The Phases of a Plyometric Action/SSC A SSC has three phases (see fig. There is a right and wrong way to land a jumping exercise, and I see examples of the improper landing in the gym all the time. Allow at least one minute of rest between each exercise repetition to allow the neuromuscular system to recover. plyometric training of the upper ex- tremity on various performance pa- rameters (26,61,63). Lower-body plyometric exercises help the muscle groups that are responsible for running, jumping, kicking and dexterity. reduce the impact to be endured, but to increase the intensity of one-legged Some authors suggest that moderate jumps (low intensity) can be included in the A plyometric activity is divided into three phases: I) eccentric pre- load, 2) the amortization phase, and 3) concentric contraction (21,61 This is done by continuing your movement to absorb the impact of the landing. ground contact time must be as short as possible. Avoid cement floors because there is no cushioning. Plyometric exercises involve all three types of muscle contractions : eccentric, isometric and concentric. run + 2 hops and a jump into a sandpit, 2 strides run in + bounds, Depth jumping (high-very high-intensity) - jumps down and This exercise involves the athlete dropping (not jumping) to Plyometrics is based on the understanding that a concentric muscular contraction is much stronger if it immediately follows an eccentric contraction of the same muscle. During this we have energy being stored, muscle spindles stimulated, and a signal is sent to the spinal cord. this distinct method of training for power or explosiveness has been termed engaging in plyometric training. The eccentric phase is the mental preparation phase with its duration depending both the vertical and horizontal aspects of the running action. general mobility, especially about the joints When a concentric The exercise will be more So what's the correct way to land? The following are examples of the lower body and upper body plyometric For which two phases of the OPT model may plyometric exercise not be necessary due to specific adaptation goals? MAKARUK, H. et al. structural or postural problems that are likely to predispose the athlete to designed for developing elastic strength (low hurdle jumps; low drop If contact mats are not available to measure the contact time, then observe the athlete's feet. player, practising for the line out or a volleyball player interested in Prior to beginning a plyometric exercise routine, seek the advice of a knowledgeable healthcare professional. To realise the It's so brief that it's almost imperceptible to the eye. Plyometric (plyo) exercise is great for training power, and speed, and increasing strength as a result. AMORTIZATION PHASE, aka: transition phase 3. Work with a certified trainer to safely introduce plyometrics into your exercise … drop-down gives the pre-stretch to the leg muscles (eccentric phase) and the vigorous drive the arms and legs are detailed on the Leg Plyometric page and the Arm Plyometric page. jumps). This whole process is frequently called the stretch-shortening cycle and is the underlying mechanism of plyometric training. The challenge to you as a coach invoked. Phase 2 is the amortization phase, and this is when there is a pause between the eccentric and concentric phases. To visualize this phase imagine letting go of that rubberband you stretched out earlier. This creates and temporarily stores potential energy in the muscles that are about to be used for the jump. This time needs to be as short as possible otherwise the energy stored during the eccentric phase dissipates, reducing the plyometric effect, Concentric phase, or take-off phase, uses the stored energy to increase the force of the movement, Minimise ground contact time - imagine the ground is a hot surface, Minimise the flexion at the knee and hip on landing, Maximise the height you jump - jump as high as possible, Standing based jumps performed on the spot (low the spot. resilient surfaces. A cool-down should follow each session. squat twice their body weight before attempting depth jumps. Plyo exercises are intended to be performed quickly, so immediately after the jump I'd go back into the eccentric phase of my next rep and continue. right exercise. Phases of a Plyometric Exercise Plyometric exercises have three phases that focus on speed of forceful movements: The landing phase is an eccentric contraction of muscles. You can just *feel* all the stored energy about to explode when you let go... Next comes the amortization phase which occurs right at the bottom of the loading phase and right before the jump. To express this greater force, the muscle must contract within This phase is explosive, and the more you train with plyometrics the more explosive it will become. Allow three days between plyometrics sessions when planning. children. Here, elastic energy is generated and stored. bounding. plyometric training. 2); a rapid eccentric lengthening phase, the amortisation phase, and finally an explosive concentric phase (Van Ingen Schenau et al., 1997). again, to get the best training effect to keep the time in contact with the ground Plyometric exercises are a training method that are dynamic and explosive in nature. contacts. Once Plyometric exercise and weight training can be combined in complex training sessions to develop explosive power. Kinematics of the upper extremity were collected during completion of eight to ten repetitions of 90 /90 plyometric throwing exercise with three different mass medicine balls. clap in between is a particularly vigorous way to condition the arms and chest. in the region of 30 to 110 cm (Bompa et al. All athletes should undergo general orthopaedic screening before Speed and strength are integral components of fitness found in A partner steps, Multiple jumps with a run in (High-intensity) - 11 stride before plyometric training. varying degrees in virtually all athletic movements. In essence, athletes new to plyometric work should start - hop and hold, bound/hop/bound/hop over 30 metres (athletes stop and hold on Schmidtbleicher (1992) says that a ground contact time of <0.25 seconds indicates a fast stretch-shortening cycle (SSC) and to adjust the drop height to achieve this contact time. The The choice of exercises within a session and their order google_ad_height = 90; Because of the relatively immature bone structure in preadolescent intensity) - tuck jumps, split jumps, Jumps from standing (low-medium intensity) - standing The two critical factors in drop jumping are a minimal contact time with the ground and the height achieved in the drive upwards. Rapid muscle lengthening, also known as the eccentric phase, is the first phase. The 3 Phases of Plyometric Exercises Plyometric exercises have three distinct phases, an eccentric phase, an amortization phase, and a concentric phase that releases the explosive force. All plyo exercises have three unique phases: 1. An experienced athlete conducting lower body plyometrics may conduct up to Work through each exercise in a superset fashion and complete three sets of each reactive exercise before moving onto the core exercises. The amortization phase, or transition phase, is one of three parts of a plyometric exercise. loading in this exercise is governed by the height of the drop that should be And the more muscle fiber activation we get in a single instant the higher we jump, the more we lift, the stronger our movement becomes. explosive: Press-ups & hand-clap: Press-ups with a hand It is essential to realise that this demanding exercises such as flying start single-leg hops and depth jumps should On landing the athlete should stay on the balls of the feet (mid-foot). contraction. Three phases of plyometric exercise have been identified including: the eccentric phase, the amortization phase, and the concentric phase. SCHMIDTBLEICHER, D. (1992) Training for power event. There are basically three phases of a plyometric exercise and the SSC. upwards the second concentric contraction phase. The Amortization Phase 3. The third and fourth phases are more in line with “true” plyometric training – as defined by an amortization phase of 0.2 seconds or less – since they involve minimal ground contact time and greater intensity and/or complexity. There are three phases of a plyometric exercise: First is the eccentric, which is the pre-stretch where the potential energy is stored. Particular attention should be given to This stored energy is available to the muscle potential benefits of plyometric training, the stretch-shortening cycle (SSC) must be These three phases make up a stretch-shortening cycle. sought to improve power to enhance performance. or exercise. In recent years, Four parameters, medicine ball release and contact RSI is calculated by dividing the height jumped (metres) by the contact time (seconds). This is the unloading phase in which the elastic energy stored in the loading phase and redirected in the amortization phase is RELEASED. In: Komi PV (ed) Strength and power in sport. However, it should be realised that muscles seldom and adolescent children, the high forces used during intensive depth More bounding, or hopping, can be used. ECCENTRIC PHASE, aka: loading phase2. Also, the coupling time or Absorb your landing by continuing to move even after your feet have planted. Plyometric type exercises have been used successfully by many Bounding upstairs is a useful way to work on It would include:- Landing loudly- Stopping short of a full range of motion- A generally 'jerky' appearance to the motion- High impact on the lower body joints. It is important to keep the amortization phase as short as possible so that the potential energy can be converted to kinetic energy. The three phases are the loading (eccentric) phase, the transition (amortization) phase, and the unloading (concentric) phase. RAMACHANDRAN, S. and PRADHAN, B. the athlete, who catches the ball (eccentric phase) and immediately throws it back (concentric phase). intensive plyometric exercises can be incorporated into a general circuit and weight training during the early stages The Reactive Strength Index (RSI) was devised to measure the interaction of the contact time and height jumped to monitor the development of explosive power. with moderate to medium intensity exercise with around 40 contacts per session, e.g. Medicine Ball: Another means of increasing upper Finally, the athlete engages in an explosive muscle shortening movement called the … This CONCENTRIC PHASE, aka: unloading phase training for sprinting or jumping events. Overhead slams develop tremendous anterior core power, and concentric power and strength through all of the shoulder The 3 Phases Of A Plyometric Exercise Most plyo movements are comprised of three phases. (2014) Effects of Short-term Two Weeks low-intensity Plyometrics Combined With Dynamic Stretching Training in Improving Vertical Jump Height and Agility on Trained Basketball Players. PATEL, N. N. (2014) PLYOMETRIC TRAINING: A REVIEW ARTICLE. This requires careful attention to the technique used during the drill long jump, standing hop, standing jump for height, Multiple jumps from standing (medium intensity) - bounds, It's a very brief moment of pause that can be seen at the bottom-most point of my loading phase. (2014) THE EFFECTS OF SINGLE VERSUS REPEATED PLYOMETRICS ON LANDING BIOMECHANICS AND JUMPING PERFORMANCE IN MEN. perform one type of contraction in isolation during athletic movements. body strength popular with throwers is to lie on the ground face up. injury. For exercise variables recognize how different variables affect exercise. Most experts state that a A plyometric exercise consists of three phases. This is another high-intensity exercise and should only be used after some Two-legged bounds greater than one metre, begin with exercises that are fast, explosive and Higher than normal forces are put on the musculoskeletal system during plyometric exercises, so the athlete needs to have a good ?QUIETLY and FULLY! Three distinct phases happening in rapid succession are what differentiate plyometric training exercises from other forms of training, and explain why plyometric training is so effective for developing explosive power. rapid eccentric contraction. Because plyometrics is high-impact and intense exercise, check with your doctor first if you … to a minimum. session and since it is a quality session, with the emphasis on speed /* Link Bottom Left */ (This is that continuation into the eccentric phase even once you've finished your set.) The rate of stretch rather than the magnitude of stretch is of This phase is the time between the concentric and eccentric phases. google_ad_width = 160; athletes as a method of training to enhance power. Three Phases of Plyometric Training There are distinct phases in plyometric training. plyometrics. energy boost is lost if the eccentric contraction is not followed immediately by a concentric the shortest time possible. The first is known as the eccentric phase, or landing phase and it consists of rapid muscle lengthening movement—the pre-load of the agonist muscle group. Upon the final rep, I'll still want to sink into that eccentric phase, but this time the purpose is to absorb the landing. CONCENTRIC PHASE, aka: unloading phase. then drops a medicine ball down towards the chest of It has been suggested that an athlete be able to of speed and strength is power. only during a subsequent contraction. A plyometric exercise can be broken down in three phases: Eccentric phase—rapid muscle lengthening movement Amortization phase—short resting period Concentric phase—explosive muscle shortening movement involved in the planned plyometric session. The second phase is the time between the end of the pre-stretch and the start of the concentric muscle action. Mix a few plyometric moves into your regular workout. the Leg Plyometric page. needs to be exerted when prescribing any training procedures for preadolescent to ensure there is a pre-stretch first, then the only limit is your imagination. Plyo exercises involve some kind of jump or otherwise explosive movement, which requires and improves the ability to recruit as many muscle fibers as possible in as little time as possible. Phase increases muscle spindle … over a series of obstacles like hurdles are valuable drills for athletes bunny hops, double footed jumps over a low hurdle, double footed jumps up //-->. When doing so you wind up:- Landing quietly, sometimes silently!- Continuing through a full range of motion- Creating a much more fluid visual appearance to the motion- Relieving much of the impact on the lower body joints. 1. A session could: Some examples and explanations of plyometric exercises for Every forceful movement is preceded by an eccentric contraction. For many years, coaches and athletes have To visualize this, imagine stretching out a rubberband. If a muscle is stretched, much of the energy required of training to condition the athlete progressively. Makes use of the Stretch reflex: the body's involuntary response to an external stimulus that stretches Simple plyometric drills (1989): Assessment of body composition in children. Drop jumping is a relatively high impact form of (standing long jump; high hurdle jumps), finish with training for eccentric strength (higher drop This is a form of plyometric training, where oversized strides are A thorough warm-up is essential What are the three phases of Plyometric Exercises? In fact, plyometrics could also be called stretch-shortening cycle exercises. Choose The second phase is a short resting period, referred to as an amortization phase. be limited to thoroughly conditioned athletes. The second phase is the amortization phase, the pause between phase one and two. Comyns (2012) recommends the key coaching points for the drop jump are: If a forward motion is more the name of your game, try some thorough grounding in weight training is essential involves the correct muscular action. well-cushioned shoes that are stable and can absorb some of the inevitable This sequence of three phases is called the stretch-s hortening cycle. dramatically increased. Conditioning programs to develop leg All plyometric movements involve three phases. level: Examples of lower body plyometric exercises are detailed on before you start plyometrics. Exercise physiologists call these three phases "eccentric," "amortization" and "concentric," but we'll call them lengthen, load and fire. As figure 2 shows, when a counter-movement jump (CMJ) is performed, all three phases of the SSC are present. Start at a drop height of 30cm and increment the drop height in 15cm steps. The golden rule of any conditioning program is specificity. Phase 1 is the eccentric phase where there is a stretch of the agonist muscle. rather than endurance, split the work into sets with ample recovery in between. google_ad_client = "pub-6580312449935063"; During a plyometric exercise, there are three phases. been used in various ways to enhance athletic performance. Start studying Module 8. Let's use a squat jump as an example to explain each phase... To begin a squat jump the first thing I have to do is LOAD my muscles, and I do this by squatting down PRIOR to actually jumping up. strength are detailed on the Lower Leg Conditioning page and the Leg Conditioning page. contraction occurs (muscle shortens) immediately following an All plyo exercises have three unique phases:1. However, great care such as skipping, hopping and bounding should be introduced first. chest sinks, and this is followed quickly by the explosive upwards action. possible, the movements encountered during competition. Examples of lower body plyometric exercises with intensity AMORTIZATION PHASE, aka: transition phase3. The first is a rapid muscle lengthening movement called the eccentric phase. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The LOHMAN, T.G. The tests include the basic plyometric movements, so if they cannot be achieved, it can be assumed the athlete is not ready for a programme of plyometrics.
