Goals
• Specific Goals:• Facilitate recovery between training
sessions• Provide appropriate cardiovascular
response• Facilitate appropriate metabolic
response• Introduce / Initiate functional activity• Reduce incidence and severity of
injury• Enhance relaxation• Encourage fun

Overview and rationale
of
Aquatic Recovery
Injury Reduction
Prior to 2010 season
Avg. 4 ACL’s / season
Avg. 4-8 groin/adductor injuries
Avg. 6-8 inversion ankle sprains
Avg. 1-2 Achilles injuries
Avg. 3-5 Tibial stress reaction injuries
Avg. 4-8 misc. injuries
2010 -2011 Season
1 ACL tear2 LE stress injuries (no loss of play time)
Why the change
Screening / Testing
Constant monitoring
physiology
metabolism
psychological Profiling
Aquatic Recovery
Predictions don’t work!
VO2 assessment offers the advantage of objective measure
where incremental workloads can be adjusted / analyzed to
determine key markers on an individual basis…
NOT AN ESTIMATE OR AVERAGE!

Measured
Aerobic threshold, a critical variable in the determination of training / recovery levels.
Ranges from 50-90% of Hrmax
– 45-55% in untrained individuals– 60-68% in club exercisers– 75-80% in recreational anaerobic
athletes– 80-92% in highly trained aerobic

SV vs. HR in Aquatic Activityultimately it’s all about cardiac output (Q) on a consistent basis.
Decreased HR in aquatic environment
HR reduction due to SV
facilitated by hydrostatic pressure
2 fold benefit
Increased SV
Facilitated systemic “flush” via compressive forces of progressive immersion.
Aquatic HR formula
HRmax in H20 = HRmax on land - FC
Graef / Kruel , 2005
Factors affecting target HR in H20
Water temperature Dive reflex Reduced gravity Compression Partial pressure Reduced body mass

Aerobic BenefitsAquatic Recovery
Decreased lactateIncreased fat metabolism for fuelIncreased # and size of mitochondriaIncreased myoglobin levelsIncreased respiratory capacityIncreased aerobic generation of ATP
Aquatic Recovery Program
•Series of exercises done post- practice
or as supplemental (recovery) day.•Follows the progression principles of:
• FITT• Continuous HRM (55% or 10below AT)• HR variability in aquatic environment• Compression / Hydrostatic Pressure
• Pascal’s Law• Supportive environment – allows for
extra time to control movement – proprioception enhancement
• Turbulence functions to destabilize & as a tactile sensory stimulus
Program Composition
•Duration – 60min•Series of drills
• Progress according to• Graduated Progression
• ROM• Stability
• Single plane to multi-plane• Water flow via HydroWorx
• Concurrent data capture• CHM – various methods
