What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine the effect of EnXtra® and EnXtra® + Caffeine on alertness score as assessed by the change in the Jin Fan Alertness score as compared to placebo and caffeine in Acute stage.

    The Attention Network Test (ANT) is an assessment tool to evaluate efficacy of three distinct attention networks: alerting, orienting, and executive networks.

    Alerting effect = mean Response Time (RT) (correct no cue) - mean RT (correct centre cue) Orienting effect = mean RT (correct centre cue) - mean RT (correct spatial cue) Conflict effect = mean RT (correct incongruent) - mean RT (correct congruent) Correct: correctness of response No cue condition: participant does not receive any cue before the target stimulus appears.

  1. To determine the effect of EnXtra® and EnXtra® + Caffeine on Eye-hand coordination as assessed by Nine hole peg test (NHPT) as compared to placebo and caffeine in Acute stage.

    The NHPT assesses eye-hand coordination in individuals. This study focuses on the dominant hand's performance.

    Metrics recorded for assessment:

    Moving Duration - 1: Time to move the first peg from the holder to the board, indicating initial movement speed and fluidity.

    First Peg Selection - 1: Time from the start of the test until the first peg is picked up, indicating readiness and initial response speed.

    Transport Drops - 1: Number of times the first peg is dropped during transport, assessing precision and control.

    Moving Duration - 2: Similar to Moving Duration - 1 for the second peg, providing insight into consistency and endurance over multiple attempts.

    First Peg Selection - 2: Time taken to select the first peg again, measuring sustained attention and readiness.

    Transport Drops - 2: No. of drops during the second transport attempt, evaluating precision and control.

    An increase in moving duration indicates a decline in eye-hand coordination speed.

  3. To determine the effect of EnXtra® and EnXtra® + Caffeine on Sustained attention as assessed by Continuous Performance test (CPT) as compared to placebo and caffeine in acute stage.

    This task is primarily designed to measure selective and sustained attention, with some capacity to assess impulsivity to a lesser degree. CPT measures sustained attention and response time. Sustained attention is measured by assessing how well participants can maintain their focus throughout the test. The response time is measured by calculating the average time it takes for a participant to respond to target stimuli. In the CPT, a decline in sustained attention is often reflected in increased response times and greater variability. This can occur as participants become fatigued or distracted over time, leading to slower and less consistent responses.Hence, a long response time may suggest cognitive slowing and/or impairment.

    Measured: Day 0; Day 5; Day 10; Day 15 - 0, 1, 3 & 5 hours ±15 minutes post IP

  4. To determine the effect of EnXtra® and EnXtra® + Caffeine on Sustained attention as assessed by Continuous Performance test (CPT) as compared to placebo and caffeine in sub-acute stage.
