Pedal cadence differentially impacts cerebral blood flow but not a postexercise executive function benefit: Evidence from active and passive exercise (open access) doi.org/10.1152/jn.00572.202…

運動後過剰酸素消費量（EPOC：Excess Postexercise Oxygen Consumption）のススメ。 体脂肪を減らす為には運動して消費カロリーを増加する事。または食事から摂取するカロリーを減らす事。 またはこれを組み合わせる事が一般的な方法です。 基本的には両方を組み合わせる事がオススメなのは誰もが知っている事だと思いますが、やはり運動を取り入れるダイエットをした方が効率良く効果的です。 その一つの要素として運動をすると運動後過剰酸素消費量（EPOC：Excess Postexercise Oxygen Consumption） 通称「アフターバーン」効果という物が得られます。 これは運動後も代謝が高い状態が続き、カロリー消費が続く効果です。 筋トレを行うと軽度な筋繊維の損傷や軽度の炎症を引き起こし、筋繊維の修復や回復に必要なエネルギーを供給する為、体内の代謝プロセスが加速されると言われております。 また運動によって酸素消費量が増えると体内のエネルギー生産も活性化される為、運動後にもエネルギー消費が続きます。 この効果は約24時間続くと言われている為、運動をした方が代謝が良くなり、体脂肪の減少や太りにくい身体作りへの恩恵が受けられると思います。 運動としては高強度の方が効果が得られやすいと言われている為、やはり筋トレがオススメです。

Excited to share our latest publication in the Journal of Strength and Conditioning Research: Sex-Specific Immune Cell Mobilization and Recovery After High-Volume Glycolytic Squat Exercise William J. Kraemer, Mastro AM, Saenz C, Freidenreich DJ, Volk BM, Gomez AL, Fragala MS, Szivak TK, Post EM, Wolf MR, Comstock BA, Häkkinen K, Newton RU, Jeff Volek. This study examined how men and women differ in their acute immune response to a single bout of high-volume glycolytic resistance exercise. Among the key findings: Resistance exercise triggered a rapid and robust immune cell mobilization response. Men showed a greater transient increase in circulating lymphocytes, particularly natural killer cells, shortly after exercise. Women demonstrated a different recovery pattern, including increases in CD4 cells at 60 minutes postexercise. Both sexes showed substantial time-dependent changes in immune cell populations during early recovery. These findings reinforce that resistance exercise is a potent immunological stimulus, while also highlighting that the magnitude and timing of the response are partly sex-specific. Understanding these acute responses may help inform more precise exercise prescription and recovery strategies, while contributing to our broader understanding of the interaction between exercise and immune function.

In this study, fava bean protein supplementation lowered postexercise markers of gut damage without worsening gastrointestinal symptoms during exercise in the heat and was associated with higher whole-body and local sweat rates and thermal sensation.

You will reach tissue saturation (creatine-loaded status) faster if it’s taken postexercise, but once you’re loaded - which can take about a month with a ~5 g/day maintenance dose, then timing relative to training doesn’t matter.

pubmed.ncbi.nlm.nih.gov/2717… "No significant correlations between the acute postexercise rise in any purported anabolic hormone and the change in strength or hypertrophy were found. In congruence with our previous work, acute postexercise systemic hormonal rises are not related to or in any way indicative of RT-mediated gains in muscle mass or strength."

Exercise and Kidney Health (Core Curriculum 2026) Exercise produces predictable renal hemodynamic shifts. Sympathetic activation and RAAS signaling during exertion intentionally lower renal plasma flow and GFR to conserve volume — protective in moderation, harmful when compounded by dehydration or heat stress. Moderate exercise is nephroprotective. Regular aerobic resistance activity improves insulin sensitivity, vascular tone, oxidative balance, and intraglomerular pressure, slowing CKD progression in metabolic disease. Post-endurance creatinine elevation is often physiologic. Increased skeletal muscle breakdown raises serum creatinine without true filtration decline; urine output and cystatin-C help distinguish pseudo-AKI from real injury. Exercise-induced proteinuria reflects transient glomerular stress. Increased filtration fraction and permeability during high-intensity activity allow temporary albumin passage that resolves with recovery. Heat stress markedly amplifies AKI risk. Hyperthermia reduces renal perfusion and promotes oxidative injury; rapid external cooling is the primary intervention in exertional heat stroke. Hydration strategy must be individualized — not maximal. Matching intake to sweat loss preserves renal perfusion, whereas excess hypotonic fluids predispose to exercise-associated hyponatremia. Body-weight tracking is the most practical hydration gauge. A 1-kg postexercise loss approximates 1 L fluid deficit; replacing ~1.5 L/kg restores plasma volume safely. Rhabdomyolysis injures kidneys via myoglobin toxicity. Tubular obstruction, vasoconstriction, and oxidative stress occur with marked CK elevation; early isotonic saline targeting high urine flow is key. NSAIDs impair renal adaptive vasodilation during exertion. Prostaglandin inhibition compromises medullary perfusion, increasing susceptibility to exercise-related AKI. Sports drink selection depends on duration. Water is sufficient for short activity; prolonged exercise benefits from low-carbohydrate (≈3–5%) electrolyte drinks that enhance absorption without slowing gastric emptying. Creatine supplementation can mimic kidney dysfunction. Mild creatinine rise reflects metabolism rather than injury; cystatin-C better estimates true GFR. Exercise remains therapeutic in CKD — including dialysis. Structured programs improve VO₂ capacity, endothelial function, inflammation, and quality of life when supervised. Children with CKD benefit from sport participation. Age-appropriate activity improves strength and cardiovascular health; restrictions should be individualized rather than diagnosis-driven. Recurrent exertional AKI warrants deeper evaluation. Consider hereditary renal hypouricemia, metabolic myopathies, supplement misuse, or inadequate recovery patterns. ajkd.org/article/S0272-6386(…
