Periodization is a cyclical method of planning and managing athletic or physical training and involves progressive cycling of various aspects of a training program during a specific period. [1] [2] Conditioning programs can use periodization to break up the training program into the off-season, preseason, inseason, and the postseason. Periodization divides the year round condition program into phases of training which focus on different goals.
The roots of periodization come from Hans Selye's model, known as the General adaptation syndrome (GAS). The GAS describes three basic stages of response to stress: (a) the Alarm stage, involving the initial shock of the stimulus on the system, (b) the Resistance stage, involving the adaptation to the stimulus by the system, and (c) the Exhaustion stage, in that repairs are inadequate, and a decrease in system function results. The foundation of periodic training is keeping one's body in the resistance stage without ever going into the exhaustion stage. By adhering to cyclic training the body is given adequate time to recover from significant stress before additional training is undertaken. The goal in sports periodization is to reduce the stress at the point where the resistance stage ends so the body has time to recover. In this way the exhaustion stage does not reduce the gains achieved, the body can recover and remain above the original equilibrium point. The next cycle of increased stimulus now improves the response further and the equilibrium point continues to rise after each cycle.
Selye (1957) labeled beneficial stresses as "eustress" and detrimental stresses as "distress". In athletics, when physical stress is at a healthy level (eustress), an athlete experiences muscular strength and growth, while excessive physical stress (distress) can lead to tissue damage, disease, and death. Periodization is most widely used in resistance program design to avoid over-training and to systematically alternate high loads of training with decreased loading phases to improve components of muscular fitness (e.g. strength, strength-speed, and strength-endurance). The Selye-cycles are similar to the "micro cycles" used at later times.
Russian physiologist Leo Matveyev and Romanian sport scientist Tudor Bompa expanded and further organized the periodization model. Matveyev is regarded as one of the first to demonstrate a formalized model of periodization around 1964. [3] He analysed the results of the Soviet athletes of the 1952 and 1956 summer Olympics and compared successful and not so successful athletes and their training schedules. [4] From these training plans periodized schedules were developed for the 1960 Olympics. With the success of the Soviet athletes, Matveyev's plans were spread all over the Eastern Bloc in their annual coordination meetings. [5] In the United States in 1979, J. Garhammer published one the first articles relating to periodization of strengthing training in athletes. Around that same time, James 'Doc' Counsilman, at the University of Indiana, talked about the periodization training that he has been using for years with swimmers. [6] [3]
In 1988, Grigori Goldstein, a Soviet defector shared information about periodization with American strength and conditioning coaches, including Johnny Parker. This information was published in the 2018 book The System: Soviet Periodization Adapted For the American Strength Coach. [7]
Periodic training systems typically divide time up into three types of cycles: microcycle, mesocycle, and macrocycle.
A macrocycle refers to a season of training in its entirety. It is an annual plan that works towards peaking for the goal competition of the year. [8]
There are three phases in the macrocycle: preparation, competitive, and transition. [9] The entire preparation phase should be around 2/3 to 3/4 of the macrocycle. The preparation phase is further broken up into general and specific preparation of which general preparation takes over half. An example of general preparation would be building an aerobic base for an endurance athlete such as running on a treadmill and learning any rules or regulations that would be required such as proper swimming stroke as not to be disqualified. An example of specific preparation would be to work on the proper form to be more efficient and to work more on the final format of the sport, which is to move from the treadmill to the pavement.
The competitive phase can be several competitions, but they lead up to the main competition with specific tests. Testing might include any of the following: performance level, new shoes or gear, a new race tactic might be employed, pre-race meals, ways to reduce anxiety before a race, or the length needed for the taper. When the pre-competitions are of a higher priority there is a definite taper stage while lower priority might simply be integrated in as training. The competitive phase ends with the taper and the competition.
Macrocycles are broken down into mesocycles and microcycles. [10]
A mesocycle represents a specific training block within your season, such as a strength building or endurance phase. [11] A mesocycle can also be defined as a number of continuous weeks where the training program emphasize the same type of physical adaptations, for example muscle mass and anaerobic capacity. During the preparatory phase, a mesocycle commonly consists of 4 – 6 micro-cycles, while during the competitive phase it will usually consist of 2 – 4 micro-cycles depending on the competition's calendar.
The goal of the plan is to fit the mesocycles into the overall plan timeline-wise to make each mesocycle end on one of the phases and then to determine the workload and type of work of each cycle based on where in the overall plan the given mesocycle falls. The goal in mind is to make sure the body peaks for the high priority competitions by improving each cycle along the way.
A microcycle is the smallest training set and typically lasts around a week. The main focus of a microcycle is a small focused block of training, such as two or three days of very hard training followed by the same amount of time for recovery. [12] Each microcycle is planned based on where it is in the overall macrocycle. [9]
A microcycle is also defined as a number of training sessions, built around a given combination of acute program variables, which include progression as well as alternating effort (heavy vs. light days). The length of the microcycle should correspond to the number of workouts - empirically often 4-16 workouts - it takes for the athlete or fitness client to adapt to the training program. When the athlete or fitness client has adapted to the program and no longer makes progress, a change to one or more program variables should be made.
The annual plan is important in that it directs and guides performance training over a year. It is based on the concept of periodization and the principles of training. The objective of training is to reach a high level of performance (peak performance) and an athlete has to develop skills, biomotor abilities and psychological traits in a methodical manner. [13]
This phase consists of the general preparation and specific preparation. This is a base creation phase with the objective to attain the previous training state, and the longest period of periodization must be devoted towards the preparatory period.
This phase may contain a few main competitions each containing a pre-competitive and a main competition. Within the main competition, an uploading phase and a special preparatory phase may be included.
This phase is used to facilitate psychological rest, relaxation and biological regeneration as well as to maintain an acceptable level of general physical preparation. This phase lasts 3–4 weeks (perhaps longer) but should not exceed five weeks under normal conditions and may be sports specific. It allows the body to fully regenerate so that it is prepared for the next discipline. [14] There are no competitions in this phase.
A review published in the journal 'Sports Medicine' in 2017 has questioned the validity of the use of traditional models of periodization in sport. This is largely due to the oversimplified assumptions put forward in the early development of periodization theory that are not always transferable to the psycho-biological effects of various training methods used in sport. [15]
Periodization has been questioned due to it being viewed as reductionist/deterministic. In coaching in particular it is oversimplified and doesn't take into account the true nature of coaching which is viewed as a dynamic, chaotic and forever changing environment. Periodization fails to consider the athlete, coach and the context of the coaching taking place. The improvement of an athlete or a team in sports varies depending on an individual's hormonal response, genetic predispositions, motivation, stress levels, as well as transient social and environmental variables.
Periodization is suggested to be the optimum method of sports training when aiming to enhance team performance due to the organisational and structural nature to its approach. Kiely (2012) states periodization provides benefits such as providing idealized training structures, times frames to progress athletes and therefore development and retention of overall fitness adaptations. However, within team sports, such as football, can be complicated due to the various training goals, volume of training and practices required as well as an extended season of competition – with reference to additional progressive competition matches (Gamble, 2006). This showing that periodization models can be difficult to implement in team sports due to its ever-changing nature, relating to why there are limited studies regarding the implementation of periodization in team sports.
For many years, football training and its planning has been (and still is) characterised by fragmented thinking of which has perhaps been attributed to the success of such an approach in individual sports. The emphasis of planning and improvement was mainly in regards to the physical attributes of strength, speed and endurance. [16] Furthermore, whether it be the undulating model, the reverse linear model or the traditional periodization framework, one of the underpinning assumptions is that it would be best to segregate the programme into distinct training blocks in a sequential hierarchy i.e. a training block to build endurance before speed and strength before power. This is claimed to be based on the 'science of periodization'. However, Kiely, [17] argues that the proof on which this is all based on is flawed because the studies used to build this proof have only 'compared training interventions with no training variation to those with degrees of variation' but did not offer any insight 'into how that variation is best scheduled and organised' (Kiely, 2010, p. 4). So although it is commonly agreed that training variation is an important design feature which needs to be integrated into the training plan, there is 'little or no supporting evidence' which proves that the segregation of the program into distinct training blocks or that there should be sequential hierarchy of how this should be done is in fact advantageous.
Many authors such as Garganta, Maia, & Marque, [18] Oliveira, [19] Castelo, [20] and Gaiteiro [21] have argued in regards to the indivisibility of the 4 components which make up a football performance...technical, tactical, physical and mental. This complexity makes football a multidimensional phenomenon which cannot be simply reduced to the sum of its parts. Is defending more important than attacking or vice versa? This question cannot be answered as football needs to be understood as a whole. As highlighted by Tamarit, [22] football is a tactical game where players are constantly required to make decisions in response to specific situations. So football needs to be viewed as a tactical game which encompasses with it the physical, technical and mental aspects required for positive performances. This is the foundation upon which Victor Frade developed a training methodology known as tactical periodisation which emphasises the development of the tactical dimension. Therefore, any physical, technical or mental development must always have a tactical intention. In other words, although the ability to run for 90 minutes may seem vital to play the game, knowing when, where and how to run is much more important.
Sports injuries are injuries that occur during sports, athletic activities, and exercising. In the United States, there are approximately 30 million teenagers and children who participate in some form of organized sports. Of those, about three million athletes 14 and under experience a sports injury annually. According to a study performed at Stanford University, 21 percent of the injuries observed in elite college athletes caused the athlete to miss at least one day of sport, and approximately 77 percent of these injuries involved the knee, lower leg, ankle, or foot. In addition to those sports injuries, the leading cause of death related to sports injuries is traumatic head or neck injuries.
An athlete is most commonly a person who competes in one or more sports involving physical strength, speed, power, or endurance. Sometimes, the word "athlete" is used to refer specifically to sport of athletics competitors, i.e. including track and field and marathon runners but excluding e.g. swimmers, footballers or basketball players. However in other contexts it is used to refer to all athletics participants of any sport. For the latter definition, the word sportsperson or its gendered sportsman or sportswoman are also used. A third definition is also sometimes used meaning anyone who is physically fit regardless of whether or not they compete in a sport.
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations, and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest along with a formal recovery plan.
In an organized sports league, a typical season is the portion of one year in which regulated games of the sport are in session: for example, in Major League Baseball the season lasts approximately from the last week of March to the last week of September. In other team sports, like association football or basketball, it is generally from August or September to May although in some countries – such as Northern Europe or East Asia – the season starts in the spring and finishes in autumn, mainly due to weather conditions encountered during the winter.
Endurance is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from and have immunity to trauma, wounds, or fatigue.
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.
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.
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.
General Physical Preparation, also known as GPP, lays the groundwork for later Specific Physical Preparation, or SPP. In the GPP phase, athletes work on general conditioning to improve strength, speed, endurance, flexibility, structure and skill. GPP is generally performed in the off-season, with a lower level of GPP-maintenance during the season, when SPP is being pursued. GPP helps prevent imbalances and boredom with both specific and non-specific exercises by conditioning the body to work.
Sports nutrition is the study and practice of nutrition and diet with regards to improving anyone's athletic performance. Nutrition is an important part of many sports training regimens, being popular in strength sports and endurance sports. Sports nutrition focuses its studies on the type, as well as the quantity of fluids and food taken by an athlete. In addition, it deals with the consumption of nutrients such as vitamins, minerals, supplements and organic substances that include carbohydrates, proteins and fats.
Endurance training is the act of exercising to increase endurance. The term endurance training generally refers to training the aerobic system as opposed to the anaerobic system. The need for endurance in sports is often predicated as the need of cardiovascular and simple muscular endurance, but the issue of endurance is far more complex. Endurance can be divided into two categories including: general endurance and specific endurance. Endurance in sport is closely tied to the execution of skill and technique. A well conditioned athlete can be defined as, the athlete who executes his or her technique consistently and effectively with the least effort. Key for measuring endurance are heart rate, power in cycling and pace in running.
Athletic heart syndrome (AHS) is a non-pathological condition commonly seen in sports medicine in which the human heart is enlarged, and the resting heart rate is lower than normal.
In sports science theory, supercompensation refers to the post-training period during which the trained parameter has a higher performance capacity than it did prior to the training period.
In sports, tapering is the practice of reducing exercise in the days just before an important competition. Tapering is customary both in endurance sports, such as long-distance running and swimming, and strength sports, such as weightlifting and sprinting. For many athletes, a significant period of tapering is essential for optimal performance. The tapering period frequently lasts as much as a week or more. This tapering means gradually reducing the exercise over a short period of time then stopping completely when leading up to competitions.
A training camp is an organized period in which military personnel or athletes participate in a rigorous and focused schedule of training in order to learn or improve skills. Athletes typically utilise training camps to prepare for upcoming events, and in competitive sports, to focus on developing skills and strategies to defeat their opponents. A military training camp generally refers to the period of boot camp, or further or refresher training.
Athletics is a term encompassing the human competitive sports and games requiring physical skill, and the systems of training that prepare athletes for competitive performance. Athletic sports or contests are competitions which are primarily based on human physical competition, demanding the qualities of stamina, fitness, and skill. Athletic sports form the bulk of popular sporting activities, with other major forms including motorsports, precision sports, extreme sports and animal sports.
A critical skills operator (CSO) is a United States Marine in the primary special operations career field of the United States Marine Forces Special Operations Command (MARSOC). CSOs, colloquially known as "Raiders", are awarded the Military Occupational Specialty 0372. CSOs are assigned to Marine Special Operations Teams (MSOT), Companies (MSOC) and Battalions (MSOBs). CSOs are trained to execute a variety of missions. Specialized training also provides capabilities in language fluency necessary for crossing cultural barriers, allowing CSOs to connect with local forces and civilians. It takes, at a minimum, four and a half years to create a Marine CSO; a Marine must have served a minimum of three years or achieved the rank of at least lance corporal before being considered a MARSOC candidate.
Margo Jennings is a retired teacher and athletics coach. Jennings enjoyed a 40-year teaching career while coaching track athletes of all levels for 30 years. Using her self-created training plan, focusing on low mileage and strength training, Jennings coached many athletes, most notably Maria Mutola (Mozambique), who won Gold in the 800m at the 2000 Sydney Olympics and Dame Kelly Holmes (England) who won double gold in the 800/1500m events at the 2004 Athens Olympics. Jennings is considered by many supporters as one of the best middle distance running coaches in the world.
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.
Competitive cross-country skiing encompasses a variety of race formats and course lengths. Rules of cross-country skiing are sanctioned by the International Ski Federation and by various national organizations. International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games. Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing. It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation. Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment.
