Kajian ini bertujuan untuk menentukan kesan latihan unilateral dan bilateral ke atas
kekuatan otot serta defisit bilateral dalam kalangan lelaki terlatih. Model latihan
National Strength and Conditioning Association telah digunakan sebagai kerangka teori
dalam kajian ini. Seramai 30 orang peserta lelaki terlatih dibahagikan secara rawak
kepada tiga kumpulan iaitu dumbbell unilateral (n=10), barbell bilateral (n=10) dan kawalan
(n=10). Kajian ini menggunakan reka bentuk kuasi eksperimen. Ujian pra dan pasca telah
digunakan untuk mengukur kekuatan otot di mana ujian 1- Ulangan Maksima (1-RM) sebelum
dan selepas intervensi dijalankan. Intervensi untuk kumpulan unilateral dan bilateral
dijalankan selama enam minggu. Ujian MANOVA digunakan untuk membandingkan kekuatan otot
(1-RM) dan untuk menentukan kesan intervensi antara kumpulan. Dapatan ujian
MANOVA menunjukkan tiada perbezaan yang signifikan ujian pra di antara tiga kumpulan.
Namun terdapat perbezaan yang signifikan min ujian pasca antara kumpulan. Min ujian pasca
kumpulan kawalan bagi kekuatan unilateral pasca (M = 18.43 kg, SP = 0.13) dan bilateral pasca (M =
18.34 kg, SP = 0.13) adalah lebih rendah daripada min ujian pasca kumpulan unilateral bagi kekuatan
unilateral pasca (M = 25.41 kg, SP = 0.14) dan bilateral pasca (M = 25.41 kg, SP = 0.14) serta min
ujian pasca kumpulan bilateral bagi kekuatan unilateral pasca (M = 24.92 kg, SP = 0.33) dan
bilateral pasca (M = 24.92 kg, SP = 0.33). Hasil ujian MANOVA menunjukkan terdapat perbezaan yang
signifikan dan saiz kesan yang besar terhadap kekuatan otot berdasarkan tiga kumpulan
yang dikaji [F(2, 27) = 530.57, p |
