GPS Monitoring in Sports

What does GPS monitoring allow coaches to measure in order to develop an activity profile?

• Heart rate

• Different velocities

• Player height

• Team morale

What do top-class international players spend more time doing compared to moderate players?

• Low-intensity actions

• High-intensity actions

• Resting

• Walking

What does an elevated blood lactate level (>5mM) at the end of a football match tell us

• Increased usage of anaerobic glycolysis

• It was an easy match

• The player was on the bench

• Increased reliance on aerobic metabolism

Why might most goals be scored in the final minutes of a match?

• Players are more motivated

• Players are less fatigued

• Players have impaired sprinting ability

• Players are more focused

What does the graph indicate about sprint performance after an intense period in the second half?

• Sprint performance improves

• Sprint performance remains the same

• Sprint performance declines

• Sprint performance is unpredictable

What is the primary source of energy during the last sprint according to the figure?

• ATP

• PCr

• Glycolysis

• Aerobic

What does a higher expression of type IIA fibres potentially provide in sprint performance?

• Increased fatigue during sprinting activities.
• Improved speed and power output in sprint performance.
• Reduced muscle recovery time after sprints.
• Decreased endurance in long-distance running.

What is the typical work to recovery ratio in high-intensity interval sessions?

• 1:2

• 1:1

• 2:1

• 3:1

What is the role of PGC-1a

• PGC-1α is primarily involved in muscle contraction.
• PGC-1α regulates energy metabolism and mitochondrial biogenesis.
• PGC-1α is a hormone that regulates blood sugar levels.
• PGC-1α functions as a neurotransmitter in the brain.

Why is Citrate Synthase an important enzyme?

• Citrate Synthase is responsible for DNA replication.
• Citrate Synthase is involved in protein synthesis.
• Citrate Synthase breaks down fatty acids for energy.
• Citrate Synthase is important because it is the rate limiting enzyme in the formation of Citrate
