Study Notes

Physical Activity

Defined as all movements involving skeletal muscles that consume energy.
Increased physical activity leads to higher energy expenditure.
Exercise is structured physical activity aimed at improving fitness components: cardiorespiratory fitness, muscular endurance/strength, body composition, and flexibility.
Sport combines physical training with competitive goals, necessitating higher nutritional needs based on training duration, frequency, and intensity.

METs and FITT

MET (Metabolic Equivalent of Task) measures energy metabolism above resting levels:
- Low activity: score of 3-4 (e.g., household chores).
- Moderate activity: score of 6-8 (suitable for initial training).
- Vigorous activity: score of >10 (e.g., sprints, competitive sports).
FITT (Frequency, Intensity, Time, Type) guides exercise planning:
- Frequency: how often exercises are performed.
- Intensity: how hard exercises are performed.
- Time: duration of exercise sessions.
- Type: category of exercises being done.

FITT Concept

Cardiorespiratory fitness:
- Frequency: 3-5 times per week, beginners start at 3 times.
- Intensity: tailored to the individual; measures using maximum heart rate (MHR) and MET.
- Time: 20-60 minutes depending on intensity, with sessions lasting at least 10 minutes.
- Type: involves aerobic and endurance exercises.
Muscular Strength & Endurance:
- Frequency: beginners 2-3 days/week focusing on full body; advanced 4-5 days/week.
- Intensity: based on one maximum repetition (MR), beginners work at 50-70% MR.
- Time: duration varies from 1-3 sets of 8-20 reps depending on fitness levels.
- Type: includes weight machines, free weights, resistance bands, body weight exercises.
Body Composition and Flexibility:
- Body Composition: daily frequency, low intensity, includes walking and cycling.
- Flexibility: daily stretching, holding stretches for 10-15 seconds, using various stretching types.

Nutritional Scope

Sports nutrition links food management with physical performance, fostering health and fitness.
Improved nutrition quality enhances physical capability and operational efficiency in athletes.
Nutritional sciences combined with other disciplines support athletic performance.

Nutrition, Sports, & Health

Rising prevalence of degenerative diseases is associated with decreased adult physical activity.
Low physical activity correlates with health deficits and increased health risks.
Public health campaigns for physical activity often fall short of effectively meeting recommended guidelines.
Imbalance in calorie intake and physical activity can lead to increased body mass index and heightened risk of non-communicable diseases like diabetes and heart disease.
