A wide, editorial-style flat lay on a warm, matte cream stone surface, shot from slightly above in soft natural morning light. On the left, a ceramic espresso cup in muted terracotta holds dark coffee, with a few roasted coffee beans scattered beside it. In the center, a small wooden board holds three bright red chili peppers, one sliced open to show pale seeds, next to a small pile of coarse red pepper flakes. On the right, a pair of minimalist off-white running shoes with sage green accents rests at an angle, and a slim stopwatch with a clean white face lies in front of them. Three small matte white capsules sit in a neat row at the center of the composition, a quiet nod to the placebo and the active doses. Soft shadows fall to the lower right. A sprig of dried eucalyptus and a folded linen cloth in oatmeal tones add texture at the edges. The palette is warm and restrained: terracotta, chili red, cream, sage, and charcoal brown, with a gentle pop of red as the focal accent. The depth of field is shallow, so the foreground beans are slightly soft and the chilies and capsules stay crisp. The mood is clean, modern, and magazine-like, in the style of a contemporary health and science journal. There is no text, no people, and no logos, and plenty of negative space on the upper left and right edges leaves room for a headline overlay.

Kafein + Capsaicin Mengalahkan Plasebo di Lomba 10K; Capsaicin Sendirian Tidak Berpengaruh

Senyawa cabai ditambah kafein menjadi satu‑satunya kombinasi yang mengalahkan plasebo selama 10 km dalam percobaan crossover terbaru, sementara capsaisin saja tidak memberikan efek. Kafein merupakan faktor utama yang mendasari perbedaan statistik, dan tidak ada bukti sinergi di antara keduanya. Dosis 6 mg/kg setara dengan kira‑kira 450 mg untuk pelari seberat 75 kg, yang tergolong tinggi. Insomnia, kecemasan, sakit kepala, dan detak jantung cepat muncul lebih sering pada kondisi yang mengandung kafein. Berikut temuan utama dari studi yang melibatkan 20 pelari serta rekomendasi siapa yang sebaiknya menghindarinya.
