30ENERGY SYSTEMS ATP-CP / PHOSPHAGEN SYSTEM (Anaerobic Alactic) ANAEROBIC GLYCOLYSIS (Anaerobic Lactic)AEROBIC GLYCOLYSISFATTY ACID OXIDATION / OXIDATIVE PHOSPHORYLATIONCells require energy for active transport, synthesis, impulse conduction (nerve cells), contraction (muscle cells), and so on. Cells must be able to 'capture' and store energy & release that energy in appropriate amounts when needed. An important source of energy for cells is glucose (C6 H12O6):C6H12O6 + O > CO2 + H2O + ENERGYHowever, this reaction releases huge amounts of energy (for a cell). So, cells gradually break down glucose in a whole series of reactions & use the smaller amounts of energy released in these reactions to produce ATP (Adenosine Triphosphate) from ADP (Adenosine Diphosphate).
31ATP-CP SYSTEM ANAEROBIC GLYCOLYSIS ATP, adenosine triphosphate (there are three phosphates in ATP), is not stored to a great degree in cells. Once muscle contraction starts the regeneration of ATP must occur rapidly. There are three primary sources of ATP which, in order of their utilization, are creatine phosphate (CP), anaerobic glycolysis, and oxidative phosphorylation.Energy from ATP derives from cleaving of the terminal phosphate of the ATP molecule. The resulting molecule is called ADP, adenosine diphosphate. Creatine phosphate converts ADP back to ATP by donating its phosphate in the presence of an enzyme which is called either creatine kinase (CK) or creatine phosphokinase (CPK). The reaction of CP with ADP to form ATP is very rapid but short lived, since the cell does not store high amounts of CP. However during short, high intensity contractions, CP serves as the major source of energy. This form of energy generation is often called alactic anaerobic because it neither produces lactate nor requires oxygen. It is of paramount importance in sports requiring bursts of speed or power such as sprints of 10 seconds or less in duration.As soon as muscle contraction starts, the process of anaerobic glycolysis also begins. Anaerobic glycolysis does not contribute as large an amount of energy as CP in the short term, but its contribution is likely to last from 30 to 60 seconds. During glycolysis, locally stored muscle glycogen and possibly some blood born glucose, supply the substrate for energy generation. No oxygen is required so the process is called anaerobic. Lactic acid (lactate is the salt) is formed as the end product of pure anaerobic glycolysis. Sufficient lactic acid formation can lower the pH of the cell to the extent that metabolism is turned off in the cell. The major substrate for anaerobic glycolysis is glycogen, so prior hard exercise without adequate repletion of glycogen is going to limit further high intensity, short term work by muscles.
32ANAEROBIC VS. AEEROBIC GLYCOLYSIS In glycolysis, the six-carbon sugar glucose is oxidized and split in two halves, to create two molecules of pyruvate (3 carbons each) from each molecule of glucose. Along the way, the cell extracts a relatively small amount of energy from glucose in the form of ATP, 2 ATP molecules collected for each glucose molecule that starts down the glycolytic path. The pyruvate produced has one of three metabolic fates, to either become acetyl-CoA, ethanol, or lactate. When oxygen is available, the pyruvate can be converted to acetyl-CoA and enter the Krebs Cycle, where the acetyl-CoA will be completely oxidized and generate ATP through oxidative phosphorylation.There are ten enzymes that catalyze the steps in glycolysis that convert glucose into pyruvate, and the entire pathway is located in the cytoplasm of eukaryotic cells. The activity of the pathway is regulated at key steps to ensure that glucose consumption and energy production match the needs of the cell.
33FATTY ACID OXIDATIONThe final, and virtually limitless supply of energy, comes from the process of oxidative phosphorylation. Maximum energy production rates from oxidative phosphorylation are not as high as from glycolysis. Aerobic events like the marathon are run at a considerably slower pace than a 440 because of this fact. The substrates for oxidative metabolism are primarily glucose and fat (free fatty acids, not cholesterol), although protein can also act as an energy source through intermediate conversions to glucose, glucose precursors or free fatty acids. Because fat can be metabolized aerobically, most well nourished humans have a near limitless supply of energy for low intensity exercise. Limitation of low intensity exercise is rarely due to substrate depletion, although depletion of muscle glycogen may also result in fatigue during aerobic events. The reasons for this are beyond the scope of this description.
35ENERGY OUTPUT vs. TIME/DURATION (5-10sec)(1-3min)(20min+)Based on world record times, humans can maintain maximum sprinting speed for approximately 200 m. The average speeds for the 100 m and 200 m world records are similar (21.6 mph and 22.4 mph, respectively). However, with increasing distances, average speeds decline. The average speed for the marathon world record is 12.1 mph, which is 55% of the world record sprinting speed. This is remarkable since the marathon is more than 200 times the length of a 200 m race. Although natural selection plays a crucial role in elite sprinting and marathon performance, the energy systems also must be highly trained and exercise-specific to be successful. For example, the energy needed to maintain an average sprinting speed of 22 mph for 200 m or less and an average running speed of 12.1 mph for the marathon are acquired by two very different systems (the predominant energy systems required for running at different speeds are shown in the first figure). The primary energy source for sprinting distances up to 400 m is PCr. From 400 m to 1,500 m, anaerobic glycolysis is the primary energy source. For distances longer than 1,500 m, athletes rely primarily on aerobic metabolism.The rate of glycogen and fat utilization will vary according to the relative running speed. Although the rate of glycogen utilization is low while running a marathon, the duration of the event increases the possibility of depleting glycogen stores. In contrast, the rate of glycogen utilization is substantially higher during a 5,000 m run, but glycogen depletion is not a concern because of the short duration of the event.Maximum maintainable speed drops by approximately 7 mph as running distance increases from 200 m to 1500 m (about 1 mile). However, as the distance increases from 1 mile to 26 miles, maximum maintainable speed only drops an additional 3.5 mph. On average, a healthy, fit, non-elite, male athlete can be expected to sprint at an average speed of mph for m and approximately 6-8 mph for a marathon.
36CLASSIFICATION OF PHYSICAL ACTIVITIES BASED ON ENERGY SYSTEMS (Essentials of Exercise Physiology. McArdle, Katch & Katch. 1994)
38O.F.I.T.T. Objective: Based on S.M.A.R.T. Goals Frequency: Affected by Intensity & DurationIntensity: Dictates specific physiologic & metabolic changesTime: Duration which intensity level is maintained; Duration & Intensity inversely related (“You can train hard or you can train long, but you can’t do both”)Type: Exercise/Equipment selection
39O.F.I.T.T. General Guidelines for CV Training Objective?Frequency?Intensity?Time?Type?Improve or maintain the level of efficiency to deliver O2 and remove CO2; aerobic and/or anaerobic trainingAt least 3x/week with 24-48hrs rest between sessionsDependent upon energy system to be trained for client’s goalsDependent upon intensity level prescribed; lower intensity conducted over longer time period (i.e. 30min +) can be accumulated intermittently or continuouslyContinuous vs. Discontinuous Training (i.e. Intervals); Both Aerobic & Anaerobic Systems must be trained
40Improvement & Maintenance PARTNER EXERCISE: Using the case study assigned to you from the back of the manual determine 1) your client’s S.M.A.R.T. Goals, and 2) apply the O.F.I.T.T. principle to design their CV program. Be prepared to share with the rest of the class.Improvement & Maintenance1. What is the minimum FREQUENCY, INTENSITY and DURATION/TIME required to maintain aerobic fitness (the central factors)?2. What is the minimum FREQUENCY, INTENSITY, DURATION/TIME and EFFORT INTERVALS required to maintain anaerobic fitness (the peripheral factors)?
41Specific Guidelines for ATP-CP System Objective: Enhance muscle’s ATP-CP energy capacity5-10 second max output bursts followed by sec active recovery; Alternate between 2+ work intervals and 2+ recovery intervalsAdaptation occurs within 2-4 weeks. Detraining will take effect within 2 weeks.Note: high risk training; potential injuries associated with this type of training.Especially important to warm up and cool down.Benefits = sprinters/events lasting less than 20 sec.
42Specific Guidelines for Glycolytic System Objective: Elevate Lactate Threshold LevelsSub max levels of intensity will not stimulate adaptation. Need to train at level that will elicit lactic acid production.Train 2-3x/week (ample time for recovery); 2-3 min effort intervals followed by 2-3 min recovery intervals; repeat 2-12x2-3 min recovery is not enough time to deplete lactic acid from blood, therefore lactate threshold must elevate to accommodate the training stimulus.Note: complete LT training at least 2 weeks before competitionBenefits: Everyone, but the highest injury rate.
43Specific Guidelines for Oxidative System Objective: Improve body’s ability to deliver O2 and remove CO2 through central factorsSub-maximal training; 60-80% MHR, 20min +Not necessarily “sport specific”Most benefits are central adaptations involving the heart circulatory and respiratory systems.Note: the most appropriate introductory cardiovascular program to start with to build a good fitness base.

51MUSCLE MACRO & MICRO STRUCTURES Muscles have both electrical and chemical activity. There is an electrical gradient across the muscle cell membrane: the outside is more positive than the inside. Stimulus causes an instantaneous reversal of this polarity, causing the muscle to contract (the mechanical characteristic) producing a twitch or movement.Muscle fibers are multinucleated, with the nuclei located just under the plasma membrane. Most of the cell is occupied by striated, thread-like myofibrils. Within each myofibril there are dense Z lines. A sarcomere (or muscle functional unit) extends from Z line to Z line. Each sarcomere has thick and thin filaments. The thick filaments are made of myosin and occupy the center of each sarcomere. Thin filaments are made of actin and anchor to the Z line.
52MUSCLE CONTRACTIONMyosin heads attach to binding sites on the actin filaments. The myosin heads swivel toward the center of the sarcomere, detach and then reattach to the nearest active site of the actin filament. Each cycle of attachment, swiveling, and detachment shortens the sarcomere 1%. Hundreds of such cycles occur each second during muscle contraction.ATP binds to the cross bridges between myosin heads and actin filaments. The release of energy powers the swiveling of the myosin head.
53MUSCLE CONTRACTION The Sliding Filament Theory Action Potential Myosin Binding to ActinThe Power Stroke
54TYPES OF MUSCLE ACTIONS ISOMETRIC: Muscle contracts with no change in its length during force production.CONCENTRIC: Positive muscle action whereby the muscle is shortened under its own force.ECCENTRIC: Negative muscle action whereby the muscle resists while it is forced to lengthen.During which type of contractions can you lift a) the most weight, and b) the least amount of weight?
55MOTOR UNITS 1. All-or-None Principle 2. Force of muscle contraction is dependent upon:a) Rate of motor neuron firingb) Number & Size of muscle fibres innervated
56PERIODIZATION OF REPS AND EXERCISES MOTOR UNITSPERIODIZATION OF REPS AND EXERCISES
57SENSORY MECHANISMS Muscle Spindle Golgi Tendon Organ Monitors changes in muscle length. When spindle fibers are rapidly stretched, a stretch reflex is elicited, causing muscle to contract.Golgi Tendon OrganMonitors changes in muscle tension. When tension developed in muscle becomes too great, further contraction is inhibited, and muscle relaxes.

65RESISTANCE TRAINING TERMINOLOGY ISOKINETIC CONTRACTION: Muscle action through a constant speed causing the muscle to exert a continuous and maximum force throughout a given ROM.DYNAMIC CONSTANT CONTRACTION (ISOTONIC): Muscle action against a constant resistance.DYNAMIC VARIABLE CONTRACTION: Muscle action against a changing resistance.REPETITION: A single, complete action of any one given exercise beginning from starting position, progressing to its ending position, and returning to its starting position.SETS: A given number of complete and continuous repetitions performed consecutively without resting.REP RANGE: Includes both a lower limit (least # of reps to be completed) as well as an upper limit (most # of reps to be completed).LOAD: The amount of resistance against which a muscular force is being applied.REPETITION MAXIMUM: Maximum load that can be lifted during an exercise in an all-out effort over a given number of reps.
66RESISTANCE TRAINING TERMINOLOGY CIRCUIT TRAINING ROUTINE: Several different exercises are completed, one immediately after another, within the resistance training session.REGULAR RESISTANCE TRAINING ROUTINE: Concentrating on one exercise at a time, multiple sets are completed for each exercise included within the resistance training sessionSTANDARD RESISTANCE TRAINING ROUTINE: For any one given exercise included within a regular resistance training session, the resistance, reps, and rest between sets remains constant.VARIABLE RESISTANCE TRAINING ROUTINE: For any one given exercise included within a regular resistance training session, the resistance, reps and/or rest between sets vary.SMALL GROUP EXERCISE: Design a “Standard Resistance Training Routine” and a “Variable Resistance Training Routine” for a muscle group of your choice.
67FUNDAMENTAL PRINCIPLES OF TRAINING Progressive Resistance(The Double Progression System of Resistance Training)Start with a conservative weight and reps consistent with the lower limit of the appropriate rep range.With each successive resistance training session, increase reps by at least one at a time: Lower Limit +1, Lower Limit +2,…Upper LimitWhen the upper limit of the rep range is completed with the initial weight, increase the intensity one level and drop the reps to the lower limit of the identified rep rangeComplete the rep progression with the new weight.PARTNER EXERCISE: Demonstrate the application of Progressive Resistance by performing 3 sets (10-15 reps/set) of an exercise (i.e. push-ups, lateral raises, bicep curls, etc.) and record the reps for each set.

72Improvement & Maintenance of Resistance Training Objectives PARTNER EXERCISE1. Your client has hit a plateau in their training program. Provide examples of 3 strategies you could apply to help stimulate new progress.2. Your work schedule and family commitments are interfering with your personal fitness program. How can you adjust your training frequency, intensity, sets, reps and exercises to maintain your muscular fitness?
73Over-training Risk of resistance over-training is associated with: Indicated by a plateau or drop in performance over a period of several days; caused by too little recovery time between sessionsRisk of resistance over-training is associated with:Failure to schedule adequate rest between similar training sessionsFailure to schedule “active rest” periods within micro-cyclesFailure to schedule “active rest” periods within meso-cyclesFailure to vary exercise intensitiesIncrease in the number of sets per exercise beyond 4Increase in the number of exercises for a given muscle groupFailure to vary exercises for a given muscle group

75ANATOMY (Upper Body) & PROGRAM DESIGN FOR MUSCULAR FITNESS LEARNING OBJECTIVESTo know the origin, insertion and line of action for the muscles of the upper body.To apply knowledge of anatomy to effective exercises and be able to distinguish between the agonists, antagonists, synergists and stabilizers.To apply an understanding of the advantages and disadvantages of compound versus isolation exercises in the design of resistance training programs.To understand the application of general strength training guidelines in the design of programs.To apply an understanding of a variety of specific resistance training principles commonly used in the design of programs.
76MUSCLE ORIGIN, INSERTION & ACTION ORIGIN: muscle attachment that moves least, generally more proximal (towards mid-line of body).INSERTION: muscle attachment that moves most, generally more distal (away from mid-line of body).LINE OF ACTION: An imaginary line that connects the origin to insertion and denotes the joint action(s) caused by the muscle.

Inability to smoothly abduct the arm against resistance may indicate a rotator cuff injury. Avoiding full ROM (i.e. not initiating deltoid exercises from fully adducted position) may not allow Supraspinatus to be fully strengthened since it is more fully activated at these initial degrees of shoulder abduction/flexion. Once injured ROM is typically restricted on the shoulder press.Examples of affected exercises: Shoulder Press, Upright Row, Lateral RaiseExample preventative / corrective exercises: Front Lateral Raise, Lying Lateral Raise

Medial Head2. Lateral HeadIn moderate force, soleus is preferentially activated in the concentric phase, whereas gastrocnemius is preferentially activated in the eccentric phase. Gastrocnemius becomes even more activated at higher lengthening velocities. During hopping, the gastrocnemius, with its greater proportion of FT motor units, is preferentially activated over soleus. During stationary cycling, gastrocnemius is also preferentially activated at higher pedaling speeds.Although involvement of the lateral and medial heads would not seem to be altered by medial or lateral rotation of the hip, MRI research suggests "toes in" activates both heads and "toes out" activates medial head to a higher degree.

122BIOMECHANICS & PRINCIPLES OF MOVEMENT LEARNING OBJECTIVESTo understand the application of Newton’s laws of motion (i.e. inertia, acceleration, reaction) in exercise performance.To understand force production relative to muscle length and position of muscle attachment.To understand the factors which influence efficiency of movement.To understand lever lengths relative to rotation and force production.
123The Essentials of Biomechanical Concepts Motion Analysis(movement pattern/muscle sequence, forces, lever arms, acceleration)Force (magnitude, direction, internal, external)TorqueLeversStability
124Movements occur in one of three planes of motion. PARTNER EXERCISE: Determine the plane of movement for each of the exercises in Chapter 5.
125A lever is a rigid bar that rotates about an axis. LEVERSA lever is a rigid bar that rotates about an axis.Rotation is caused as force is applied to the lever.Two types of force act upon human levers, they are:Muscular forceResistive force
126The Lever Fulcrum is the pivot point of a lever (joint). Lever Arm is the segment of the body (arm or leg) which is being moved about the fulcrum.Moment Arm is the perpendicular distance from the applied force to the fulcrum.Class Class Class 3
128Torque = F (rotational) x D (moment arm or force arm) Is the degree to which a force tends to rotate a lever about a fulcrum.Torque = F (rotational) x D (moment arm or force arm)PARTNER EXERCISE:1. Rank the following exercises in order according to which one produces the least amount of torque about the spine to the greatest.BB SquatBB Front SquatGood MorningsStiff-Legged Deadlift2. In what ways could proper technique reduce torque about the spine when squatting?
129FORCE APPLICATIONSGROUP EXERCISE: Provide an example for each of the following where the force either a) contributes to the intention of the exercise/movement, or b) works against the intention of the exercise/movement.Static FrictionKinetic FrictionElastic ForceAir ResistanceWater Resistance
130FORCE VECTORSPARTNER EXERCISE: Based upon the magnitude and direction of forces acting through the knee joint, rank the following versions of the lunge from the least stressful to the most stressful on the knees.Reverse LungeForward LungeStationary Lunge
131INTERNAL FORCES BIOMECHANICAL FACTORS AFFECTING MUSCLE FORCE Length of Muscle (Optimal = 1.2x resting length)Velocity of Muscle Contraction- Concentrically: force decreases as velocity increases- Eccentrically: force increases as velocity increases3. Tendon Insertion4. Changing Joint Angle
132INCREASING FORCE GENERATION PARTNER EXERCISE: Choosing one body part, provide a specific exercise example for manipulating each of the following factors in order to increase force generation in the muscle:Stabilizing body segmentsIncreasing the range of motion of a particular exerciseVarying the speed of muscular contractionUtilizing sequential movementIncreasing distance force is applied in selection of an exerciseUsing strongest muscles available for a taskUsing all the muscles that can contribute to a taskPre-stretching a muscle just prior to contractionPre-loading the muscle prior to the task
134LAW OF INERTIAA body at rest will remain at rest, and a body in motion will remain in motion unless acted upon by an external, unbalanced force.GROUP EXERCISEExplain the application of this law in the:Performance of a sport/activityProper execution of an exerciseDesign of PRT programs for Power
135LAW OF ACCELERATIONAcceleration of an object is directly proportional to the force acting on it, and inversely proportional to the mass of the object. (a = F/m)GROUP EXERCISE - Explain the application of this law in the:Use of medicine ball exercisesDesign of PRT programs for Power (%RM, # of reps, rep speed)
136LAW of ACTION-REACTION For every action there is an equal and opposite reaction."For every action, there is an equal and opposite reaction."The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.In the top picture (below), a physics student is pulling upon a rope which is attached to a wall. In the bottom picture, the physics student is pulling upon a rope which is attatched to an elephant. In each case, the force scale reads 500 Newtons. The physics student is pulling with 500 N of force in each case. The rope transmits the force from the physics student to the wall (or to the elephant) and vice versa. Since the force of the student pulling on the wall and the wall pulling on the student are action-reaction force pairs, they must have equal magnitudes. Inanimate objects such as walls can push and pull.The baseball forces the bat to the leftt (an action); the bat forces the ball to the right (the reaction). Note that the nouns in the sentence describing the action force switch places when describing the reaction force.IDENTIFY THE ACTION/REACTION FORCES IN THE BOTTOM PHOTO:The elephant's feet push backward on the ground; the ground pushes forward on its feet. The right end of the right rope pulls leftward on the elephant's body; its body pulls rightward on the right end of the right rope. The left end of the right rope pulls rightward on the man; the man pulls leftward on the left end of the right rope. The right end of the left rope pulls leftward on the man; the man pulls rightward on the right end of the left rope. The tractor pulls leftward on the right end of the left rope; the left end of the left rope pulls rightward on the tractor. etc., etc.GROUP EXERCISE - Explain the application of this law in the use of:Exercise TubingIsokinetic Exercise Equipment (i.e. Hydraulics, Computerized Cybex)Isometric Contractions
137StabilityRefers to the condition of balance where the weight of an object (centre of gravity) is aligned perpendicularly over it’s base of supports.Stability is essential for proper execution of all exercises.
138Factors Affecting Stability 1. CENTRE OF GRAVITYa) Location (more stability when COG closer to centre of base of support)b) Height (more stability when COG is lowered)c) Force Application (more stability when force received close to COG)2. BASE OF SUPPORTa) Size of BOS (wide vs. narrow)b) Contact Areac) Number of Supportsd) FrictionGROUP EXERCISE: Referring to exercises using the stability ball, give examples of how the Factors Affecting Stability affect performance of the exercise.3. MASSa) Magnitudeb) Distribution
139MOTION ANALYSISPARTNER EXERCISE: Considering the amount of force exerted in relation to the amount of resistance present, and the direction of the applied force in relation to the direction of the resistance, determine the benefit-to-risk ratio (high vs. low) for the following examples:DB Lateral Raise performed with arms straight vs. arms bent at 90 degreesLoaded vs. Unloaded hip flexion while standingLying straight leg raises with a) no added resistance, b) added resistance, and c) actively applied acceleration
