Babban Sakamako: +17.3 % da +18.2 % Maimaituwa

Masu bincike sun raba matasa 22 (maza da mata) masu horon ƙarfi zuwa ƙungiyoyi biyu – ƙungiyar beta‑alanine (gram 6.4 a rana, n = 12) da placebo na maltodextrin (n = 10).

Rukunin Beta‑Alanine ya samu ci gaba a duka:

• Drop‑sets: jimillar maimaituwa ta ƙaru da kashi 17.3 % (girman tasiri 0.74, p = 0.007).
• Bi‑sets: jimillar maimaituwa ta ƙaru da kashi 18.2 % (girman tasiri 0.98, p < 0.0001).

Me Ya Sa Waɗannan Dabaru? Ka’idar “Acidic Overload”

Mawallafa sun fara da tambaya: me ya sa beta‑alanine ke aiki sosai a wasannin da ake buƙatar ƙarfi mai ɗorewa, amma ba a tabbatar da tasirinsa a horon ƙarfi ba? Sun yi hasashen cewa binciken da suka gabata sun yi amfani da dabaru da ba su kai matakin “acidotic” ba. Drop‑sets da bi‑sets an ƙirƙira su domin tura tsoka cikin gajiya mai zurfi tare da ɗan hutu kaɗan tsakanin saiti.

Yadda aka aiwatar da kowanne dabaru a gwajin:
