Abstract: (118 Views)
Background. Optimisation of bone health from exercise interventions and nutritional supplements was recommended.
Objectives. This study aimed to determine whether L-carnitine supplementation combined with interval exercise training influenced bone metabolism markers and muscular strength and power in individuals with overweight and obesity.
Methods. This randomized controlled trial study involved sixty-eight participants in four groups, i.e., control (C, n=17), L-carnitine supplementation alone (Lc, n=17), exercise alone (Ex, n=17) and combined L-carnitine supplement and exercise (LcEx, n=17) groups. The participants in Ex and LcEx groups participated in a 60-minute exercise program per day, 3 times a week, for 12 weeks at 50% heart rate reserved for brisk walking and 40-60% for interval exercise training. The participants in the Lc and LcEx groups consumed 1000 mg of L-carnitine supplement daily. The blood measurements for serum alkaline phosphatase (ALP), total calcium, and serum C-terminal telopeptide of type 1 procollagen (1CTP) were measured at weeks 0 and 12.
Results. The result showed that the LcEx group showed the most remarkable increment in ALP (p<0.05) and total calcium (p<0.05); however, it showed a reduction in serum 1CTP (p=0.003). Regarding muscular performance, the LcEx group (p<0.05) also demonstrated a more significant increase in overall measured parameters of dominant knee extension and flexion peak torque and average power at 60o.s-1 and 300o.s-1 compared to other groups after 12 weeks.
Conclusion. Combining L-carnitine supplementation with brisk walking and interval training can enhance bone formation and muscle performance in people with overweight and obesity.

APPLICABLE REMARKS
APPLICABLE REMARKS
- Current study supports the importance of exercise and L-carnitine supplements in preventing bone loss, either by taking supplements alone, exercising alone, or combining both.
- Interestingly, the combination of L-carnitine and exercise group expressed the highest peak torque and average power at 60o.s-1 and 300o.s-1.
- Therefore, we claim that the active compound in the L carnitine supplement positively affects bone and muscular performance in combination with brisk walking and interval exercise training.
