Assessment Assignment 2.1

Date set

Submission Date

Overview

Scenario

You are on work placement at a local gym. Your supervisor has asked you to put together a personal training plan for a client. However, before you do this she would like you to carry out a series of investigations to ensure that you fully understand the different body systems involved, how they work together during exercise and why they should be taken into account during fitness training and sports participation.

 

Activity 1

Understanding the initial responses of the body to exercise is important in a range of professions, for example, cardiologists, fitness consultants and personal trainers. To be able to work effectively in the sport and exercise industry you need to have a good understanding of how the body reacts to exercise. This will enable you to plan the intensity level of exercise or training for the people that you work with.

 

Your supervisor has asked you to investigate the initial responses of the cardiovascular and respiratory systems to exercise. In the investigation you will first need to record the resting heart rate, breathing rate and blood pressure of your participants, using the table below. These three readings should also be monitored during the exercises you have devised. The results taken during exercise can then be compared to the initial resting levels you have recorded and a report written explaining what the results mean.

 

The body’s responses to acute exercise are as follows.

 

  • Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement; muscle fi bre micro tears.

 

  • Energy systems: phosphocreatine; lactic acid; aerobic; energy continuum; energy requirements of different sport and exercise activities.

 

  • Cardiovascular response: heart rate anticipatory response; activity response; increased blood pressure; vasoconstriction; vasodilation.

 

  • Respiratory response: increase in breathing rate (neural and chemical control); increased tidal volume.

 

After you have collated the data using the table below Describe the cardiovascular and respiratory systems responses to acute exercise (P2).

Activity 3

 

Explain the response of the musculoskeletal, cardiovascular and respiratory systems to acute exercise (M1).

 

 

 

 

Hint

 

P1

 

For P1, learners need to describe the responses of the musculoskeletal and energy systems to a single bout of exercise. They will need to include how muscle responds to exercise including the increased blood supply and also the effects of resistance exercises which includes micro tears. Each of the energy systems should be described and their contribution to exercise as the exercise bout continues over a period of around 30 minutes.

 

P2

 

For P2, learners need to describe how the cardiovascular and respiratory systems respond to a single bout of exercise. This should also include the pre-exercise effects which occur in the heart. Learners should explore the effects over an exercise period of around 30 minutes so that steady state has been attained.

 

M1

 

For M1, learners need to explain the responses of the musculoskeletal, cardiovascular and respiratory systems to a single bout of exercise. They will need to include how muscle responds to exercise including the increased blood supply and also the effects of resistance exercises which includes micro tears. Cardiovascular and respiratory responses should be explained; learners should give reasons and provide the physiological evidence to clearly support their explanation.

 

Grading Criteria

 

This assignment will assess P1, P2 and M1.

 

P1

Assessment Assignment 2.3

 

Date set

Submission Date

Overview

Scenario

 

Understanding the responses of the body to exercise is important in a range of professions, for example, fitness consultants and personal trainers. To be able to work effectively in the sport and exercise industry you need to have a good understanding of how the body reacts and recovers.

You should also be able to measure and test clients to determine any problems that they may have.

This will enable you to plan appropriate exercise levels and rest periods for the people that you work with.

 

Activity 1

 

While shadowing the personal trainer at the gym, you have been asked to assist in practical testing and assessment of individuals in a variety of exercises. Once testing is complete you will need to present the results in a PowerPoint presentation to the personal trainer explaining the scores that you have analysed.

 

You will need to investigate the effects of exercise in a range of activities that could be used in a training programme.

 

Collect physiological data to investigate the effects of exercise on the musculoskeletal, cardiovascular, respiratory and energy systems, with tutor (P5) limited tutor (M3) independently (D1) support

 

This should include exercises for the musculoskeletal system, cardiovascular system and energy systems. Use the table below to record the results of your investigation.

The exercises can include:

 

  • aerobic exercises, e.g. treadmill running, cycling, rowing

 

  • anaerobic exercises, e.g. ski squat, vertical jumps or 1(rm) lifts, or cycling (such as spinning).

 

Repeated Wingate tests can help replicate accurate scores for spinning hill climb or sprint sections.

You must select at least two exercises – one from each of the aerobic and anaerobic lists.

For the aerobic exercises, pre-exercise levels need to be recorded for resting heart rate, blood pressure and tidal volume. Anaerobic scores could also include a record of flexibility or strength scores.

Data should then be collected during an activity. The activity should last for 30 minutes for aerobic and up to 30 seconds for anaerobic. The performer could also be monitored in recovery.

 

 

 

 

Factor Exercise one Exercise two
Resting Heart Rate
Exercise heart rate
Per cent heart rate
Rating of perceived exertion
Blood pressure
Breathing rate
Flexibility (if applicable)

 

 

 

 

 

Activity 2

 

Your supervisor would now like you to review physiological data collected, describing (P6) explaining (M4) and analysing (D1) the effects of exercise on the musculoskeletal, cardiovascular, respiratory and energy systems.

 

 

 

 

 

 

Hint

 

P5

 

For P5, learners will have received tutor support whilst setting up and collecting physiological data from an investigation. Learners should select at least two different types of exercise in order to determine how the different types of exercise result in differing adaptations. Learners should also examine the acute response to their selected exercises as well as the long-term effects of exercise. Physiological data should be recorded pre-, during and post-exercise.

 

P6

 

For P6, learners need to examine the data collected and review the results by describing how the body responds to each type of exercise during the acute phases and also the long-term effects of the selected exercises. Learners need to review physiological data collected before, during and post-exercise. Consideration should also be given to the practicality of the exercise activities selected, and any advantages or disadvantages encountered during data collection. Learners should be able to describe the strengths and areas for improvement of their investigation.

 

M3

 

For M3, learners will have received very little tutor support whilst setting up the investigation and collecting physiological data from the investigation. Learners should select at least two different types of exercise in order to determine how the different types of exercise result in differing adaptations. Learners should also examine the acute response to their selected exercises and also the longer term effects of exercise.

 

M4

 

For M4, learners need to examine the data collected and review the results by explaining how the body responds to each type of exercise during the acute phases and also the long-term effects of the selected exercises on the body systems. Learners will also need to explain the practicality of the exercise activities selected, and any advantages or disadvantages encountered during data collection. Learners should be able to explain the strengths and areas for improvement of their investigation.

 

D1

 

For D1, which links to P5 and M3, learners will have independently conducted their investigation. Learners should select at least two different types of exercise in order to determine how the different types of exercise result in differing adaptations. Learners should examine both the acute response to their selected exercises and also the longer term effects of exercise.

 

D2

 

For D2, which links to P6 and M4, learners need to examine the data collected and review the results by analysing how the body responds to each type of exercise during the acute phases and also the longer term effects of the selected exercises. The analysis will need to include the practicality of the exercise activities selected and advantages/disadvantages encountered with the way in which physiological data was collected. An analysis of the strengths and areas for improvement of the investigation will need to be included in the review.
