Spanish health professionals reiterated in July 2026 that the surge of unqualified individuals offering personal‑training advice online threatens public safety. The president of the Catalan Association of Fitness Companies called for recognised credentials—such as university degrees in Physical Activity and Sport or certified technical diplomas—and noted that regulatory standards differ across Spain’s autonomous communities. The same commentary highlighted the well‑known seasonal drop in exercise during summer, warning that short breaks can evolve into prolonged disengagement, poorer sleep and reduced wellbeing.

In August 2026, a pan-European analysis of 417,362 children and adolescents (ages 6–16) from 20 countries, covering data from 1965–2023, confirmed a long-term downward trend in youth fitness. Cardiorespiratory endurance, which rose until the early 1980s, has been falling since and remains below historic levels. Upper-body muscle strength has declined since the 1970s, while leg strength peaked in the 1980s before dropping. Flexibility has steadily worsened, with an accelerated decline after 2000; these negative trends are more pronounced in boys. Research indicates that body fat mass has seen a constant increase.

In Portugal, specific data from the National Institute of Statistics reveals that nearly 40% of children aged 5 to 14 are overweight or obese. Obesity is more prevalent in boys (15%) than girls (10.7%), with high consumption of ultra-processed foods and sugary drinks—including approximately 81,000 children consuming sodas daily—noted as contributing factors. Regional variations in Portugal show the highest rates in the Azores, the North, and Madeira. Researchers continue to urge greater investment in physical-activity programmes and a standardized European monitoring system.
