coaching points VO2 max
Player is working aerobically in-between plays when the ball has gone out of play or when the ball is at the opposite side of the pitch waiting for the ball to shift to their side of the pitch. For example, the player I observed was on the right wing and they will be working aerobically whilst they are waiting for the ball to shift to their side of the pitch when they are not involved. They will be taking in high levels of oxygen in-between contractions to aid recovery.
Theory for VO2 max
Factors affecting VO2 max include gender, training, physiological factors and age. The performer I observed was quite young so this will increase their VO2 max and looking at the standard of the game I observed they clearly train frequently so this will again increase their VO2 max. Physiological factors are an adaptation due to training so they will have an increased alveoli, increased red blood cell count as well as cardiac hypertrophy will occur which will further increase their VO2 max as from your early 20s your VO2 max declines by 1% each year so frequent training can counteract this.
Overall effect on performance VO2 max
This had an overall effect on performance as VO2 max was a strength for this performer as they was able to recover in-between attacking runs really well. There was an attacking run that lasted for longer than 20 seconds early on in the clip and my performer was constantly moving and receiving the ball, helping in set plays this was anaerobic. There was then minimal time to recover as their team lost possession and they had to drop back and recover to help defend as the opposition counterattacked down their wing and a high VO2 max is needed to resynthesise ATP and PC, replenish myoglobin and remove any lactic acid that was produced. I believe this was a strength as they was still able to press with the same intensity as they did when they made their attacking run.
Explosive strength coaching points
Explosive strength is the maximum force applied against a resistance in a series of rapid contraction. Player is using explosive strength when shielding the ball from defenders as they are applying a maximum force against the defender to prevent them from being outmuscled and losing possession.
Explosive strength theory
Explosive strength or power comes from a muscle contraction which is controlled by a motor unit, a motor unit is defined as a motor neurone and its muscle fibres. A neurotransmitter like acetylcholine must be released to exceed a threshold to generate an action potential, this causes the muscle fibres to contract in an all or non fashion, where rather all the muscle fibres contract or all relax.
Explosive strength overall effect on performance
This had an overall effect on performance as this was a weakness for this performer as they wouldnt be able to apply a large force rapidly and would easily get outmuscled when shielding the ball and therefore would struggle to keep possession as they would panic. This occured a few times throughout the clip. If the performer had good explosive strength they wouldve been confidently able to hold up the ball shielding it from the defenders holding their arm out keeping their body between the defender and the ball with their head up looking for the right time to pass without becoming unbalanced or being outmuscled.
Reaction Time coaching points
Reaction time is the time taken to respond to a stimulus. Reaction time is essential in football, having good reaction time means that when the keeper is kicking out from a goal kick for example they can react and move quickly to the ball intercepting the pass or even moving and scanning where future passes could be made getting ready to block/intercept them, helping them to read the play of the game.
Overall effect on performance reaction time
Overall effect
on performance was that reaction time was a strength for this performer as they moved and intercepted the ball on multiple occasions from both passes and goal kicks. They was able to read body positioning of players, anticipating their next move, preventing the opposition from moving further up the pitch on numerous occasions as well as intercepted the ball in the final third after the defender made an inaccurate pass which allowed the performer to react quickly and intercept which gave the performer a chance to attack towards the goal.
Reaction time theory
Social loafing/dehydration
Speed coaching points
Speed is the ability to cover a distance or perform a movement in a given time. Speed is frequently used in football especially in attacking 1v1 situations, as the faster you attack towards the defender the harder it is for them to defend. Speed is also essential for when possession has been lost and you need to react quickly and track back to help defend slowing down their counterattack, helping to win the ball.
Overall effect on performance speed
This had an overall effect on performance as this was a strength for the performer, as they was able to beat defenders in fights for lose balls, which allowed them to regain possession for their team and then allowed them to make set plays. This was also evident as they would frequently manage to drive past the defender with ease down the wing which enabled them to put a through ball to their attackers on multiple occasions, allowing them to maintain control of the game. Furthermore, it was also clear that speed was a strength for this performer as they was able to help get back and defend after losing possession and the opposition was counterattacking, helping to press fast with high intensity putting pressure on the oppositions attackers.
Speed theory
This will act as a performance accomplishment for the performer and will increase their self efficacy in future games as they will believe they have the capability to use speed well again. Other factors affecting self efficacy include verbal persuasion, emotional arousal and vicarious experiences.
Balance coaching points
Balance is the ability to maintain centre of mass over bass of support. Balance is essential in football especially when heading the ball, as when landing back down from a header the player bends their knees, lowering their centre of mass towards the ground creating more stability for the performer so they are not off-balance when they land, and therefore can move off with ease.
Overall effect on performance balance
This had an overall effect on performance as balance was a weakness for this performer, this was evident as when landing backdown from the header the performer didn’t pay attention to their knee placement , which caused them to have incorrect feet placement causing their knees to bend incorrectly, therefore when bending their knees, although they did lower their centre of mass they didnt manage to create stability due to the incorrect feet placement, so when trying to move after landing form a header they was offbalanced and further couldnt react quickly to
Balance theory
Performer can increase their balance by reducing their stability, this can be done by raising their centre of mass such as moving their arms away from their body, minimising the amount of contact points with their base of support.
