What does this research mean for the field?

Individual daily heart rate variability analyses detect substantial individual changes in cardiac autonomic responses after a soccer match in both First Eleven and Reserve players, whereas group analyses only detect significant changes in First Eleven players.

Individual versus team heart rate variability responsiveness analyses in a national soccer team during training camps

Q: What are the key findings of this study?

Individual daily heart rate variability analyses detected substantial individual changes in cardiac autonomic responses after a soccer match in both First Eleven and Reserve players.

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Healthy professional soccer players (n=34). Intervention: First Eleven (played main squad ≥60 min) vs. Reserves (did not play or played <60 min). Primary outcome: Time*Group interaction from match-day 1 to match-day+1 in LnRMSSD (η2p 0.13, p=0.034).

Key result

Soccer matches linked to substantial individual changes in cardiac autonomic responses on daily HRV analysis.

η2p 0.13
P=0.034
n=34

Why the study?

Heart rate variability analyses can be performed using group or individual changes, and individual changes could be of potential interest during training camps for national soccer teams.

Does individual daily HRV analysis detect changes in cardiac autonomic responses better than group analysis in professional soccer players after a match?

Population

34 professional soccer players

Comparison

First Eleven vs Reserves, and individual daily HRV vs group changes

Follow-up

9 days

Implication

Individual HRV monitoring may detect post-match autonomic shifts missed by group averages; leaves open prospective validation before guiding athlete recovery.

Does individual daily HRV analysis detect changes in cardiac autonomic responses better than group analysis in professional soccer players after a match?

Population

34 male professional soccer players from a European national soccer team, mean age 25.3 years. Divided into First Eleven (n=17) and Reserves (n=17).

Intervention

Playing a soccer match (First Eleven group, played a minimum of 60 min)

Comparator

Reserves group (played less than 60 min or did not play)

Outcome

Changes in daily heart rate variability (LnRMSSD and Stress Score) analyzed individually versus as a groupsurrogate

Main Result

Effect estimate: η2p 0.13

p-value: p=0.034

Individual daily HRV analysis detects cardiac autonomic responses to match stress that are masked when using traditional group-level averages.

Limitations

Small sample size
More research is needed to understand the relationship between the observed changes and other important fatigue variables such as wellness measures and other physiological and mechanical outputs

Muñoz‐López et al. (2020) conducted a cross-sectional in Healthy professional soccer players (n=34). First Eleven (played main squad ≥60 min) vs. Reserves (did not play or played <60 min) was evaluated on Time*Group interaction from match-day 1 to match-day+1 in LnRMSSD (η2p 0.13, p=0.034). Individual daily heart rate variability analyses detected substantial individual changes in cardiac autonomic responses after a soccer match in both First Eleven and Reserve players.
