Q & A

  • What are the two types of muscle fibers that our muscles are composed of?

    -Our muscles are composed of two types of muscle fibers: fast-twitch and slow-twitch fibers.

  • How does the ratio of fast-twitch to slow-twitch muscle fibers determine an individual's suitability for certain sports?

    -The ratio of fast-twitch to slow-twitch muscle fibers determines an individual's natural athletic abilities, with more fast-twitch fibers being beneficial for explosive, short-duration sports, and more slow-twitch fibers being advantageous for endurance sports.

  • What are some examples of sports that would benefit from having a higher proportion of fast-twitch muscle fibers?

    -Sports such as sprinting, weightlifting, BMX racing, and high jumping would benefit from having a higher proportion of fast-twitch muscle fibers due to their explosive and power-intensive nature.

  • What is the disadvantage of having predominantly fast-twitch muscle fibers?

    -The disadvantage of having predominantly fast-twitch muscle fibers is that they fatigue more quickly and cannot sustain activity for as long as slow-twitch muscle fibers.

  • Why are slow-twitch muscle fibers more prevalent in athletes like marathon runners and triathletes?

    -Slow-twitch muscle fibers are more prevalent in marathon runners and triathletes because they have a higher endurance capacity, allowing for sustained energy production over longer periods.

  • How does the presence of mitochondria in slow-twitch muscle fibers contribute to their function?

    -The presence of more mitochondria in slow-twitch muscle fibers allows them to produce energy for a much longer time compared to fast-twitch fibers, making them ideal for endurance activities.

  • What was the traditional method used to measure an individual's muscle fiber type, and why was it considered unpleasant?

    -The traditional method involved taking a muscle biopsy, which involved cutting a piece of muscle from the athlete's leg using a needle. It was considered unpleasant due to the pain involved and the fact that it was not entirely representative or accurate.

  • How does the new, non-invasive method developed by Eline Lievens measure muscle fiber type?

    -The new method involves placing an athlete under an MRI scanner and measuring the muscle fiber type based on the signal from the entire body, providing a much larger sample size and a more accurate representation without causing pain or requiring recovery from an injury.

  • Is it necessary for every young athlete to undergo an MRI scan to determine their muscle fiber type?

    -No, it is not necessary for every young athlete to undergo an MRI scan. The scan is more relevant for aspiring top athletes who wish to understand their strengths and weaknesses to potentially excel in a specific sport.

  • How can knowing one's muscle fiber type influence training and competition strategies?

    -Knowing one's muscle fiber type can help tailor training programs to the individual's natural abilities, allowing for more effective use of their strengths and mitigating the risk of injury. It can also inform tactical decisions during competitions, such as pacing and energy management.

  • What is the significance of the muscle fiber type in determining how an athlete should train and compete?

    -The muscle fiber type is significant as it can indicate whether an athlete is naturally more suited to explosive or endurance activities. This knowledge can be used to optimize training routines, recovery periods, and competitive strategies to maximize performance and reduce the risk of injury.

  • Why might a 'one-size-fits-all' approach to coaching not be the most effective strategy?

    -A 'one-size-fits-all' approach to coaching may not be effective because it does not take into account the individual muscle fiber types and their corresponding needs. Athletes with different muscle fiber compositions may require different training intensities, durations, and recovery times to perform optimally.

Keywords

💡Fast-twitch muscle fibers

Fast-twitch muscle fibers are a type of muscle fiber that can contract quickly and powerfully, but they fatigue more rapidly than slow-twitch fibers. They are essential for explosive movements like sprinting or weightlifting. In the video, it is mentioned that athletes like Lukaku, a fast football player, likely have a high proportion of these fibers, which is why they are suited for their sport.

💡Slow-twitch muscle fibers

Slow-twitch muscle fibers are another type of muscle fiber that can contract more slowly but are more resistant to fatigue. They are prevalent in endurance athletes like marathon runners and triathletes. The video explains that these fibers contain more mitochondria, which allows them to produce energy for longer periods, making them ideal for sustained physical activity.

💡Genetics

Genetics refers to the hereditary factors that determine traits, such as muscle fiber composition. The video emphasizes that the ratio of fast-twitch to slow-twitch muscle fibers is largely genetically determined, and while training can influence this to some extent, it cannot drastically change the inherent genetic makeup of an individual's muscles.

💡Muscle fiber testing

Muscle fiber testing is a method used to determine the composition of an individual's muscle fibers. The video discusses an old, invasive method that involves taking a muscle biopsy, which is both painful and not entirely representative. Eline Lievens, a movement scientist featured in the video, has optimized a new, non-invasive method using MRI scans that can measure muscle fiber types without causing pain or requiring recovery from an incision.

💡MRI scan

An MRI (Magnetic Resonance Imaging) scan is a non-invasive medical imaging technique that uses a magnetic field and radio waves to create detailed images of the inside of the body. In the context of the video, MRI is used to measure muscle fiber types without the need for a muscle biopsy. This method is highlighted as being more accurate and less painful, allowing for a larger area of muscle to be assessed.

💡Endurance sports

Endurance sports are physical activities that require prolonged exertion and stamina, such as marathon running and triathlons. The video relates endurance sports to the presence of slow-twitch muscle fibers, which are capable of sustained energy production, making them ideal for these types of sports.

💡Explosive sports

Explosive sports involve short bursts of high-intensity activity, such as sprinting or weightlifting. The video connects explosive sports to the presence of fast-twitch muscle fibers, which are necessary for powerful and quick muscle contractions.

💡Optimal training

Optimal training refers to a customized approach to physical training that takes into account an individual's specific muscle fiber composition. The video suggests that a 'one-size-fits-all' training approach may not be ideal, as individuals with different muscle fiber types may require different training regimens to maximize their performance and minimize the risk of injury.

💡Tactical advantage

A tactical advantage refers to the strategic use of one's strengths or the opponent's weaknesses to gain an edge in competition. In the video, it is mentioned that a tennis player with more slow-twitch muscle fibers might use tactics to wear down an opponent with faster fibers, leveraging their endurance to win.

💡Elite athletes

Elite athletes are individuals who compete at the highest level in their respective sports. The video discusses the importance of knowing one's muscle fiber type for elite athletes or those aspiring to reach that level, as it can help in predicting success in a particular sport and tailoring training to maximize performance.

💡Injury prevention

Injury prevention involves采取措施 to avoid physical harm during sports or physical training. The video highlights that understanding one's muscle fiber type can help in designing training programs that reduce the risk of injury, especially for those with fast-twitch fibers who may need more rest to prevent overtraining and subsequent injuries.

Ben jij ook graag in alles de beste?

play00:07

En doe jij liefst een sport waarvan je op voorhand weet dat je zal winnen?

play00:11

Of heb je al gedacht aan een topsportcarrière?

play00:14

In beide gevallen is het belangrijk om een sport te kiezen

play00:17

die je echt, maar echt, ligt.

play00:18

Hoe dat in elkaar zit, ontdekken we de komende minuten.

play00:23

Goed gedaan, goed gedaan.

play00:26

Wij van de Universiteit van Vlaanderen

play00:28

volgen bewegingswetenschapper Eline Lievens

play00:31

naar de sporthal van de Universiteit Gent.

play00:37

Onze spieren bestaan uit twee types spiervezel: snelle en trage.

play00:41

Sommige mensen hebben meer snelle spiervezels, andere meer trage.

play00:44

De verhouding van die vezels bepaalt voor welke sport je gemaakt bent.

play00:49

Ik gok dat die snelle spiervezels heel explosief zijn

play00:52

en de trage een langer uithoudingsvermogen hebben?

play00:55

Precies. De snelle spiervezels heb je nodig om krachtig samen te trekken,

play00:59

bijvoorbeeld om te sprinten.

play01:01

Denk aan Lukaku, een snelle voetballer.

play01:04

Die heeft wellicht veel snelle spiervezels.

play01:06

Die snelle spiervezels heb je ook nodig voor gewichtheffen,

play01:09

voor BMX en voor verspringen.

play01:11

En voor nog heel wat andere sporten ook.

play01:13

Maar die snelle spiervezels hebben ook een nadeel.

play01:17

Ze kunnen niet zo lang volhouden. Dan heb je de trage spiervezels nodig.

play01:21

Die trage spiervezels vind je daarom veel terug bij marathonlopers

play01:25

en bij triatleten.

play01:27

Het kan ook dat je evenveel snelle als trage spiervezels hebt.

play01:30

De meeste mensen zijn zo gebouwd.

play01:33

Dan ben je gemaakt voor een 800 meter in de atletiek,

play01:36

of tijdrijden in het wielrennen.

play01:38

Zo bepaalt het spiervezeltype dus

play01:41

of je eerder snel, traag of intermediair bent,

play01:44

en voor welke sport je gemaakt bent.

play01:47

De verhouding tussen die vezels is grotendeels genetisch bepaald.

play01:51

Je kan er niet veel aan veranderen door veel te trainen of zo.

play01:54

Die snelle en trage spiervezels zitten ook door elkaar in al je spieren.

play01:58

Ze zien er hetzelfde uit, maar werken helemaal anders.

play02:02

In de trage zitten meer mitochondriën,

play02:04

de energiefabriekjes van onze cellen.

play02:06

Daarom kunnen ze voor een veel langere tijd energie produceren,

play02:10

veel langer dan de snelle. Dat was al langer bekend.

play02:12

Maar dankzij Eline kan je redelijk makkelijk meten

play02:15

wat voor spiervezels je hebt.

play02:17

Tijdens mijn doctoraat optimaliseerde ik een methode om dat te meten.

play02:21

Er bestond al een methode, maar die methode is niet plezant.

play02:26

Dat is een understatement, want die doet heel veel pijn.

play02:29

Ik heb dat zelf ondergaan. Tijdens die methode wordt er

play02:32

met deze naald een stuk spier gesneden uit het been van de atleet.

play02:36

Dat doet niet alleen pijn, maar is ook niet helemaal representatief.

play02:41

Als je een tweede biopt zou nemen twee centimeter verder,

play02:46

zou dat mogelijk een ander resultaat geven.

play02:48

Veel meer snelle of veel meer trage spiervezels.

play02:51

Het is dus niet zo accuraat en doet pijn,

play02:54

en daarom ontwikkelden we een nieuwe methode.

play02:56

Ik ben benieuwd. Een nieuwe, pijnloze methode dus. Leg eens uit.

play03:00

Ik leg een atleet onder de scanner en meet daarbij de kuit.

play03:04

Die kuit vertelt het spiervezeltype van het volledige lichaam.

play03:08

Die kan dus ook een indicatie geven van het spiervezeltype

play03:12

in de biceps van de arm.

play03:14

Met die techniek meten we een honderd keer groter stuk

play03:17

dan we kunnen meten met een biopt.

play03:19

Het is veel accurater en je moet daarna geen wonde laten genezen.

play03:24

Met zo'n MRI-scan kan je dus meten welk spiertype je hebt.

play03:27

Moeten we dan vanaf nu alle schoolkinderen en voetballertjes

play03:31

door die scanner duwen?

play03:32

Het is niet de bedoeling dat elke 16-jarige onder de MRI-scanner komt

play03:36

om zijn spiervezeltype te laten bepalen.

play03:39

Als je wil kogelstoten of paardrijden, doe gerust en volg je hart.

play03:43

Het is inderdaad waar dat je met sprong- of sprinttesten

play03:47

een indicatie kan krijgen van je spiervezeltype.

play03:50

Ben je eerder snel of eerder traag?

play03:52

Maar het is belangrijk dat je rekening houdt

play03:55

met factoren die het resultaat van die sprongtesten kunnen beïnvloeden.

play03:59

Welke schoenen heb je aan?

play04:01

Heb je gisteren getraind en ben je nog moe?

play04:03

Heb je die sprint- en sprongtesten al veel gedaan?

play04:06

En ben je wel gemotiveerd?

play04:08

Voor wie is zo'n scan dan interessant? Voor topsporters of topsporters in spe.

play04:13

Als je de ambitie hebt om echt goed te worden in een sport,

play04:16

wil je je spiervezeltype meten.

play04:18

Dan weten we jouw sterktes en zwaktes

play04:21

en kunnen we zeggen op wie je spiervezeltype lijkt.

play04:24

Lijkt dat op Bashir Abdi of eerder op Lotte Kopecky?

play04:28

Dankzij de spiervezelmeting van Eline

play04:30

kan je als topsporter in spe al voorspellen

play04:33

of je kans maakt in een bepaalde sport

play04:35

of toch beter overschakelt naar een andere.

play04:38

Ik vroeg me nog af: moet je ook anders trainen?

play04:41

De meeste coaches gebruiken een one-fits-all-aanpak.

play04:45

Ze trainen dus al hun atleten op dezelfde manier.

play04:47

Maar dat is niet logisch.

play04:49

Personen met een snel spiervezeltype

play04:51

hoeven niet drie uur aan een stuk te trainen.

play04:53

En zeker niet meermaals op een dag, want ze hebben meer rust nodig

play04:57

en anders raken ze geblesseerd.

play04:59

Neem nu Vincent Kompany.

play05:00

Die had wellicht veel snelle spiervezels.

play05:03

We gaven hem te weinig rust.

play05:05

Hij moest trainen en volledige wedstrijden spelen.

play05:07

Daardoor heeft hij wellicht die vele blessures opgelopen.

play05:11

Als je weet welk spiervezeltype je hebt,

play05:13

kan je dat slim inzetten in wedstrijden.

play05:16

Zo scande ik eens een tennisster met veel trage spiervezels.

play05:20

Wanneer ze speelt tegen iemand met veel meer snelle spiervezels,

play05:23

kan je je voorstellen dat ze veel explosieve slagen moet incasseren.

play05:27

In het begin van de wedstrijd is dat zwaar.

play05:30

Maar dan komt het tactische.

play05:31

Als ze die persoon laat lopen en veel links en rechts speelt

play05:36

om die persoon uit te putten,

play05:37

kan ze de wedstijd misschien toch naar haar hand zetten

play05:41

en winnen op haar uithoudingsvermogen.

play05:45

Het zit erop. Merci om te luisteren.

play05:47

Ik hoop dat jullie het interessant vonden.

play05:50

Als dat zo is, zeker liken.
