KempFitness was invited to take part in a research study.
Study title: A physiological profile of recovery from resistance, endurance and mixed exercise types.
What is the purpose of the study?
Research investigating the usefulness of a variety of recovery strategies applied in both short-term and long-term settings has shown mixed results. It has been suggested that the type of exercise is a key factor in determining whether a recovery strategy will be beneficial or detrimental for short-term recovery or long-term training adaptation. Therefore the aim of this study is to provide a physiological profile of recovery from different types of exercise. The information gained will help in the understanding of how recovery from different exercise types may differ. Based upon these findings, it may be possible to match certain recovery strategies to post-exercise recovery goals, enabling a more informed selection of recovery strategies to enhance both short-term recovery and long-term training adaptation. The study will be divided into a control and an exercise week, whereby you will be required to visit the state of the art GSK Human Performance Lab on five consecutive days twice to conduct a variety of assessments.
Visit 1 = Familiarisation session 1
Visit 2 = Familiarisation session 2
Visit 3 = Baseline assessments + Control session + 2h & 6h post-control assessments
Visit 4 = 24h post-control assessments
Visit 5 = 48h post-control assessments
Visit 6 = 72h post-control assessments
Visit 7 = 96h post-control assessments
Visit 8 = Baseline assessments + Exercise session + 2h & 6h post-exercise assessments
Visit 9 = 24h post-exercise assessments
Visit 10 = 48h post-exercise assessments
Visit 11 = 72h post-exercise assessments
Visit 12 = 96h post-exercise assessments
Who has reviewed the study?
The study has received full ethical clearance from the Research ethics committee who reviewed the study. The committee is the Middlesex University, School of Science and Technology, London Sport Institute Ethics sub-committee. Additionally, the study has been internally reviewed by the GlaxoSmithKline Medical Governance Review Board.
What will happen to the results of the research study?
The results of the research study will be used as part of a Postgraduate dissertation. The results may also be presented at conferences, in journal articles, or through GSK Human Performance Lab Expert communications (www.gskhpl.com). However, the data will only be used by members of the research team and at no point will your personal information or data be revealed. Following publication of the results, on request, we will be able to provide a summary of the study results, although we will only be able to provide group data.
All information you provide will be treated in accordance with the UK Data Protection Act.
lactate profile into VO2max assessment. For this assessment I will be required to cycle at 150-200 W for 4 minutes, with power increased by 25 W every 4 minutes. A small blood sample will be taken from the end of your finger as well as you giving a rating of your perceived exertion at 3 minutes during each 4 minute stage. Respiratory and heart rate data will be collected throughout by collecting your expired air through a face mask and using a heart rate monitor. The test will be terminated when the investigator is satisfied that your blood lactate concentration has coincided with identification of the second lactate turn point
I got up to 370 W with blood lactate turn point at 275 W
The VO2max assessment. The test will start at a power output of 200-250 W and will be subsequently increased by 4 W every 10 seconds (24 W per minute) until you cannot continue to cycle at the required power output.
I managed 10 minutes and got up to 400 W. On 17.2.16
Perform an all-out five minute cycling time-trial sounds (easy right.... )
Warm-up 5 minute warm-up at 100W, with a 10 second sprint at 2 minutes 30 seconds. You will then complete a 5 minute all-out time trial, covering as much distance as possible in 5 minutes. You will be blinded to the time during the test as well as distance covered except being informed of the half-way stage by the investigator
Blood sample. This will be taken by a trained phlebotomist using standardised procedures. Samples will then be processed and stored at -80 degrees at the GSK Human Performance Lab until further analysis. Subsequent analysis will take place at the GSK Human Performance Lab and samples will be analysed for markers of inflammation, muscle cell disruption, oxidative stress, muscle damage, collagen remodelling, and cell repair. Additionally, two samples will be sent to the University of Ulster to be analysed for markers of oxidative stress.
Perceived recovery by completing a questionnaire; indicate your perceived muscle soreness on a visual scale. and jump as high as possible, using your own choice of depth and pace, whilst maintaining your hands on hips, on a force platform three times with one minutes rest between each effort to assess your rate of force development and countermovement jump performance.
Fully bend and straighten your leg three times to assess your range of motion.
Maximally kick your leg three times against a fixed lever arm with one minutes rest between each effort to assess the muscle strength of your leg muscles.
You will be instructed to maintain your normal diet during the control week (other than abstaining from alcohol and caffeine) and will be provided with a diet diary to record this, before being asked to replicate this diet during the exercise week that follows.
Battery of baseline assessments, which in addition to the previous assessments that you were familiarised with will include having your upper leg measured for limb girth
I was administered with an actigraphy wrist-watch which will be used to record various parameters of sleep and activity and will be worn continuously from visits 3-7 and 8-12.
