Mosso’s ergography by Pandian M
Ergography is the recording of an ergogram, which records the voluntary contractions of skeletal muscles during exercise on a moving paper. It is used to assess work done by flexing fingers and to study muscle fatigue. The subject contracts their fingers against resistance using an ergography device until fatigued. Various factors like weight lifted, contraction frequency, motivation, and blood supply to the exercising muscle can influence the degree and duration of work performed as well as the onset of fatigue. Fatigue results from the depletion of nutrients and accumulation of metabolites in the muscles.
Mosso's ergography
This document describes Mosso's ergography experiment to study human fatigue. The experiment uses Mosso's ergograph apparatus to measure the work done by lifting weights with the middle finger over time. Various factors are tested like increasing weight, venous occlusion, and arterial occlusion. Calculations are provided to determine work done in kg-meters and time to fatigue in minutes under different conditions. The results show fatigue occurs sooner with venous occlusion due to metabolite buildup and earliest with arterial occlusion due to lack of nutrients and oxygen to the muscle. The experiment demonstrates the physiological significance of factors affecting fatigue and work done.

Mosso's ergography (including Video description of instrument and procedure)
This document describes Mosso's ergography experiment to study human fatigue. The experiment uses Mosso's ergograph apparatus to measure the work done by voluntary contractions of the forearm muscles by lifting weights over time. It details the objective to define ergography, calculate work done, and study the effects of venous and arterial occlusion on fatigue onset. The procedure instructs setting up the apparatus and having subjects rhythmically lift weights while contractions are recorded until fatigue prevents further lifting. Calculations determine work done and fatigue time under normal circulation and with venous or arterial occlusion. The findings show occlusion decreases work and hastens fatigue by inhibiting nutrient delivery or waste removal from muscles.
Mean and Methods of Flexibility Development
This document discusses flexibility, which is the range of motion of joints. It describes different types of flexibility including general, specific, active, passive, static, and dynamic flexibility. It also discusses factors that determine flexibility such as anatomical structure, ligaments, muscle stretchability, coordination, and strength. Finally, it outlines several methods for developing flexibility, including ballistic, slow stretching, slow stretching and holding, post isometric stretch, and PNF stretching techniques.
Warm Up and Flexibility
This document discusses warm-up and stretching. It defines warm-up as activities that increase muscle temperature and blood flow, improving performance. An effective warm-up has general and sport-specific components lasting 5-12 minutes. Stretching is most effective post-exercise and should involve dynamic motions. Flexibility depends on factors like age, sex, activity level and can be improved through regular stretching, especially PNF techniques using partner assistance or agonist muscle contraction. Guidelines are provided for static, dynamic and PNF stretching techniques.

Neuromuscular adaptation to exercise –application to practise
This document discusses neuromuscular adaptations to exercise. It explains that neural adaptations occur within the nervous system at the motor cortex, spinal cord, and neuromuscular junction in response to training. Neuromuscular adaptations include increases in muscle size, strength, mitochondria, and glycogen storage. The type and intensity of exercise determines the specific adaptations, with strength training increasing fiber size and endurance training increasing aerobic capacity. Neural adaptations differ by changing central drive and motor unit properties within the nervous system. Overtraining can cause extreme fatigue, illness or injury from insufficient rest between training sessions.
Strength and the muscular system
This document discusses the muscular system and strength training. It explains that muscles work with connective tissues like tendons, and describes the series elastic component (SEC) and parallel elastic component (PEC) of the muscle model. The document also discusses the different types of muscle contractions (isometric, concentric, eccentric), muscle actions like agonist and antagonist muscles, and the importance of the nervous system in strength and muscle development. Functional strength training aims to improve abilities like speed and endurance, while structural training focuses more on muscle hypertrophy.
Chap01
This document provides an overview of the muscular, neuromuscular, cardiovascular, and respiratory systems. It describes the structure and function of skeletal muscle fibers and motor units. It explains the sliding filament theory of muscle contraction. It also describes the structure and function of the heart and blood vessels, the conduction system that controls heart rate, electrocardiograms, and blood composition. Finally, it outlines gas exchange that occurs in the lungs through the process of inspiration and expiration.

Therapeutic Exercises
Habitual physical activity provides numerous health benefits including improved cardiovascular function, reduced risk of heart disease and stroke, enhanced muscle function, increased bone density, weight management, and protection against diabetes. Therapeutic exercises include range of motion, resistance training, aerobic exercise, flexibility exercises, and techniques like proprioceptive neuromuscular facilitation to address specific medical conditions and injuries. Contraindications for exercise include certain cardiovascular conditions and acute illnesses.
Athlete Specific Strength Training Lecture
This is part of a series of lectures I gave at Wilmington College for the class, "Strength Programming for Sport".
Core and Flexibility
Core exercises target the abdominal, hip, and spinal muscles to improve stability and balance. Examples include crunches, reverse crunches, and Russian twists. Flexibility involves moving joints through their full range of motion while stretching moves beyond normal range. Static stretching slowly stretches muscles to their limit, like toe touches and lunges. Dynamic stretches use controlled swinging, like inchworms and leg swings. Proprioceptive neuromuscular facilitation (PNF) alternates stretching and contracting targeted muscles for advanced flexibility training and rehabilitation.
Chapter 8
The document discusses flexibility, stretching, and related topics. It defines flexibility and stretching, and addresses questions about whether stretching prevents injuries, how flexibility is affected by strength training, whether stretching can help with weight loss, how much stretching should hurt, problems caused by poor flexibility, benefits of good flexibility, and factors that affect flexibility like age, gender, and lifestyle. It also defines plastic and elastic elongation and the principles of flexibility prescription including mode, intensity, repetitions, and frequency of exercise.
Strength Exercises for Sport Performance
Lecture on strength training exercises that I gave as a lecture for Wilmington College students in HPE 345, Strength Programming for Sport. Taken from the text: Science and Practice of Strength Training, 2nd edition.
Plyometric
Plyometric training involves explosive exercises that use the stretch-shortening cycle of muscles to improve speed, strength, and power. It works by elastic energy being stored in tendons and muscles during eccentric contractions and released during subsequent concentric contractions. A proper plyometric program considers factors like exercise mode, intensity, frequency, volume, progression over time, and safety precautions. Short-term plyometric training of 2-3 sessions per week for 4-16 weeks can improve athletic performance measures like jump height, sprinting, and agility.
Mean, Methods and Development of Speed Training
This document discusses different aspects of speed in sports. It defines various types of speed, including reaction speed, movement speed, sprinting speed, locomotor speed, and speed endurance. For each type of speed, it provides an example of the relevant sport or movement and recommends exercises to improve that particular speed ability. Exercises focus on practicing movements at high intensity and short rest intervals to build explosive power and the ability to maintain speed over longer durations while fatigued. The overall goal is to execute motor actions and complete movements in the shortest possible time.
Lecture 5 task specific strength2_(pt2) ppt
This document discusses several key concepts related to strength training:
1) Eccentric force can exceed maximal isometric strength by 50-100%; the stretch shortening cycle (SSC) increases force and power when a muscle contracts immediately after being stretched.
2) The SSC relies on elastic energy stored in tendons during eccentric contractions. Proper conditioning is needed before high eccentric work to prevent damage.
3) Muscle spindles and Golgi tendon organs play roles in the SSC through reflexive muscle contractions and tension inhibition, respectively. Having more spindle than GTO response allows for greater SSC power.
4) Force production depends on factors like joint angle, muscle length, moment
Ed fisica
1) Warming up before exercise is important to gradually increase intensity and blood flow to prepare muscles and reduce injury risk. It should include general activities to raise body temperature followed by sport-specific movements.
2) Proper warm ups have many benefits like increased blood flow, oxygen delivery to muscles, and reduced muscle soreness. The goals are to avoid injury while performing at one's best.
3) Basketball rules include 4 quarters of 10 minutes, 5 players per team, and scoring points by shooting from inside or outside the 3-point line. Fouls and violations include traveling and double dribbles.
New Flexibility
Flexibility is defined as the range of motion around a joint that is influenced by bones, muscles, tendons, ligaments, and skin. Maintaining good flexibility can help prevent injuries by reducing muscle strain and backaches. There are different types of stretching, including static, ballistic, and proprioceptive neuromuscular facilitation (PNF). PNF stretching, which involves contracting and relaxing muscles through their range of motion, has been shown to be the most effective technique for improving flexibility. Guidelines for safe stretching include avoiding pain during stretches and contraindicated stretches for any medical conditions.
Therapeutic exercise - Physiotherapy
This document provides an overview of physiotherapy and rehabilitation techniques. It discusses the roles of a physiotherapist in examination, intervention, prevention, consultation, education and research. It then describes different types of therapeutic exercises including strength, mobility, balance, flexibility and coordination exercises. Various techniques for assessing and improving muscle strength, endurance, power, flexibility and movement are outlined.

Static vs dynamic
Static stretching involves holding a muscle in a stretched position to increase flexibility, while dynamic stretching uses controlled movements to stretch muscles before activity. The document compares the benefits and drawbacks of each type. Static stretching may improve flexibility long-term but negatively impact performance, while dynamic stretching enhances performance but its long-term effects are unclear. The best approach depends on factors like age, sport, injury history, and the specific muscles targeted.
strength PDHPE
There are three main types of resistance training: isometric, isotonic, and isokinetic. Isometric training involves contracting muscles without movement through static positions. Isotonic training uses weights and allows muscle movement through a range of motion with constant resistance. Isokinetic training uses machines to provide resistance equal to the force exerted through a full range of motion at a controlled speed. Each method has advantages like targeting specific muscles or joints and disadvantages such as limited range of motion or expensive equipment requirements.
Range of motion and muscle strengthening exercises
This document discusses range of motion and muscle strengthening exercises presented by Miss. Shweta Sharma. It describes isometric and isotonic exercises and their purposes, which include increasing muscle strength and endurance. A variety of exercises are presented targeting different parts of the body, along with benefits of physical activity for neurological conditions and patient education tips.
Warm up, Main activity and Cooldown 1ºESO Secciones
This document discusses the importance of warming up, cooling down, and the three main parts of a physical education session: warm up, main activity, and cooldown. It explains that warming up prepares the body for exercise by raising its temperature and heart rate, improves performance, and prevents injuries. A proper warm up includes cardiovascular exercise, static stretching, and joint mobility exercises. The main activity can vary depending on the sport or training goals. Cooling down gradually returns the body to its normal state and prevents muscle soreness. Not everyone needs to warm up in exactly the same way as the warm up should be tailored to factors like age, sport, fitness level, time of day, and temperature.

Shoulder Pathology and the Industrial Athlete
This document discusses common shoulder pathologies seen in industrial athletes. It begins with shoulder anatomy including bones and muscles. It then discusses common injuries like impingement and rotator cuff tears. Impingement is caused by encroachment in the subacromial space and can be primary from bone spurs or congenital issues, or secondary from muscle imbalances or poor posture. Rotator cuff tears can be partial or full thickness and result from repetitive stress or acute trauma. Treatment involves rehabilitation exercises and potentially surgery. Trigger points are also discussed as a potential cause of shoulder pain presenting in specific patterns that can be treated with massage or spray techniques. Overall the document provides an overview of shoulder issues in industrial settings and potential
Non surgical conditions of knee joint and its rehabilitation
This document provides information about non-surgical knee conditions and their rehabilitation. It discusses the anatomy of the knee joint, including ligaments, muscles, and menisci. Common knee conditions like osteoarthritis, knee effusion, ACL injuries, patellar tendonitis, and meniscal tears are described. The symptoms, causes, diagnosis, and treatment options for these conditions are summarized. Physical therapy plays an important role in the rehabilitation of knee issues through exercises, modalities, bracing, and education to reduce pain, improve function and mobility, and prevent further injury.
EXERCISE TESTING.pptx
Exercise testing involves monitoring a patient's heart rate, blood pressure, and electrocardiogram while undergoing controlled exercise, usually on a treadmill or stationary bike. It is used to evaluate cardiovascular function and identify any abnormalities in heart rhythm or blood flow. There are several standardized exercise protocols, the most common being the Bruce Protocol which increases the speed and incline of a treadmill every 3 minutes. Exercise testing can help diagnose chest pain, assess cardiac risk, and monitor the effects of treatment. Contraindications include recent heart attack or conditions that could make exercise unsafe. Complications can include changes in heart rhythm, blood pressure issues, or other cardiac or musculoskeletal problems.

The Integrated Spring-Mass Approach to Treating Thoracic Outlet Syndrome
Presented at the Florida Chiropractic Physicians Association Conference in Orlando Florida in 2015
by Dr James Stoxen DC, FSSEMM (hon)
If you have headaches, neck pain, upper back or shoulder pain, you may have thoracic outlet syndrome.
As a syndrome rather than a disease, TOS produces a variety of symptoms that suggest underlying causes, rather pointing directly to a specific ailment. These, atypical symptoms, are the result of persistent compression of nerves, arteries and veins traveling through the thoracic outlet and tunnel.
The thoracic outlet, inlet or compartment is a tunnel located under the shoulder and over the rib cage, where the artery, vein and nerves pass from the chest and neck area into the arm and hand.
It is one of the most underrated, overlooked and misdiagnosed conditions and proves difficult to manage. Medical professionals appreciate that it is probably the most important peripheral nerve compression in the upper extremity. (1)
Thoracic outlet syndrome (TOS) is a complicated disorder and generates great medical controversy.

EXERCISE PHYSILOGY I and II.pptx
1. The document discusses various physiological responses that occur during exercise, including cardiovascular, respiratory, and endocrine responses.
2. It describes how oxygen consumption increases during exercise to meet energy demands, but an oxygen deficit occurs initially until maximum oxygen consumption is reached.
3. The increased oxygen demands of exercise are met through both aerobic and anaerobic pathways, resulting in increased lactate production and an oxygen debt that must be repaid after exercise through additional oxygen consumption.
Lifetime Fitness: Ch 5
This chapter discusses flexibility, different types of stretching, and recommendations for an effective warm-up and cool-down routine. It defines flexibility and describes how it declines with age. There are three main types of stretching: static, ballistic, and PNF. Static stretching involves holding a stretch for an extended time and is best after a workout. Ballistic stretching uses bouncing motions and should be done before a workout. PNF stretching is the most effective but requires a partner. A dynamic warm-up should last 10-15 minutes and gradually increase intensity through movements like walking lunges and jumping jacks. Stretching should be included at the end of each workout for muscle recovery and improved flexibility.
Hip oa + itbs
Hip osteoarthritis is a degenerative joint disease that commonly affects the elderly. It causes progressive damage to articular cartilage and surrounding structures in the hip joint. The main symptoms are pain in the groin region that may radiate to the knee, joint stiffness, and functional impairment. Risk factors include age, obesity, previous hip injury or surgery. Diagnosis is based on clinical history, physical exam findings, and radiographic changes. Treatment involves patient education, exercises to increase strength and flexibility, weight loss, and joint replacement surgery for advanced cases.

It defines respiratory depression and lists several potential causes. It describes how alcohol can lead to pneumonia, acute respiratory distress syndrome, and other long-term respiratory issues over time. The document explains blood gas analysis and the effects of abnormal pH, PCO2, and HCO3 values. It also discusses rib fractures, pneumothorax, and their potential complications like respiratory failure. Treatment options are provided for rib fractures, pneumothorax, and the management of associated conditions.
Range Of Motion Assessment
Goniometry refers to the measurement of joint angles in the human body. It is an important part of a physical examination to determine range of motion, evaluate progress, and modify treatment. There are different types of goniometers used to measure motion in various planes at joints like the shoulder, elbow, wrist, fingers, hip, and spine. Factors like a person's age, joint health, surrounding soft tissues, and pathological conditions can impact the normal range of motion values. Proper positioning, stabilization, and identification of bony landmarks is required to accurately measure and document a joint's range of motion.

Thalamus .ppt
The thalamus is located in the center of the cerebral hemispheres. It receives sensory input from various areas and projects to different cortical regions. The thalamus and cortex work as a single functional unit, with the thalamus integrating inputs and the cortex performing higher-level processing.
Anatomically, the thalamus is divided into anterior, lateral, and medial groups of nuclei. The lateral group contains sensory relay nuclei that project to sensory cortices. Association nuclei in the medial and dorsal groups integrate sensory and limbic inputs and project to association cortices. Nonspecific nuclei in the intralaminar and midline regions are involved in arousal, emotions, and alertness.

THE COUNTERCURRENT.pptx
The countercurrent mechanism involves the loops of Henle and vasa recta working together to create and maintain an osmotic gradient in the renal medulla. The loops of Henle function as countercurrent multipliers, actively transporting ions from the thick ascending limb to increase the osmolarity of the interstitial fluid. The vasa recta parallel the loops of Henle and function as countercurrent exchangers, rapidly exchanging fluids between ascending and descending limbs to minimize washing out solutes and preserve the osmotic gradient as blood flows through the medulla. This countercurrent system allows urine to be concentrated as water is reabsorbed along the nephron according to the osmotic gradient in the

Blood is a connective tissue composed of plasma and cellular elements. Plasma is 55% of blood and contains water, proteins, nutrients, gases, and electrolytes. Cellular elements include red blood cells, white blood cells, and platelets. Red blood cells transport oxygen and carbon dioxide. White blood cells help fight infection. Platelets help with blood clotting. Blood has many functions including nutrient transport, waste removal, temperature regulation, hormone transport, and immune defense. Anemia is a decrease in red blood cells or hemoglobin and can be caused by blood loss, increased cell destruction, or decreased cell production.
Determination of WBC count by Dr. Pandian M..pptx
The document describes the calculation method for determining white blood cell (WBC) count per cubic millimeter of blood. It involves dividing a central square under the microscope into 25 smaller squares and counting the WBCs in 5 of those squares. This number is then used to calculate the number of WBCs in 1/50 cubic millimeter, and through multiplication, the number of WBCs per cubic millimeter of undiluted blood is determined based on the dilution used during sample preparation.
PLATELET COUNT by Dr. Pandian M .pptx
Dr. Pandian M describes the procedure for performing a platelet count. Platelets serve important hemostatic functions and their normal range is 1.5-4 lakhs/cumm. The procedure involves mixing blood with a diluting fluid in a Neubauer chamber, then counting platelets in grid squares under a microscope. For the sample, 40 platelets were counted in 1/50 mm3, indicating a platelet count of 2 lakhs/mm3 of blood, within the normal range. Abnormally high or low platelet counts can occur due to various bone marrow and other disorders.

Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) Cosmetics
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.

Storyboard on Skin- Innovative Learning (M-pharm) 2nd sem. (Cosmetics)
Skin is the largest organ of the human body, serving crucial functions that include protection, sensation, regulation, and synthesis. Structurally, it consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous layer).
1. **Epidermis**: The outermost layer primarily composed of epithelial cells called keratinocytes. It provides a protective barrier against environmental factors, pathogens, and UV radiation.
2. **Dermis**: Located beneath the epidermis, the dermis contains connective tissue, blood vessels, hair follicles, and sweat glands. It plays a vital role in supporting and nourishing the epidermis, regulating body temperature, and housing sensory receptors for touch, pressure, temperature, and pain.
3. **Hypodermis**: Also known as the subcutaneous layer, it consists of fat and connective tissue that anchors the skin to underlying structures like muscles and bones. It provides insulation, cushioning, and energy storage.
Skin performs essential functions such as regulating body temperature through sweat production and blood flow control, synthesizing vitamin D when exposed to sunlight, and serving as a sensory interface with the external environment.
Maintaining skin health is crucial for overall well-being, involving proper hygiene, hydration, protection from sun exposure, and avoiding harmful substances. Skin conditions and diseases range from minor irritations to chronic disorders, emphasizing the importance of regular care and medical attention when needed.
