Brief Summary:
The key research objective is to examine the effects of a high protein spoonable yoghurt on overnight recovery of muscle function, 12 hours following an exercise session in 18-45-year-old males and females, compared to a control group receiving flavoured waterbased placebo jelly. An additional aim of the study is to explore the effects of the test product vs placebo on muscle function, readiness to exercise and performance in a repeat bout of exercise training at 24 hours following initial exercise training.
Detailed Description:
This study is a single-blind, randomised, parallel group design. It involves six visits to the laboratory in total; Visit 1) pre-screening and consent; visit 2) questionnaires, anthropometrics, and familiarisation; Visit 3) baseline measures; Visit 4) exercise intervention (exercise session 1); Visit 5) post-exercise morning measures, and Visit 6) exercise intervention (exercise session 2). Participants will be randomised into one of two groups that will receive the following;
1. Test product: High protein spoonable yoghurt (1 serving = 45 g protein comprising 3 yoghurt pots totalling 480 g) (Danone Nutricia).
2. Control product 2: flavoured water-based placebo jelly (1 serving = 0 g protein comprising 3 jelly pots totalling 480 g).
A follow-up communication via telephone will be conducted within 7 days of completion of the final session to ensure there are no adverse effects of participation.
A detailed overview of the research activity that will take place in each session is provided below:
Visit 1: Pre-screening Volunteers will receive information on the study, and they will be familiarised with the requirements for participation and provide written informed consent. Subjects will be requested to complete 3-day food and exercise diaries, comprising of 1 weekend day, 1 rest day, and 1 exercise day within a week of the trial. This will be handed in on Visit 2. Subjects' body height, body mass, body composition, and BMI will be measured.
Visit 2: Familiarisation with the dependent measures and exercise training Volunteers will refrain from physical activity and alcohol consumption 24 hours before each visit and caffeine 12 hours before each visit. Study staff will review physical activity and food diary questionnaires and if eligibility criteria are met, volunteers will continue the trial. Measure of volunteers' body mass, stature and body composition will then be recorded. Next, volunteers will be familiarised with the dependent measures and exercise training session that will be conducted.
Visit 3: Baseline Measures Volunteers will report to the laboratory in the PM in a fed (2-3 hours post prandial) and hydrated state, where baseline measurements of all dependent variables will be taken. Which will include muscle soreness via a visual analogue scale, muscle pain pressure threshold via algometry. Measures of muscle function including Counter Movement Jump (CMJ), Reactive Strength Index (RSI) and Isometric Maximal Voluntary Contraction (iMVC). A venous blood sample will be taken to measure creatine kinase and high sensitivity C-reactive protein.
Following this, volunteers will receive standardised meals for the day of the exercise trial. Standardised meals will provide:
* Total energy (kcals) = BMR (derived via Harris-Benedict) x 1.5 (PAL). Assuming participants will be largely sedentary apart from the exercise session.
* Protein 1g/kg body weight for both groups.
* Carbohydrate - Provide 50% of total energy
* Fat - Remainder of total energy.
Participants will keep their habitual physical activity pattern between visits but not exceeding 4 exercise sessions per week (pro-rata), of which not more than 2 sessions of light resistance exercise sessions can be completed. Any exercise outside of the study will be recorded. Volunteers will be asked to refrain from any strenuous exercise 24 h prior to the first visit and for the duration of the subsequent trial visits (except for that required during the study). Volunteers will record any deviations from the standardised meal plan in a food compliance diary throughout.
Visit 4: First exercise training session Volunteers should consume breakfast before \~8 AM, lunch \~12 PM, and dinner at \~4 PM. Volunteers will attend the study site in the evening, scheduled at least 2 hours after dinner. Study staff will receive completed food compliance diary from volunteers. Volunteers will be asked to complete all dependent measures. This will be followed by the exercise training consisting of an initial warm up, a repeated sprint cycling challenge followed by an exercise circuit that will consist of intermittent high intensity exercises (detailed below) for a period likely to extend approximately 40 minutes. The session will be similar to a high intensity exercise class and the number of repetitions will be recorded in each time window to compare between Visit 4 and 6. Volunteers will wear a heart rate monitor throughout to measure peak and mean heart rate. Immediately after, measures of the participant's lactate concentration and their perceived exertion for the session followed by a further lactate sample at 15 mins. Volunteers will then complete all dependent variables and consume the test product or control product.
The exercise protocol is detailed below and will be repeated in visit 6. Warm up
* Static exercise bike 5 minutes at 1.5 W per Kg Body mass
* Standardised dynamic warm up (\~5 minutes of walking lunges, squats \& mobility) Cycle Ergometer Repeated Sprint
* 10 x 6s Lode Bike sprints with 30 s (active) recovery Circuit Training 5 rounds with a 30s 1:1 work rest ratio.
* Kettlebell Thrusters (bilateral)
* Squat Jumps (set height from plyometric box)
* Kettlebell Walking Lunge (bilateral) • Kettlebell Swing (single)
* Kettlebell bent-over row
* Sled push 40 m
* Sled pull 40 m
* Farmers walks (bilateral kettlebell) Total time \~60 minutes Notes
* Kettlebell weight to be selected at familiarisation and used throughout (likely \~10-20% BM)
* Sled Row/pull will be a % of BW (TBC - likely 50% BM)
Visit 5: 12-hour overnight recovery following exercise training session 1 The participant will have a standardised breakfast at home \~7 AM and attend the laboratory \~ 2 h after. Participants will attend the study site at \~9 AM. Study staff will receive completed food compliance and study product intake diaries following exercise training 1 session (visit 4). Participants will be asked to complete a Recovery Questionnaire and the Sleep Quality Questionnaire. Participants will complete muscle soreness and pain measures. Study staff will measure volunteers' body mass and draw a blood sample. Next, volunteers will complete all dependent variables. Volunteers will consume a final serving of the study or placebo product in the laboratory when all measures are completed. After the visit volunteers will consume the provided lunch and dinner at home, at \~12PM and \~4PM, respectively.
Visit 6: 24-hour return to training readiness and performance following exercise training session 1 Physiological and performance measures pre- and post-exercise training session 2). Participants will attend the laboratory at least 2 hours after dinner (\~18:00). Study staff will receive completed food compliance diary from volunteers between visit 4 and visit 6. Volunteers will be asked to complete the Recovery, Readiness to Exercise, and muscle soreness questionnaires. Study staff will measure volunteers' body mass and draw a blood sample. Then, volunteers will complete all dependent variables. After 10-15 minutes rest, volunteers will complete a second exercise training session, which will be identical to visit 4), wearing a heart rate monitor. Immediately after exercise training session 2, blood lactate concentration will be measured, followed by a further sample at 15 minutes and rate their perceived exertion. Lastly, after these measures volunteers will repeat dependent measures of muscle soreness/pain and muscle function.
1. Test product: High protein spoonable yoghurt (1 serving = 45 g protein comprising 3 yoghurt pots totalling 480 g) (Danone Nutricia).
2. Control product 2: flavoured water-based placebo jelly (1 serving = 0 g protein comprising 3 jelly pots totalling 480 g).
