03 / ONE SESSION, TWO VIEWS

Athlete and coach see the same session.

Athletes enter less. Coaches chase fewer updates. Reps, status, and notes stay together.

See completion and fading times without asking one by one.

REVIEW: Outliers, late fade, athlete notes

04 / NEXT SESSION

Build the record first. Then adjust what comes next.

AccelPhase can draft the next session from recent sprint records, but it cannot assign that draft. The coach edits, rejects, or approves it before publishing.

AI PLAN DRAFT

COACH REVIEW REQUIRED

BASED ON 4 RECENT SPRINT SESSIONS

Draft: reduce the final two reps from 90% to 87% effort and add 30 seconds of recovery.

Why: the last two sessions faded from rep 3, while reported fatigue also rose in the final reps.

BUILT FOR ACCOUNTABLE DECISIONS

Technical depth that keeps the coach in control.

01
One team plan. Every athlete checked.
AccelPhase evaluates whether each athlete can follow the shared plan or needs an individual adjustment.
02
Every suggestion has a reason.
The system separates recorded facts, calculated results, rule-based decisions, and AI-generated interpretation.
03
AI drafts must pass code rules.
Structured outputs are checked for missing data, invalid changes, conflicting advice, and major adjustments before reaching the coach.
04
Nothing becomes a decision automatically.
The coach reviews, modifies, approves, or rejects every plan adjustment and athlete feedback draft.

05 / WHY ACCELPHASE

Keep every sprint decision in one connected context.

Spreadsheets split the plan from messages, athlete responses, and the next decision.

Shared plan, individual checks

One shared base plan is checked athlete by athlete.

Assignment through next plan

Assignment, results, coach review, feedback, and next-plan context stay connected.

AI-assisted, coach-owned

AI assists the decision. The coach owns it.

Sprint-specific focus

Built for sprint-specific work, not generic activity tracking.

Built as an independent student project for clearer sprint coaching decisions.

What is AccelPhase?

AccelPhase is a sprint-team management system with AI-assisted, athlete-by-athlete decision support. It keeps plan assignment, completion, coach review, feedback, and next-plan context connected.

Does AI publish or change a plan automatically?

No. AI prepares briefs and drafts; server rules validate them, and the coach reviews the result before a plan or adjustment is published.

What happens when data are missing or incomparable?

Missing values remain missing, conclusions are downgraded, and incompatible distances, timing methods, or training purposes are not silently compared.
