PENINGKATAN KEPADATAN TULANG AKIBAT LATIHAN RENANG AEROBIK DAN ANAEROBIK
Athar
Abstract: This study is meant to
prove that aerobic and anaerobic exercises can influence bone density based on
bone mineral density (Sonic 1200). Thirty white rats (Rattus norvegicus of
Wistar strain) are used for this study. They are randomly selected from their
population and allocated for a randomized posttest group design only. They are
males, 3 months of age, and 190-210 grams. They are divided into three 10
groups by ordinal pairing method, which are randomly allocated for aerobic
swimming exercise (13 minutes), anaerobic swimming exercise (1 minute exercise
plus 3 minutes relaxation, for 4 sets), and control. Exercises are conducted in
3 times a week for 8 weeks. Data are processed statistically and presented
descriptively with variance analysis and LSD. The result shows that the Mean’s
±
SD’s of BMD’s of aerobic, anaerobic exercise and control are 1510
± 9,
1492 ±
12 m/sec respectively. BMD of aerobic exercise is higher than the control group
(p<0.01). BMD of anaerobic exercise is also higher than the control group
(p<0.01). BMD of aerobic exercise is higher than the anaerobic one (p,0.01).
