Which muscle group is primarily responsible for knee extension during a squat?
Hamstrings
Gastrocnemius
Quadriceps femoris
Gluteus maximus
The quadriceps femoris muscle group is the main agonist for knee extension. Hamstrings function mainly in knee flexion, gastrocnemius in plantarflexion, and gluteus maximus in hip extension.
Which joint type allows movement in multiple planes, as seen in the shoulder?
Pivot joint
Ball-and-socket joint
Hinge joint
Saddle joint
The ball-and-socket joint of the shoulder allows motion in multiple planes, including flexion, extension, abduction, adduction, and rotation. Other joints like hinge and pivot are more limited in movement.
Which energy system predominantly fuels a 10-second sprint?
Anaerobic glycolysis
Oxidative phosphorylation
Phosphofructokinase system
ATP-PC system
The ATP-PC (phosphocreatine) system provides immediate ATP for high-intensity efforts lasting up to about 10 seconds. Glycolysis and oxidative systems contribute more during longer activities.
During moderate-intensity aerobic exercise, how does heart rate change relative to rest?
It decreases below resting levels
It increases linearly with intensity
It remains the same
It fluctuates randomly
Heart rate increases in a roughly linear fashion with exercise intensity to meet the oxygen demands of working muscles. It does not remain constant or decrease during activity.
Which muscle acts as the primary agonist during elbow flexion?
Brachioradialis
Deltoid
Biceps brachii
Triceps brachii
The biceps brachii is the main muscle responsible for flexing the elbow joint. The triceps brachii extends the elbow, brachioradialis assists to a lesser extent, and the deltoid is a shoulder mover.
Which muscles are the primary plantarflexors of the ankle during push-off in running?
Tibialis anterior
Soleus
Peroneus longus
Gastrocnemius and soleus
Both the gastrocnemius and soleus muscles generate the majority of plantarflexion force during the push-off phase of running. Tibialis anterior dorsiflexes the ankle and peroneus muscles evert the foot.
What happens to stroke volume during incremental exercise as intensity increases to near maximal levels?
It plateaus after moderate intensity
It remains unchanged
It decreases due to fatigue
It continuously increases until maximal intensity
Stroke volume increases with exercise intensity up to a moderate level and then plateaus despite further increases in workload. This plateau occurs even as heart rate continues to rise.
In biomechanics, what does the term 'moment arm' refer to?
The velocity of a moving limb segment
The distance between the center of mass and the ground
The length of muscle fibers
The perpendicular distance from the joint axis to the line of action of the force
A moment arm is the perpendicular distance from a joint's axis of rotation to the line of action of a force, determining torque. It is not related to segment velocity or fiber length.
Lactate threshold refers to the exercise intensity at which:
Lactate production exceeds lactate clearance
Muscle glycogen stores are depleted
Heart rate first plateaus
VO2 max is reached
The lactate threshold is marked by an accumulation of lactate in the blood when production surpasses clearance. It is not synonymous with VO2 max or glycogen depletion.
What class of lever is represented by a biceps curl?
First-class lever
Second-class lever
Fourth-class lever
Third-class lever
A biceps curl is a third-class lever, where the effort (muscle force) is applied between the fulcrum (elbow joint) and the load (weight in hand).
During steady-state aerobic exercise, how do systolic and diastolic blood pressures typically respond?
Both increase significantly
Systolic increases, diastolic stays the same or slightly decreases
Systolic stays the same, diastolic increases
Both decrease below resting levels
Systolic blood pressure rises to increase blood flow during exercise, while diastolic pressure remains relatively stable or may slightly decrease due to vasodilation.
The primary site of gas exchange in the lungs is the:
Pulmonary artery
Trachea
Bronchioles
Alveoli
Alveoli are tiny air sacs with thin walls that facilitate diffusion of oxygen into and carbon dioxide out of the bloodstream. Other structures conduct air but do not primarily exchange gases.
How does shifting the center of mass forward affect stability in a sprinter's starting position?
It has no effect on stability
It decreases stability
It increases stability
It prevents force production
Moving the center of mass forward increases stability by keeping it over the base of support. This position also aids in force application at the start of a sprint.
Which energy system contributes most to ATP resynthesis during a 400-meter race lasting 45 - 60 seconds?
Anaerobic glycolysis
Oxidative phosphorylation
ATP-PC system
Electron transport chain
Anaerobic glycolysis supplies the majority of ATP for high-intensity efforts lasting around one minute. The ATP-PC system is too brief and oxidative pathways too slow for peak energy in this duration.
Type I muscle fibers are characterized by:
Fast contraction speed
High glycolytic capacity
Few mitochondria
High oxidative capacity
Type I (slow-twitch) muscle fibers have high mitochondrial density and oxidative capacity, making them fatigue-resistant. Fast contraction and high glycolytic capacity describe Type II fibers.
Which cardiovascular adaptation contributes most to an increased VO2 max following endurance training?
Increased maximal heart rate
Decreased capillary density
Increased stroke volume
Reduced blood volume
Endurance training increases stroke volume through cardiac hypertrophy and improved venous return, which enhances cardiac output and VO2 max. Maximal heart rate changes minimally.
During the muscle cross-bridge cycle, which event directly triggers the power stroke?
ATP binding to the myosin head
Release of ADP from myosin
Actin binding to tropomyosin
Release of inorganic phosphate from myosin
The release of inorganic phosphate from the myosin head causes a conformational change, pulling actin and generating the power stroke. ATP binding and ADP release occur at other cycle stages.
Calculate the torque produced by a muscle force of 200 N acting at a moment arm of 0.04 m.
5 Nm
80 Nm
0.008 Nm
8 Nm
Torque is calculated as force multiplied by the moment arm (200 N × 0.04 m = 8 Nm). The other values result from incorrect multiplication or unit errors.
What is the mechanical advantage of a lever with an effort arm of 0.3 m and a load arm of 0.05 m?
6
0.167
1.67
0.015
Mechanical advantage is the ratio of effort arm to load arm (0.3 m ÷ 0.05 m = 6). The other ratios reflect calculation mistakes.
Which mechanism best describes central fatigue during prolonged endurance exercise?
Reduced motor cortex activation
Depletion of muscle glycogen
Increased peripheral nerve conduction
Accumulation of lactate within muscles
Central fatigue involves reduced neural drive from the motor cortex to muscles during prolonged exercise. Lactate accumulation and glycogen depletion are peripheral factors, not central mechanisms.
