Executive Summary:

The human body is a masterpiece machine and can perform way beyond our expectations if it is trained for efficiency. At the same time, it wears and tears at a fast pace. Sportspersons are trained to give high energy performance and play a sport without messing up the functioning of their bodies. Football, being a popular game all very the world, including the United Kingdom, is a well known sport. It is a sport where players require high levels of energy and fitness to be able to perform well. The physiological demands for football players are quite high and multiple factors impact the performance of the players. This report is a literature review and literature analysis on the factors that researchers have described as important to understand the physiological demands for football players. Based on an analysis of several academic articles, an attempt has been made to recommend strategies that can he used by football players to improve their performance in this sport. 



Football is a sport where in a player requires high levels of energy to be able to perform well. The physiological demands are to be analyzed in order to understand the factors that affect the performance of a football player. New techniques in exercise and physical training enable sports persons to avoid injuries and ensure that their fitness levels are maintained at the best possible level. This makes it very important for sportspersons and their coaches to understand the level of nutrition and exercise that each of them require. Only then it would be possible to design an appropriate training program for footballers. Research on various academic sources indicates that there is a need to include higher level of protein in the diet of footballers along with ensuring better usage of cyclical fitness regime  (Perusse et al, 2012).

2 - Physiological Factors Affecting Performance

  1. Energy Requirement during Matches

              This indicates that high energy levels are required for a football player to be able to perform well. As the physiological demand of a football player is high, it becomes important that they be trained to be able to meet the required energy levels. The energy requirement levels of footballers are extremely high. It is important that they are well nourished and well supported with nutrients during the matches. High levels of fitness is extremely important for them to have stable performance. Only then they would be able to ensure high energy during the matches (Louise M Burke , Bente Kiens & John L Ivy, 2012). It is important for football players to ensure high levels of fitness throughout a game and not just or a part of it. This makes it important for them to learn energy management. Only then they would be able to perform well. 

  1. Physical Strength

                        The physical strength of footballers needs to be high. As they require continuous running during the match, endurance and physical strength have been marked as the most important factors that can help footballers ensure better strength (Perusse et al 2012). It is important that there be long term building of physical strength for football players. This can help them grow in their performance and do well in the long run. Physical strength helps them not tire out during a match and this forms an important aspect of being able to perform throughout the match. 

  1. Running Speed

             Running speed is very important in football. It is important for players to ensure that they get sufficient carbohydrates and proteins in their diets along with practice and training for running. High speed running can result in injuries if a player is not trained for it. It is important that there be a clear understanding of how running speed and technique can be improved. This can be made possible only through building of effective levels of training and nutrition. It helps build a stronger physique for the sportspersons and can help them perform better. The running speed of the players is a very important element in case of football. It plays a strong role in helping players perform. It is important for football players to be able to run and be able to defend the ball. 

  1. Agility

             Agility is a very important aspect of building physique and ensuring the physiological growth of the sportsperson. Investigators have consistently documented improved endurance performance in athletes using carbohydrate beverages, compared with water or other placebo beverages and this has been known to help agility among sportspersons to a great extent. It is important for sportspersons to be able to understand as to what aspects can help their body grow and improve performance. These aspects are to be considered while focusing on performance of sportspersons. 

  1. Endurance

             Endurance is extremely essential for sportspersons to be able to perform based on their physique. It is important that there are better levels of endurance built while creating a stronger health level for each of the players. As they run in a high speed and their heart beat rate increases significantly it becomes important that there is better consumption of carbohydrates and protein in the diet of the football players. Only then it would help them build higher endurance. At the same time it is important that there is long term improvement of endurance in order to help create better performance of the players in the sport. It is important to build a better level of endurance in football players to help them perform better (Luca Mondazzi & Enrico Arcelli, 2009). 

3- Critical Analysis of Physiological Demands

Genetic analysis and Nutritional analysis

            Every living being has a different capacity and ability that can predict their strengths and weaknesses, which are an important factor in performance. It is possible that increased availability of total calories may have contributed to the performance improvements observed in the trials performed (Bangsbo, J, 2000). Normally, competitors have exhibited expanded execution time to weariness, or expanded power yield amid the later phases of delayed exercise. It is for the most part trusted that these execution benefits are determined in light of the fact that starch drinks increase blood glucose levels amid the later phases of delayed exercise, when muscle glycogen levels are essentially lessened. It is very important for players to be able to achieve better nutrition levels as well to be able to play and manage their energy levels during a game.

Starches (CHO) can be characterized based on their glycemic list (GI), and the utilization of this order has been progressively bolstered by science. In view of its effect on blood glucose and insulin reactions following the ingestion of CHO nourishments, the GI has been considered in numerous fields of medication, including don sustenance. As another apparatus in wear nourishment, glycemic record control has been assessed to enhance the to start with and second periods of glycogen recuperation, glycogen load, and exercise digestion, including control of bounce back hypoglycemia and, it is fascinating to note, incitement of lipid oxidation for longer accessibility of glucose sources amid perseverance work out (Jonathan D. Bartlett, et al, 2017). It is important for a player in football to focus on delivering higher levels of performance and this makes it important that there is better nutrition and genetic balance achieved by each player.

Albeit alluring, the utilization of GI in brandish sustenance has gotten just incomplete help from accessible exploratory confirmation (Anthony Barnett, 2006). At the biochemical level, steady confirmation has been achieved propose that GI control can decide varieties in adipocyte lipolysis, plasma free unsaturated fats levels, and lipid and CHO oxidation rates amid work out. In any case, when the impacts of GI control have been surveyed at the practical level, the outcomes have been conflicting, with confirmation of enhanced exercise execution in a few examines, however not in numerous others. The motivation behind the present article is to survey the impacts and cut off points of GI control in don nourishment, and to propose a general system for its application.


 Proficient group activity competitors encounter an extensive variety of every day and week by week requests, for example, preparing, rivalry, media, also, group gatherings. Of these requests, preparing is a fundamental and critical action to amplify athletic execution. In any case, it is fundamental that preparation be recommended suitably to abstain from overtraining as well as damage. Together, striking a harmony between these requests and guaranteeing that competitors perform taking care of business has moved toward becoming a noteworthy test for mentors and games experts (A. Barnett, 2006). 

At the point when dietary admission amid exercise and recuperation was limited to water just, the main period of recuperation after requesting exercise sessions that drained muscle glycogen to 25% of resting level was portrayed by a high glycogensynthesis rate, with maximal action amid the initial 30 minutes and after that a quick decay to around one fifth by a hour and to around one ninth by 120 minutes after the finish of activity. This high glycogen-union rate is supported by 2 components: It is important for players that they are able to manage their energy levels well before the game and are also able to understand how this can benefit them. It is important for players to be able to understand the geonomical balance that they can build based on their ability to exercise and train for the game as well as their matches. 

  1. Expanded glucose      take-up and expanded glycogen 
  2. Synthase movement

 Amid this short-enduring period of recuperation the muscle take-up of glucose can continue freely of the nearness of insulin and is more dynamic when muscle glycogen toward the finish of activity is low. Despite the fact that the physiological foundations support the decision of high GI CHO amid the principal period of recuperation after glycogen draining activity, exploratory prove is rare and underpins this idea just when the recuperation time is short. In spite of the fact that there has been enthusiasm for recognizing the preparation stack factors that influence s-RPE preparing load, just 1 think about has endeavoured to reveal which non training qualities may influence s-RPE. It is very important for each player to be able to strike a balance between their ability and potential in order to play well. It is also important for them to be able to grow in terms of running speed, agility and endurance which would not be possible without effective training, better understanding of game requirements and management of energy throughout the game. It is important that players are well nourished and well rested before the game so that they are able to perform better and also manage themselves well during the whole game (Luca Mondazzi & Enrico Arcelli, 2009). 

5. Need analysis

The need for a footballer to have the right nutrition and exercise training is well understood through research. The articles researched indicate that on an average, footballers go through about 5 to 6 hours of training every day, six days a week. Moreover, they follow special diets which are high in protein and can help them perform better. It is quite important that the need of each of the player be assessed in order to help them improve individual performance. It is required for them to be able to understand the nuances of their own physiology and then perform, diet and work out accordingly (Louise M Burke , Bente Kiens & John L Ivy, 2004).

It is important that there be focus on the health implications of all of these activities including the impact of long term diets and delivery of performance as it can result in wear and tear of the body. It is important to evaluate the focus on the improving of the game as well as the health of the player. Only then a training approach can be considered suitable for the players even in the long run (Louise M Burke , Bente Kiens & John L Ivy, 2004). An analysis of the needs of the players indicates that there has to be better understanding of how each of the nutrients affects their performance. Only then it would be possible to ensure that they are getting the right diet and right nutrition in order to maintain the required energy levels during the game. 

6. Techniques and approaches for monitoring exercise training

                     Incremental exercise has been considered as an important strategy in creating long term development of footballers. Cyclic repetitions of exercises and focused training have helped them improve their performance to a great extent. It is important that the work out sessions be based on suitability to an individual and only then it can be considered as the right technique. If not, it would result in several injuries and problems to the players (Jonathan D. Bartlett et al, 2017). The training techniques used should be well monitored and understood in the context of age, body composition and strength of the player. Only then it would be possible to bring in an improved approach towards the game (Pe´russe, L T. Et al, 2013).

7. Recommended Strategies

The strength training of a soccer player focuses not just on building the muscle mass of the body but also on keeping a toned body that is useful for running, sprinting and agility (Louise M Burke , Bente Kiens & John L Ivy, 2004). Agility improvement, Endurance improvement, Power building and Running exercises processes can help build a stronger level of physiological endurance for players (Michael J. Saunders, Mark D Kane, and M. Keant Todd, 2015). 

All things considered, observing the outside load (EL) and the inward load (IL), amid both preparing and rivalry, is perceived as key in illuminating the administration of competitors. To be sure, a developing assortment of writing appears that administration of preparing load is compelling in diminishing the hazard to injury,1– 3 and also enhancing athletic performance.. When requesting exercise sessions tail each other at short time interims, it is valuable to renew glycogen stores between sessions. The principal period of recuperation could have a noteworthy part in this procedure (Jonathan D. Et al, 2017). These aspects indicate that there has to be better levels of growth among various elements including nutrition and exercises to help football players perform better. Only then it would help them grow in terms of performance and energy levels. It is essential for players to build a balance between their potential capacity and achieved energy as well as endurance (Micahel J et al., 2015). 

8. Conclusion

To conclude, since the initiation of glucose take-up and glycogen synthase by muscle compressions is fleeting, the high glycogen-blend rate of the main period of recuperation ought to be upheld by nourishing procedures went for getting the speediest rate of glucose conveyance to muscles. Along these lines, it ought to be desirable over pick high GI CHO, which can ensure a quicker and more prominent increment in blood glucose levels thought about with low GI CHO (Luca Mondazzi & Enrico Arcelli, 2009). 


On this premise, it ought to be sensible to conjecture that there is no distinction amongst high and low GI CHO organization amid the initial 2 hours after the finish of a glycogen exhausting activity, gave that there is adequate time to recoup and the adequate CHO is ingested amid the entire recuperation period. Interestingly, when the recuperation time frame is short and under 8 hours is accessible between 2 work out sessions, the decision of high GI CHO could really make muscle glycogen achieve higher focuses by the beginning of the following episode of activity (Louise M Burke, Bente Kiens & John L Ivy, 2004).  These elements indicate that glycogen forms a very important aspect of building better growth in performance of the players (Anthony Barnett, 2006). It is important for football players to be well trained and be able to perform well on the ground for which they require to be well nourished and have a good physiological metabolism. Only then they would be able to perform well. It is important that there is complete understanding of their body for them as well as their coaches or trainers, which can help them, perform well throughout the game and yet maintain a good health without any injuries or problems.
