I was thinking about this the other day as my mother, who is turning 60 soon, was asking me about exercise(how often to do it, etc). This study is interesting in the fact that even if someone only has the time or the desire to strength train once a week, even at a mean age of 68 years old, will see an improvement in their "strength, fitness, mobility, general well-being and confidence in performing daily activities." I know many here have parents, or grandparents who may be curious about this so I figured id post it. http://www.ncbi.nlm.nih.gov/pubmed/...nel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum "ISSUE ADDRESSED: Little is known about the effectiveness of once-weekly strength training programs for older adults based in community settings. This pilot study evaluated such a program to assess changes in the functional fitness of participants. METHODS: A pre-test/post-test within subjects study design was used with new participants in the 10-week Staying Active, Staying Strong (SASS) program (all aged 50+ years). The Seniors Fitness Test (SFT) and SF-36 were used to assess functional fitness and health-related quality of life respectively. Perception of physical ability was assessed using a study-specific questionnaire. Pre- and post-test SFT and SF-36 scores were compared using paired t-tests. Frequency of responses was used to describe participant perceptions. RESULTS: 110 evaluation participants (mean age 68.2 years; 85% female), 49% of those who completed the pre-test, also completed the post-test. Evaluation participants significantly improved their strength (assessed using arm curls and sit-to-stand); endurance (two-minute step test); flexibility (sit and reach, back scratch); and agility/dynamic balance (eight-foot up and go). SF-36 physical-functioning domain scores also significantly improved. Most participants reported improved strength, fitness, mobility, general well-being and confidence in performing daily activities. CONCLUSION: Weekly, community-based strength training programs show promise in improving the functional capacity, including the strength, of older adults. More thorough evaluation is now required to confirm these findings."
