A cyclist in profile, riding a sleek road bike along a quiet coastal road in warm golden-hour light, shot from a low side angle with a shallow depth of field. The rider wears a muted sage-green jersey, black bib shorts, a matte white helmet, and sunglasses. Their face shows calm, focused fatigue, with a faint sheen of sweat on the forearms. One hand is lifted slightly from the handlebars, holding a small, unbranded matte gel packet in soft cream and coral tones, just before opening it. The road curves gently behind them toward a hazy, softly blurred horizon of pale sea and distant hills, with long amber shadows stretching across the asphalt. In the foreground, slightly out of focus, a few gel sachets and a bike bottle rest on a weathered stone wall at the left edge of the frame, adding editorial depth. Fine dust and sunlight glow in the air. The palette is warm and restrained: butter yellow, soft peach, sage, and slate blue, with gentle film-like grain. The composition leaves open negative space in the upper right, a pale gradient sky, for headline overlay. The overall look is a modern, minimalist sports-science magazine photograph: natural, premium, and clean, with realistic textures, cinematic but understated color grading, and no text, logos, or graphics.

炭酸水素ナトリウムジェルを途中で摂取、3時間サイクリング後の12分TTで12 W増加

BY DR. GYMBRO ·

炭酸水素ナトリウムの最適な摂取タイミングはレース前ではなく、レース中かもしれません。11名の訓練されたサイクリストを対象に、炭酸水素ナトリウムと炭水化物を混ぜたジェルを3時間のライド中に摂取させたランダム化クロスオーバー試験が行われました。疲労状態での12分タイムトライアルでは、炭水化物単独に比べて12 Wのパワー増が確認され、胃腸症状の差は見られませんでした。スプリントや2分間の努力では有意な効果はなく、サンプル数が少ない点と製品がMNSTRY提供だった点に留意が必要です。
A cyclist in mid-ride, photographed from a low three-quarter side angle on a quiet country road at golden hour, wearing a matte navy jersey and a white helmet, with soft warm light catching the sweat on his forearms. His expression is calm and focused. The road bends gently through rolling green fields, and the background is softly blurred with creamy bokeh. In the foreground on the left, a styled flat-lay-inspired still life sits on a weathered wooden surface and blends into the scene. It includes two clear water bottles with pale citrus-tinted liquid, a few torn energy gel packets in muted coral and sage, and a small pile of dried apricots and sliced banana. A handful of glossy orange slices adds a bright accent. The shallow depth of field keeps the cyclist sharp in the middle distance while the foreground items are gently softened. The color palette is warm and editorial: soft peach, muted terracotta, sage green, cream, and deep navy. The light is natural and golden, with long, gentle shadows and a slight film-grain texture, like a high-end lifestyle or sports-science magazine spread. The composition follows the rule of thirds, with the cyclist on the right third and open negative space in the upper left, suitable for headline overlay. The mood is energetic yet thoughtful, clean and modern, and the photograph feels authentic rather than staged. There are no logos, no readable text, and no futuristic or sci-fi elements. The overall look is crisp, airy, and refined, in the style of a contemporary health and performance journal cover.

1時間あたり100 gの炭水化物でサイクリストは速くなった――グリコーゲンは関与しなかった

BY COACH RYAN ·

ハードなライドから4時間経過後、1時間あたり100 gの炭水化物を補給したサイクリストは、60 gだけ摂取した人に比べてパワーダウンが小さく抑えられた。驚くべきは、両群の筋肉グリコーゲン量がほぼ同等だったことだ。15名の訓練された男性選手を対象にした無作為・二重盲検クロスオーバー試験は、グリコーゲン以外の要因がパフォーマンス向上に寄与した可能性を示唆している。本稿では実験結果と1 : 0.8のブドウ糖‑果糖プロトコル、実践への応用方法を解説し、対象外となるケースやサンプルが男性のみで小規模だったことの意味合いも検討する。
