Algorithm (wastani wa mzunguko wa sekunde 30):

Kwa nini Kipeuo cha 4?

Uhusiano wa kipeuo cha nne (quartic) unaonyesha gharama isiyo ya mshazari ya kifiziolojia ya juhudi zinazobadilika. Safari yenye surges na mapumziko inagharimu nishati zaidi kuliko nguvu thabiti katika wastani ule ule.

Utekelezaji wa JavaScript:

function calculateNormalizedPower(powerData) {
  // powerData ni mfululizo (array) wa thamani za nguvu za kila sekunde

  // Hatua ya 1: Kokotoa wastani wa mzunguko wa sekunde 30
  const rollingAvgs = [];
  for (let i = 29; i < powerData.length; i++) {
    const window = powerData.slice(i - 29, i + 1);
    const avg = window.reduce((sum, p) => sum + p, 0) / 30;
    rollingAvgs.push(avg);
  }

  // Hatua ya 2: Pandisha kwa kipeuo cha 4
  const powered = rollingAvgs.map(p => Math.pow(p, 4));

  // Hatua ya 3: Wastani wa vipeuo vya 4
  const avgPowered = powered.reduce((sum, p) => sum + p, 0) / powered.length;

  // Hatua ya 4: Tafuta kipeuo cha nne
  const np = Math.pow(avgPowered, 0.25);

  return Math.round(np);
}

// Mfano wa utumiaji:
const powerData = [/* array ya nguvu ya kila sekunde */];
const np = calculateNormalizedPower(powerData);
// Inarudisha: NP katika wati

Milinganyo (Exponentially Weighted Moving Averages):

Ufafanuzi wa Vipimo:

• CTL (Chronic Training Load): wastani wa mzunguko wa siku 42 - unawakilisha fitinesi
• ATL (Acute Training Load): wastani wa mzunguko wa siku 7 - unawakilisha uchovu
• TSB (Training Stress Balance): Hali (Form) = Fitinesi - Uchovu

Mfano wa Ukokotoaji (Kipindi cha siku 7):

Ufafanuzi wa TSB:

Utekelezaji wa JavaScript:

function calculatePMC(workouts) {
  // workouts = [{date: "YYYY-MM-DD", tss: number}, ...]
  let ctl = 0, atl = 0;
  const results = [];

  workouts.forEach(workout => {
    // Badilisha CTL (siku 42)
    ctl = ctl + (workout.tss - ctl) / 42;

    // Badilisha ATL (siku 7)
    atl = atl + (workout.tss - atl) / 7;

    // Kokotoa TSB (CTL ya jana - ATL ya leo kwa njia ya kawaida)
    const tsb = ctl - atl;

    results.push({
      date: workout.date,
      tss: workout.tss,
      ctl: Math.round(ctl * 10) / 10,
      atl: Math.round(atl * 10) / 10,
      tsb: Math.round(tsb * 10) / 10,
      status: getTSBStatus(tsb)
    });
  });

  return results;
}

function getTSBStatus(tsb) {
  if (tsb < -30) return "Hatari Kubwa";
  if (tsb < -10) return "Mafunzo Magumu";
  if (tsb < 5) return "Bora";
  if (tsb < 15) return "Tayari kwa Mbio";
  return "Kupoteza Fitinesi";
}

// Mfano wa utumiaji:
const workouts = [
  {date: "2025-01-01", tss: 100},
  {date: "2025-01-02", tss: 50},
  {date: "2025-01-03", tss: 120},
  // ... mazoezi mengine
];

const pmc = calculatePMC(workouts);
// Inarudisha array yenye CTL, ATL, TSB ya kila siku
