What are the 4 Principles of Training to Increase Bone Strength?
Magnitude of the load (intensity) Rate of loading (speed) Direction of forces Volume of loading (# of repetitions)
26
How can Athletes stimulate bone formation? | 4 methods
1) Use exercises that directly load particular regions of the skeleton. 2) Use structural exs' to direct force vectors through the spine and hip and allow the use of greater absolute loads in training. 3) Overload the musculoskeletal sys, an progressively increase the load as the tissues become accustomed to the stimulus. 4) Vary exs selection to change the distribution of the force vectors to continually present a unique stimulus
27
Forces that reach or exceed a threshold bone formation stimulus initiate new what?
bone formation in the area experiencing the mechanical strain
28
Programs designed to stimulate new bone formation should have the concepts of what? How should those exercises be selected?
specificity of loading, progressive overload, and variation; and the exercises selected should be structural and weight bearing.
29
Adaptations of Tendons, Ligaments, and Fascia to Anaerobic Training: The primary stimulus for growth of tendons, ligaments, and fascia is what?
the mech forces created during exs
30
Adaptations of Tendons, Ligaments, and Fascia to Anaerobic Training The degree of tissue adaptation is what ?
proportional to intensity of exercise
31
Adaptations of Tendons, Ligaments, and Fascia to Anaerobic Training Consistent anaerobic exs that exceeds the threshold of strain does what?
stimulates connective tissue changes
32
Adaptations of Tendons, Ligaments, and Fascia to Anaerobic Training: Sites where connective tissues can increase strength and load-bearing capacity are what?
At the junctions between the tendon (and ligament) and bone surface. Within the body of the tendon or ligament in the network of fascia within the skeletal muscle
33
Adaptations of Tendons, Ligaments, and Fascia to Anaerobic Training Specific tendinous changes that contribute to size and strength increase include what?
an increase in collagen fibril diameter a > # of covalent cross-links within the hypertrophied fiber an increase in the number of collagen fibrils an increase in the packing density of collagen fibrils
34
Adaptations of Tendons, Ligaments, and Fascia to Anaerobic Training How can athletes stimulate connective tissue adaptations? 2 methods
Exercise of low to moderate intensity does not markedly change the collagen content of connective tissue. High-intensity loading results in a net growth of the involved connective tissues
35
Cartilage Adaptations to Anaerobic training Cartilage lacks what ? Why is Jt mobility vital?
its own blood supply and must depend on diffusion of O2 and nutrients from synovial fluid; therefore, joint mobility is linked with joint health
36
Cartilage Adaptations to Anaerobic training Movement about a joint creates changes in what where that drives what toward what?
Movement about a joint creates changes in pressure in the joint capsule that drive nutrients from the synovial fluid toward the articular cartilage of the joint
37
Cartilage Adaptations to Anaerobic training; how can athletes stimulate cartilage adapts? 3 ways
Weight-bearing forces and complete movement throughout the ROM seem to be essential to maintaining tissue viability. Moderate aerobic exercise seems adequate for increasing cartilage thickness. Strenuous exs doesnt appear to cause degnerative joint disease
38
Endocrine Responses and Adaptations to Anaerobic Training
Acute Anabolic Hormonal Responses Chronic Changes in the Acute Hormonal Response Chronic Changes in Resting Hormonal [ ]s Hormone Receptor Changes Acute CV responses to anaerobic exs
39
What hormonal response to anaerobic exs is critical for exs performance and subsequent training adaptations? Why is that important?
acute anabolic hormonal response since it upregs anabolic hormone receptors that are vital in mediating the hormonal effects.
40
acute
immediately after
41
chronic
continuously occurring after
42
What is Chronic Changes in the Acute Hormonal Response?
consistent resistant training may improve the acute hormonal response to anaerobic workout
43
Chronic Changes in Resting Hormonal [ ]s is what?
consistent chronic changes in resting hormonal concentrations [ ]s are less likely
44
Hormone Receptor Changes is what
Resistance training has been shown to upreg androgen receptor content within 48-72 hrs after the workout
45
Acute CV responses to anaerobic exs is what?
acute bout of anaerobic exs significantly increases the CV responses, especially if the the person uses the Valsalva maneuver
46
Acute anaerobic exs results in what ?
increased cardiac output, SV, HR; systolic BP, and blood flow to active muscles**.
47
Blood flow to muscle after acute anaerobic exs is not 100% true because:
When muscles are under tension, ischemia occurs cuz blood is being squeezed out like ringing out a towel. But, immediately following end of exs, reactive hyperemia, which is: supermax blood flow since they starved the blood.
48
Chronic CV adaptations @ Rest Anaerobic training leads to what?
decreases or no change in HR and BP
49
Chronic CV adaptations @ Rest Resistance training changes what
cardiac dimensions but not LVH like aerobic, they only increase mycardium
50

To improve muscular strength what kind of loads are most effective? and what for?
Heavier loads are most effective for fiber recruitment.
52
Improvement in muscular strength is due to what related effects of training?
The effects of training are related to the type of exs used, its intensity, and its volume.
53
To improve muscular strength with trained athletes, what needs to be done?
higher intensity and volume of exercise are needed in order for adaptations to continue.
54
Heavy resistance training with slow velocities of movement leads primarily to improvements in what ?
muscular strength
55
increases force output at higher velocities and rate of force development is what kind of training?

60
flexibility anaerobic training potentially can have what kind of an impact on flexibility? Primarily if the person has what initially?
positive impact poor flexibility

circuit training and programs using high volume with short rest periods
64
Anaerobic training improves motor performance. T/F
True
65
Anaerobic training improves motor performance; the magnitude of change is based on what ?
the specificity of the exercises or modalities performed
66
Resistance training has been shown to increase what?
``` running economy vertical jump sprint speed tennis serve velocity swinging and throwing velocity kicking performance ```
67
Overtraining is defined as what? what is the result due to ???
excessive frequency, volume, or intesity of training that results in extreme fatigue, illness, or injury ( which is often due to a lack of sufficient rest, recovery, and perhaps nutrient intake).
68
Overreaching (different from overtraining)
excessive training on a short-term basis
69
What Are the Markers of Anaerobic Overtraining? | 3
1) Psychological effects: decreased desire to train, decreased joy from training. 2) Acute E and NE increases beyond normal exercise-induced (sympathetic overtraining syndrome) 3) Performance decrements, although these occur too late to be a good predictor
70
What mistakes can lead to anaerobic overtraining ?
Chronic use of high intensity or high volume or a combo of the those two. Too rapid a rate of progression.
71

before actual decrements in performance occur.
