Q

how is cardiac function changed with aerobic?

A

-we see left ventricular hypertrophy due to more blood flow because of an increase in pre load due to volume load from aerobic exercise, this causes:
1 decreased resting heart rate and decreased submax HR but max HR is unaffected
2 increased resting, submit, and max SV(can pump more out)
unaffected rest and sub max Q but increased max Q from increased SV

Q

In what ways does circulation (vessels not the heart) change due to aerobic exercise?

A

-capillary density increases to allow more blood to carry O2 through them (increased number?)
-there is greater dilation of existing capillaries due to EDRFs released to override the SNS, this also allow more distribution of blood because there are more “highways”
-blood volume increases (increased SV) but specifically plasma volume and red blood cells
Decreased resting and submit SBP/DBP - you are clearing out the vessels of blood to distribute it

How is Ve and the respiratory system changed with aerobic exercise?
- decreased submax Ve (at same workload ex 100W: pre 100L/min post=90 L/min) - increased max Ve (incrased workload ex 175W pre=175L/min 250W post=200L/min)
26
how is exercise perfromance measured and how will it change with aerobic exercise?
measured with Vo2 max - increases aerobic power - improved submax endurance capacity (can run longer at sub max speeds after aerobic training) - decreases metabolic cost for submit workloads (Vo2 decreased and kcal burned decreased at same workload pre and post training)
27
what are the FITT for resistance training?
F: >= 2 sessions per week with 24-48 hours of rest after each session if workout targets whole body (progressive overload Hans principle) I: >= 60-70% 1-RM for all around improvements T: not for time, usually measured by sets and reps-- 8-10 exercises, 1-3 sets x 8-15 reps. 1 min rest between sets (recommendations to hit all body/major muscle groups) T: Isotonic resisted movements (eccentric and concentric) ***see more neuromuscular adaptations improve with resistance training
28
What specific training recommendations/goals can be seen with resistance exercise?
- muscle endurance - muscle hypertrophy - muscle strength - muscle power
29
How could you train muscular endurance?
GOAL: to stress muscles continuously - moderate to large volume (sets*reps=volume) = 2-3 sets * 12-25 reps - low to mod intensity = <65% IRM - Little recovery between sets = less than 30 sec
30
How would one train muscle hypertrophy with resistance exercise?
GOAL: Putin a lot of work - Large volume3-6 sets * 8-12 reps - moderate intensity- 65-85% IRM - low-mod recovery- 30 sec to 1.5 min
31
how would you train muscle strength?
FOCUS: training the muscle to produce maximal force - low-moderate volume- 2-6 sets* less than 6 reps - high intensity- greater than 85% IRM - full recovery between sets- 2-5 min (because of High Frequency Fatigue need rest)
32
how to train muscle power?
FOCUS: adding velocity-specific training to strength base (explosive lifting) - low volume 2-6sests * ^ keeps - Highest intensity-55-75% IRM but lifting FAST to get power (power=work/time) - full recovery- 2-5 min
33
What is isometric training
confined ROM but produces greater increases in muscular strength than isotonic
34
What is eccentric resistance training?
causes huge increases in muscle hypertrophy and strength. | -also causes large damage to the muscles= lower volume and more resistance between sessions.
35
Explain plyometric training.
- causes large increases in muscle power - big damage from eccentric loading - doing resistance moves as fast as possible, uses a strength shortening cycle. - should develop a strength base 1st
36
Explain circuit training and its benifits/drawbacks
- performing multiple ressitance exercises in succession with little or no rest in between sets. - acute responses blend resistance and aerobic( increase heart rate and BP). - good for people who have little time, can see overall improvements - but: wont optimally develop one specific response (VO2, strength, hypertrophy)
37
what is electrical stimulation?
contraction of muscles via electrical stim. from motor nerves. -good for rehab settings because the external stimulation can help them learn to use muscles again.
38
what are the neuromuscular recruitment changes in resistance training?
1. improved motor unit syncing (doing over and over) 2. Increased motor unit recruitment- higher intensity contractions = use higher orders 3. improved rate coding 4. Co-activtion of muscles MAYBE: 5 more efficient reciprocal inhibition 6. reduced autogenic inhibition (due to handling higher force outputs without shutting off)
39
explain muscular strength gains early and later
early: due to neuromuscular recruitment and learning a motor pattern later: from anatomical and physiological changes within muscle fibers
40
Explain transient vs chronic changes with muscular hypertrophy
transient: muscle fibers larger due to retention of water at first chronic changes: more stuff inside of the muscle ( myofiliaments, myofibrils, increased sarcoplams and cellular contents. or increased thickness of connective tissues
41
is hyperplaisia (increasing # of muscle fibers) a component of muscular hypertrophy?
no, it has not been documented in humans. | the numbers of fibers dont change, but you can further develop the ones that we do have
42
What muscle fiber changes happen in resistance training?
type 2x-2a | -increased size and function of all types
43
what metabolic changes happen with resistance exercise?
- increased immediate and glycolytic enzyme activity (hexokinase) - increased mitochondrial respiration at rest (EPOC) - increased storage and utilization of CrP and glycogen (using immediate systems more frequently) - no change in Vo2 max, but maybe with circuit - increased lactate threshold with circuit
44
what cardiac function adaptations happen with resistance?
resistance training causes pressure load, so: - increased BP leads to LV hypertrophy - unaffected resting, submax and max HR,SV, Q
45
how does circulation change with resistance training?
- greater dilation of existing capillaries - improved blood distribution (EDRFs increase vasodilation) - decreased resting SBP/DBP
46
how does resistance training impact the respiratiory system?
- no notable changes with whole body training but you can train your respiratory muscles which would: - increase strength and endurance, FVC and TLC * * this would not effect athletes
47
HOw is exercise performance influence by resistance training?
depending on how you train it could: - increase muscle strength - increase endurance - increase power - increase hypetrophy - increase anerobic power (for circuits or high entensity)
48
What are the FITT for general anaerobic training
F: 3-4 per week I: >= 100% VO2 max (all out depending on interval length, longer = less force output/ inverse relationship) T: 3-10 intervals of 5-30 seconds each with work/rest ratio of 1:5-6 T: any mode that permits all out activity (running, cycling, swimming)
49
what neruomuscular recruitment changes with anaerobic training?
``` same as resistance: =improved motor unit syncing -improved rate roding -increased motor unit recruitment -co-activation of muscles -more efficient recipricol inhibition -reduced autogenic inhibition ```
50
what muscle fiber changes with ana?
some type 2x-->2a - increased size and function of type IIa and IIx - decreased type 1 size and function depending on mode (slower anaerobic but more force= may have hypertophy of type 1 but faster with less force may have a decrease in size of type 1.)
51
how does metabolism change with anaerobic?
increased activity from : immediate glycolytic oxidative enzyme activity *because it taxes all systems in some way. if you do longer sprints or a longer duration sprint workout it will effect mitochondrial -increased storage and utilization of CRP and glycogen -no change/small increase in VO2 (wont see if doing small intervals) -lactate threshold- depends on interval length
52
how does cardiac function change with anaerobic?
- decreaed resting HR - improved HR recovery - unaffected resting submax and max SV and Q
53
what circulation changes with anaerobic?
same as resistance: - may increased capillary density - greater dilation of existing capillaries - improved blood distribution - decreased resting SBP and DBP
54
How does the respiratory system increase muscle strength and endurance with resistance training?
it depends on the interval length and how hard you are breathing
55
how is exercise performance changed with anaerobic training
- increased aerobic power - increased anaerobic power - decreased fatigue index (power drop off over time) - increased muscle power - improved metabolic cost at submax workloads (lower VO2 or increased neruomuscular efficiency) - increased muscle strength (if training slowerwith more force)
56
What is FITT for flexibility training to improve flexibility?
F: 2-3 sessions per week I: hold stretches to point of mild discomfot T: 15-30 sec per rep, 2-4 reps per muscle group T: static, active stretching with passive assistance at end of ROM or PNF stretching combo
57
what is FITT to improve performance?
F: right before exercise or sport perfromance I: ROM should not extend beyond mild discomfort, and not higher than moderate intensity T: depends on the drill T: active, dynamic stretching drills *tunes muscle spindles **dont do static stretching
58
what type of stretching involves an external force to move a joint through its range of motion?
Passive stretching. external force=table/partner/strap
59
what stretching involves contraction of agonist muscle to move a joint through its ROM to stretch target muscle/muscle group

64
what are the two types of flexibility training?
yoga- imrpoves muscular strength, muscular endurance and flexibility (also spiritual and mental domains pilates- muscular strength, endurance, flexibility, and posture
65
what neruomuscular recruitment factors change with stretching?
with dynamic active stretching: - improved motor unit syncing - increased motor unit recruitment - improved rate coding - co-activation of muscles with all stretching: - re-tuned muscle spindles and GTOs. - descencitize spindles and re-tune for flexibility
66
