Turning Internal Load into Microcycle Clarity: Practical Use of Firstbeat for Daily Training Decisions

Dr. James Malone, who mentors football physical coaches and sport scientists and previously worked at Liverpool and Everton, shows how performance staff can use heart rate data to plan each day of the microcycle and decide when to push players and when to hold them back.

About this webinar

In this 45-minute session, recorded on 3 March 2026, Malone works through internal load data from the Firstbeat Sports platform: individual balance ranges, quick recovery test (QRT) scores across the week, and example training impulse (TRIMP) targets for each day, which Firstbeat provided as rough estimates. He covers recovery after a match, readiness for the loading days, changing a drill without losing intensity, submaximal testing and non-starters in congested weeks. Malone spent around eight years as a senior lecturer in sport science and is a research fellow at the University of Southern Denmark.

What you will learn

• Example targets for the two loading days, MD-4 and MD-3: 150–180 TRIMP, a peak 4-minute TRIMP/min of 2.6–3.2 and about 55–70% of match load.
• Why a red QRT score on MD+1 is expected, and what the MD+2 score should do before the first loading day.
• How to cut a 3×3-minute small-sided game to 2×3 for a player who is still recovering, without dropping the intensity.
• How submaximal heart rate and the QRT together tell acute fatigue, deconditioning and positive adaptation apart.
• A four-bucket model that sorts players from full session to modified programme.

Practical examples from the recording

1. Loading days and taper days. In Malone’s example week, MD-4 and MD-3 are the loading days. On each he expects around 150–180 TRIMP, a peak 4-minute TRIMP/min of about 2.6–3.2, and aerobic and anaerobic training effect up around 4. That is roughly 55–70% of match load. On MD-2 and MD-1, TRIMP comes down to about 20–25% of match while intensity stays fairly high. His taper follows one rule: hold intensity at around 90% of normal and drop the volume.

2. Reading recovery on MD+1 and MD+2. A red QRT score on MD+1 is what Malone expects after a match, so on its own it is no reason to panic. MD+2 is the day to watch. If the score moves from red towards amber or green, the planned MD-4 session goes ahead. If it barely improves, he follows the trend into MD-4 rather than one number. Pulling the player from training is a last resort; he goes into the next day’s planning conversation instead.

3. Cutting volume, not intensity. In Malone’s example the full drill is a 6v6 with two neutral players, 3×3 minutes with 3 minutes of active rest, a 1:1 work-to-rest ratio. For a player still struggling in the 72 hours after a match, volume changes first: 2×3 instead of 3×3, ideally at the same work-to-rest ratio. If he needs more rest, he skips a round and joins the next one. It depends on the head coach, but taking away volume while keeping the intent of the drill often works well.

4. Submaximal testing to separate fatigue from deconditioning. Malone uses a fixed-intensity submaximal test, run-based or with the ball in the warm-up, tracks heart rate drift over time and reads it next to the QRT. Higher submax heart rate with a suppressed QRT points to acute fatigue, so he keeps intensity and cuts volume. Higher submax heart rate with a stable QRT points to deconditioning, often in non-starters, and he sees more aerobic exposure as the only fix. Lower submax heart rate with everything else stable means the player is adapting, so the stimulus progresses. In one-game weeks he tests on MD-4; in congested weeks, on MD-1.

Questions answered in the Q&A

How many spikes beyond the balance range should worry you? It depends on the phase. When the block lets you push players, going beyond the balance range makes sense; in a maintenance phase, stay inside it. Spikes on MD-4 and MD-3 are expected in Malone’s model. Very hard sessions on MD-2 or MD-1 are what would concern him.

Can Firstbeat be used alongside the wearables players already have? In theory yes, Malone says. Its strength is data from the training session itself, where in his experience other devices’ heart rate is poor. The QRT is short, so players can do it alongside a 24/7 device, though some will ask why they are doing both.

When should non-starters get top-ups in a two-game week? Use every opportunity: straight after the match and on MD+1. Post-match time on the pitch is limited, about 15 minutes in the Premier League as far as Malone knows, which leaves 5–10 minutes for basic running intervals. A pre-match session for players outside the squad hurt morale, and he does not recommend it.

Do players listen when the data says to back off? It depends on the player. Malone sees high-profile players who ask about their data and respond well, players set in their ways who ignore it, and young players fighting for a first-team place whose heart rate goes through the roof almost every session. They are the hardest to manage.

Who this webinar is for

Heads of performance, sport scientists and strength and conditioning coaches in professional football who plan the microcycle and take the numbers to the head coach. It helps when you decide, player by player, who trains in full, who gets less volume and who needs extra conditioning.
