Study Notes

Research

Evidence-Based Practices: Clinical decisions based on best available research, fostering critical thinking, problem-solving, and informed decision-making. Application optimizes clinical practice and builds professional experience. Three best methods for whom, why, and what are key considerations.
Body of Evidence: Accumulated facts in a specific area, developed through scientific inquiry and systemic evaluation, requiring time.
Facts vs. Evidence: Science provides reliable knowledge. Assessing evidence, cumulatively, yields accurate, trustworthy evidence.
Experimental vs. Non-Experimental Research:
- Experimental: Manipulating independent variables (what's changed) and observing effects on dependent variables (the outcome), with control groups.
- Non-Experimental: Observing variables naturally, without manipulation. Difficult to determine causation.
Qualitative vs. Quantitative:
- Quantitative: Numerical data (objective).
- Qualitative: Observable or categorical data (subjective).
- Basic: New knowledge, foundational information.
- Applied: Builds upon basic research, using meta-analysis to address real-life problems.
Observational vs. Intervention:
- Observational: Watching participants without influencing them.
- Intervention: Applying treatments to observe their effects.
Cross-Sectional vs. Longitudinal Design:
- Cross-Sectional: A short snapshot at a single point in time.
- Longitudinal: Observations over a long period.
Repeated Measures Design: Measuring variables repeatedly on the same participants over time.
Validity, Reliability, and Hypothesis:
- Validity: Measures what it's intended to measure.
- Reliability: Produces consistent results.
- Hypothesis: A prediction of the study's outcome.
Independent/Dependent Variables:
- Independent Variable: Manipulated by the researcher.
- Dependent Variable: The outcome measured by the researcher.
Bias: Prejudice towards a specific result.
Primary Source Research Articles:
- Sections: Abstract, Introduction, Methods, Results, Discussion, Conclusions, and References.
- Types: Original research articles, review articles, and meta-analyses (numerical summaries of research trends).
Secondary Source Research Articles:
- Types: Textbooks (educational summaries), professional books (comprehensive expert works), and review articles (narrative reviews); meta-analyses (require background in statistics). Sources range from popular magazines and websites to peer-reviewed journals.
Epidemiology: Study of factors related to specific behaviors in relation to disease or injury.
Cross-Sectional Surveys: Measure risk factors and disease presence/absence simultaneously. Don't show cause and effect, but can generate useful data.
Randomized Control Trials: The gold standard for medical research, allowing researchers maximum control and random assignment to experimental and control groups.
Framingham Heart Study: Longitudinal study tracking risk factors and disease incidence. Expensive and time-consuming but reveals risk profiles before outcomes, change in risk factors over time, and absolute risk estimates.
Observational Studies:
- Cohort: Comparing exposed and non-exposed groups (e.g., factory workers).
- Case-Control: Comparing individuals with and without a disease to identify potential causes.
- Prospective Cohort Studies: Following a randomly selected group over time to study disease incidence.
Incidence Rates: Frequency of events over a specific time, divided by the population at risk.

Nutrition

Nutrition's Impact: Fertility, fetal development, health, environment, body composition, and performance.
Artificial Ingredients: Highly processed foods often contain numerous artificial ingredients with limited nutritional value.
Mechanical Processing: Does not directly affect the healthfulness of food (e.g., freezing, grinding, heating, pasteurization). Only if it does not add chemicals.
Missing Nutrients in Ultra-Processed Foods: Healthful plant compounds (antioxidants, anti-inflammatory, anticarcinogenic).
Dietary Fiber Benefits: Slows carbohydrate absorption, promotes satiety, and acts as a prebiotic.
Ultra-Processed Foods (Dr. Nestle's Definition): Foods that cannot be made at home.
Science of Nutrition in Medicine: Often ignored in medical schools and not reimbursable by insurance.
Public's Nutrition Adherence: Confusion, convenience, and how healthy foods are prepared.
Plant-Based Diet and Heart Disease: Can substantially lower heart disease risk.
WHO and Meat as a Carcinogen: Meat contains heme iron that might contribute to carcinogen production and cell damage, related to cancer.
Animal Protein "Poor Package": Removes many beneficial plant compounds (fiber, antioxidants), concentrates contaminants, and adds inflammatory components.
Reduced Dairy Consumption Reasons: Impact on immune function, increased male estrogen, and potentially decreased testosterone.
Meat Ingestion on Blood and Performance: Increases inflammation by about 70%, impairs blood flow, potentially affecting heart disease and cancer risk with a significant impact on blood health.
Plant Protein Superiority: Rich in fiber, antioxidants, and phytochemicals. Improves blood flow and reduces inflammation.
Plant Proteins as Complete: All plants contain essential amino acids, though varying amounts. The quality is not inferior, and the body utilizes individual amino acids to build necessary proteins.
Meat and Dairy's Hormone Effects: Animal products can increase estrogen levels, impacting hormone balance.
Animal Agriculture's Environmental Impact: Contributes significantly to greenhouse gas emissions, deforestation, species extinction, ocean dead zones, and freshwater consumption. Also, produces contaminated waste.
Ag Gag Laws, Cheeseburger Law, Common Sense Consumer Act: Laws and acts relating to consumer awareness of diet/nutrition issues.
Environmental Impact of Big Pharma: Pharmaceuticals are found in water supplies across the United States.

Sport Psychology

Mindset Matters (Placebo Effect and Maid Study): Study demonstrating the power of mental state on physical outcomes.
Sport/Exercise Psychology: The scientific study of people in sports/exercise and the application of knowledge.
ABCs of Psychology: Affect (feelings), Behavior (actions), and Cognitions (thoughts).
Sport/Exercise Psychology Objectives: Understand the impact of psychology on performance and the impact of activity on well-being.
Certified Mental Performance Consultant vs. Clinical/Counseling Sport Psychologist: Different levels of training and licensure related to treating disorders.
Sport/Exercise Psychologist Roles: Research, teaching, and consulting.

Risk-Benefit Exercise Prescription

Physical Activity Continuum: Progression from sedentary to peak performance.
Five Components of Fitness: Aerobic, muscular strength, muscular endurance, flexibility/functional movement, and body composition.
Skilled-Based Components: Power, balance/coordination, reaction time, agility, and speed.
Common Injuries: Lumbar muscle strains, ankle sprains, bone fractures dominate, with ankles and knees featuring highest incidence. Injuries also frequently occur during practices.
Modifiable Injury Risks: Most injury risks are modifiable.
Female Athlete Injuries: Potential factors include less training and lifting experience, and foundational limitations impacting skills.
Physiological Factors in Exercise Prescription: To improve health and performance.
Risk-Reward Considerations: Comparing the benefit of an exercise against the potential risk of injury. Pre-existing conditions, body systems, and appropriate fluid periodization of training load considerations.
Keys to Safe Training: Evaluating joint mobility, and appropriate aerobic and anaerobic training.
Core Utilization Biomechanics: Stabilizing spine, and avoiding excessive joint angles
Hip Thrusters Risks: Hyperextension risks, impingement and wear-and-tear on the hip labrum.
High vs. Low Risk Exercises: High-risk moves take joints outside their natural range or add significant resistance without foundational, prior capability.
