3. Objectives:
Exercise and its benefits
Exercise related MACE and SCD
Terminologies in Exercise
Case scenarios
Exercise recommendation on the basis of Age groups
Exercise recommendations on the basis of different pathological
conditions
7. EXERCISE-RELATED MACE
1. CV events during intense exercise occur at a rate of around
1 event per 100 years of vigorous activity.
2. Risks are highest during the first few weeks of beginning
vigorous exercise; therefore both exercise intensity and
duration should be increased gently (for example, every 4
weeks).
3. Among older individuals who are well prepared and
accustomed to intense exercise, participation in competitive
vigorous sports does not confer higher risk compared with
younger adults.
8. MACE
1. SCA and SCD.
SCA is defined as an unexpected collapse due to a cardiac cause in which CPR
and/or defibrillation is provided in an individual regardless of the survival
outcome.
SCD is defined as a sudden unexpected death due to a cardiac cause, or a sudden
death in a structurally normal heart at autopsy with no other explanation for
death and a history consistent with cardiac-related death (i.e. requiring cardiac
resuscitation)
2. Exercise-induced ACS.
3. TIA and CVA.
4. SVT.
9. SCD in athletes
Variable (1/1,000,000-1/5000)
Higher in males (3:1-9:1).
Higher in black athletes.
Higher in basketball (US) and soccer (Europe) athletes.
Young athletes: Genetic, Congenital.
Athletes>35y: Atherosclerotic CAD (>80%)
esp. vigorous, with little/no
background in systematic training.

11. DEFINITIONS
Physical Activity is defined as any bodily
movement produced by the skeletal muscle that
results in energy expenditure.
Exercise or exercise training is PA that is
structured, repetitive, and purposeful to
improve or maintain one or more components
of physical fitness.
12. DEFINITIONS
Athlete: young or adult (amateur or professional)
who is engaged in regular training and participates
in official sports competition.
Elite athletes (national
teams/Olympians/Professional): exercise≥ 10
h/wk.
Competitive athletes (High school/college/master
club level): exercise≥6h/wk.
Recreational athletes (for pleasure/leisure time):
exercise≥4h/wk.
13. EXERCISE INTENSITY
Exercise intensity is generally considered
to be the most critical for achieving aerobic
fitness and to have the most favorable
impact on risk factors.
Absolute intensity refers to the rate of
energy expenditure during exercise usually
expressed in kcal/min or metabolic
equivalents (METS).
Relative exercise intensity refers to a
fraction of an individual's maximal power
(load) that is maintained during exercise.
usually prescribed as a percentage of
maximal aerobic capacity (VO2max) on
the basis of a CPET.
14. Case Scenario
A 25-year-old male with no significant past medical
history presented to his primary care clinician for a pre-
employment physical examination. He has been active
and has no complaints. His family history was
unavailable, as he was adopted. On physical
examination, his blood pressure was 110/60 mm Hg with
a heart rate of 60 bpm, and his examination was within
normal limits. An electrocardiogram (ECG) was
obtained (Figure 1).

16. Which of the following activities would
you recommend as possibly safe?
A. Hockey.
B. Soccer.
C. Swimming.
D. Diving.
E. Golf.
17. Correct answer is E Athletes with a definite diagnosis of
arrhythmogenic right ventricular cardiomyopathy (ARVC) should not
participate in most competitive sports, with the possible exception of
low-intensity class 1 sports (ACC & ESC)
