Fatigue protocol
| Study group | Role | What they receive |
|---|---|---|
| IPC | Experimental | Intermittent pneumatic compression treatment (30 min peristaltic protocol, at 200mmHg) Receives: Other: recovery |
| Placebo | Placebo comparator | A hydrant cream will be used as a placebo Receives: Other: recovery |
What is being measured
The primary outcome is the main question the study is designed to answer.
Muscle soreness
Muscle soreness will be assessed using the likert scale of muscle soreness (ranging from 0 to 6)
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
Creatine Kinase
Creatine kinase will be assessed
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
Secondary outcomes (7)
Low frequency fatigue - Myocece Powerdex score
Low frequency fatigue will be assessed using Myocene
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
4 min time trial
A 4 minute time trial will be conducted at the 24th hour post-intervention.
Measured: 24 hours post intervention
Isometric knee extension srength
Isometric Knee extension exercise will be assessed
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
Percieved fatigue
Likert scale of percieved fatigue (ranging from 0 to 10)
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
Sleep questionnaires (consensus sleep diary)
Sleep quality and quantity will be assessed using a questionnaire, based on the consensus sleep diary
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
Perceived recovery
Total quality recovery scale will be used
Measured: Baseline, post 30 minutes, post 24 hours, and post 48 hours
Nutritional diaries
Participants will be asked about their nutritional intake during the timecourse of the assessments
Measured: Baseline, post 24 hours, and post 48 hours
