Physiological Effects of Exercise on
Cardiac Output
 Increased sympathetic stimulation
 Contraction of muscles around vessels
 Dilation of resistant vessels in muscles

Physiological Effects of Exercise on
Muscle Blood Flow
 Flow at rest versus during exercise
 Mechanisms for increased blood flow

Physiological Effects of Exercise on
Oxygen Demand
 Oxygen uptake by pulmonary blood

Physiological Effects of Exercise on
Metabolic Rate
 Muscle 100 x more heat than at rest
 In well trained athlete body heat can
• ↑50 x for a few seconds
• ↑ 20 x for few minutes
 Metabolic rate ↑ 2000 x
 Basal metabolic rate (70 kg):
•
•
•
•
Bed = 1650 calories
Eating = 1850 calories
Sitting = 2000 calories
Exercise = (170-100 calories/hour)

Physiological Effects of Exercise on
Hydration
 Exercise ↑ body temperature as results of three
factors: metabolic rate, environmental conditions, body
temperature
 Net water = [liquid/food consumed + metabolism] –
[respiratoryloss + GIloss + renalloss + sweatloss]
 Hypohydration versus euhydration versus
hyperhydration

Sports Nutrition
(ADA Position Paper “Nutrition and Athletic
Performance”)
 Carbohydrate recommendations
 Protein recommendations
 Fat recommendations
 Dehydration
 Goals (pre-exercise, during exercise,
post-exercise)

Sports Injuries
 By location
• Lower extremities at greatest risk
• Upper extremities – greatest risk not age but specific
skill demands
• Central body

Stages of Sports Injury Rehabilitation

6 weeks
 Stage 3 – remodeling phase lasting 3 weeks to 12
months

Exercise Guidelines
 Physical activity guidelines (2008)
• Avoid inactivity
• Some better than none
• Any activity provides some benefit
 Metabolic equivalent units (MET)
 Cardiometabolic exercise (CME) - General health and
gradual weight loss = 150 points/day or ~1000
points/week

Aerobic Exercise versus Resistance
Exercise
AET
RET
Improves CV reserve
Increased muscle/bone mass/strength
Increased skeletal muscle adaptation
Improved psychological well being
Decrease age-related accumulate of
central body fat
Decreased cognitive decline
Trained older individuals sustain
maximum exercise load with less CV
stress and muscle fatigue
Improved glycemic control and clearance
of post-prandial lipids

 The ant-idiabetic, antihypertensive and LDL
cholesterol-lower medication use may be reduced by
walking, function of
• Walking distance
• Longest walk
• Walking intensity
