Exercise science combines biology, physiology, and anatomy to understand how physical activity affects the human body.
Key Exercise Science Terms
Basic Fitness Concepts
- Aerobic Exercise: Activities that use oxygen for energy production, like running or cycling
- Anaerobic Exercise: Short-burst activities that don’t rely primarily on oxygen, such as weightlifting
- DOMS: Delayed Onset Muscle Soreness, the pain felt 24-72 hours after intense exercise
Training Terms
- Sets: Groups of repetitions in strength training
- Reps: Individual movements within a set
- 1RM: One Rep Maximum – the maximum weight you can lift for one repetition
Body Composition Terms
| Term | Definition |
|---|---|
| BMI | Body Mass Index – weight in kg divided by height in meters squared |
| Lean Mass | Body weight minus fat mass |
Exercise Physiology Terms
- VO2 Max: Maximum oxygen consumption during exercise
- Heart Rate Zones: Different intensity levels based on percentage of maximum heart rate
- Metabolism: Chemical processes that convert food into energy

Common Training Principles
- Progressive Overload: Gradually increasing workout intensity
- Specificity: Training specifically for your goals
- Recovery: Time between workouts for muscle repair and growth
Quick Tips for Exercise Success
- Track your progress using a workout journal or fitness app
- Start with proper form before increasing weights
- Stay hydrated before, during, and after exercise
- Get adequate sleep for optimal recovery

FAQs
- What is the difference between aerobic and anaerobic exercise?
Aerobic exercise requires oxygen for energy production and includes activities like running and cycling, performed for longer durations at moderate intensity. Anaerobic exercise doesn’t rely on oxygen and includes short, intense activities like sprinting and heavy weight lifting. - How many calories should I consume daily to maintain a healthy weight?
The average daily caloric needs vary by individual, but generally range from 2,000-2,600 calories for men and 1,600-2,000 calories for women, depending on age, height, weight, and activity level. - What is BMR (Basal Metabolic Rate) and why is it important?
BMR is the number of calories your body burns at rest to maintain basic life functions. It’s important because it represents 60-75% of daily caloric expenditure and is crucial for determining energy needs and weight management goals. - What’s the optimal protein intake for muscle building?
Research suggests consuming 1.6-2.2 grams of protein per kilogram of body weight daily for muscle growth. This should be spread across multiple meals throughout the day for optimal absorption. - How long should I rest between strength training sessions?
Major muscle groups typically need 48-72 hours of recovery between strength training sessions. However, this can vary based on training intensity, experience level, and overall fitness goals. - What is DOMS and how can it be managed?
Delayed Onset Muscle Soreness (DOMS) is muscle pain that typically occurs 24-48 hours after exercise. It can be managed through light activity, proper hydration, adequate sleep, and gentle stretching. - How does macronutrient balance affect exercise performance?
Macronutrients (carbohydrates, proteins, and fats) each play vital roles in exercise. Carbohydrates provide primary energy, proteins support muscle repair and growth, and fats assist in hormone production and long-duration activities. - What is VO2 max and why is it significant?
VO2 max is the maximum rate of oxygen consumption during intense exercise. It’s a key indicator of cardiorespiratory fitness and endurance capacity, measured in milliliters of oxygen per kilogram of body weight per minute. - How does proper hydration impact exercise performance?
Proper hydration maintains blood volume, regulates body temperature, and transports nutrients. Even mild dehydration can decrease performance by 2-3%. The general recommendation is drinking 17-20 oz of water 2-3 hours before exercise. - What role does rest and recovery play in fitness progress?
Rest and recovery are essential for muscle repair, strength gains, and preventing overtraining. This includes adequate sleep (7-9 hours), proper nutrition, and scheduled rest days between intense workouts.
