In 2025, Beiwang Deng and team from Guangzhou Sport University conducted a systematic review and network meta-analysis to evaluate how dietary supplements, combined with conditioning training, affect athletes’ muscle strength, jump performance, sprint speed, and muscle mass.

In 2025, Bruna Bombassaro and team from the University of Campinas reviewed how dietary factors like caffeine, capsaicin, cinnamon, curcumin, resveratrol, and fatty acids (EPA, DHA, oleic acid) activate brown and beige adipose tissues (BAT) to burn calories via thermogenesis.

In 2025, Li Ding and team from Shanghai University of Sport studied 16 trained men. In a double-blind test, they chewed caffeinated gum (4 mg/kg) or fake gum, then did bench press and back squat lifts. They measured max strength (1RM), power at different weights (25–90%), and muscle activity.

A 2025 meta-analysis by Chen et al. in Nutrients found that caffeine improved attack accuracy, agility, jump height, handgrip strength, and positive plays in volleyball players. The boost was seen with moderate doses before matches.
