Today: Fitness Principles The basic Principles of a Fitness
Program: Progressive Overload Consistency Specificity Diminishing Returns Reversibility Individuality Safety
Progressive Overload
For physical components to improve, the system must work harder than it is used to working!
Body is subjected to stress and overloads of varying intensities, it will gradually adapt, over time, to overcome these demands.
Key! Even though overload is important, the stress must not be great enough to produce injury/damage!
Therefore: use the FITT principle
FITT Principle
FITT principle for overload: Frequency—How often Intensity—How hard Time—How long (duration) Type—Mode of activity
Without overloading the system, progression does not occur!
Consistency
Big issue for college students = finding time!
Best time = when you have time and motivation
Creating a daily routine is important Least desirable times: after a meal,
before bedtime. # of days varies but you should try to
workout at least 3 times per week to see minimal improvements
Specificity
The body adapts to the particular type and amount of stress placed on it
To develop a particular fitness component, perform exercises specifically designed for that component
E.g. Running vs. Skiing
Diminishing Returns
Greatest gains: beginning of program
After initial increase: gains will continue at slower pace.
Benefits are only sustained if you maintain your exercise program.
Gains may be lost if you stop exercising!
Reversibility
Fitness improvements are lost when demands on the body are lowered
If you stop exercising, up to 50% of fitness improvements are lost within 2 months
Individuality
Everyone is NOT created equal from a physical standpoint
There are large individual differences in ability to improve fitness, body composition, and sports skills
A person’s exercise prescription needs to be based on individual goals, needs, functional capabilities, and interests.
Safety
“Train, don’t strain” Progress no more than 10 % increase
per week in training program (FITT) Warm-up? Yes or no?
Increase body temperature Stretch ligaments and muscles Increase flexibility Prepare for you workout! (specificity)
Guidelines for Training
Train the way you want your body to change
Train regularly Get in shape gradually; do not overtrain Warm up before exercise Cool down after exercise Exercise safely Add variety and have fun Try training with a partner Listen to your body!
