Monitoring Recovery: HR analysis in Sub maximal workloads and how - PowerPoint PPT Presentation

Monitoring Recovery: HR analysis in Sub maximal workloads and how to implement it into your training environment Rob Rupf Sport Physiologist Canadian Sport Centre Ontario

Recovery • Is a critical process for programming in high volume sports • Monitoring recovery and having the ability to detect minute changes that can impact performance is critical to the ongoing development of the athlete.

Recovery • Things that need to be done – Nutrition – Sleep – Hydration • But how do we monitor recovery – Questionnaires – Heart Rate

Heart Rate • Heart rate and recovery – WHY? – Autonomic Nervous System • Role in exercise • Role in whole body control • Influenced by various stress hormones – Therefore can get an idea of stress placed on the body by measuring HR

Resting HR • Resting HR’s – Is a good place to start analyzing ANS. • Increased vagal tone or decreased sympathetic tone means lowered HR. • Increased sympathetic tone or decreased vagal tone means increased HR.

Resting HR and Training Performance

Potential Limitations of Resting HR • Other peripheral causes and cardiac adaptations can lead to increases in HR after initial adaptations • While this is great for short term ventures (ie training camps), longer term solutions may provide misleading information • Exercise may provide greater opportunities to provide longer term adaptations and determine health of recovery – Submaximal exercise may provide a better indication

Sub Maximal HR Monitoring Systems • Idea of using this monitoring system – Understand how that athlete will train during that session – Understand the metabolic costs of training – Ability to help predict their performance?? • This will give us more immediate feedback on each individual athlete. – Athlete specific – And it will help us know how the athlete is feeling right at that moment

Protocol • 2 X 200m on 4 minutes – One at an easy pace (50 beats below max HR) – One at a moderate pace (30 beats below max HR) • Incorporate this into the warm up • Plot the results

Right Shift – Good Response

Left Shift – Poor Response

Scenario 1 – Right Shift

Performance Increase

High Metabolic Cost?

Training Load Implications • Training Load hits the target zone • Increased cardiac load but similar lactate values shows greater efficiency in stroke mechanics???

Scenario 2 – Left Shift

They still can hold performance

Breakdown in Technique?? Disproportionate Increase in SR

Physiological Cost Disproportionate Increase in La and HR

Training Load Implications • Training times can be maintained. It will just hurt more. • Maintaining these times might produce higher than desired physiological loads. – This may be primarily due to breakdown in stroke technique

Sub Maximal Monitoring and Performance ??

Overview • Using HR can help determine changes in performance – Both resting and submaximal • Longer term chronic use of resting HR may be limited • Use of Submaximal testing may provide more sport specific information on loading – How much internal load that athlete will undergo? – Breakdown in stroke efficiency? – Prediction on future performance??
