dietary guidelines in college
question
skipping the first meal, increased evening eating, overweight and obesity, consuming majority of calories in one meal or immediately before bed (body doesn't like to digest while trying to sleep- doesn't like to multitask) causes: higher body fat levels, harder to stay awake in class, poorer quality of sleep, more frequent colds, and limits fitness gains, inadequate whole fruit and vegetable consumption, drinking too many of your calories (coffee, smoothies), inadequate whole fruit and veggie consumption, high fat and processed food intake

question
think about building muscle and losing muscle
answer
hypertrophy and atrophy
question
are fatigue resistant, don't contract as rapidly and forcefully as fast-twitch fibers, are used in aerobic activities, move slow so doesn't get as tired, usually use blend of two fibers, endurance athletes use this
answer
slow-twitch fibers
question
fatigue more quickly than slow-twitch fibers, contract rapidly and forcefully, are used in anaerobic activities, a lot more force than slow-twitch, majority of fibers are set at birth- determine what you are better at, strength athletes use this
answer
fast-twitch fibers
question
a motor neuron and all the fibers it is connected to, as more force is needed the more motor units are recruited
answer
motor unit
question
muscular strength, muscular endurance, functional strength, progress is dependent on genetics- not everyone will improve to the same extent, depends on muscle fiber distribution (fast-twitch adapt more readily), increased muscle mass and size of muscle fibers, increased utilization and coordination of motor units, increased strength of tendons, ligaments, and bones, not only do the muscles get stronger but it may take longer to see results
answer
resistance/strength training
question
assessed by determining the 1-rep maximum (1RM)- the maximum resistance that can be lifted once, push yourself too hard too fast may hurt more than just the muscle but also the bone, tendon, etc.
answer
muscular strength
question
assessed by counting the maximum number of a muscular contraction
answer
muscular endurance
question
F: 2-3 days/week, I: 40-80%, T: one complete movement of exercise, T: endurance vs strength,
answer
FITT principle for resistance training
question
strength- how many you can do and how much weight, will not bulk you up, men will become bigger than women due to testosterone levels (10x more), women get lean and toned as the lack testosterone to build large muscles, helps maintain weight loss long-term due to increases in muscle/enzymes (BMR)
answer
Strength training
question
a combination of cardio and muscle fitness is the best exercise, cardio is effective for weight loss, will peak your metabolism for the time that you are active and the it returns to your resting metabolic rate
answer
Cardio exercise

answer
bals, balance boards, and bands
question
muscle contraction without a change in the length of the muscle
answer
static (isometric) exercise
question
muscle contraction with a change in the length of the muscle, concentric contraction- muscle applies force as it shortens (bicep curl), eccentric contraction- muscle applies force as it lengthens
answer
dynamic (isometric) exercise
question
Step 1: complete a need/wants analysis (goals, timeline, history), Step 2: select training variables (ordered exercises: big before small, high skill before low skill, core at the end, muscle balance: push-pull, multi-joint vs single-joint), Step 3: evaluation and review (progressive overload, sty on program for 3-6 weeks then change it up, use a journal, SMART goals), consider weight, current fitness level, and any special health concerns
answer
program design
question

answer
weight training safety
question
Before: most activity requires glucose, pre-fuel 1-2 hours before (carbs, low fat, protein, fluids), During: eat if exercise in morning or if longer than 45 min workout, 30-45 grams carb/hr, hydrate, 1lb=2 cups of water loss, losing >2% of body weight will have negative impact on quality, gains, and comfort, replace water with 3 cups per 1 lb lost during training, After: simple carb, protein, fluids, think about recovery plan, 30 minutes-1 hour body likes to have nutrients after workout, eat chocolate milk, PBJ, yogurt, fig newton, or fruit juice

answer
fitness trends for 2010
question
Pros: accountability (24 hour coverage), competition (with huge incentive), uses activity and change of food intake, motivating for participants/role models, turns them into active individuals, Cons: rate of weight loss, weight loss vs body composition, dangerous (if attempt these same ways), doesn't translate to real life, safe weight loss is 2lbs/week, may loose more weight if obese than people at normal weight
answer
The Biggest Loser
