Aim and purpose
The aim of this unit is to provide a broad understanding of the importance of nutrition and hydration to a variety of sports participants.
Unit introduction
The importance of good nutrition and hydration in sports has grown in popularity in recent years. The significance of a healthy balanced diet and its links to good health and improved sports performance is now a key aspect of the sportsperson’s lifestyle; whether they are an elite athlete preparing for World championships or Olympic events, a semi-professional competitor aiming to continue performing or amateur participants …show more content…
who just want to improve their chances of winning.
The demands of rigorous training and competition schedules can have negative effects on the health of every sports participant, but the individual’s diet, linked to the recovery process, can have a considerable effect on performance. Involving the sports performer in the planning of their diet can result in improved health benefits, as well as promoting adequate refuelling and hydration, leading to improved sporting performance. Any adjustment to the nutrition plan can also be linked to energy requirements and expenditure for a variety of different sports and events. The importance of this information should also be extended to other members of the sports team such as coaches, personal trainers and strength and conditioning personnel.
This unit is particularly relevant to those who aspire to work in coaching, fitness instruction, sports nutrition or elite sport.
The first part of the unit focuses on the concepts of nutrition and digestion, with learners exploring the physiology of the digestive system and how food is broken down and subsequently utilised by the body.
Learners will then be introduced to the components of a balanced diet and common terms linked to nutritional requirements.
Learners will also explore energy intake and expenditure and how this can be measured in different ways for individual sports performers. Learners will also consider the availability, costs and accuracy of these measures and how relevant they are to the performer. Learners will identify the influencing factors directly linked to energy input and output, including gender, age, climate and physical activity.
The second part of the unit looks at hydration and diet for different sporting activities. Learners will investigate the sporting demands of performers and how nutritional requirements will vary for each individual. The inclusion of sports drinks, gels and traditional methods of hydration will be considered, alongside the activity levels and fitness levels of the individual. Finally, learners will be able to apply knowledge and understanding by producing a realistic diet and hydration plan for selected athletes or sports performers.

Essential guidance for tutors
Delivery
Tutors have the opportunity to use a wide range of techniques, including lectures, seminars, presentations, practical workshops, practical laboratory sessions, external trips, and guest speakers. Additional
learning resources can include journals, nutritional software packages, videos, DVDs, case studies, learner presentations and group work.
Learners need to understand the complexity of dietary influences, not only in relation to different exercise conditions but also how the different nutritional needs and energy requirements of the sports performer can affect performance.
Tutors should emphasise that learners will not be qualified sports nutritionists after completing this unit, and should not give any sports performer dietary advice or make recommendations for supplements. However, learners will have some scope to evaluate dietary plans for sporting activities and recognise where they could be improved in general terms. In addition, they will be able to recognise and identify nutritional terminology.
This unit could include researching the diets of peers, designing a food plan pyramid, keeping a food diary log, and establishing how the diet may be better balanced, meeting nutritional, hydration and energy requirements.
The emphasis in this unit is on encouraging learners to utilise the theoretical aspects of energy requirements, meal planning and hydration and then to contextualise these points for a named sports performer. This will include considering factors such as age, gender, training schedules, competition requirements and specific body measurements, in order to devise a realistic plan. It may be appropriate that this dietary plan is delivered at a certain time and linked to a specific individual. Alternatively, it could be delivered in the format of a selection of case studies, from which only one is selected by each learner. This delivery could include devising dietary plans and information leaflets to give to performers on replenishing fluids and food; presentation in a logbook format could be considered.

Assessment
Assessment strategies should focus on linking theoretical understanding to practical application.
For P1, learners must be able to describe nutrition and nutritional requirements using common terminology associated with nutrition and guidelines available from recommended public health sources. Learners must be familiar with the guidelines available from recommended public health sources. For P2, learners must be able to describe the structure and function of the digestive system and be familiar with the enzymes that break down specific food sources. There should be a clear link to the process of absorption and excretion of digested foodstuffs.
Criteria P3 and P4 focus on the energy balance required from different body measurements and sporting activities. Although not all the practical resources may be available, external visits to Universities or local health clubs could be incorporated as part of the assignment where more specialised equipment is required.
Alternatively, simple methods of measuring energy output could be utilised such as the use of pedometers, skinfold calipers, protocol charts or pre-published questionnaires, the results of which can be linked to learners’ laboratory reports.
For P5, the emphasis is placed on knowing the relevance of hydration and how it may impact on sports performance. Assessment could be in the form of a poster linked to sports performance. The digestion of fluids could be linked back to P2 (the digestive process), and also to P3 and P4 in relation to energy balance and performance within the principles of training. For P6, learners need to describe the components of a healthy balanced diet. For P7, learners need to produce an appropriate two-week diet plan for a selected sports performer for a specific sports activity. This should also include relevant hydration. Examples could be provided by a selection of pre-determined case studies at given timescales of the training programme, or a sports performer or athlete known to the learner. Learners must be able to focus on the description of a balanced diet, giving specific examples of food sources of both macro and micronutrients whilst utilising information from food labels.
For M1 and M2, learners should provide an explanation of energy intake and expenditure and explain the importance of energy balance in relation to sports performance. Grading criterion M3 links to P6, and to meet this learners should explain the components of a healthy balanced diet.
The status of the performer (amateur, semi-professional, professional or elite) should have significant bearing on the dietary plan, and this needs to be carefully considered, in particular for M4, which requires an explanation of the plan.
Criterion D1 builds on P4 and M2 and requires learners to analyse the effects and importance of energy balance for sports performance. In their analysis, learners will need to identify the factors which contribute to energy balance and assess their effects on sports performance. Practical examples should be provided where appropriate to support the analysis.
Grading criterion D2 builds on P7 and M4, and learners need to justify the two-week diet plan they have prepared. This means learners will need to provide reasons and/or evidence to support why they designed the plan in the way they did. The two-week dietary plan can be presented in any format, as an ongoing logbook or a portfolio of evidence.

Assessment
Assessment strategies should focus on linking theoretical understanding to practical application.
For P1, learners must be able to describe nutrition and nutritional requirements using common terminology associated with nutrition and guidelines available from recommended public health sources. Learners must be familiar with the guidelines available from recommended public health sources. For P2, learners must be able to describe the structure and function of the digestive system and be familiar with the enzymes that break down specific food sources. There should be a clear link to the process of absorption and excretion of digested foodstuffs.
Criteria P3 and P4 focus on the energy balance required from different body measurements and sporting activities. Although not all the practical resources may be available, external visits to Universities or local health clubs could be incorporated as part of the assignment where more specialised equipment is required.
Alternatively, simple methods of measuring energy output could be utilised such as the use of pedometers, skinfold calipers, protocol charts or pre-published questionnaires, the results of which can be linked to learners’ laboratory reports.
For P5, the emphasis is placed on knowing the relevance of hydration and how it may impact on sports performance. Assessment could be in the form of a poster linked to sports performance. The digestion of fluids could be linked back to P2 (the digestive process), and also to P3 and P4 in relation to energy balance and performance within the principles of training. For P6, learners need to describe the components of a healthy balanced diet. For P7, learners need to produce an appropriate two-week diet plan for a selected sports performer for a specific sports activity. This should also include relevant hydration. Examples could be provided by a selection of pre-determined case studies at given timescales of the training programme, or a sports performer or athlete known to the learner. Learners must be able to focus on the description of a balanced diet, giving specific examples of food sources of both macro and micronutrients whilst utilising information from food labels.
For M1 and M2, learners should provide an explanation of energy intake and expenditure and explain the importance of energy balance in relation to sports performance. Grading criterion M3 links to P6, and to meet this learners should explain the components of a healthy balanced diet.
The status of the performer (amateur, semi-professional, professional or elite) should have significant bearing on the dietary plan, and this needs to be carefully considered, in particular for M4, which requires an explanation of the plan.
Criterion D1 builds on P4 and M2 and requires learners to analyse the effects and importance of energy balance for sports performance. In their analysis, learners will need to identify the factors which contribute to energy balance and assess their effects on sports performance. Practical examples should be provided where appropriate to support the analysis.
Grading criterion D2 builds on P7 and M4, and learners need to justify the two-week diet plan they have prepared. This means learners will need to provide reasons and/or evidence to support why they designed the plan in the way they did. The two-week dietary plan can be presented in any format, as an ongoing logbook or a portfolio of evidence.
