1. The training plan

The development of a football player and the preparation of a team are comparable to building a house. In order to achieve the objectives that have been set, the coaching staff have to follow a series of steps that have been scheduled as part of an overall plan.

This is known in the sporting world as the training plan.

The training plan consists of determining objectives and implementing a set of increasingly detailed procedures with the aim of achieving these objectives.

As with any form of education or teaching, as little as possible should be left to chance with training, even though a fair share of intuition, or “nous” on the part of the coach, also has its role to play in the process.The planning of his team’s training is therefore an essential task for any coach if he is to ensure that the play-ers progress, that their performance abilities develop, and that they are prepared both individually and as a team for competitive action. This is just as much a task for top-level coaches as it is for youth coaches.Why plan?

? To decide, after analysis and re? ection, on the choice of objectives to be achieved, both for the short and the long term.

? To help ensure a better weighting of the elements covered in the training, in terms of quantity, intensity and quality.

? To prevent improvisation in training work.

? To avoid routine and to give the coaching staff and players reassurance.

? To allow better monitoring of training and to facilitate evaluation.

? To allow the coach to respect and monitor the biological, physiological and psychological factors that determine performance.

Planning of training depends to a large extent on the age of the players, their level of development, the category of competition in which they are playing and the ? xture lists for the competitions in which they are involved. However, unlike in individual sports, such planning is not easy to schedule in a team sport like football, where players can be involved in several competitions (domestic league and cup competitions for their club, international club competitions and international competitions with the national team).

High-quality, methodical planning, such as that required by a national team, calls for close co-operation between the coach, the doctor, the dietician and the psychologist.

1.1 The annual training plan for the season

The annual training plan is the basis for all scheduled training activity, and the coach’s ? rst task is to draw

up this plan before a new season gets underway. This plan varies from country to country, either because

of the structure of the ? xture list of the competitions in a given country, or because of cultural, weather and

even ? nancial considerations. The plan does, of course, also vary, according to whether the coach is working

with top-level professional players or with young players who are still being developed. It does, however, rely

on the same methodological principles.

* Periodisation is a technique of planning the process of training and competition so that the annual training

plan is a succession of “periods”, each of which has a different style of activity.

For coaches working with players at the pre-development/pre-training stage or at the development stage,

the annual training plan is based around these same periods as well, but the scheduling of training activities

is not geared solely to team performances.

Irrespective of the results achieved by the team, the training objectives that have been set – regardless of

whether these are technical objectives, combined technical and tactical objectives or psychological and

physical objectives – must remain a priority throughout the season in the planning of training sessions.

2

Criteria to be taken into account when drawing up an annual training plan

? Playing level, performance age and training age

? The number of players (squad size) available

? The ? xture list

? The objectives for performance on the pitch for the season

? The infrastructure, equipment and conditions available for training

? The coaching staff available (coaches, medical support, administration manager, sports psychologist)

? Analysis and assessment of past performances

? Additional criteria to be considered:

? Sports medical tests

? Inclusion of preparation or recovery period

? The social environment of the players (family, place of residence, school, work, lifestyle habits, etc.)

The annual training plan is often subdivided into two or three large cycles (macrocycles), lasting four to six

months each, depending on the duration of the annual training plan.

a) The preparation period

? This is the key period for getting the players and the team as a whole in the right physical condition.

? It should last between 4 and 10 weeks (depending on the level of the players and the level of compe-

tition) and must take into account physiological factors. Experience has shown that the ? rst positive

effects of training become apparent after 6 to 10 weeks.

? A preparation period lasting 6 to 8 weeks seems to be the norm nowadays in football.

? The period is divided into two phases:

This period, which is subdivided into 3 or 4 cycles lasting 1 to 3 weeks each, is known as the preparation

mesocycle.

Table 1: Graph showing the relationship between the quantity and the intensity of training in an annual training plan b) The competition period ? The duration of this period depends on the competition schedule.? It usually lasts between 8 and 10 months (depending on the country and the level of competition).? The period is subdivided into weekly cycles called microcycles.? This is the period when general and speci? c ? tness are transformed into match ? tness: when players reach optimum performance capacity and seek to maintain this for as long as possible.? During this phase, the players’ need for competitive action is aroused and generated, and they are prepared for coping with the emotions and pressures of competing.? As the level of performance during this period depends on the commitment of the players in the various competitions and on their own personal potential, the coach has to bear in mind the need to take indi-vidual requirements into account in training.? To ensure the right emphasis in training and to allow the training to be monitored more easily, several of the microcycles in this period become 3 to 4-week competition mesocycles.In today’s game, given the heavy burden placed on players in terms of the number of matches played (many players are involved in at least two matches per week), it is necessary to programme recovery and regeneration cycles into the mesocycle, especially when working with young players.When players are being developed, learning mesocycles are always programmed into the schedule.Example:Three-week cycle with the main emphasis on technical aspects: receiving the ball, controlling

on the turn and delivering the ? rst pass. Together with the physical and competition-related

objectives ? xed, this emphasis on technical elements remains a priority in the cycle.

c) The transition period

? This is the period when the level of performance drops off and where the player has to be able to reco-

ver physically and mentally from the exertions of playing competitive football.

? The period lasts between 4 to 8 weeks (depending on the country and the level at which the players are

playing).

This phase is scheduled after a period of competitive activity. H owever, bearing in mind that 2 to 3

weeks’ absolute rest can be suf? cient to cause general endurance performance to drop by 20 to 25%,

VO2max by 4 to 6%, as well as causing a decline in overall strength and co-ordination qualities, it is also

possible to arrange a programme that allows the players to maintain their ? tness level with progressive

physical activity.

Example:– Phase 1, lasting between 7 and 14 days

After a few days’ complete break (this will depend on the player), introduce rest and recov-

ery with additional sports and activities (an excursion, cycling, swimming, tennis, etc.).

– Phase 2, lasting between 10 and 20 days

Special, individual programme, concentrating on endurance, suppleness and muscle

strengthening.

3 to

4 sessions each week, lasting 4

5 to 60 minutes at 60–70% of the intensity required

during the training phase.

This phase also allows players who have been out injured for a long period or on reduced training to re-

turn to performance level during the ? nal period of competition.

(Jens Bangsbo, 1994)

1.2 The competition microcycle

The microcycle, which is a short, weekly training cycle, stretches over several days and often a whole week.

The microcycle should not be merely a repetition of the previous cycle; it has to have a new foundation, and

this also implies that some of the processes, methods and forms of training have to be revamped as well.

There obviously also has to be a change with the workload in training.

Microcycles that are linked together over a 3 to 4-week period (thereby forming a mesocycle) can differ from

one week to the next. The content of the microcycle is often determined by the team’s result, but also by

other factors, such as the performance level of the team as a whole or of individual players, or the weather,

etc. It is always based on the exertion–recovery process. With young players at the learning stage, the micro-

cycle also has to take into account whatever learning objectives have been ? xed for the cycle.

At professional level, and even with young players who are playing international football, the high number

of matches – often 2 to 3 per week – makes it necessary to have 3 to 4-day microcycles that are essentially

geared to recovery and preparation for the next match.

The structuring of the microcycle – physiological and physical aspects

? Always de? ne the energy pathway that will form the physiological “focal point” of the session.

Example: Technical training with work on aerobic capacity (70–80%).

? Pay attention to the muscles/muscle groups and neuromuscular groups that are being used.

? Begin the cycle, as soon as the match is over, with active recovery based on oxygenation, capillarisation, cardiorespiratory endurance (basic aerobic endurance / aerobic capacity) and muscular endurance (mus-

cle strengthening).

? Work on strength, co-ordination and speed, but with emphasis on rest as well.

? The training “peak” (i.e. the most intensive training) should occur in the middle of the cycle.

? Stimulate muscle toning at the end of the cycle and on the eve of competitive activity (with work on reac-

tive speed, alactic speed and co-ordination).

? Ensure that the emphasis is correctly weighted in the cycle (quantity and intensity).

? Reduce the workload in the second part of the cycle.

? Plan the recovery and energy regeneration phases.

Example of a workout in a microcycle adjusted for football

? Match (it is also possible to hold a brief body and muscle “wake-up session” on the morning of the

match)

? Post-match wind-down, active recovery work (low-impact aerobic work)

? Strength (strengthening / power / plyometric work)

? Football / technical work / speci? c speed work (transformation work)

? Football / technical/tactical work / aerobic-anaerobic work (aerobic power)

? Aerobic endurance (recovery work, e.g. on a bike or another form of exercise)

? Rest period (possibly lasting 1 day and concluding the ? rst half of the microcycle)

? Football / explosive speed and/or speci? c speed work (multi-form)

? Football / technical/tactical work (preparation for the match)

1.3The training session

The training session forms part of the microcycle and lies at the heart of the weekly training plan. Each day,

the coach has to structure and plan his session around his objectives for that day, his medium and long-

term learning objectives, as well as taking into account the physiological, physical and mental strains on

the team. The training session has to be varied – not in respect of the objectives, but certainly as far as the

methods and forms of training to be used are concerned. It should last between 80 and 100 minutes in total,

depending on the type of session, the objectives and the training cycle.

The training session comprises three phases

a) The warm-up or limbering-up phase

This is the preparation part of the session. It has to be progressive, with an initial period of running and

varied movement, with or without the ball, and at a slow to moderate tempo to stimulate the body’s or-

gans and systems. This is followed by loosening up and co-ordination exercises; the tempo is then grad-

ually increased with exercises speci? cally adapted for football based on technical skills or on different

game situations. When working with young players, separate co-ordination and integrated co-ordinated

work with the ball must be included in the limbering-up phase.

There is nearly always a link between the content of the warm-up phase and the objectives set for the

performance phase.

This phase lasts between 15 and 20 minutes.

b) The performance phase

This is the main part of the session. During this period, the main emphasis is on training and instruction,

with clearly de? ned objectives. The content (games, drills and learning activities) has to be tailored to

the objectives, but it must come close to the real match situation. Correct emphasis has to placed on the

various training activities, not only as regards volume, but also the duration and intensity of the activi-

ties. Coaches must ensure that during recovery periods, which are usually active, the players use the ball

as often as possible; this is especially the case for young players.

At training/development level, but mainly at pre-training/pre-development level, the football played

must be at the heart of the whole training process. It should take up between 50% and 60% of the total

duration of the session, although the coach must also ensure that the players’ equip themselves with the

necessary technical, tactical and mental skills using progressive, analytical exercises. In training, play

improves when there is a better distribution between practice games on large and reduced-size pitches

and training exercises.

Example: Once the players have completed repeated drills and gone through simulated match situa-tions in a training exercise that focuses on shooting at goal, a small-sided game will help them

to put the ? nishing skills that they have worked on into practice. Shooting on goal should

therefore be included as a topic of emphasis in the practice game, thereby allowing the play-

ers to reproduce real match situations.

It is up to the coach to work out an optimum combination alternating between practice games, analytical

exercises and other forms of playing, or between separate forms of training without the ball and inte-

grated forms of training with the ball.

14

In this phase of acquisition and learning, the quality of the coaching (i.e. the commitment shown by the

coach, his ability to intervene in the right place and at the right time, the precision of the corrections that

he makes and his overall dynamism) will ensure active commitment on the part of the players and the

success of the training objectives set.

The duration of this phase varies. It generally lasts 50–60 minutes or up to 70 minutes, depend-

ing on the objectives, the day on which the session is being held, the weather conditions, local

customs, and even how the coach feels.

c) The cooling-down phase

This is the phase of physical and mental relaxation. It usually takes place on the pitch and includes some

light group jogging and limbering down and muscle-stretching exercises. The players then have hydra-

tion or energy drinks as the ? rst step to aid recovery.

This phase serves an educative purpose with young players as well, in that it teaches them about their

own well-being and how to respect their bodies. It is also the moment chosen by the coach to give his

assessment of the session, to ? x new objectives or simply to communicate with his players.

The duration varies between 10 and 15 minutes.

Tables 9 and 10 provide examples of training sessions.

1.4 Getting the emphasis right in training

Volume:All the efforts made by the players in training under exertion; the total quantity/duration of work done.

(e.g.: Volume of aerobic endurance work: 40 minutes)

Duration: Time taken for an action of physical exertion to be carried out at the required intensity with-

out rest.

(e.g.: Duration of the exercise: 15 minutes)

Intensity:The extent of the physical exertion, the tempo to be applied, the resistance to be overcome.

(e.g.: 80% of a maximum weight, 90% of maximum speed, 80% of MHR)

Repetition:The number of times that a physical exertion, an exercise or a learning activity is repeated.

(e.g.: 5 repetitions of 30m, 20 x abdominals, 10 x attacking play drills)

Set: Total number of repetitions performed at the same tempo.

Several repetitions form one set.

(e.g.: 5 (? ve) 30 metre-repetitions, 3 sets. 100% intensity; total distance: 450 metres

Muscular strength with squats, ten 80-kg repetitions, 5 sets)

Recovery: Time allocated for the recovery period.

Rest period taken between repetitions.

Rest period taken between sets (longer than that between repetitions).

The recovery phase is often an active period; it is dictated by the intensity,

the volume and the duration of the physical exertions undertaken.

基于单片机无线网络通信模块设计

前言 无线方案适用于布线繁杂或者不允许布线的场合,目前在遥控遥测、门禁系统、无线抄表、小区传呼、工业数据采集、无线遥控系统、无线鼠标键盘等应用领域,都采用了无线方式进行远距离数据传输。目前,蓝牙技术和技术已经较为成熟的应用在无线数据传输领域,形成了相应的标准。然而,这些芯片相对昂贵,同时在应用中,需要做很多设计和测试工作来确保与标准的兼容性,如果目标应用是点到点的专用链路,如无线鼠标到键盘,这个代价就显得毫无必要。 本无线数据传输系统采用挪威公司推出的工作于2.4频段的24L01射频芯片。与蓝牙和相比,24L01射频芯片没有复杂的通信协议,它完全对用户透明,同种产品之间可以自由通信。更重要的是,24L01射频芯片比蓝牙和所用芯片更便宜。系统由单片机32F103控制无线数字传输芯片24L01,通过无线方式进行数据双向远程传输,两端采用全双工方式通信,该系统具有成本低,功耗低,软件设计简单以及通信可靠等优点。

1. 总体设计方案 无线通信技术迅速发展,有多种通讯方案可供选择,这里从实用,经济和实现等方面进行综合的考虑分析,选出合适的设计方案。 1.1 无线通信方式的比较和选择 方案一:采用模块进行通信,模块需要借助移动卫星或者手机卡,虽说能够远距离传输,但是其成本较大、且需要内置卡,通信过程中需要收费,后期成本较高。 方案二:采用公司2430无线通信模块,此模块采用总线模式,传输速率可达250,且内部集成高性能8051内核。但是此模块价格较贵,且协议相对较为复杂。 方案三:采用24L01无线射频模块进行通信,24L01是一款高速低功耗的无线通信模块。他能传输上千米的距离(加),而且价格较便宜,采用总线通信模式电路简单,操作方便。 考虑到系统的复杂性和程序的复杂度,我们采用方案三作为本系统的通信模块。 1.2 微控制器的比较和选择 方案一:采用传统的89S52单片机作为主控芯片。此芯片价格便宜、操作简便,低功耗,比较经济实惠,但是应用很局限,且要求较高时传统的89S52单片机达不到要求。 方案二:采用公司生产的430F149系列单片机作为主控芯片。此单片机是一款高性能的低功耗的16位单片机,具有非常强大的功能,且内置高速12位。但其价格比较昂贵,而且是贴片封装,不利于焊接,需要制板,大大增加了成本和开发周期。 方案三:基于公司3内核的32F103系列处理器,采用串行单线调试和,通过调试器你可以直接从获取调试信息,从而使产品设计大大简化,主要应用于要求高性能、低成本、低功耗的产品。 根据系统需要,从性能和价格上综合考虑我们选择方案三,即用32F103作为本系统的主控芯片。 1.3 串行通信方式比较和选择 485串行通信:该接口是采用平衡驱动器和差分接收器的组合,抗噪声干扰性好。具有多机通信能力,这样用户可以利用单一的485接口方便地建立起设备网络。接口组成的半双工网络,一般只需二根信号线,所以它的接口均采用屏蔽双绞线传输,数据信
