Introduction One of the most common discussion topics among swimming coaches is tapering for important competitions. The concept of tapering is a legacy of an outmoded training model that is gradually being replaced as coaches embrace periodized training principles. However, that comment aside, there still is a need in many swimming pools for swimmers to recover from extensive periods of general and specific fatigue so that all the body's resources can be applied to competitive events. The coaching strategy of working athletes hard and keeping them fatigued for many months was shown to be useful in the days when training usually did not fully stimulate or tax the physical capacities of individuals. As "hard work" seemed to pay off, coaches logically assumed that if hard work produced desirable results, more and harder work would produce even better results. In swimming, and indeed in sports in general, that approach has been taken to extremes and no longer is supported by research evidence or the practices of very successful coaches and athletes. The underlying belief that has been touted among swimming coaches is: although swimmers are always tired, training hard, and performances are not changing or are even getting worse, good things are still happening to them. That is a false belief. Better swimmers come from stepped-improvement programs, with demonstrable training effects being derived from the judicious use of work and recovery throughout the year. The introduction of a taper period prior to competitions is essential when the training program experienced has been of the "old" format. Even if a coach still believes in the "always keep them tired and then taper" approach, there are actions which can be taken that will go a long way to maximize the investment in training. Most taper programs consider a few changes in programming. There are more variables which will produce even heightened benefits over "simple" tapers. The purpose of this Bulletin is to summarize what is known about traditional tapering and how that knowledge can be applied to enhance the prospects of serious swimmers achieving performance goals at important competitions. Basic Assumptions There are two basic research findings which should govern the underlying considerations for developing a taper program.
These two principles set the basic guidelines for tapering; (a) allow rest and recovery to occur fully without confounding the procedure with the irrational fear that conditioning will be lost, and (b) perform specific performance tasks that will replicate the demands of the intended competitive effort and competition conduct. A modern interpretation of why tapering works is that only neuromuscular and psychological factors recover (Rushall & Pyke, 1990, p. 69; Wilmore & Costill, 1988, p. 198). There is little to no change in physiological status. What happens in a taper is that neural and cognitive capacities increase in use efficiency. Strength and power (neuromuscular functions) increase markedly, and the propelling efficiency of strokes (largely a cognitive recovery function) also increases. For these reasons, it is futile to attempt to get extra physiological capacities during a taper. Its programming should allow neural and cognitive performance factors to recover and become more finely tuned. Factors To Be Considered Length of Time Research at the International Center for Aquatic Research (Rushall, 1992; Troup, 1990) has shown the maximum length of a taper to be three weeks, with the possibility of it being extended to four weeks. There are a number of factors which modify the actual length.
As an example of the above, the following is quoted from Rushall and Pyke: Only a small amount of training overload is necessary to maintain fitness once a high level has been attained. . . . Another example of the ability to maintain peak fitness over a lengthy period without being involved in large amounts of hard training was shown in the performances of the Russian national swimming team in 1978. After performing creditably against the East German team, the Russians traveled to the USA and two weeks later recorded a number of Russian national records. They were achieved without any volumes of demanding training between the two competitions. The same team then traveled to Canada and 10 days later set 17 Russian records. Those improvements in performances were achieved without returning to sustained hard training. It seemed that the stimulating effects of hard competitive efforts and reduced interim training were sufficient to maintain previously attained levels of fitness. After a high level of fitness has been developed, the same amount of hard training is not necessary to maintain those peak fitness levels. A reduction in training frequency, but not intensity, to about one third is considered suitable for maintaining endurance capacity. It is suggested that even greater reductions could be tolerated for strength and power activities. (pp. 56-57) Taper effects can be extended by the judicious use of quality training stimuli on a maintenance training schedule. Work Volume The volume of work should be reduced to at least 60% of that which existed during heavy training (Troup, 1990). However, for programs that have had excessive volumes of training (e.g., 11 sessions per week, 12 km per day) the reduction could be to a level as little as 30% to maintain aerobic adaptation but that value would be too low to retain power (Neufer, Costill, Fielding, Flynn, & Kirwan, 1987). The principle of individuality has to be considered as a major moderating variable for determining the appropriate length of the training volume reduction. Higher volume training in the immediate days preceding an event may be detrimental to performance while a slow decay in volume will have a beneficial effect on maximizing competition preparation (Zarkadas, Carter, & Bannister, 1994. Some form of consistent performance measurement on at least an alternate day schedule can be performed without any undue effect on ensuing competitive performances. Times should be expected to gradually improve as a taper progresses. An example of a measurement set would be a broken 200 IM for a 200 IM swimmer. Split and accumulated times should improve in each repeated "test set." For a taper, training volume should be reduced to 60% of normal heavy training volume. The nature of the volume reduction should be by session. Eleven training sessions a week should be reduced to six or five (Houmard & Johns, 1994). It is erroneous to continue an excessive number of sessions while performing smaller training session loads. Some reasons why sessions should be reduced are: (a) the sessions off allow for greater recovery and energy restoration, (b) the added rest time allows stresses from sources other than swimming to be tolerated, and (c) there is a greater potential for restorative sleep to occur. Morning sessions should be eliminated. Their removal allows a circadian rhythm that better matches the competitive program to be established. Since swimmers perform better, that is, they are stronger and more enduring, in the late afternoon (Reilly & Marshall, 1991), it is advisable to retain late-day sessions rather than mornings. The number of training sessions should be reduced in a taper rather than reducing session loads. The way the volume decrease should occur is not clear. Houmard and Johns (1994) after reviewing the literature concluded that an incremental, stepwise was preferable. However, Troup (1990) showed that neither a sudden nor gradual reduction over a three week period appeared to be more related to ultimate performances. It was suggested that tapering really only allowed recovery and that the final performances were related more to the type of training that preceded it rather than what was done in the taper itself. This is a plausible explanation. It is hard to imagine how a few isolated events that occurred during a taper would be strong enough to override the conditioned strength of responses developed through very extended periods of demanding training requiring specific adaptations. The major purpose of a taper is to allow athletes to recover from various forms of fatigue. Type and Intensity of Work The most important variable for influencing competition performance is the specificity of work that precedes the taper (Rushall & Pyke, 1990). That work should: (a) be of the same pace as the anticipated performance level so that biomechanical patterns can be refined under varying levels of fatigue, (b) be of the same energy demand ratio (aerobic:anaerobic) to that demanded in each event, and (c) require the same psychological control functions that will be needed in each race. If a swimmer has several events, then each should be trained for specifically. A taper should continue specific training stimuli and should eliminate all non-specific demanding training experiences. Doing other activities in taper is a waste of time and may impede recovery benefits (Houmard, Scott, Justice, & Chenier, 1994). There is no support for any form of cross training in taper. Irrelevant training (e.g., slow swimming, kicking, use of swimming paddles, flippers, etc.) should only be used to provide variety and low-demand recovery activities. During a taper, the body should become highly sensitized to the specific qualities required for targeted events and desensitized to irrelevant activities. That desensitization is important. When a swimmer is tired in a race, the body has to determine which established forms of activity will be recruited to assist in performance maintenance. If there are slow-swimming patterns that are high in conditioned strength, they will be recruited and performance will suffer. If the body only knows fast-swimming patterns, then its selection options are limited to them and consequently, fast swimming will be maintained. The activities programmed in the taper should always reinforce race-specific movement patterns and energy use. There are principles that govern the quality of pace work conducted in a taper (Troup, 1992).
The work performed in a taper should either be race-specific quality or of a recovery nature. With respect to the need to train specifically earlier than the taper period, Costill, Thomas, Robergs, Pascoe, Lambert, Barr, and Fink (1991) made the following comment: . . . our knowledge of the need for specificity in training might lead us to assume that such training may not provide the adaptations needed for optimal swimming performance. Since the majority of the competitive swimming events last less than 3 min, it is difficult to understand how training at speeds that are markedly slower than competitive pace for 3-4 hr/day will prepare the swimmer for the supramaximal efforts of competition. (p. 376) A taper will allow the specific training effects that have occurred, particularly in the late specific preparatory and pre-competition training phases, to emerge. The continuing of only race-specific training will heighten an athlete's and the body's awareness of the qualities of race requirements. That heightened sensitivity will increase the consistency of competition performance quality. Race-specific training sets have been described in the first three editions of the ICAR annual reports and the NSWIMMING Coaching Science Bulletins over the past six months. The exact sets that yield specific skill and energy benefits which have been determined and are listed below.
Physiological Effects Houmard and Johns (1994) summarized physiological effects which have been studied along with the taper phenomenon.
Psychological Content It is too late to attempt to correct any physically conditioned state or biomechanical flaw during a taper. It is detrimental to institute a short period of intense quality training in the belief that a "little more" physical capability will be developed. The only option for training during a taper is specific work that yields positive affirmations of an athlete's readiness. Psychological factors are the major ingredients of performance that can be changed and improved during a taper.
Since no further biomechanical or conditioning changes should be attempted in a taper, it should emphasize psychological activities and effects to maintain the seriousness of application and focus of swimmers. Recovery Recovery should be emphasized during a taper: (a) complete recovery should occur between training sessions, and (b) athletes should be taught recovery activities that can be used between races and sessions at competitions.
Activities that assist recovery between races and competitive sessions/days should be planned and practiced during the taper period. Factors Which Moderate Taper Effects There are a number of factors that also moderate the effects of a taper and warrant adjustments in planning.
Self-questions a Coach Should Ask A taper period and competition preparation phase are stressful for athletes but often more stressful for coaches. Heightened self-monitoring by coaches of their decisions, programs, and actions should occur. Radical alterations in behavior can signal panic to swimmers which, in turn, could destroy their confidence and self-efficacy. To ensure that the coach is a constructive rather than inappropriate model, the following considerations should be contemplated daily.
Implications The taper has traditionally been given more credit than it deserves for effecting performance. It primarily is a period that allows recovery, restitution, specific practice refinements, and planning of competition behaviors. What will be exhibited in races are the beneficial effects of EXTENSIVE training that was experienced prior to the taper. The psychological activity and state of the athlete becomes increasingly more important as the taper progresses and should be the primary focus of the program. It is incorrect to think that skills can be altered in any beneficial manner or that extra physical condition can be gained by short bouts of intense training. When a taper is started, it is too late to consider any biomechanical or physiological change training. As the taper progresses, indications that performance is improving and that competition conduct activities are being practiced will have beneficial effects on the athlete's psychological state. If events are predictable, practiced, and accompanied by a self-efficacy of performance excellence, then a successful competition is likely (Houmard & Johns, 1994). The role of the coach as the model of seriousness, control, planning, and professional competence is important for athletes to witness if they are expected to perform in a similar manner. Positive and constructive coaching exhibiting a capacity to cope with any problem in a competent manner will contribute to athletes believing that all conditions exist for them to perform well.
