1.Types of Exercise Training & the Effects on the Body

2.Muscular Adaptations to Resistance Training
Increased size
Fiber type transition
Biochemical improvements (enzymes)
Increased strength, power, & endurance
3.Hypertrophy
Muscular enlargement
Cross sectional area, + relation w/strength
Result of increased synthesis of actin & myosin and number of myofibrils
4.Strength & Power
Strength - maximal force that a muscle or group of muscles can generate
Power - maximal force exerted as fast as possible - EXPLOSIVE!
5.Strength & Power
6.Endurance
Ability for the muscle to repetitively contract of a sustained period of time
Ultra-Marathoners
Rowing (long distance)
Distance runners

8.Interval Training
Increase & decrease intensity between aerobic & anaerobic
Work:active recovery ratio (1:3, 85-90%)
No more than 1 or 2 sessions/week to start w/ 3 days of rest
change 3:1 to 2.5:1.5 or 2.0:2.0
Go past aerobic threshold & then return to aerobic conditioning level to improve performance
intensity body switches from burning a greater % of fat to a greater % of carbs , 85% of your maxHR
Heart rate is great way to measure how hard you are working
Max heart rate=220-age
85% of max heart rate (21 years old): (220-age)x.85= 169.15
9.Advantages & Disadvantages
Advantages:
Fitness, performance, recovery time improve quickly
Improves aerobic fitness better than traditional training & in less time
Enzymes use oxygen more efficiently increased O2 capacity
Increase fat burn & can double endurance capacity w/ 15 min of intense cycling over a 2-week period
HR will be lower at work & active recovery
Disadvantages:
Performed too often can increase risk of overtraining
Symptoms: loss of performance & appetite, inability to sleep, chronic aches and pains & colds, overuse injuries, unusual fatigue, increase in resting HR, irritability
bad knees avoid intervals walking, running or jogging
Stop exercise if it hurts & modify workout
Check with doctor before starting interval training
10.Interval Training
Physiological effects:
@ low end of training range: working aerobically and burning more fat
@ high end of training range: HR increases, breathing harder, anaerobic, burning more carbs than fat
Reasons to do interval training:
improve recovery HR
weight-loss plateau
bored
Allows you to workout harder & longer & burn more fat & more calories
Must burn more calories than you consume to lose weight even with intervals
8-10min warm up & 5 min cool-down after intervals
See sample interval training
11.Interval vs. Circuit Training
Circuit training
Spend 30-45s at one machine or station with dumbbells or resistance exercise and then move onto next station
aerobic & RT
Another form of interval training
when you break from one machine to the next HR decreases & when you begin working out again it increases
wont be as beneficial as running or cycling intervals but will tone and strengthen muscles
Whereas aerobic interval training has more beneficial effects

13.High-Intensity Interval Training
Specialized form of IT
Short intervals of max intensity exercise-low to moderate intensity exercise
Similarities to traditional interval training
Differences include:
Increased EPOC
Burn more fat
Limits muscle loss
To get the benefits from HIIT
push yourself past the upper end of your aerobic zone & allow your body to replenish your anaerobic energy system during the recovery intervals
HII involve maximum effort, not simply a higher heart rate
there are many different approaches to HIIT
different numbers of high and low intensity intervals
different levels of intensity during the low intensity intervals
different lengths of time for each interval
different numbers of training sessions per week
14.Guidelines for HIIT
designed for people who want to boost overall cardiovascular fitness, endurance and fat loss without losing muscle mass
Before starting the program, you should be able to exercise for at least 20-30 minutes at 70-85% of maxHR
gradually build up your training program so that you don’t overdo it
warm up and cool down
Work as hard as you can during the high intensity intervals, until you feel the burning sensation in your muscles indicating that you have entered your anaerobic zone
If you experience any chest pain or breathing difficulties during your HIIT workout, cool down immediately
HR should be at 70% of maxHR during recovery
If it is not: shorten work intervals and/or lengthen recovery intervals

16.Cross-Fit
Combines weightlifting, sprinting and gymnastics
Proficiency is required in each of 10 fitness domains
cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination & accuracy
Fitness: increased work capacity across all domains
neurologic & hormonal adaptations across all metabolic pathways
Run, row, jump rope, climb rope, carry odd objects, move large loads over short distances & use power-lifting & Olympic weightlifting
Used by 2000 gyms, F.D., law enforcement agencies, military organizations
At a gym: warm up, skill development segment, high intensity workout for 10-20 min
Can be used by: children, pregnant women, seniors, football players, military special forces, endurance athletes
Performed 3-5 d/week can provide exercise that will satisfy exercise guidelines
Has greater health benefits than moderate activity
17.Cross-Fit
"equals better fitness and stronger muscles in a more reasonable amount of time“
"build muscle and get in shape by spending 60 minutes or more in the gym several days a week..."
"is a different type of exercise routine ...a well-rounded and very efficient way to achieve a higher level of fitness ...that does not need a whole lot of fancy equipment, but does offer a nice variety to keep the interest level up and provide the challenge needed to keep the exercise fun.”
