Study Notes
Age-Related Differences and Exercise: Youth
- Exercise benefits youth by increasing muscular strength, improving cardiometabolic risk factors, aiding weight control, strengthening bones, enhancing psychological well-being, and potentially preventing sports injuries.
- Exercise is positively linked to cognition and academic success.
- Resistance training increases muscular strength, power, and endurance, improves psychosocial parameters, motor skills, sport performance, insulin sensitivity, cardiac function, and bone mineral density.
- Resistance training decreases body fat and risk of injury.
- Resistance training likely benefits growth at all stages of development when appropriate guidelines are followed, and does not affect the genotypic maximum for height.
Physiological Responses to Exercise: Youth vs. Adults
- Youth exhibit quantitative differences in acute exercise responses compared to adults.
- Youth have lower absolute oxygen uptake but higher relative oxygen uptake.
- Youth have higher heart and respiratory rates.
- Youth have lower cardiac output, stroke volume, systolic and diastolic blood pressure, minute ventilation, and anaerobic capacity.
- Prepubescent children with immature skeletons should avoid excessive vigorous exercise.
- Children's lower anaerobic capacity limits their ability to sustain vigorous exercise.
Chronological vs. Biological Age
- Physical development varies significantly among individuals of the same chronological age.
- Chronological age is the stage of maturation by months or years.
- Biological age can be measured by skeletal age, somatic maturity, or sexual maturation.
- Maturation degree relates to fitness measures like muscular strength and motor skills.
- There is no scientific evidence suggesting that physical training delays or accelerates growth or maturation in youth.
Puberty and Physical Development
- Differences in physicality relate to variations in growth timing, tempo, and magnitude during puberty.
- Puberty onset varies (8-13 years for girls, 9-15 years for boys), with girls typically starting about 2 years earlier.
- Menstruation onset in girls indicates sexual maturation.
- Indicators of sexual maturity for boys are the appearance of pubic and facial hair, and a deepening voice.
- Maturity assessments help evaluate growth and development patterns, and match children fairly for fitness testing and athletic competition.
- Adequately nourished kids will not experience growth or maturation delays or acceleration from physical training.
- Weight-bearing activities creating compressive forces are essential for skeletal remodeling.
- Around age 12 in females and 14 in males peak height velocity occurs, increasing the injury risk for young athletes.
- Center of mass changes, muscle imbalances, and muscle-tendon unit tightening are potential overuse injury risk factors during the pubertal growth spurt.
Muscle and Bone Growth
- Muscle mass is about 25% of a child's body weight at birth, increasing to about 40% by adulthood.
- Increases in muscle mass and shoulder width occur during puberty in boys due to increased hormonal concentrations.
- Estrogen increases body fat deposition, breast development, and hip widening in girls.
- Muscle mass increases continue through adolescence in girls, but slower than in boys due to hormonal differences.
- Muscle mass increase is due to individual muscle fiber hypertrophy, not hyperplasia.
- Peak muscle mass occurs between 16 and 20 in females and 18 and 25 in males, and is less affected by resistance training, diet, or both.
- Bone formation occurs in the diaphysis (central shaft) of long bones, then in the growth cartilage at the epiphyseal growth plate, joint surface, and apophyseal plate.
- Long bones stop growing when the epiphyseal plate is fully ossified.
- Bones typically begin to fuse during adolescence.
- Girls generally achieve full bone maturity about two to three years before boys, with most bones fused by the early 20s.
- Vulnerability of growth cartilage to trauma and overuse is a particular concern in children.
- Growth cartilage injuries can disrupt blood and nutrient supply to the bone, causing permanent growth problems.
- Injuries from falls or repetitive stress may cause a ligament tear in adults, but an epiphyseal plate fracture in children.
- The highest incidence of epiphyseal plate fractures occurs around peak height velocity.
- Pre-adolescent children may be at less risk for epiphyseal plate fracture than adolescents experiencing a growth spurt.
- Younger children's epiphyseal plates may be stronger and more resistant to shearing forces.
- Growth cartilage damage can impair bone growth and development, but the risk can be reduced with appropriate exercise techniques, sensible training load progression, and qualified instruction.
- Strength is essentially equal between boys and girls during pre-adolescence, but hormonal differences during puberty accelerate strength gains in boys and plateau strength development in girls.
- Peak strength is usually attained by age 20 in untrained women and between 20 and 30 in untrained men.
- Nervous system development is an important factor in the expression of strength in children.
- Incomplete myelination of nerve fibers prevents successful performance of fast reactions and skill movements, limiting high levels of strength and power.
- Children improve performance and skills requiring balance, agility, strength, and power as the nervous system develops.
- Children should not be expected to respond to training or reach the same skill level as adults until full neural maturity due to incomplete motor neuron myelination until sexual maturation.
Special Considerations in Youth
- Unstructured active play should be included in physical activity for young children.
- Activity should consist of moderate and vigorous bursts, alternating with brief rest.
- Youth should avoid heavy exercise in hot, humid environments due to thermoregulatory systems.
- Overweight or physically inactive children that may not be able to achieve 60 minutes of moderate to vigorous intensity physical activity should begin with moderate intensity activity as tolerated, and gradually increase the frequency and time to achieve the 60 minute goal.
- Vigorous intensity should be gradually added at least three days a week.
- Resistance exercise is a safe and effective conditioning method during childhood (before secondary sex characteristics develop).
- Resistance exercise can increase muscular strength beyond growth and maturation alone, if intensity and volume are adequate.
- Variability in strength gain is normal, may be due to biological age, program design, quality of instruction, or background physical activity level.
- Training-induced strength gains in children are impermanent, and tend to return to untrained control group values during detraining.
- Neural factors can increase strength owing to increases in motor unit activation and synchronization, enhanced motor unit recruitment and firing frequency.
- A multiple-modality approach is recommended.
Youth Resistance Training Guidelines
- Use low to moderate intensities for 6-15 repetitions, 1-4 sets per exercise.
- For upper and lower body power exercises use 1-3 sets of 3-6 repetitions.
- Training should occur 2-3 nonconsecutive days per week.
- Gradually increase to higher intensities or loads (by 5%-10%) as technique improves.
- Use single- and multi-joint exercises, including weightlifting derivatives.
- A multiple-modality approach is recommended with free weights, machines, and associated equipment.
- Each child should understand the benefits and risks of resistance training and have a competent and caring, strength and conditioning professional.
- The exercise environment should be safe and free of hazards and equipment should be appropriately sized to fit the child.
- Perform dynamic warm-up exercises before resistance training.
- Static stretching exercises should be performed after resistance training, when appropriate.
- Children should be carefully monitored for stress tolerance.
- Begin with light loads.
- Increase resistance gradually by 5-10% as technique and strength improve.
- Adult spotters should be nearby to assist the child in the event of a failed rep.
- The training program should be systematically periodized throughout the year to ensure varied training stimulus with adequate rest and recovery between cycles.
Resistance Training: Risks and Concerns
- Resistance training is relatively safe compared to other sports and activities.
- One rep max testing in children and adolescents is safe if appropriate testing guidelines are followed.
- This includes adequate warm up periods, progression of loads, and close supervision.
- The primary focus must be on developing proper form and technique.
- Its important to focus on intrinsic factors such as improvement, personal success, and having fun.
- Correct feedback should be delivered at the correct time and in the correct manner.
- Technical performance should be regularly evaluated by a trained observer.
- Practitioners could use field-based measures of different jump protocols or hand grip strength to obtain surrogate strength measures without repetition.
- Jump and grip tests have correlations with one rep max values in youth.
- Along with the rate of progression, the quality of instruction is important in the development of youth resistance training.
- Increasing resistance or the number of sets is necessary to make continual gains, but every session does not need to be more intense or higher in volume than the previous one.
- Keeping the program fresh and challenging is important.
- Age-Related Differences and Implications for Exercise – Older Adults
Older Adults and Exercise
- Health and functional status are often better indicators of ability to engage in physical activity than chronological age.
- Older adults are individuals age 65 and older and individuals age 50-64 with clinically significant conditions or physical limitations that affect their movement of physical fitness.
- Bone and muscle loss with age increases the risk for falls, fractures, and long term disability.
- Bones become more fragile with age because of a decrease in bone mineral content that causes an increase in bone porosity.
- Hip, spine, and wrist fractures increase during falls.
- Advanced aging is associated with sarcopenia (loss of muscle mass or strength).
- CT Scans reveal that after age 30, there's a decrease in the cross-sectional areas of individual muscles along with a decrease in muscle density, reductions in tendons compliance, and an increase in intramuscular fat.
- These changes seem to be predictable consequences of advancing age and are the most pronounced in women.
- Muscle atrophy with aging appears to be the result of physical inactivity and gradual and selective deinnervation of muscle fibers.
Older Adults and Exercise Prescription
- General exercise prescription principles apply.
- A distinction should be made relative to intensity.
- For older adults, activities should be defined relative to an individual’s physical fitness within the context of a perceived physical exertion scale Moderate intensity.
- For healthy adults moderate to vigorous intensities are defined relative to METs with moderate intensity activities defined as 3-5.9 METs and vigorous intensity activities greater than or equal to 6 METs.
- For older adults, activity should be defined relative to an individual’s physical fitness within the context of a perceived 10 pt physical exertion scale, which ranges from 0 (an effort equivalent to sitting), to 10 (an all out effort), with moderate intensity defined at 5-6 and vigorous 7 or greater.
Physiology: Aging and Impact of Resistance Training
- The effects of aging result in decrease for the following: muscular strength and power, muscular endurance, and muscle mass and fiber size.
- Resting metabolic rate, body fat level and function decrease.
- The following increase due to resistance training: muscular strength and power/endurance, muscle mass/ fiber size and muscle metabolic capacity.
Resistance Training for Older Adults
- The optimal training protocol for improving muscular strength and power in seniors is not known Dose-response relationship between training intensity and improvements in muscular strength and power Higher-intensity resistance training is more effective in developing maximal muscle strength than moderate- or low-intensity training
Program Considerations for Older Adults
- Patients that are able should use free weight, and multi-joint resistance training exercises.
- Resistance machines may be used in early stages due to balance and flexibility limitations.
- Avoid performing the Valsalva Maneuver during resistance training to avoid an abnormal increase in BP.
- Should be allowed 48-72 hours of recovery between exercise sessions Ensure programming exercises are not technically too challenging as this can increase the likelihood of a training related injury
- Resistance training stimulation should never be increased at the expense of a technical competency Training frequency of twice per week is recommended at least during the initial adaptation period Concerns to be aware of
- Pre existing medical conditions
- Prior training history
- Nutrition Adequate amounts of protein are essential for muscle hypertrophy in older adults.
- Inadequate intakes of macronutrients and micronutrients are associated with potential negative health consequences.
- Including fatigue, compromised immune system, and delayed recovery
Program Considerations for Older Adults
- Gradually progress from 1 set of 8-12 repetitions at relatively low intensity; e.g., 40-50% 1RM, to higher training volumes and intensities; e.g., 3 sets per exercise with 60-80% of 1RM Power training- High-velocity power exercises can be gradually incorporated 1-3 sets per exercise with a light to moderate load; 40-60% 1RM, for 6-10 repetitions with high repetition velocity
Sex-Related Differences and Implications for Exercise
- Absolute strength: women generally have about 2/3 the strength of men Absolute lower body strength of women is generally closer to male values as compared to the absolute values for upper body strength.
- Relative strength: strength expressed relative to muscle cross-sectional area and no significant sex differences
- Power output: women generally have about 2/3 power of men
- Differences between two women or two men may be greater than differences between a man and a woman.
Female Athletes: Responsiveness to Resistance Training
- Respond to resistance exercise in similar ways to males
- Can increase their strength at the same rate as men or faster Although absolute gains in strength are often greater for males, relative increases are about the same or greater in women
- However, this may reflect that baseline neuromuscular levels are lower on average in females
Program Consideration for Women
- No reason why resistance training programs for women need to be different from those of men
- The only difference is generally the amount of absolute resistance used for a given exercise which is based on the individual’s strength capabilities One area of concern regarding prescription of resistance training programs for females relates to the development of upper body strength Because the upper body absolute strength of women tends to be less than that of men, emphasizing development of upper body is especially worthwhile for female athletes who play sports that require upper body strength and power Two areas of concern for females
Development of upper body strength
- Prevention of sports-related injuries, especially of knee Gender and Flexibility- Females tend to be more flexible than males.
- This is due to hormonal differences , anatomical differences, muscle mass, and composition and activity levels of training
- In females Estrogen and relaxin are found in higher levels and contribute to greater joint laxity and flexibility Estrogen helps maintain elasticity connective tissues while relaxing, especially during pregnancy increases laxity
- Women typically have a wider pelvis and different muscle attachment sites which can affect flexibility The structure of female joints, particularly the hips, is often more conducive to greater range of motion.
- Mend generally have greater muscle mass and more muscle stiffness which can limit flexibility
Endocrine Response to Exercise
- General adaptation Refers to the adrenal gland’s response to stressors This response begins with an initial alarm reaction that includes a reduction of function, but is followed by an increase in resistance to the stress above the previous baseline
- This increased resistance to stress is referred to as adaptation When the stressor is exercised, it's called a training adaptation
- The key to continued beneficial adaptation to the stress is the timely removal of the stimulus or exercise so that the function can recover and then you can reapply the stress and create a progressive overload
Adaptations in the Endocrine System
- Increased sensitivity and reduced levels occur in coordination with Adaptation of insulin.
- Adaptation glucagon results increase secretion during exercise and improved regulation in the endocrine system.
- Growth hormones increase secretion during exercise and enhance regulation of thyroid hormones.
- Endorphins increased levels in response to high-intensity exercise- Increased secretin during exercise, adaptation cortisol and improved regulation.
Endocrine Adaptations to Aerobic Exercise
- Increases in hormonal circulation and changes at the receptor level are specific responses to aerobic exercise and receptor level, both the number of receptors and the turnover rate Higher intensity aerobic training increases the absolute secretion of many hormones in response to maximal exercise
- Response patterns to max exercise appear to help the athlete’s ability to tolerate and sustain prolonged high aerobic exercise intensities When exercise intensity is very high and exercise duration is very short (5-10 seconds), only peripheral blood hormone concentrations occur, like epinephrine or norepinephrine
- Aerobic training, especially running, is often associated with an increased net protein breakdown from the muscle, brought about in part by stress induced cortisol secretion and the body’s attempt to offset that by increasing anabolic responses and testosterone and insulin like growth factors
Neuromusculoskeletal Response to Exercise.
- Neural Adaptations to Training increased motor unit and description is more motor units are activated during muscle contraction.
- Reduction in Co-contraction of antagonist muscles and increase activation of agonist muscles and Improved intermuscular coordination.
Neural Adaptations to Anaerobic Training.
- Recruitment of fast-twitch motor units is elevated.
- Reduction in inhibitory mechanisms Neural adaptations typically occur before any structural changes in muscle are apparent. As level of force rises, or when a new exercise or movement is being learned, the primary motor cortex activity is elevated in an effort to support the need for more neuromuscular function.
- Adaptations to anaerobic training method are reflected by substantial neural changes in the spinal cord, particularly along the descending corticospinal tracts
Neural Adaptations to Anaerobic Training
- Size principle is represented between motor units, twitch force, and recruitment thresholds.
- motor units are also recruited in an ascending order according to the recruitment thresholds and firing rates. The Central Nervous System also plays a role in an athlete's training.
Other Motor Unit Adaptations
- Cross-Education,Unilateral Resistance Training/Exercising Muscle produces Increased Strength and Neural Activity in the Contralateral (opposite resting)Muscle.
- Efficiency is increased and athlete produces more efficient movement during the activity with lower energy expenditure.
Neuromusculoskeletal Response to Aerobic Training
Performance – Chronic Physiological Adaptations to Aerobic Training- Muscular strength No change No change- Muscular endurance Increased low power output.
- The fundamental adaptive responses to aerobic endurance training are an increase in the aerobic capacity of the trained muscles. The adaptation occurs as a result of glycogen sparing Less glycogen during exercise and increased fat utilization within the muscle which prolongs the performance at the same intensity. The onset of blood lactate accumulation occurs at a higher percentage of the trained athlete’s aerobic capacity.
Muscle Fibers – Chronic Physiological Adaptations to Aerobic Training
- The muscular component of an aerobic endurance training program involves submaximal muscle contractions over a large number of repetitions with little recovery, therefore, the relative intensity is very low and the volume is high This manner of training encourages relative increases in aerobic potential that are similar in both type 1 and type 2 fibers.
- Fibers possess an oxidative capacity greater than that of type 2 both before and after trainingSelective hypertrophy of type 1 fibers occurs due to the increased recruitment during aerobic activities, although the resulting cross-sectional diameter is not as great as that seen in type 2 fibers adapted to resistance exercise.
Metabolic Energy Stores – Chronic Physiological Adaptations to Aerobic Training
Stored ATP Increased- Stored creatine phosphate Increased Stored glycogen Increased- Stored triglycerides Increased
For bones bones Connective Tissue – Chronic Physiological Adaptations to Aerobic TrainingStrength Variable- Bone density No change or increased
Body Composition – Chronic Physiological Adaptations to Aerobic Training
- The oxygen transport system must, rather than the limitations of the musculoskeletal system limit body restrictions to a new exercise intensity
Performance – Physiological Adaptations to Resistance Training
- Increased- Muscle Fibers – Physiological Adaptations to Resistance Training
The process of hypertrophy Is when Muscle Hypertrophy has also shown to reduce mitochondrial density increased the number of muscle fibers via longitudinal fiber splitting in response to high intensity resistance training Type 2 fibers manifest greater increases in size than type 1 fibers with resistance training
Muscle – Structural and Architectural Changes
- In pennate muscle, resistance training has been shown to increase the angle of pennation, with strength trained individuals displaying larger pennation angles in the triceps and vastus lateralis muscles compared to untrained individuals.
- With trained individuals is the Pennation Angle, pennation angle affect the force production capabilities as well as the range of motion
There are increased metabolic in the Muscle.
Bone Adaptation
- In order to promote bone formation, athletes should use specific programming of acute training variable in order to maximize optimal adaptations Select multi-joint structural exercises that involve many muscle groups at once Avoid isolated single joint maintenance
- Forces that reach or exceed a certain threshold stimulus can initiate new bone formation in the area experiencing strain
The Cardiopulmonary Response to Exercise
- Reduces Reduces the Reduces the Cardiovascular response response response
Chronic Cardiovascular and Respiratory Responses to Aerobic Training
- Adaptations result from local neural and chemical adaptations to the specific muscles trained ventilation Ventilation training
Introduction to Pain
- Pain is the number one reason a person seeks medical attention and is higher for low back pain, Migraines, and Peripheral pain.
The Dimensions of Pain- Negative emotion Cognition
Occurs more often in Somatic parts on the Body.
Acute Pain
- Is a Direct Result of Tissue Damage
Chronic pain is difficult to treat and responds best to an Interdisciplinary medicine
Pain Terminology
- Secondary hyperalgesia- A Term used to describe pain from a non-Nociceptive Stimuli
Occurs During Conditions A, B, C, D.
Introduction to Pain Mechanisms and Theories
- Nociplastic is due to disturbance of central pain by increased excitability and decreased inhibition.
- Neuropathic has to with problems with the somatosensory system
- Some refer to psychosocial pain which would be more of social or psychological.
- Neuromatrix theory is a large widespread network of neurones integrates both the thalamus and limbic system.
Introduction to Pain Assessment
- Goal is to provide sufficient and accurate data that affects one’s previous pain experiences
Characteristics of Pain Location: Can be in more than one location. Description: Using alternative words used by the patient.
Memory of Pain
Memory recall can affect pain intensity. Pain Intensity is influences by multiple factors
Verbal reporting vs Nonverbal reporting
- Self reported is best method
- When unable to self-report pain, the reliance on others to recognize is needed
Types of pain
- Observation and physiological parameters
Range of Motion
- Range is therapeutic used for maintain joint, minimize the loss of tissue, and flexibility Passive ROM is the movement of a segment that the force is made external and muscular contraindications is little to NONE.
- Therapist must minimize the effects of the formation of tissues and muscles for recovery for an active range of motion.
- It doesn’t prevent muscle atrophy
Acute and Active Motion
- Active and active-assistive ROM is used when active motion would compromise an injured repair of the muscle
Precaution on ROM
- The condition is bad to the patients health.
- ROM should not be done when there is tear in the joints such as tissues. However in pain free range rom has been a healing process.
- Must make an understanding what they are in for.
The Application of Active and Active-Assistive ROM
Muscle and Joints (Motions in Daily-Live) Application of PROm/AROM (Do Not Force Past Pain). Do NOT force past limit. Glide smooth motion, avoid resistance. In unilateral cases (the patient can move both sides but has 1 uninvolved with trauma) will need a patient will clear body lines. Starting Exercise Uncontrolled Cardiac.
