NUTRITION “We are whatweeat” P.E. teacher: Narciso Marín
Choose a widevariety Eatalltypes and choosehighfibrekindswheneveryou can Chooselowerfatalternativeswheneveryou can Chooselowerfatalternativeswheneveryou can Try nottoeattoooften, and havesmallamounts P.E. teacher: Narciso Marín
Diet • Definition: “The normal foodweeat” • Howeverthere are alsospecialdiets: • To lose weight • Togainweight • Dietsbecause of moral values (vegetarian) • Because of foodallergies P.E. teacher: Narciso Marín
Calories • Foodenergyiscommonlymeasuredusingcalories. • A calorie (cal) isdefined as theenergyneededtoraisethetemperature of 1 gram of waterby 1 degree. • A kilocalorie(kcal) es theenergyneededtoraisethetemperature of 1 kilogram of waterby 1 degree. Regardingtodietsornutritionwe use kilocalories (kcal) P.E. teacher: Narciso Marín
Energy balance Energy balance meanstaking in and using up equalnumber of kilocalories • 15 to 18 yearsoldmalesneed 2755 kcal/day • 15 to 18 yearsoldfemalesneed 2110 kcal/day P.E. teacher: Narciso Marín
Threemethods of losingweight Thethirdmethodgivesbestresults and isthemostlonglasting P.E. teacher: Narciso Marín
Overweight, overfat, obese P.E. teacher: Narciso Marín
Factorsaffecting a sportsperson’sdiet • Natural bodybuild • Particular sport • Specific rol P.E. teacher: Narciso Marín
Thesevenfactors of a balanceddiet • Whycarbohydrates? • Whyfats? • Whyprotein? • Whyvitamins? • Whyminerals? • Whywater? • Whyfibre? P.E. teacher: Narciso Marín
1. Whycarbohydrates? • Theymantainourbody’senergystores. • Muscles and liverstoreglycogen, thatisquicklyconvertedintoglucosetobeusedbymuscles and otherorgans. • Twotypes: • Sugars • Starch: bread, pasta, potatoes and rice • Theyshouldformabout 47 % of ourdailyenergy P.E. teacher: Narciso Marín
2. Whyfats? • Theyprovideenergy and helptomakeotherthingswork (fat-soluble vitamins) • Types: • Saturatedfats: animal fats and oils • Polyunsaturatedfats: fish, margarine… • Monounsaturatedfats: red meat, nuts… • No more than 30% of dailyintake. P.E. teacher: Narciso Marín
3. Whyprotein? • Mainaim: • bodybuilder in respect of muscles • repairer of damagedtissue. • It can alsoprovideenergy (15%). Itwouldbeconsideredanimportantsource in the case of poornutrition. • Excessprotein can beconverted and stored as fat • Proteinsources: animal and vegetable proteins. P.E. teacher: Narciso Marín
4. Whyvitamins? • Weneedthemfor: • Goodvision • Goodskin • Red bloodcellformation • Healing • Healthybones and teeth • Bloodclotting • Twogroups: • Water soluble • Fat soluble P.E. teacher: Narciso Marín
5. Whyminerals? • Calcium • Formation and maintenance of bones and teeth. • Iron • Veryimportantbecause of its link withhaemoglobin and itseffectontheoxygen-carryingcapacity of theblood, and the red bloodcellsformation P.E. teacher: Narciso Marín
6. Whywater? • Becauseitis a means of transportfor: • Nutrients • Waste • hormones • Becauseitholdsoxygen • Becauseitcontrolsthedistribution of electrolytes • Becauseitcompensatesdehydrationwhenpractising sport • Becauseitcontrolsbodytemperature P.E. teacher: Narciso Marín
7. Whyfibre? • Important in thefunctioning of thedigestivesystem • Itpreventsconstipation P.E. teacher: Narciso Marín
Someusefulnutritional ideas • Re-fuel: don’tneglectyourmeals • Emphasizethecomplexcarbohydrates • Reduce yourintake of fat • Drinkplenty of water and fruitjuice • Keepto a balanceddiet, and exercise P.E. teacher: Narciso Marín
Energy and sportsactivity • For short duration and highintensityexercise: energywill come fromcarbohydrates • For a longerduration (up to 2 hours) and moderateintensity: energywill come fromequalamounts of carbohydrates and fat. • For a longduration and higherintensity (marathon): energyderivedfromfatstoreswillincrease. P.E. teacher: Narciso Marín
TRAINING “Tobefitornottobefit… that’sthequestion” P.E. teacher: Narciso Marín
Effects of regular training and exercise P.E. teacher: Narciso Marín
Long-termbenefits of exercise • It reduces therisk of coronaryheartdisease (CHD) • Theheart: itincreases in size, thickness and strength, so it can workharderforlonger. • Theheartbeatsfewer times, so itwillbelessstressed P.E. teacher: Narciso Marín
Aerobic activity • Aerobic fitness: theabilitytoexerciseor compete, for a long time, at a levelthatallowstheresperiatorysystemto cope physiologically (withoutgettingbreathless) • Waystoimprove aerobic fitness: • Continuousrunning • Interval training • Fartlek training • Circuit training P.E. teacher: Narciso Marín
Anaerobicactivity • Abilitytowork at a highintensityfor a short period of time and thentorepayyourrespiratorysystemaftercompletingthe training sessionorcompetition. • During anaerobic (without oxygen) work, involving maximum effort, the body is working so hard that the demands for oxygen and fuel exceed the rate of supply and the muscles have to rely on the stored reserves of fuel. The muscles, being starved of oxygen, take the body into a state known as oxygen debt and lactic starts to accumulate in the muscles. P.E. teacher: Narciso Marín
Theprinciples of training P.E. teacher: Narciso Marín
Systematic training for individual needs, and specificity • Itisimportantthatthe training programmeshouldbesystematicorplanned. • Itshouldalsobecreatedtofit individual needs: time, motivation, kind of training, etc. • Relatedwithsomethingoraspectyouwish, todevelopyouemphasizethatspecificaspect in yourprogramme P.E. teacher: Narciso Marín
Overload • Training in a worthwhilerangeorintensityabovetheminimumamountrequiredtoimprovefitness, theminimumthreshold of training, and belowthemaximumthreshold of training. Image in nextslide P.E. teacher: Narciso Marín
Adaptation • The body will react to the training loads imposed by increasing its ability to manage those loads. • Adaptation occurs during the recovery period after the training session is completed. If exercises lasting less than 10 seconds (ATP-CP energy system) are repeated with a full recovery (approximately 3 to 5 minutes) then an adaptation in which stores of ATP and CP in the muscles are increased. If overloads are experienced for periods of up to 60 seconds, with a full recovery, it is found that glycogen stores are enhanced. P.E. teacher: Narciso Marín
Supercompensation • Speed: 8-24 hours • Soft aerobic workout: 10-14 hours • Medium aerobic workout (150-170 bpm): 24-36 hours • Musclestrength and anaerobicworkout: 48-72 hours P.E. teacher: Narciso Marín
FITT principle P.E. teacher: Narciso Marín
Regularity and moderation • Mostbenefitisgainedfrom training on a regular basis • Moderation: gettingtheright balance betweennot training enough and training toomuchorover training. P.E. teacher: Narciso Marín
Progression • Increasinggraduallyyour training programme: • Training more often (frequency) • Training more setrenuously (intensity) • Spendinglonger (time) • Or a combination of suchfactors. P.E. teacher: Narciso Marín
Reversibility • Ithappensifless training takes place, orifthe training sessions are madeeasier. • Thatistheopposite of progression, sincetheathlete loses fitness. • Itusuallyhappenswhentheathlete has sufferedaninjuryfor a long time. P.E. teacher: Narciso Marín
Methods of training P.E. teacher: Narciso Marín
Interval training • Thismethod can beusedfor a greatvariety of sports (individual and collective) • Workinterval: • Itmaybe a distance (60 m) or a time torun (10 sec) • Restinterval: • Itmaybe a walk back tothestartingmarkornotworking (rest) P.E. teacher: Narciso Marín
Advantages of interval training • Itincludesrepeatedspreintrunningorswimming, whichisanaerobic. • Ittakes place over short periodsorbursts. • Itincludes a restperiod (interval) whichallowsforrecovery. • Itincludesrepetitions of highquality, whichraisesthe pulse tonearmaximal. P.E. teacher: Narciso Marín
Continuous training • Itisthemostappropiate training toimprove cardiovascular endurancefor a sedentaryadult. • Itcouldstartwithbriskwalking and graduateto jogging. • Over a distanceor a time. P.E. teacher: Narciso Marín
Advantages of continuous training • Itisverycheap. • You can workonyourownorwith a group. • Itissuitableforhealth and fitness. • Itimproves aerobic fitness. • It can take place in a variety of places. • It can beadpatedto suite individual needs. P.E. teacher: Narciso Marín
Fartlekrunning • Itis a combination of fast and slowrunning. • Itisheld in thecountryside, totakeadvantage of slopes. • So youhavesprints and jogs, orperiods of workfollowedbyperiods of rest. P.E. teacher: Narciso Marín
Advantages of fartlekrunning • It can be done in a variety of terrain. • It can includehillwork (uphill and downhill) • It can includerepetitions and programmes are very flexible. • Restperiods can beincludedorthesession can becontinuouswithintermittenthard and easyrunning. P.E. teacher: Narciso Marín
Cross training • Mixture of training oftenusedto break up themonotony of a single type of training. • ADVANTAGES OF CROSS TRAINING • Itmakes training more interesting. • You can trainwithdifferntpeople in differentactivities. • Certainmusclegroups can berestedfromdaytoday. • Training can beadaptedtoweatherconditions. P.E. teacher: Narciso Marín
Circuit training • Number of exercises, set out so thatyouavoiexercisingthesamemusclegroupconsecutively. • Aim: • toimprove local muscular endurance • cardiovascular fitness • Curculo-respiratoryfitness P.E. teacher: Narciso Marín
Advantages of circuit training • Itoffers more general all round fitnessthantheotherthreemethods. • Itincludesstrength, endurance, power, flexibility and speed. • People of alllevels of fitness and ability can takepart. • Itincludes aerobic and anaerobicactivities. • Widerange of exercises. • It uses theoverloadprinciple of training.
