost an athlete’s Ability. Electric power is described as the fee at which one can perform work, or the capability to exert muscle mass power promptly. This ability is similar to, but unique from energy, which is defined as the means to exert muscle drive.
As an instance, energy is shown as the means to decide on up a 30 oz. bat. Power is demonstrated by the ability to travel a baseball 400+ toes when swinging that 30 oz. bat.
As lengthy as the applications employed are not way too hefty, mechanics are not impacted, generating OU Schooling what I phone “skill-neutral.” In accordance to posted knowledge (see underneath) the ideal fat array for conditioning and performance improvement is up to 20% +/- the bodyweight of the competitive employ. I do NOT advocate making use of baseballs weighing extra than 6 oz., or softballs heavier than 8 oz. There is some details that indicates working with a lot heavier balls can negatively influence throwing mechanics, quite possibly leading to arm challenges. Extra motor-units are recruited while throwing these weighty balls that are then not applied when the frequent competitive ball is utilised. As relates to our dialogue below, the modified implements ball players can use are weighted baseballs and softballs, and a variety of weights of baseball/softball bats, and/or gadgets attached to these bats.
Conversely, this style of coaching would not be handy for training other athletic talent spots, for illustration, shooting or throwing precision. OU teaching could support a golfer drive their tee pictures further, but it wouldn’t aid reduce their slice if they have one particular, or or else help them to strike straighter drives. OU training could aid a younger basketball participant who is possessing issues hoisting a basketball higher ample to make a shot in a 10 foot hoop, but the shot even now has to be accurate ample to go in. Precision coaching needed for a specific ability would for that reason be carried out apart from electrical power perform.
If I was operating with a pitcher who experienced management complications, I would not split out the weighted baseballs and count on teaching of this type to assist him toss strikes. I would search at his mechanics and make any needed changes, and possibly suggest some drill operate to enable fortify the new principles currently being taught. Such a participant could also be doing the job with weighted baseballs/softballs as element of their all round teaching regimen, but this would come about at a diverse time, and for the applications of developing additional electricity and pace driving his/her throws as perfectly as conditioning the throwing structures of the arm.
A likely side-benefit of OU schooling is that a player could make improvements to their accuracy by advantage of the increased amount of reps or throws they are accomplishing. This would be an artifact of the most important objective of improving upon electric power, on the other hand, and not the principal objective of OU schooling.
A Brief Background OF OU Exploration AND Training
The very first study involving OU coaching was executed in the 1970s by the Soviet Union and East-European keep track of and area groups. A good offer of this research has been published in prestigious, peer-reviewed journals close to the earth. Shot-putters, javelin, discus and hammer throwers, and sprinters have been the early adopters of this education system.
Research with baseball players dates back to the 1960s. This is just a sampling of scientific tests involving OU Training and baseball. There are dozens a lot more relating to OU Teaching typically:

OTHER Athletics THAT USE OU Schooling
About and underloaded implements and approaches are used really proficiently by athletes in numerous athletics to augment performance:
Observe & Industry: heavier and lighter discuses, javelins, shot balls (shot putters) and hammers sprinting with resistance, such as pulling weighted sleds, carrying weighted vests, and downhill operating on a slight downward slope, currently being towed although working, and functioning on a higher speed treadmill (overSPEED education) .
Swimming: sporting swimming gloves that let for far more drinking water to be pulled in the course of an arm stroke swimming even though dragging an carry out or in any other case artificially creating drag on a swimmer.
Heavier footballs (over the standard 15 oz) are thrown by quarterbacks heavier basketballs are utilised by basketball gamers. Boxers train with unique weights of boxing gloves.
Be aware that ALL of these coaching implements are utilised to enhance Electric power and/or Pace via the joint variety-of-movement (ROM) in the exercise being trained, which can guide to improved performance.
THE Rewards OF OU Education
Suitable strength and conditioning regimens, this kind of as OU Schooling, can lessen and even avoid arm accidents linked to throwing by growing Power/Endurance. Greater Strength – will help avert damage. Improved Stamina – can help sustain throwing velocity, lets for a lot more pitches to be thrown just before tiring.
The muscle mass, tendons, ligaments and bones (even nerves) of the shoulder and arm in common will positively adapt to an acceptable improve in training load. They grow to be harder and extra tough, ready to manage increased workloads. This kind of teaching should conform to the subsequent two tips:
1) The schooling load is enough to make the ideal education result, nevertheless not so good as to negatively affect throwing (or hitting) mechanics.
2) The thrower’s application introduces OU training slowly and systematically, utilizing a coaching principle identified as Progressive Overload (Clarkson & Watson, 1990). This principle states that “energy and stamina are not able to be amplified except if the muscle tissues are pressured further than their ordinary workload. To boost the workload, increase the frequency, period and intensity of your work out method.”
To proficiently and safely maximize throwing velocity, intensity is greater by applying 20% +/- OU balls, length is improved by slowly growing the number of OU throws performed with each individual workout, and frequency is amplified by the range of days of throwing workout routines. Arm/shoulder structures educated in this manner are a lot more capable of dealing with the typical aggressive recreation requirements, which are significantly less than those people imposed by the OU conditioning. An arm conditioned for building a lot of throws with a 6 oz ball will far more than probably out-conduct an arm trained only to perform underneath a 5 oz. load (ability, mechanics and around-use things to consider apart).
Dr. Mike Marshall, in his Pitching Ebook (Chapter 32, pp. 5 & 6), describes a idea he calls “Plioanglos Coaching” as a implies of schooling the exterior rotator cuff muscle tissues (decelerators). This is equivalent to the ideas expressed higher than:
“Plioanglos training signifies incorporating resistance to ahead ballistically rushing pitching arms to boost capacities of lengthening deceleration muscle tissue to prevent.”
Probably this is most effective summed up by way of the properly-known conditioning theory S.A.I.D. – Precise Adaptation to Imposed Calls for (Wallis and Logan, 1964). This basic principle states that the body will adapt to pressure imposed on it (as lengthy as it is not too much, in which circumstance the overall body breaks down). A single safe and successful way of doing this is with OU Instruction, employing the aforementioned recommendations.
Enhanced on-field overall performance – improved throwing velocity (or bat speed).
Increased arm speed through the throwing Array of Motion (ROM). This attribute is produced by throwing a ball weighing 20% considerably less than the competitive ball. Simply because the ball weighs significantly less, the arm moves far more rapidly via its ROM, main to increased throwing velocity. Throwing lighter balls has been shown (equally clinically and on the ball subject) to be one particular of the best suggests of rising throwing velocity. Swinging appropriately lighter bats assists produce greater bat pace. This is also recognized as overSPEED teaching.
A take note on “gentle” ball instruction, significant school and older gamers: This can be an fantastic way for pitchers in distinct to get a superior volume of throwing in in between starts off with less anxiety on the arm. For youth ball players – why do we make lighter bats for more youthful ball players, nevertheless make them throw the identical 5 oz ball that fellas like Roger Clemens and Randy Johnson toss? That youth fields are more compact can make minimal difference when it will come to the size of some of the throws that young players have to make. These minor arms however have to create a wonderful deal of drive to propel the ball. Underweight balls (4 oz.) are a Terrific software for gamers of all ages.
Increased neuromuscular conditioning.
According to Vern Gambetta, Energy and Conditioning Mentor for the Chicago White Sox, the principal supply of fatigue in baseball pitching is not metabolic, but neural. The metabolic calls for – conditioning – are just not that excellent in baseball or softball. Really don’t misunderstand – I am speaking in this article of the expertise expected to be a very good hitter or pitcher. Getting perfectly conditioned is nevertheless important, as this will support protect against injury, but no doubt you have witnessed players like John Kruk, David Wells, Tony Gwynn, and others. Large level performers who are not significantly properly conditioned.
Neural exhaustion occurs at the motor-unit stage. In the act of pitching, for instance, the Central Anxious Process sends a nerve impulse to a motor unit (MU) in the shoulder concerned in this approach. The capability of these MUs to transmit these signals, with optimum frequency and pace, diminishes about time. This “breakdown” occurs at the nerve synapse/biochemical amount, which THEN sales opportunities to slower and weaker muscle contractions.
In baseball pitching, throwing muscle tissue and tendons in the shoulder are stretching and contracting regularly whilst accelerating and decelerating the arm throughout an overhand throw – constant biochemical action at the neuromuscular junction. As neural tiredness sets in, it becomes manifest in mechanical problems. For illustration, a pitcher dropping their shoulder later in the activity, leading to a reduction of management or velocity. The challenging detail is, this “tiredness” is generally not felt by the pitcher, but it happens nevertheless.
This is where by good conditioning (OU Schooling) comes in. Study has revealed that neurons adapt to strain substantially like muscles do. Motor neurons uncovered to large-frequency impulses close up with more made neuromuscular junctions which seem a lot more capable of dealing with higher-intensity impulses better than individuals not exposed to very similar pressure. The S.A.I.D. basic principle in influence all over again.
Does this imply OU Training is fool proof, and has in no way harmed a participant? Of course not. Most any type of conditioning, performed incorrectly, can result in problems or harm. Throwing alone, be it footballs, baseballs, rocks or regardless of what, has harmed numerous a throwing arm. Managing is the trigger of several knee and ankle accidents. Shoulder difficulties among swimmers are frequent. Ice skaters typically undergo from some incredibly agonizing leg ailments. I could go on, but you get the stage. All of these injuries and troubles come about as a element of the athlete’s regular observe and aggressive routines. Executing them properly minimizes the risk, of study course. So does a selection of power and conditioning procedures, together with OU Teaching.
