Question 1Functional anatomy and exercise physiology
In Sporttheorie, what is the immediate energy currency that must be resynthesized for continued muscle contraction?
- ATP (adenosine triphosphate) Correct answer.
- Only dietary fat stored in adipose tissue
- Atmospheric nitrogen dissolved in blood
- Bone calcium crystals
Explanation
Muscle contraction depends on splitting ATP into ADP and inorganic phosphate. Training theory emphasizes ATP resynthesis via phosphagen, glycolytic, and oxidative pathways according to load duration and intensity.
Question 2Functional anatomy and exercise physiology
Which energy pathway dominates a maximal ~100 m sprint lasting under about 10–15 seconds?
- Phosphagen (ATP–PCr) system with anaerobic alactic contribution Correct answer.
- Exclusive long-duration fat oxidation only
- Protein oxidation as the primary fuel
- Aerobic carbohydrate oxidation alone without anaerobic contribution
Explanation
Short maximal sprints rely primarily on stored ATP and phosphocreatine (anaerobic alactic). Glycolysis and aerobic pathways contribute more as duration increases.
Question 3Functional anatomy and exercise physiology
Which muscle contraction type involves force production without changing muscle length?
- Isometric contraction Correct answer.
- Concentric contraction
- Eccentric contraction only
- Ballistic shortening only
Explanation
Isometric (static) contractions produce force while length stays roughly constant (e.g., holding a plank). Concentric shortens; eccentric lengthens under load.
Question 4Functional anatomy and exercise physiology
What is the primary role of hemoglobin in exercise physiology?
- Transporting oxygen in the blood to working tissues Correct answer.
- Storing glycogen in muscle cells
- Acting as the main contractile protein in sarcomeres
- Lubricating joint cartilage
Explanation
Hemoglobin in red blood cells binds oxygen and delivers it to tissues. Endurance adaptations often include improved oxygen transport capacity.
Question 5Functional anatomy and exercise physiology
Stroke volume in cardiorespiratory physiology refers to…
- The volume of blood ejected by the left ventricle per beat Correct answer.
- The number of breaths per minute only
- The length of a swimming stroke in meters only
- Blood viscosity measured in bone marrow
Explanation
Stroke volume (Schlagvolumen) is blood ejected per heartbeat. Together with heart rate it determines cardiac output.
Question 6Functional anatomy and exercise physiology
Cardiac output equals…
- Heart rate × stroke volume Correct answer.
- Tidal volume × bone length
- Only resting blood pressure
- Muscle fiber count × shoe size
Explanation
Cardiac output (Herzzeitvolumen) = HR × SV. Endurance training often raises stroke volume and can lower resting HR.
Question 7Functional anatomy and exercise physiology
Which adaptation is typical of well-designed aerobic endurance training?
- Increased stroke volume and improved oxidative capacity of trained muscle Correct answer.
- Immediate conversion of all fast fibers to bone
- Permanent loss of mitochondria
- Elimination of red blood cells
Explanation
Endurance training commonly raises stroke volume, capillary density, and mitochondrial enzymes-supporting oxygen delivery and use.
Question 8Functional anatomy and exercise physiology
Eccentric muscle action is especially important because it…
- Controls lowering/deceleration under load and can produce high forces with relatively lower metabolic cost than concentric work at similar loads Correct answer.
- Means the muscle is offline
- Only occurs in zero-gravity
- Cannot cause delayed soreness ever
Explanation
Eccentric work lengthens under tension (landing, lowering). It is key in technique and injury-context discussions and can induce DOMS if novel or excessive.
Question 9Functional anatomy and exercise physiology
Oxygen deficit at the start of intense exercise occurs because…
- Oxygen uptake rises with a delay while ATP demand is already high, so anaerobic pathways cover the gap Correct answer.
- The lungs stop working permanently
- Hemoglobin refuses oxygen forever
- Only fat can be used in the first second
Explanation
At onset, VO2 kinetics lag behind demand; phosphagen and glycolytic pathways bridge the deficit. After exercise, excess post-exercise oxygen consumption helps restore homeostasis.
Question 10Functional anatomy and exercise physiology
Which statement about fiber types is most appropriate for Sporttheorie level?
- Type II fibers generally support faster, more forceful contractions and fatigue sooner than Type I oxidative fibers Correct answer.
- All fibers are identical in every human
- Type I fibers are only for 1-second maximal lifts
- Fiber type cannot influence training responses
Explanation
Type I: more oxidative, fatigue-resistant; Type II: faster/fatigable profiles (with subtypes). Distributions influence sport strengths but training still matters.
Question 11Functional anatomy and exercise physiology
Ventilation increases during exercise primarily to…
- Raise oxygen delivery and CO2 removal matching metabolic demand Correct answer.
- Cool the brain by stopping blood flow
- Store oxygen in tendons
- Eliminate the need for hemoglobin
Explanation
Respiratory responses scale with intensity to support gas exchange. Sportbiologie links Atmungssystem to endurance performance.
Question 12Functional anatomy and exercise physiology
Glycolytic (anaerobic lactacid) energy contribution becomes especially important when…
- High-intensity efforts last roughly in the range of tens of seconds where phosphagen alone is insufficient Correct answer.
- Sleeping at night with no muscular work
- Ultra-endurance days at very low intensity only
- Static reading without movement
Explanation
As duration extends beyond a few seconds of max effort, anaerobic glycolysis contributes substantially before aerobic pathways dominate longer work.
Question 13Functional anatomy and exercise physiology
Why can two athletes with identical external pace show different internal loads?
- Differences in economy, heat, altitude, fitness, and individual physiology change oxygen cost and strain at the same speed Correct answer.
- External pace always equals internal load exactly for all humans
- Heart rate cannot vary between people
- Laws of physics forbid individual differences
Explanation
Belastung vs. Beanspruchung: same external load can yield different internal responses-central for individualized Steuerung (Karvonen, Borg, tests).
Question 14Functional anatomy and exercise physiology
Integrate energy systems and method choice: for a 4×4 min hard effort with 3 min incomplete rest, which framing is best?
- Primarily aerobic with substantial anaerobic contribution; interval structure accumulates stress-monitor recovery quality Correct answer.
- Pure phosphagen only with full recovery like max singles
- No metabolic stress by definition
- Only flexibility adaptation
Explanation
Four-minute hard bouts are largely aerobic but recruit anaerobic support; incomplete 3 min rests keep strain elevated-classic interval logic.
Question 15Functional anatomy and exercise physiology
Which statement best links Herzkreislauf adaptations to endurance performance explanation tasks?
- Higher stroke volume and capillarization improve oxygen delivery and extraction supporting sustainable power output Correct answer.
- The heart shrinks usefully in all endurance athletes as the main adaptation
- Capillaries disappear with training
- Oxygen delivery is irrelevant to endurance
Explanation
Explain performance via delivery (cardiac output, hemoglobin, capillaries) and utilization (mitochondria)-a frequent Sporttheorie causal chain.
Question 16Energy systems and training principles
What does the training principle of progressive overload primarily require?
- Gradually increasing training load over time so the body must adapt Correct answer.
- Keeping every session identical forever
- Training only when completely exhausted
- Avoiding all recovery days
Explanation
Progressive overload means systematically raising stimulus (volume, intensity, or complexity) so adaptations continue. Without progression, performance plateaus.
Question 17Energy systems and training principles
Which statement best defines aerobic endurance training?
- Training that relies predominantly on oxidative ATP resynthesis over longer durations with relatively lower intensity Correct answer.
- Only maximal 5-second efforts with full rest
- Training that never elevates heart rate above resting
- Exclusive isometric holds without breathing
Explanation
Aerobic endurance emphasizes oxygen-dependent energy supply for prolonged work. Intensity is typically submaximal relative to sprint or anaerobic-lactacid efforts.
Question 18Energy systems and training principles
The Karvonen formula is primarily used to estimate what?
- Training heart-rate targets from resting and maximal heart rate Correct answer.
- Exact muscle fiber percentages from a blood test
- Body mass index only
- Bone mineral density
Explanation
Karvonen uses heart-rate reserve (HRmax − HRrest) to set intensity zones as a percentage of that reserve plus resting HR-common in Ausdauer training control in Sporttheorie.
Question 19Energy systems and training principles
Which conditional ability is primarily about resisting fatigue over prolonged work?
- Endurance (Ausdauer) Correct answer.
- Maximal strength only
- Reaction time only
- Flexibility only
Explanation
Ausdauer is the ability to sustain load and resist fatigue. Strength, speed, and flexibility are related but distinct domains.
Question 20Energy systems and training principles
Which training method typically alternates work intervals with incomplete recovery?
- Interval method (Intervallmethode) Correct answer.
- Only complete rest for days between every single repetition with no structure
- Avoiding all intensity variation forever
- Sleeping during every work bout
Explanation
Intervallmethode uses repeated loads separated by incomplete recovery so metabolic and cardiovascular stimuli accumulate-central in Ausdauertraining content.
Question 21Energy systems and training principles
Which best describes the Dauer method (Dauermethode) in endurance training?
- Continuous work at a planned intensity without the classic short incomplete-rest interval pattern Correct answer.
- Only 3-second maximal sprints
- Complete inactivity
- Strength training with maximal loads only
Explanation
Dauermethode is continuous endurance work (steady or varied continuous forms). It contrasts with interval and repetition methods.
Question 22Energy systems and training principles
Flexibility (Beweglichkeit) training primarily targets…
- Range of motion around joints through appropriate stretching and mobility work Correct answer.
- Maximal oxygen uptake only
- Reaction to a starter pistol only
- Hemoglobin concentration only
Explanation
Beweglichkeit concerns joint ROM and tissue extensibility. It is a distinct training target alongside strength, endurance, and speed.
Question 23Energy systems and training principles
Why is incomplete recovery central to many interval-training designs?
- It sustains elevated metabolic and cardiovascular stress across repetitions so specific adaptations accumulate Correct answer.
- It guarantees zero lactate forever
- It removes the need to plan intensity
- It replaces the cool-down legally required in all sports rules
Explanation
Incomplete recovery keeps heart rate, oxygen debt, and metabolic strain elevated, shaping the stimulus. Complete recovery would change the method toward Wiederholungsmethode qualities.
Question 24Energy systems and training principles
Why is periodization used in training planning?
- To structure cycles (e.g., micro/meso/macro) so load, recovery, and peaking align with goals and competitions Correct answer.
- To ensure every day is maximal failure with no structure
- To remove all testing
- To train only one motor ability forever
Explanation
Periodization organizes progressive and regenerative phases. Sporttheorie planning tasks often expect reasoned cycle thinking, not random hard days.
Question 25Energy systems and training principles
Maximal strength training typically uses which relative intensity character?
- High loads with lower repetitions and ample recovery compared with hypertrophy-endurance circuits Correct answer.
- Only empty-bar cardio forever
- Sleeping as the load
- Exclusive stretching without resistance
Explanation
Krafttraining methods vary by goal: maximal strength emphasizes high intensity, low reps, full recovery; other methods target hypertrophy or strength endurance.
Question 26Energy systems and training principles
Why might altitude training be discussed as a further training form?
- Hypoxic exposure can stimulate hematological and other adaptations, with caveats about individual response and health monitoring Correct answer.
- It instantly teaches basketball tactics
- It removes the need for any sea-level training forever
- It is identical to stretching
Explanation
LehrplanPLUS mentions further forms such as Höhentraining-students should know intended mechanisms and limits, not treat it as magic.
Question 27Energy systems and training principles
Mental training (Mentales Training) in Sporttheorie typically includes…
- Imagery, attention control, and cognitive rehearsal strategies supporting performance and learning Correct answer.
- Only lifting heavier each day
- Avoiding all visualization
- Replacing physical practice entirely for novices always
Explanation
Further training forms include Mentales Training. It complements-not fully replaces-physical practice, especially for beginners needing motor experience.
Question 28Energy systems and training principles
A coach schedules hard interval sessions every day with no regenerative microcycles. Which principle is most clearly violated, and what is the likely risk?
- Recovery/supercompensation timing is ignored, raising overreaching/overtraining and injury risk Correct answer.
- Specificity is perfectly optimized with zero downside
- Only flexibility improves automatically
- ATP demand disappears
Explanation
Without recovery phases, repeated deep fatigue prevents supercompensation and increases maladaptation risk-classic planning error in Trainingslehre evaluation items.
Question 29Energy systems and training principles
Compare Dauermethode and Intervallmethode for developing aerobic capacity: which contrast is most accurate?
- Dauer emphasizes continuous stimulus; intervals use repeated loads with incomplete recovery to accumulate specific internal loads Correct answer.
- Intervals never elevate heart rate
- Dauer always means maximal sprinting only
- Both forbid any intensity planning
Explanation
Both can develop endurance qualities, but the stimulus structure differs: continuous vs. fragmented with incomplete rest. Method choice depends on goals and athlete level.
Question 30Energy systems and training principles
An athlete shows high mitochondrial density but limited phosphagen power. For a 10 s maximal effort sport, which training emphasis is most logical?
- Prioritize high-quality alactic speed/power stimuli with full recovery rather than only long slow distance Correct answer.
- Only add more ultra-distance volume
- Stop all neural quality work
- Rely solely on flexibility circuits
Explanation
Specificity: 10 s max efforts need phosphagen/neural qualities. Aerobic mitochondrial fitness helps other domains but does not replace sprint-power training.
Question 31Mechanical analysis of movement
Which statement best describes the center of mass (Körperschwerpunkt) in biomechanics?
- The point at which the body's mass can be considered concentrated for analysis of translation Correct answer.
- Always fixed exactly at the navel regardless of posture
- A legal sports rule about team captains
- The only muscle that produces force
Explanation
The center of mass is a mechanical reference point for translation and balance analyses. Its location shifts with posture and segment positions.
Question 32Mechanical analysis of movement
Friction in sports movements typically does which of the following?
- Resists relative motion between contacting surfaces and can both enable propulsion and cause energy loss Correct answer.
- Always increases speed with no downside
- Exists only in water sports
- Eliminates all need for muscle force
Explanation
Friction opposes sliding between surfaces. Athletes need enough friction for traction (running, cutting) but excess friction can waste energy.
Question 33Mechanical analysis of movement
Translation in biomechanics refers to…
- Linear motion of a body or segment through space Correct answer.
- Only spoken language interpretation in PE class
- A change in muscle fiber type overnight
- Elimination of all rotation forever
Explanation
Translation = linear displacement of the center of mass or a point. Rotation is angular motion about an axis. Real sports skills usually combine both.
Question 34Mechanical analysis of movement
Which statement about motor learning stages is most accurate at an introductory level?
- Learners typically progress from cognitive (high attention) toward more autonomous, fluent performance with practice Correct answer.
- Elite automaticity appears after one attempt for everyone
- Feedback never matters
- Learning stops when the first error occurs
Explanation
Bewegungslehre covers motorisches Lernen: early stages need attention and feedback; with practice, control becomes more automatic.
Question 35Mechanical analysis of movement
Which description best fits the biomechanical principle of an optimal acceleration path (optimaler Beschleunigungsweg)?
- Applying force over a suitably long path/time so the implement or body can be accelerated effectively before release or take-off Correct answer.
- Stopping force application as early as possible in every throw
- Ignoring run-up in javelin always
- Maximizing air resistance intentionally in sprints
Explanation
Many throwing/jumping analyses emphasize using a long, well-directed acceleration path so impulse can build velocity before release.
Question 36Mechanical analysis of movement
Coordination of partial impulses (Koordination der Teilimpulse) means…
- Timing and directing segmental contributions so forces add constructively toward the intended goal Correct answer.
- Moving segments randomly in opposite useful directions
- Using only one joint forever
- Avoiding any sequential timing
Explanation
Complex skills (throws, kicks) succeed when segmental impulses are sequenced and aligned rather than cancelling each other.
Question 37Mechanical analysis of movement
Angular motion about a body axis is called…
- Rotation Correct answer.
- Only pure translation with no angle change
- Diffusion of oxygen
- Glycolysis
Explanation
Rotation involves angular displacement about an axis (longitudinal, sagittal, transverse). Sports skills combine rotation and translation.
Question 38Mechanical analysis of movement
A stable equilibrium situation is more likely when…
- The center of mass projects well within a sufficiently large base of support and is relatively low Correct answer.
- The base of support is minimized to a single toe while COM is high and outside
- Friction is zero on ice with no edges
- The athlete closes eyes and leans beyond the base intentionally without control
Explanation
Balance depends on COM projection relative to the base of support, COM height, and friction/edge control-core Gleichgewicht content.
Question 39Mechanical analysis of movement
Functional movement analysis asks mainly…
- Why the movement is structured as it is relative to the goal and constraints (causes/purposes) Correct answer.
- Only the jersey color
- Whether the athlete liked the music
- The cafeteria menu
Explanation
Functional analysis links form to function: how technique serves task goals under rules and physical constraints.
Question 40Mechanical analysis of movement
Intrinsic feedback in motor learning refers to…
- Sensory information the learner obtains from performing the movement itself Correct answer.
- Only teacher grades mailed a year later
- Random noise unrelated to the task
- Doping laboratory reports
Explanation
Learners use vision, proprioception, and outcome senses. Teachers add augmented feedback, but intrinsic information is foundational.
Question 41Mechanical analysis of movement
Conservation of angular momentum (when external net torque ≈ 0) implies…
- Reducing moment of inertia increases angular velocity, and vice versa Correct answer.
- Tucking always slows spin
- Extending always speeds spin
- Angular velocity is unrelated to body configuration
Explanation
With L ≈ Iω roughly conserved, decreasing I raises ω (tuck), increasing I lowers ω (extend).
Question 42Mechanical analysis of movement
In a jump take-off analysis, applying large force too late after leaving the ground fails because…
- Once airborne without contact, the athlete cannot generate additional ground reaction impulse Correct answer.
- Air always provides infinite reaction force
- Impulse is irrelevant to momentum change
- Mass becomes zero at take-off
Explanation
Impulse–momentum requires interaction with the ground (or implement). After toe-off, COM motion is largely ballistic aside from air resistance and mid-air configuration changes for rotation.
Question 43Mechanical analysis of movement
Principle of initial force (Prinzip der Anfangskraft) is best illustrated by…
- Pre-tensing/activating the muscle-tendon system so subsequent acceleration starts from a higher force level Correct answer.
- Beginning every movement from complete muscle silence as ideal
- Avoiding any eccentric pre-load in stretch-shortening skills
- Throwing without a run-up always being superior for impulse
Explanation
Many techniques use preparatory tension or countermovement so the propulsive phase starts effectively-linked to stretch-shortening discussions.
Question 44Mechanical analysis of movement
A learner plateaus despite high repetition of one rigid technique model. Which evidence-based adjustment fits differentielles Lernen?
- Introduce structured variation of parameters to expand the attractor landscape, then re-stabilize toward task success Correct answer.
- Punish every deviation more harshly
- Reduce all feedback to zero permanently without redesign
- Replace practice with theory reading only
Explanation
Differential learning uses variability productively. Pure endless identical reps can entrench a limited solution; smart variation can unlock progress, then refine.
Question 45Mechanical analysis of movement
A gymnast tucks tightly mid-air. Which mechanical account is most coherent?
- Decreasing moment of inertia about the rotation axis increases angular velocity if angular momentum is largely conserved Correct answer.
- Mass increases, forcing slower spin always
- Friction with the ground increases mid-air
- Translation ceases whenever rotation occurs
Explanation
Aerial configuration changes redistribute mass relative to the axis, altering I and thus ω under approximate angular-momentum conservation.
Question 46Motor control, learning and feedback
In Fitts and Posner's stages of motor learning, what stage is characterized by high cognitive demand, frequent errors, and reliance on explicit feedback?
- Associative stage
- Autonomous stage
- Reflexive stage
- Cognitive stage Correct answer.
Explanation
The cognitive stage is the initial phase of skill learning where the novice tries to understand 'what to do', committing gross errors and requiring external instruction.
Question 47Motor control, learning and feedback
A teacher observes a kindergartner who can run but still uses a wide base of support and has difficulty stopping quickly. According to motor development theory, which category of motor skill is this child demonstrating?
- Fundamental locomotor skill Correct answer.
- Specialized sport skill
- Reflexive movement
- Fine motor manipulation
Explanation
Running is a fundamental locomotor skill, one of the basic movement patterns (running, jumping, hopping, skipping) children develop in early childhood. A wide base of support and difficulty stopping indicate the child is still refining this fundamental pattern. Specialized sport skills build on these fundamentals later.
Question 48Motor control, learning and feedback
During the cognitive stage of Fitts and Posner's model of motor learning, a learner primarily focuses on which of the following?
- Automatically executing the skill while attending to strategy
- Understanding the task and what to do, often making large, frequent errors Correct answer.
- Refining minor errors with consistent, smooth performance
- Performing the skill without any conscious attention
Explanation
In Fitts and Posner's cognitive (verbal-cognitive) stage, the learner is trying to understand the goal and mechanics of the task. Performance is inconsistent and errors are large and frequent as the learner figures out what to do. This precedes the associative and autonomous stages.
Question 49Motor control, learning and feedback
Which type of feedback is provided by a coach who tells a sprinter, 'Your start was slow because you didn't drive your arms,' rather than just stating the finishing time?
- Knowledge of results (KR)
- Intrinsic feedback
- Knowledge of performance (KP) Correct answer.
- Proprioceptive feedback
Explanation
Knowledge of performance (KP) is augmented feedback about the quality or movement pattern of the action, such as arm drive technique. Knowledge of results (KR) concerns the outcome (the time). KP helps the learner improve the movement itself.
Question 50Motor control, learning and feedback
When a baseball outfielder runs to catch a fly ball, the brain continuously updates the body's position using sensory information. This ongoing correction of movement based on feedback is characteristic of which type of motor control?
- Closed-loop control Correct answer.
- Open-loop control
- Reflexive control
- Ballistic control
Explanation
Closed-loop control uses continuous sensory feedback to monitor and adjust an ongoing movement. Catching a moving ball requires constant corrections based on visual and proprioceptive input, making it closed-loop. Slow or continuous tasks generally rely on closed-loop processing.
