Question 1

Heart rate variability (HRV) monitoring in athletes is primarily used to assess:

Accepted Answer

Autonomic nervous system balance and day-to-day recovery status

Answer

HRV reflects the influence of the sympathetic and parasympathetic nervous systems on heart rhythm; suppressed HRV typically indicates accumulated fatigue or incomplete recovery.

Question 2

Actigraphy wristbands worn by athletes around the clock are commonly used to monitor:

Accepted Answer

Sleep duration, sleep quality, and daily activity levels

Answer

Actigraphs use accelerometers to infer sleep-wake cycles and movement throughout the day, providing objective sleep and activity data without polysomnography.

Question 3

An athlete management system (AMS) such as Smartabase or Kitman Labs is primarily designed to:

Accepted Answer

Centralize wellness, training load, and performance data for the multidisciplinary team

Answer

An AMS serves as a hub where coaches, sports scientists, and medical staff share athlete data (wellness, load, GPS, testing) to inform collaborative decision-making.

Question 4

Session-RPE multiplied by session duration (in minutes) calculates:

Accepted Answer

Internal training load in arbitrary units

Answer

The Foster session-RPE method quantifies internal load: RPE (Borg CR-10) × duration = arbitrary units that reflect the athlete's perceived physiological strain.

Question 5

Near-infrared spectroscopy (NIRS) sensors placed over a muscle during exercise primarily measure:

Accepted Answer

Muscle oxygen saturation (SmO2) and oxygenated hemoglobin flux

Answer

NIRS uses near-infrared light absorption by hemoglobin to continuously measure the balance of oxygen delivery and consumption within the underlying muscle.
