La pratique d’un sport ou d’une activité physique régulière doit faire partie de toute éducation compte tenu des impacts positifs sur la santé physique et psychologique.

Les enfants doivent pratiquer une activité physique de manière quotidienne et leur donner très tôt le moyen de pratiquer un sport est point important de leur éducation et une responsabilité des parents.

Par contre il est souvent difficile de choisir le sport en question ou à l’inverse de faire en sorte de ne pas choisir directement le sport pratiqué par les parents ou encore le sport que les parents ont toujours rêvé de pratiquer sans jamais y être arrivé.

Comment faire pour choisir le sport qui va convenir à votre enfant et qui semble lui plaire ?

C’est un choix qui n’est pas simple mais certains critères peuvent vous aider à bien choisir l'activité physique la plus adaptée à votre enfant.

Pourquoi un sport ?

Apprendre un sport, apprendre à faire de l'activité physique font partie d'une éducation réussie.

L’activité physique et donc le sport sont reconnus comme étant l’activité de référence pour se protéger des maladies chroniques. La pratique d’une activité physique quotidienne permet de réduire la fréquence de survenue des maladies cardio vasculaires, du diabète, de l’obésité de certains cancers, mais aussi de l’ostéoporose ou de la dépression.

La participation à des activités sportives et à des sports d’équipe aide les enfants à développer leur autonomie ; à mieux construire leur identité personnelle et à avoir une meilleure vision de leurs compétences. Le sport a toujours été un facteur d’intégration dans la société.

Il est de la responsabilité des parents d’aider leurs enfants à pratiquer un sport qu’ils ont si possible pu choisir dans un cadre collectif qui sera différent de celui de la famille ou de l’école.

La pratique d’un sport, au delà des effets physiques et physiologiques permettant de se protéger des principales maladies permet de développer des capacités cognitives essentielles dans sa vie personnelle et plus tard professionnelle :

  • - analyser une nouvelle situation à laquelle on vient d’être confronté,
  • - comprendre son environnement et prendre des décisions pour le faire évoluer s’il ne convient pas à la situation ou pire encore s’il vous met en danger
  • - prendre des responsabilités que ce soit personnellement mais aussi dans les sports d’équipe au nom du groupe
  • - réaliser des projets sur la base d’objectifs par exemple dans le cadre de programmes de compétitions. ,
  • - faire des choix en fonction des opportunités, des dangers auxquels on est exposé par exemple
  • L’ensemble de ces situations auxquelles le sport peut vous confronter participent largement au développement de la maturité de l’enfant.

BODY POSITION DRILLS

Because drag is an inherent part of the breaststroke, achieving excellent body position is essential in maximizing the forward motion of the stroke. Like freestyle and backstroke, the core is the center of power, but in breaststroke, there is no side-to-side roll, instead, there is a tipping or rocking type motion. Achieving an effective rocking motion requires the swimmer to maintain a stable hip position, while the head and legs switch back and forth between the extremes of the tipping float. The goal of the following drills for breaststroke body position is to learn to use core tension to achieve the best floating technique, while minimizing drag and maximizing glide productivity.

BODY POSITION DRILLS

The best butterfliers combine grace and power in what seems like effortless forward motion. The primary point of technique that these butterfliers share is good body position. While the line of the stroke is characterized by a wave or rocking motion, it is a stable, high hip floating position that is key to a good stroke. This position balances the stroke, and integrates the actions of both the upper and lower body. Often, swimmers attempt to achieve the rocking effect of the butterfly by folding both forward and back at the hips. Doing so eliminates core stability, lowers the hips, and eliminates balance in the stroke. It can also lead to back pain. The goal of the following drills for the butterfly body position is to develop a firm core, high hip body position for better balance and integration of butterfly actions.


 

Taking a Bow

THE PURPOSE OF THIS DRILL

  • Learning to stabilize motion using the abdominals
  • Isolating upper body motion
  • Using abdominal muscles to maintain a straight spine

HOW TO DO THIS DRILL

  1. Step 1 : - Stand with your head, back and legs against a wall, arms at your sides. Notice at the small of your back, you can fit your hand between the wall and your back. To achieve a truly firm core, you must straighten your spine, and eliminate this space at the small of your back. To do so, pull your belly button back toward your spine, and press the small of your back into the wall. Notice that to do this, you contract your abdominal muscles.
  2. Step 2 : - Maintaining your spine straight with contracted abdominals, press your chest forward away from the wall about six inches, as if taking a bow. Keep your hips and lower body firmly against the wall, controlling the speed of the movement. Hold this position for five seconds, stabilizing your position with your abdominal muscles.
  3. Step 3 : - Keeping your core firm, return your back to the wall. Check to see if you have maintained a straight spine by trying to fit your hand between the wall and the small of your back. Repeat the bow, actively using your abdominal muscles to maintain a straight spine, and to stabilize your upper body throughout the bow. Notice that your hips remain stable through the entire range of motion.
  4. Step 4 : - Now, try the same bowing action without the support of the wall. Maintain a straight spine. Keep your hips stable. Use your abdominal muscles to control the movement of your upper body, while your lower body remains still.

Two of the most common features of training pro­grams of swimmers competitive are the periodiza­tion of training volume and intensity and  the transition from training to racing.
A periodized train­ing and tapering program is based on the principle of overload—recovery—peaking.

This principle forms the basis of preparing swimming training programs with the aim of increasing the level of competitive performance.

A fundamental principle of preparing athletes is that periodization and tapering applies equally to all the different aspects of fitness, such as endurance, speed, strength, flexibility, and power. The training program must provide an overload (stimu­lus) to force the body to adapt to a previously un­encountered level of stress. After sufficient application of the stimulus (in terms of magnitude and fre­quency), a period of recovery and regeneration will allow residual fatigue to dissipate. If the processes of overload and recovery are managed correctly a pe­riod of super compensation will occur so that per­formance is elevated to a higher level for important competitions.

Periodization involves dividing the training plan into smaller parts using the terms mesocycle, macrocycle, and microcycle. These terms are used to establish a hierarchy of training within the overall program.

This approach is well established in practice in a wide range of endurance and power sports.

Mesocycle :

Mesocycle refers to a long-term training phase last­ing several weeks to months. In swimming this rep­resents the entire 12-20-week preparation for a ma­jor national or international competition. Most com­monly, there are two mesocycles a year with peaks for the national swimming championships and then the major international competition (e.g., Olympics, Worlds, etc.) held later in the year (luly-September).

One of the fundamental principles that underpins the periodization of training is that volume of train­ing is increased before the intensity of training. This principle applies to meso-, macro- , and microcycles alike. Most coaches are familiar with the concept that a foundation of aerobic fitness is established early in the mesocycle or competition season. After this initial period of increasing training volume to build endur­ance, the emphasis of training switches to the devel­opment of speed and anaerobic capacities. It is of­ten observed that this base level of fitness can be reestablished fairly quickly (4-6 weeks) in those swim­mers with an extensive training background. This has implications for older more mature swimmers who are returning after a break from training or competi­tion. However, it is much more efficient for swimmers to maintain a basic fitness program during the off-season.

The contemporary model of preparing competitive swimmers in a given year is based on the following se­quence of training and competition: preseason, early season, competitive season, taper, championship sea­son, and recovery or off-season. For highly trained swimmers the competitive season usually takes the form of domestic competition or international com­petitions.

The champi­onship season typically involves the national champi­onships, often doubling as the national team selection trials, and then the major international competition for that particular year.

Once the competition schedule has been estab­lished, the training plan can be prepared with the goal of maximizing the performance of the swimmer for the competitive and championship seasons. For in­ternational swimmers, the entire season is typically 44-48 weeks in length with a short break permit­ted after completion of the championship season. The length of each of the different training phases will vary according to the individual circumstances of the swimmer, team, and coach. In recent years, the international swimming calendar has become more crowded and as a consequence the annual train­ing plan has become more fragmented and com­plex.

Training by competitive swimmers typically consists of repeated bouts of shorter or longer intervals in a short-course or long-course pool. Intervals span a con­tinuum from longer slower intervals (50-1600 m for developing aerobic or endurance fitness) to shorter faster intervals (15-200 m for developing anaerobic or race pace qualities). The basic prescription of in­terval training can be simplified to four primary vari­ables: (i) the number of intervals or repeat efforts, (ii) the length/distance of the interval (15 m to con­tinuous swimming), (iii) the intensity (i.e., pace or velocity) of the interval, and (iv) the rest period be­tween intervals (variously formulated as the cycle time or rest period).

Preseason training commences from the low base of fitness maintained during the off-season. Swimmers typically start the preseason phase with a single ses­sion per day and gradually increase the number of ses­sions over the first few weeks. A graded increase sees the frequency of training increasing from one session per day, to three sessions over 2 days, and eventually to the traditional two sessions per day format followed by the majority of high-level swimmers.

The main features of the early-season phase are a mod­est training volume to start, small 5-10 km increases in volume per week, low initial training intensity, and dry-land conditioning including flexibility, circuits, weight training, and other games and activities, to im­prove the overall sport abilities of the swimmer. Af­ter several weeks there are further increases in train­ing volume, a graduai introduction of higher intensity aerobic work to the level of the lactate threshold, and emphasis on skill and technique development before moving to the faster training speeds.

In simple terms, training volume elicits improvements in general en­durance fitness while training intensity develops the specific fitness required for racing and competitive suc­cess. The later weeks of the early-season phase focus on continuing development of the lactate threshold (endurance fitness), maximal oxygen uptake (maxi­mal aerobic) and race pace training capacities, ongo­ing manipulation of training volume and intensity to maintain improvement, an individualized approach to volume, intensity and recovery, and refinement of skills particularly at race speeds.
