Understanding Physiological Adaptations to Exercise: A Comprehensive Guide, Quizzes of Physical Education and Motor Learning

An in-depth exploration of the various physiological adaptations that occur in response to different types of exercise training. Topics covered include the importance of training each system, the role of the overload principle and specificity, individual differences, and changes to the aerobic and anaerobic systems, body composition, and cardiovascular and pulmonary functions. Additionally, the document discusses the psychological benefits of regular physical activity.

What you will learn

  • What is the overload principle and how does it enhance physiologic function?
  • What are the differences in adaptations between the anaerobic and aerobic systems during exercise training?
  • What are the physiological adaptations that occur in the body during aerobic training?

Enhancement in muscle fiber capacity to

aerobically

generate ATP TERM 7

Increase in mitochondrial

DEFINITION 7 size and number TERM 8

Two-fold increase in level

DEFINITION 8 of aerobic system enzymes TERM 9

Enhancement in both fiber types

DEFINITION 9 existing aerobic capacity and lactate threshold level TERM 10

Adaptations to Exercise Training: Anaerobic

System Changes

DEFINITION 10 Increased levels of anaerobic substrates I ncreased quantity and activity of key enzymes that control anaerobic phase of glucose catabolism Increased capacity to generate high levels of blood lactate during all-out PA

Pulmonary Adaptations

Improvements in VO2max with training increase VEmax Improvement to sustain high levels of submax VE: Enhanced ventilatory economy contributes to overall endurance performance in two ways: Reduces fatiguing effects of PA on ventilatory musculature Frees O2 from respiratory muscles by nonrespiratory active muscle Reduction in ventilatory equivalent for oxygen in submax activity TERM 17

Body Composition Changes

DEFINITION 17 For overfat or borderline overfat people, regular aerobic PA reduces body mass and body fat. Increases in FFM accompany a regular program of resistance training. Exercise only, or exercise combined with calorie restriction, reduces body fat more than fat lost with dieting only. TERM 18

Temperature Regulation

DEFINITION 18 Well-hydrated, aerobically trained individuals move more comfortably in hot environments because of larger plasma volume and more responsive thermoregulatory mechanisms. Trained men and women dissipate heat faster and more effectively than untrained persons. For trained individuals, metabolic heat generated by PA poses less of a detriment to performance and overall safety. TERM 19

Enhanced endurance accompanies

physiologic training adaptations

DEFINITION 19 true TERM 20

Psychological

Benefits

DEFINITION 20 Regular PA, either aerobic or resistance training, produces psychological benefits independent of age.

Factors Affecting the Aerobic Training

Response

Initial Level of Cardiorespiratory Fitness: Improvement occurs if initial fitness is low; high level of initial fitness leaves little room for improvement. Training Frequency: Training response occurs with PA performed at least 3 weekly for at least 6 wk. Training Duration :Moderate-paced PA for 30 min each session is a realistic duration recommendation for the average person. Training Intensity: 50% to 55% VO2max or 70% HRmax = minimal threshold stimulus for cardiovascular improvement. TERM 22

Two important factors in formulating aerobic

training regimens:

DEFINITION 22 Cardiovascular demands must reach an intensity to sufficiently increase or overload SV and Q. Cardiovascular overload must activate sport-specific muscle groups to enhance local circulation and muscle metabolic machinery. TERM 23

Optimal Training

Intensity

DEFINITION 23 Seven ways to express intensity: Energy expended per unit time Absolute power output Relative metabolic level (expressed as %VO2max (e.g., 85% VO2max) Activity below, at, above LT or OBLA Activity HR or %HRmax (80% HRmax) Multiples of RMR (e.g., 6 METs) Rating of perceived exertion (e.g., RPE = 14) TERM 24

HR at 70% HRmax represents moderate PA

DEFINITION 24 can continue for long durations with little physiologic discomfort TERM 25

Trainability and Genes Genotype dependency

DEFINITION 25 occurs for sensitivity in responding to max aerobic and anaerobic power training, including muscle enzyme adaptations. Limits for developing fitness capacity link closely to natural endowment: For two individuals in the same program, one might show 10 more improvement than the other

Training-Karvonen Method

  1. Determine Predicted Maximal HR = 220 BPM-Age2. Determine Resting HR3. Determine Maximal Heart Rate Reserve (MaxHRR) = Maximal HR-Resting HR4. Select % of MaxHHR (i.e. 60-90%)5. Add % MaxHHR and Resting HR = Threshold of Training TERM 32

relative intensity) for

DEFINITION 33 which establishes a subjects initial training intensity. TERM 34

Anaerobic Training:

DEFINITION 34 All-out exercise for up to 60 sec. TERM 35

Continuous

Training

DEFINITION 35 Continuous (long slow distance) training that requires sustained, steady-rate aerobic activity.

Interval

Training

Specific spacing of high-intensity activity and rest periods:HIIT training: 1-min bouts at 90% HRmax followed by 1-min easy recovery:10 total activity and recovery intervals for total workout time = 20 min TERM 37

Fartlek

DEFINITION 37 Performer determines training schema based on how it feels at the time. This type of training alternates, i.e. running speeds and terrain TERM 38

Overtraining Syndrome

DEFINITION 38 Two clinical forms of overtraining: Sympathetic form Characterized by increased sympathetic activity during rest and generally characterized by hyperexcitability, restlessness, impaired performance2. Parasympathetic formCharacterized by predominance of vagal activity during rest and PA TERM 39

Symptoms of Overtraining and

Staleness
