This study aims to find the effectiveness of different exercise intensities (high-, moderate-, and low-intensity) on the dynamic and static balance of elderly women. A single-blinded factorial design study was conducted in healthy older adults (>65 years) in 12 weeks. The authors have assessed the Forward Reach Test (FRT), Lateral Reach Test (LRT), One Leg Stand (OLS), Tandem Stand Test (TST) in 60 healthy older women at a gym centre, Fit House located in Bukit Rimau, Kuala Lumpur, Malaysia. Participants were randomly assigned to a High-Intensity Training (HIT) group; (n=15) (Mean age 69.60 ± 3.68) who performed four exercises [Leg Press (LP), Leg Extension (LE), Leg Curl (LC), and Calf Raises (CR)] at 80 to 90% of One-Repetition Maximum (1RM); Moderate-Intensity Training (MIT) group (n=15) (Mean age 69.27 ± 3.41) performed at 65 to 75% of 1RM; Low-Intensity Training (LIT) group (n=15) (Mean age 69.27 ± 1.94) performed at 50 to 60% of 1 RM; and a Control Group (CG) (n = 15) (Mean age 68.67 ± 2.38) with no training.Data was collected at pre-test, 4th, 8th, and 12th weeks of intervention. 60 participants were analysed and the main effect of time showed a statistically significant difference in the mean of all variables (all p < 0.001), and also there was a statistically significant interaction between intervention and time on all variables (all p < 0.001). Different levels of intensity on only the lower extremities muscles had a significant effect on the dynamic balance and static balance of the elderly population. After four weeks of training HIT, MIT, and LIT illustrated significant improvement in dynamic balance, as well as static balance.

Resistance training provides many benefits to the older population, and it is considered one of the most effective ways to counter-attack age-related sarcopenia and dynapenia disorders. This article evaluates the impacts of high, moderate, and low training intensities on muscle strength and functional mobility of older adults. A single-blinded factorial design for 12 weeks was conducted among 60 healthy older Malaysian women (>65 years). The authors assessed the Five times Sit to Stand (5STS), the Timed Up and Go test (TUG), and the 6 Minutes Walking Test (6MWT). The participants were randomly divided to the High- Intensity Group (HIT; n=15) (69.60 ± 3.68); Moderate-Intensity Group (MIT; n=15) (69.27 ± 3.41); Low-Intensity Training (LIT; n=15) (69.27 ± 1.94); and Control Group (CG; n=15) (68.67 ± 2.38). In terms of time, there is a statistically noticeable difference in the means of all the variables (p< .001). Moreover, a statistically significant connection between the intervention and time was seen on all the variables (p< .001). However, there was a statistically significant difference between the means of 5STS (P< .001) and TUG (P= .025) in the intervention groups, there was no statistically significant difference observed in 6MWT (P= .90). The results suggested that all of these intensities training are beneficial for improving muscle strength and functional mobility. In addition, the HIT is more effective in improving the 5STS, TUG, and 6MWT, as compared to the MIT, LIT, and CG. These findings revealed that HIT tends to result in greater improvement of muscle strength and mobility.
