When you want something sugary, try choosing protein.

【Protein Leverage Effect】
•The protein leverage effect suggests that humans prioritize protein intake over other nutrients. If protein needs aren’t met, appetite remains unsatisfied, which can lead to overeating.

•By consuming enough protein, you can reduce cravings for sweets.

【How much should you take?】
Aim for about 1–1.5 g of protein per kg of body weight per day.
Example: If you weigh 60 kg → 60–90 g per day

Recommended foods
•1 egg → 4-6 g
•Greek yogurt (200 g) → 15–20 g
•Chicken breast (100 g) → 22–25 g
•1Canned tuna → 15–20 g

甘いものが食べたい時は、タンパク質を摂る

・プロテインレバレッジ効果
→人間は他の栄養素よりもタンパク質の摂取を優先し、タンパク質必要量を満たすまで食欲が満たされず、食事の過剰摂取につながる。

→プロテインを必要量摂ることで、甘いものが欲しくなる衝動を抑えることができる。

どれくらい摂る？
体重×1〜1.5g（日）のタンパク質を摂る。
60kg→60〜90g

おすすめの食材
・卵1個→6g
・ギリシャヨーグルト（200g）→15-20g
・鶏むね肉100g→22-25g
・ツナ缶→15-20g

Iliopsoas muscle

・The only muscle that connects the upper and lower limbs.

・It is mainly composed of the psoas major and the iliacus (iliopsoas).

・It is a source of power for athletes.
・Compared to non-athletes, athletes show a particularly large difference in the muscle mass of the psoas major.

・The psoas major stabilizes the lumbar spine, but its action varies depending on the curvature of the spine.

「Origin and Insertion」

Psoas major
・Origin: T12–L4 vertebrae
・Insertion: Lesser trochanter of the femur

Iliacus
・Origin: Upper two-thirds of the iliac fossa (ilium)
・Insertion: Lesser trochanter of the femur

Actions
・Hip joint: flexion, abduction, external rotation
・Trunk: stabilization of the pelvis and lumbar spine

「Observation」
・The iliopsoas muscle uses elastic energy stored during its stretch in walking to help flex the hip joint. Therefore, the narrow-step walking pattern often seen in older adults may involve insufficient muscle extension, resulting in a lack of elastic energy and increased strain on the iliopsoas. Simply being mindful of how you walk may have a positive effect on the iliopsoas muscle.

腸腰筋

・主に大腰筋と腸腰筋によって成り立つ。
・上肢と下肢を連結する唯一の筋肉
・アスリートにとってパワーの源になる。
・一般の人に比べてアスリートの方が大腰筋の筋量の差が特に大きい。

起始・停止

大腰筋
第12胸椎〜第4腰椎
小転子

腸骨筋
腸骨上部2/3
小転子

作用
股関節:屈曲、外転、外旋
体幹:骨盤、腰椎の安定

・大腰筋は腰椎を安定させるが、その作用は脊柱の湾曲度によって変化する。

「考察」
・腸腰筋は歩行の時は伸ばされた時の弾性エネルギーも使って、股関節を曲げるので、高齢者に見られる歩幅の狭い歩き方は伸びが足りず弾性エネルギーがなく、腸腰筋に負担がかかるらしい。歩くのを意識するだけでも、腸腰筋に良い影響を与えられそうな気がします。
