Ballistic training, also known as compensatory acceleration training, [1] [2] uses exercises which accelerate a force through the entire range of motion. [1] [3] It is a form of power training which can involve throwing weights, jumping with weights, or swinging weights in order to increase explosive power. [4] The intention in ballistic exercises is to maximise the acceleration phase of an object's movement and minimise the deceleration phase. For instance, throwing a medicine ball maximises the acceleration of the ball. [5] This can be contrasted with a standard weight training exercise where there would be a pronounced deceleration phase at the end of the repetition i.e. at the end of a bench press exercise the barbell is decelerated and brought to a halt. Similarly, an athlete jumping whilst holding a trap bar maximises the acceleration of the weight through the process of holding it whilst they jump- where as they would decelerate it at the end of a standard trap bar deadlift. [6]
The word ballistic comes from the Greek word βάλλειν (ballein), which means “to throw”. Evidence of ballistic training can be seen throughout recorded history, especially in depictions which show the throwing of a large stone (stone put). Other ballistic disciplines from antiquity include the javelin throw and the discus throw. The hammer throw is a younger discipline, known from the 16th century. [7]
Such throws have been both a popular sporting pastime, and a training method employed by soldiers. Ballistic training was first used in the modern day by elite athletes when they were looking to enhance their ability to perform explosively. Commonly used modern ballistic training exercises are medicine ball throws, bench throws, jump squats, and kettlebell swings. [4]
Ballistic training requires the muscles to adapt to contracting very quickly and forcefully. This training requires the central nervous system and muscular system to coordinate and produce the greatest amount of force in the shortest time possible i.e. to increase the rate of force development (RFD). [9]
Ballistic training exercises involve dramatically increasing the acceleration phase of the weight's movement and reducing the deceleration phase. For example, in a medicine ball throw the weight is accelerated throughout the exercise in order to propel it into the air. In a weighted jump, the weight continues to be held and so continues to be accelerated throughout the concentric phase of the jumping action. This can be contrasted with standard weight training exercises where the weight is decelerated and brought to a halt at the end of the repetition. For example, in a bench press the barbell is decelerated to a halt at the end of a standard repetition, but in a bench press throw it continues to be accelerated as it is thrown into the air. An exercise performed in a ballistic manner allows for the weight to be moved more forcefully. [10]
1. Muscle recruitment principles. Ballistic lifts force the muscles to produce the greatest amount of force in the shortest amount of time. In accordance with Henneman's size principle muscle fibers are recruited from a low to a high threshold as force requirements increase.
2. Speed of the movement. To ensure full muscle fiber recruitment the speed of the lift must be propulsive through the entire range of the movement up until release.
3. Intensity of the exercise. The duration of the lift should be measured by repetitions or time. The lift should be stopped when the bar decelerates. Research has shown the 6-8 repetitions or 20–30 seconds produces the best results.
4. Cardiovascular benefits. Ballistic exercises performed continuously for a minimum of 20 seconds followed by a 30-second rest period and then repeated until deceleration occurs has been proven to elevate the heart rate to training zone level. [11]
5. Co-ordination. Research at the University of Connecticut found that high-intensity training has profound effects on the nervous system. The exercise had to be of an intensity that elevate the heart rate to 90% of maximum rate and had to sustain that rate for at least 20 seconds.
6. Electronic measurement. There are several electronic measurement systems that measure the velocity, power, and effectiveness of a lift. The athlete should stop the lift when the speed of a lift has fallen to 90% of their previous lift. The 90% number signals that there has been a significant change in the recruitment of the fast-twitch muscle fibers. Below the 90% number the lift is no longer ballistic
7. Specificity of training. Ballistic training emphasizes throwing and jumping with a weighted object. Research has resulted in positive increases in vertical jump, throwing velocity, and running speed. There is limited transfer to a specific sport.
Ballistic exercises have traditionally been left out of metabolic conditioning workouts and training programs. This may be due to the fact that they are often technical lifts, or lifts/exercises for which technique is crucial to safe and effective completion. However, with the extensive availability of information and guidance in learning and developing proficiency in ballistic exercise, this trend is changing.[ citation needed ]
Many training programs which employ circuit training or metabolic conditioning now include ballistic exercises such as kettlebell cleans and snatches, Olympic lifts and variations, throws and plyometric variations. The benefits of their inclusion in these types of programs include higher levels of motor unit recruitment, higher caloric burn and improvements in a number of measurable athletic outputs.[ citation needed ]
Strength training, also known as weight training or resistance training, involves the performance of physical exercises that are designed to improve strength and endurance. It is often associated with the lifting of weights. It can also incorporate a variety of training techniques such as bodyweight exercises, isometrics, and plyometrics.
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help the hip muscles.
The deadlift is a weight training and strength training exercise in which a loaded barbell or bar is lifted off the ground to the level of the hips, torso perpendicular to the floor, before being placed back on the ground. It is one of the three powerlifting exercises, along with the squat and bench press, as well as a frequent lift in strongman. It is also occasionally used in armlifting.
An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied. This is in contrast to isotonic contractions, in which the contraction strength does not change, though the muscle length and joint angle do.
Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping. Plyometrics are primarily used by athletes, especially martial artists, sprinters and high jumpers, to improve performance, and are used in the fitness field to a much lesser degree.
The snatch is the first of two lifts contested in the sport of weightlifting followed by the clean and jerk. The objective of the snatch is to lift the barbell from the ground to overhead in one continuous motion. There are four main styles of snatch used: snatch, split snatch, power snatch, and muscle snatch. The full lift is the most common style used in competition, while power snatches and muscle snatches are mostly used for training purposes, and split snatches are rarely used. Any of these lifts can be performed from the floor, from the hang position, or from blocks. In competition, only lifts from the floor are allowed.
In weight training, a kettlebell is a cast-iron or cast-steel ball with a handle attached to the top. It is used to perform many types of exercises, including ballistic exercises that combine cardiovascular, strength and flexibility training. Kettlebells are the primary equipment used in the weight-lifting sport of kettlebell lifting.
One-repetition maximum in weight training is the maximum amount of weight that a person can possibly lift for one repetition. It may also be considered as the maximum amount of force that can be generated in one maximal contraction.
Exercise equipment is any apparatus or device used during physical activity to enhance the strength or conditioning effects of that exercise by providing either fixed or adjustable amounts of resistance, or to otherwise enhance the experience or outcome of an exercise routine.
Complex training, also known as contrast training or post-activation potentiation training, involves the integration of strength training and plyometrics in a training system designed to improve explosive power. According to Jace Derwin:
Strength training and plyometric training are both effective measures for increasing athletic performance independent of each other, but a true program designed for power-based athletes needs to incorporate both disciplines. A study done in 2000 in the NSCA's Journal of Strength and Conditioning Research measured three different training protocols: strength training, plyometric training, and a combination of both. The group that used combined methods was the only group that showed significant increases in BOTH strength and power.
A vertical jump or vertical leap is the act of jumping upwards into the air. It can be an exercise for building both endurance and strength, and is also a standard test for measuring athletic performance. It may also be referred to as a Sargent jump, named for Dudley Allen Sargent.
The following outline is provided as an overview of and topical guide to exercise:
The overhead press, also known as the shoulder press, strict press or military press, is an upper-body weight training exercise in which the trainee presses a weight overhead while seated or standing. It is mainly used to develop the anterior deltoid muscles of the shoulder. The standing version was once a component of the sport of Olympic weightlifting as part of the clean and press movement, but was removed in 1972 due to difficulties in judging proper technique.
The Bulgarian bag, also known as the Bulgarian training bag, is a crescent-shaped piece of exercise equipment used in strength training, plyometric weight training, cardiovascular training, and general physical fitness. The bags are made of leather or canvas and filled with sand; they weigh from 11 pounds (5.0 kg) to 50 pounds (23 kg) and have flexible handles to allow for both upper and lower body training, and for building grip strength.
Football strength is a training regime, considered the most complex physical quality to be developed by an athlete. The training regime, exercises used, how the exercises are performed, and the types of equipment all play important roles in achieving desired results.
Power training typically involves exercises which apply the maximum amount of force as fast as possible; on the basis that strength + speed = power. Jumping with weights or throwing weights are two examples of power training exercises. Regular weight training exercises such as the clean and jerk and power clean may also be considered as being power training exercises due to the explosive speed required to complete the lifts. Power training may also involve contrasting exercises such as heavy lifts and plyometrics, known as complex training, in an attempt to combine the maximal lifting exertions with dynamic movements. This combination of a high strength exercise with a high speed exercise may lead to an increased ability to apply power. Power training frequently specifically utilises two physiological processes which increase in conjunction with one another during exercise. These are deep breathing, which results in increased intra-abdominal pressure; and post-activation potentation, which is the enhanced activation of the nervous system and increased muscle fibre recruitment. Power training programmes may be shaped to increase the trainee's ability to apply power in general, to meet sports specific criteria, or both.
Physical training has been present in human societies throughout history. Usually, it was performed for the purposes of preparing for physical competition or display, improving physical, emotional and mental health, and looking attractive. It took a variety of different forms but quick dynamic exercises were favoured over slow or more static ones. For example, running, jumping, wrestling, gymnastics and throwing heavy stones are mentioned frequently in historical sources and emphasised as being highly effective training methods. Notably, they are also forms of exercise which are readily achievable for most people to some extent or another.
Velocity based training (VBT) is a modern approach to strength training and power training which utilises velocity tracking technology to provide rich objective data as a means to motivate and support real-time adjustments in an athlete's training plan. Typical strength and power programming and periodisation plans rely on the manipulation of reps, sets and loads as a means to calibrate training stressors in the pursuit of specific adaptations. Since the late 1990s, innovations in bar speed monitoring technology has brought velocity based training closer to the mainstream as the range of hardware and software solutions for measuring exercise velocities have become easier to use and more affordable. Velocity based training has a wide range of use cases and applications in strength and conditioning. These include barbell sports such as powerlifting and Olympic weightlifting and Crossfit, as well as rock climbing.Velocity based training is widely adopted across professional sporting clubs, with the data supporting many periodisation decisions for coaches in the weight room and on the field.
A plyometric box, also simply known as a plyo box or jump box, is a piece of training equipment used for plyometric exercises. Plyometric exercises are a type of explosive power training that uses muscle elasticity to produce rapid, forceful movements. The plyometric box provides a stable platform for performing plyometric exercises such as box jumps, box squats, and box step-ups.
Unilateral training involves the performance of physical exercises using one limb instead of two. Such exercises should be considered as being distinct from bilateral, two limbed, exercises. For example, unilateral squats use one leg, and bilateral squats use two legs. A unilateral bench press uses one arm and a bilateral bench press two arms. Depending on the exercise, this may also entail using different equipment i.e. a dumbbell instead of a barbell. Unilateral exercise is commonly involved in comprehensive training regimes and especially those of professional sports people and athletes. Usually it is used in addition to bilateral training as opposed to instead of it. Unilateral training can yield numerous benefits including improving a person's muscle balance between the left and right sides of their body, improving their sense of balance, and helping to avoid or rehabilitate injury.
