tissues

Central vs. Peripheral
Aerobic vs. Anaerobic Adaptations
CENTRAL FACTORS (O2 Delivery)
Oxygen Loading: Rate & Depth of Breathing (lungs), Hemoglobin (blood)
Oxygen Delivery: Heart Rate & Stroke Volume (heart), Ejection Fraction, Cardiac Output
(Q = HR x SV)
PERIPHERAL FACTORS (O2 Extraction)
Oxygen Extraction (arterio-venous O2 diff.): Muscular Capillarization & Myoglobin
Oxygen Utilization: Mitochondrial Density, Oxidative Enzymes, % Slow Twitch,
Conversion of Fast Twitch Glycolytic (IIb) to Fast Twitch Oxidative (IIa)
Absolute VO2 MAX = Q x O2 Extraction (a-v O2 diff.) = (HR x SV) x O2 Extraction
Relative VO2 MAX = (HR x SV) x O2 Extraction / bodyweight
Absolute VO2 MAX = Q x O2 Extraction (a-v O2 diff.) = (HR x SV) x O2 Extraction
Relative VO2 MAX = (HR x SV) x O2 Extraction / bodyweight
1. Your client weighs 70kg, has a resting HR of 60bpm,
stroke volume is 70ml/beat, and O2 extraction is 6ml
O2/100ml of blood. What is their resting VO2?
2. During maximal exercise the same client has a heart
rate of 180bpm, a stroke volume of 115 ml/beat and an
O2 extraction of 15ml O2/100ml of blood. What is their
VO2 max?
3. Another client has a max HR of 177bpm and a cardiac
output of 16, 992 ml/min. What is this client’s stroke
volume?
1 MET = 3.5ml O2/kg/min
1. Your client has a maximal HR of 178bpm, a stroke
volume of 103 ml/beat, an O2 extraction of 14ml
O2/100ml of blood and weighs 64kg. What is their
relative VO2 max? What is the VO2 equivalent in METS?
Describe an activity that would fulfill this value.
2. What is the VO2 equivalent to 4 METS? Describe an
activity that would fulfill this value.
3.MET’s are often used in a medical environment
o
By convention 1 MET is considered as the resting metabolic rate
obtained during quiet sitting
1. Target Heart Rate
2. Talk Test
3. RPE (Rating of Perceived Exertion, Borg Scale)
PARTNER EXERCISE: Calculate the Target Heart
Rate for your Case Study Client.
a) Calculate THR using standard MHR Formula
THR = (220 – age) x Exercise Intensity %
b) Calculate THR using the Karvonen Formula
HRR = [(220 – age) – RHR] x Exercise Intensity % + RHR

Improve or maintain the level of efficiency to
deliver O2 and remove CO2; aerobic and/or
anaerobic training
At least 3x/week with 24-48hrs rest between
sessions
Dependent upon energy system to be trained for
client’s goals
Dependent upon intensity level prescribed; lower
intensity conducted over longer time period (i.e. 30min +)
can be accumulated intermittently or continuously
Continuous vs. Discontinuous Training (i.e. Intervals);
Both Aerobic & Anaerobic Systems must be trained
PARTNER EXERCISE: Using your partner’s
data determine 1) your client’s S.M.A.R.T. Goals,
and 2) apply the O.F.I.T.T. principle to design
their CV program. Be prepared to share with the
rest of the class.
1. What is the minimum FREQUENCY, INTENSITY and DURATION/TIME
required to maintain aerobic fitness (the central factors)?
2. What is the minimum FREQUENCY, INTENSITY, DURATION/TIME and
EFFORT INTERVALS required to maintain anaerobic fitness (the
peripheral factors)?

Objective: Enhance muscle’s ATP-CP energy capacity
 5-10 second max output bursts followed by 30-120sec
active recovery; Alternate between 2+ work intervals and
2+ recovery intervals
 Adaptation occurs within 2-4 weeks. Detraining will take
effect within 2 weeks.
 Note: high risk training; potential injuries associated with this
type of training.
 Especially important to warm up and cool down.
 Benefits = sprinters/events lasting less than 20 sec.
Objective: Elevate Lactate Threshold Levels
 Sub max levels of intensity will not stimulate
adaptation. Need to train at level that will elicit lactic
acid production.
 Train 2-3x/week (ample time for recovery); 2-3 min
effort intervals followed by 2-3 min recovery
intervals; repeat 2-12x
 2-3 min recovery is not enough time to deplete lactic
acid from blood, therefore lactate threshold must
elevate to accommodate the training stimulus.
 Note: complete LT training at least 2 weeks before competition
 Benefits: Everyone, but the highest injury rate.
Objective: Improve body’s ability to deliver O2 and remove
CO2 through central factors
 Sub-maximal training; 60-80% MHR, 20min +
 Not necessarily “sport specific”
 Most benefits are central adaptations involving the heart
circulatory and respiratory systems.
 Note: the most appropriate introductory cardiovascular
program to start with to build a good fitness base.
ATP-CP INTERVAL TRAINING: 5-10 second max output bursts (95100% HRR; RPE = 9-10) followed by 30-120sec active recovery;
Alternate between 2+ work intervals and 2+ recovery intervals
GLYCOLYTIC INTERVAL TRAINING: 2-3 min effort intervals (85-95%
HRR; RPE = 7-8) followed by 2-3 min recovery intervals; repeat 2-12x
Indicate the training objective for each sample program:
Example 1: 30sec (max intensity) / 30sec (active rest), repeat
4-12x
Example 2: 90sec (90% HRR) / 90sec (recovery), repeat 10x
Example 3: 60sec (85% HRR) / 120sec (70% HRR), repeat 7x
Indicated by a plateau or drop in performance over a period of several
days; caused by too little recovery time between sessions
