Javelin Analysis Aerobic Power/cardio-vascular endurance.

Extracts from this document...


Javelin Analysis Aerobic Power/cardio-vascular endurance Javelin throwers need little or no aerobic power/cardio-vascular endurance because their event is purely anaerobic and lasts for such a short period of time that in needs only fast twitch fibres to achieve success. Anaerobic power/speed Javelin throwers undoubtedly need very good anaerobic power and speed because they take part in an event, which only takes a short period of time and requires a maximal effort. In terms of muscle fibres that they need to achieve the best results they require a very high percentage of fast twitch muscle fibres in comparison to slow twitch muscle fibres (around 60/70% fast twitch and 40/30% slow twitch). Of which of that 60/70% they want as many FTG (fast twitch glycolytic) muscle fibres as possible because their event is purely anaerobic so unlike FOG (fat oxidative glycolytic) muscle fibres which combine both of the two types, FOG's can work almost as well anaerobically as FTG muscle fibres but they lose some power and strength because they have a slightly small muscle diameter thus meaning they are not as strong. ...read more.


So to carry out these movements effectively and successfully they require good strength and power in these departments. Arm and shoulder strength and endurance Although javelin throwers require no endurance in terms of aerobic endurance but in order to be able to throw the javelin the javelin over very long distances and then possibly have to repeat this throw and try and better it in the next heat they do necessitate endurance in terms of FOG muscle fibres as these have the advantages of slow twitch fibres (good blood supply, myoglobin content) but also have the advantages of FTG muscle fibres (long fast firing motor neurones and ATPase for quire ATP production) so they do give a certain amount of endurance in terms of anaerobic work. Abdominal strength and endurance Javelin throwers need good strength and some endurance in their abdominals as they play a part in the in the throw because they must take there run up in almost a side on position too the direction they wish to throw the javelin and then rotate at the torso to give the throw extra momentum. ...read more.


Co-ordination Javelin throwers do require some co-ordination because they must be able to throw the javelin while thinking about how they need to move to counter balance them selves while under the stress and momentum of the throw. Although this seems simple in terms of co-ordination, without it would be almost impossible to balance while producing such a massive effort. Reaction Time Javelin throwers don't require fast reactions at all because their event doesn't involve any reaction to any kind of stimulus which needs a quick reaction. Timing Although javelin throwers don't need amazing timing they must be able to self pace themselves, especially in terms of timing of their run and timing of their throw, because there is a possibility of fouling by stepping over the throwing line javelin throwers must be able to time their throws. If they throw the javelin too early they will lose distance on their throw but if they throw too late they risking fouling. ...read more.
