PT Exam Review - Unit7
HRmax method
(220-age) x training intensity assumes all people the same age should train in the same range
training HR
(HRR x 60-80%) / RHR
________ is a measurement of the body's ability to extract oxygen from blood.
(a-v)O2 difference
anaerobic training
(sprinting and lifting) improves FUNCTIONAL capacity
IT band syndrome
**Common among runners, accounts for 10% of running-related injuries -Injury to the ligament that runs along the lateral aspect of the hip and thigh; presents as lateral knee pain
aerobic training considerations: AGE
**Healthy, sedentary adults experience a decline of their VO2max by ~1% per year after age 25 -Attaining higher aerobic fitness during youth helps prevent the premature onset of functional decline -Sedentary, older adults who engage in aerobic activity experience improvements similar to younger individuals (10-20%)
Training duration:
**The higher the intensity, the lower the possible training duration Amount of time the participant is exposed to training stress; often measured by time-under-tension (only work periods count, not rest periods)
Plantar fasciitis
**most common cause of HEEL AND FOOT pain -plantar fascia that runs from the bottom of the foot is strained/inflamed
Circuit Training System
**time-saving, potential for high caloric expenditure, tolerable resistance levels across the whole body, and relatively short workout durations -up to 15 exercises(1-2/major muscle group)performed for predetermined time period or rep range in sequential fashion with transitional rest between or 15-30sec rest for beginners. **Full circuits can be performed for a designated time-period, or several cycles can be engaged with rest in between
Basic PNF technique
-10-sec passive stretch through a full ROM is performed directly followed by active-assisted pressure from the trainer -The client must resist the trainer by contracting the stretched muscle for 6 sec in the terminal position -The client relaxes, and the trainer holds the joint in the end position for a further (up to) 30-sec passive stretch
Detraining from resistance training causes (after 3 weeks):
-A reduction in muscle mass and fiber size -Increased capillary and mitochondrial density -Increased body fat -Increased aerobic enzyme with concurrent reductions in anaerobic enzyme concentrations -Loss of muscle strength, power, and endurance -reduction in neuromuscular efficiency **1 week of rest from an intense anaerobic training program can actually serve to improve performance; after this period however, the body begins to decline in its capabilities
Detraining
-ANaerobic training adaptations have better residuals than aerobic, exhibiting a slower reversal rate
Assessments that employ cross-joint movements can be very useful:
-Apley back scratch test -Single straight-leg hip flexion test -Thomas test -Trunk flexion/extension tests -Overhead squat assessment
Chondromalacia
-Associated with repeated impact, overuse, poor joint alignment or muscle imbalances -Impacts the articular hyaline cartilage of the PATELLA (knee cap) -Improvements can be seen with knee stability training and strengthening of the vastus medialis
Exertional rhabdomyolysis
-Breakdown and necrosis of skeletal muscle with subsequent release into circulation -Caused by excessively intense and high-volume training with inadequate rest; higher temperature environments and dehydration increase risk -Can have very serious consequences - organ damage, severe ischemia, cardiac arrhythmias, and even death **Increased prevalence due to cultural excitement surrounding extreme training programs
Lactate threshold/tempo training
-CONDITIONED individuals use this technique for improvements in stamina and lactate tolerance -Start at a steady-state pace as close to the lactate threshold as can be maintained -Pace is increased in short bursts of 2-5 min above lactate threshold before the client is physiologically forced to slow down to a recovery pace -The interval supra-lactate threshold bursts result in lactate accumulation, very high ventilation, and discomfort but help to optimize performance
METs
-Common method for conveying the energy demands of work -MET values above rest represents the amount of oxygen to support work REST = 1 MET (3.5ml/kg/min) the energy needed for resting metabolic homeostasis Example: running on a treadmill at 10 METs = 3.5 (rest) x 10 = 35 ml/kg/min
recovery period
-Duration of time in between exercise bouts; allows for energy system replenishment and adaptations to occur *Inadequate recovery increases the risk for injury, illness, and overtraining; excess recovery limits fitness improvements
Fartlek training:
-Fartlek - Swedish term meaning "speed play" -Is a type of INTERVAL training that incorporates unstructured fluctuations of intensity (common in spinning classes) -Fartlek courses include variances in speed, distances and surface angles (e.g., uphill, downhill running) to reduce boredom and provide a variety of training stimuli
General warm-up:
-Gross motor activation via basic movements such as jogging, jumping rope or cycling -Can last 5-10 mins depending on training intensity
things that cause IT band to become inflamed
-IT band, quadratus lumborum, or gluteus medius tightness -Uneven gait caused by running on uneven surfaces -High total weekly mileage -Quadricep, hamstring or gluteal weakness -Inadequate warm-up protocols -Increasing training distances too quickly
Performance (sport-specific) warm-ups:
-Includes actions and neural patterns to improve performance in a particular sport or activity -Duration can reach 15-20 mins (general movements followed by neural preparation) Example: jumping rope for 3 mins → mobility drills → muscle activations drills → moderate-intensity ballistics with 5-10% of training intensity
Benefits of a warm-up:
-Increased neural sensitivity and transmission speed -Greater movement economy and ROM -Increased oxygen and blood delivery -Increased enzymatic and metabolic activity -Heightened muscle temperature
genetic benefits
-Larger stroke volumes -Greater concentrations of type I fibers -Greater mitochondrial and capillary density -Higher myoglobin concentrations -More efficient neural and metabolic pathways
Age: Older adults
-Loss of muscle mass, or SARCOPENIA, can greatly reduce function -Older adults show as much as 40% lower power output measures, fatigue faster, and lose mobility due to connective tissue changes -The risk for falls and bone fractures increases with age-related losses in speed, flexibility, stability, and balance **Resistance and power training is very useful for maintaining function and independence
Strength-Power Phase
-May emphasize strength or power preferentially, but includes a shift toward increased movement velocity **An integrated approach to strength/power can best serve clients with health and fitness goals (rather than athletic development)
what aerobic improvements can occur within 7 days of detraining?
-Mitochondrial, hemoglobin, and capillary densities revert back to pre-training conditions -Cardiac output/stroke volume is reduced 14 days off can result in a reduction of VO2max by 1 MET (3.5 ml/kg/min)
Exercise selection:
-Must select exercises which best reflect the needs analysis; each activity must match a specific need or goal -Need for skill acquisition as well as client-specific limitations and interests must be considered
contributing factors of bursitis
-Overuse or injury -Incorrect posture at work or rest -Poor conditioning before exercise or sports participation -Abnormal or poorly-positioned joints/bones (e.g., leg length discrepancy)
principles of exercise program design can include:
-PROGRESSIVE PREPARATION: acclimating the body to more challenging work levels -ENERGY CONTINUUM: the predominant energy system used to fuel the work -EXERCISE SELECTION: type of exercise or modality selected -PERIODIZATION: phasic adaptational-based system used to maximize desired response -EXERCISE ORDER: sequence of exercises -TRAINING FREQUENCY: # exercise bouts/week -TRAINING DURATION: length of time engaged in physical effort -TRAINING INTENSITY: level of effort performed relative to capabilities -REST PERIODS: duration of time between each physical effort -TRAINING VOLUME: quantity of total work performed -RECOVERY PERIODS: duration of time between exercise sessions
PRIORITY system
-Perform exercises for deficient muscle groups or health limitations at the beginning of each session to ensure they receive adequate attention with maximal energy availability -Often used during the general fitness/preparation phase of training **Good for new or novice clients or those returning to exercise
benefits of a cool down:
-Prevention of blood pooling -The maintenance of cardiac output via venous blood return to the heart -Reduction of blood/muscle lactate and stress hormones -Reduced risk for cardiac irregularities or dangerous event -Improved overall recovery
program tracking
-Program components should be tracked on a daily basis to gauge its effectiveness and monitor for any problems that may need to be addressed -allows for proper application of progressive overload; trainers should review the intensity, volume, rest intervals used, and specificity of stress to address any problems that arise -LIABILITY: if a trainer is involved in litigation, the program components are often reviewed for appropriateness (no tracking = no defense)
4 methods body uses to cool itsel
-RADIATION: heat loss into surrounding air through the skin -CONVECTION: heat loss via movement of cooler air across skin -CONDUCTION: heat loss via direct contact with something colder than the body (water,bench) -EVAPORATION: heat loss via sweat- (derived from blood plasma) that pulls heat away from body
Mechanisms behind aerobic detraining:
-Reduced stroke volume and left ventricle mass - back to pretrained levels -reduction in blood plasma -Changes in metabolic enzymes -decrease in insulin sensitivity -Mitochondrial density and oxygen extraction losses occur after 3 weeks
why can impingement occur?
-Repeated overhead lifting or improper lifting technique -Shoulder joint instability -Excessive pushing exercises without enough pulling which pulls the shoulders forward -Rotator cuff and scapular stabilizer weaknesses -Posterior capsule tightness -Postural distortions
Cardio circuit training:
-Require exercisers to perform steady-state aerobic activity with intermittent resistance training activities -Can be replicated in a gym using anaerobic stations interspersed with short bouts of various types of cardiovascular training EX:park jogging trail with intermittent stations to stop and perform calisthenics such as pull-ups or push-ups
Age: Children/adolescents
-Safe resistance training in the form of simulated play does not stunt growth or cause any negative physical issues (many play activities place more stress on bone than resistance training) -BW exercises using pushing, pulling, climbing, and ballistic activities in play-based programs are encouraged and well-received -Children do well using SHORT-burst activities rather than continuous work **Lower attention spans require engaging activities and thermoregulatory capabilities must be considered
Interval training
-Takes advantage of variations in HR and resistance/speed -More effective for inducing greater CRF adaptations; the body always adapts to the highest perceived stress (>20% increased adaptation rate) **May be more useful within personal training due to greater adaptations and caloric expenditure in a shorter period of time
causes of plantar fascitis
-Tight calves -Achilles tendinosis -An abrupt increase in training volume -Improper arch support -Prolonged walking or running -Obesity
Drop/Strip Set System
-Used for HYPERTROPHY and maximizing muscle recruitment -2-3 sets of the same exercise are commonly performed in a row - with only the time it takes to drop or "strip" the weight down serving as transitional rest between efforts -Each set is performed for a designated number of reps or to volitional failure; they are sometimes added to the end of pyramid
Cross training
-Uses various modes to limit the risk for injury and boredom **running, cycling, swimming, elliptical work, stair climbing, rowing
Specific warm-up:
-Utilizes actions and musculature to be used during activities that reflect the client's goal -Specific muscles and neural patterns are primed for maximal intensity effort(1RM) 12 reps at 65% 10 reps at 70% 8 reps at 77.5% working sets 3x6 at 82.5%
aerobic training considerations: GENETICS
-account for 50% of differences in improvements between individuals
Static flexibility
-active stretching -active-assisted stretching -PNF- proprioceptive neuromuscular facilitation -active-isolation stretching
improved ROM and participation in flexibility routines can positively impact stress how?
-alleviation of tension -reduction of psychomotor distraction -improved state of overall relaxation
dynamic stretches
-allow ROM gains related to SPECIFIC movements employed during training -popular in sports as an effective preparation model -provide for both a warm-up and improved ROM outcomes
As the focus on strength and power merge, repetitions per set can shift into time-specific work-rest bouts
-ballistic push-ups performed at max speed for 15sec w/90 sec rest -power cleans using 4 reps @80% 1RM w/ 2 min recovery -high-knee lateral cone step using intervals of 10 sec on, 30 sec off
periodization
-body adapts more efficiently when adaptations are strategically built upon each other -Reflects a logical method of organizing training into sequential phases and cyclical time periods -Allows adaptation residuals to be strategically built upon each other for maximal gains over time -Desired adaptive responses associated with training are referred to as supercompensation
steady state training
-client performs at a set pace/ intensity so they maintain a steady HR -HR will not vary by >5bpm as oxygenated blood supply is meeting the demand of working cells and tissues **Can be performed for longer periods and is useful for developing baseline CRF and long-distance training
