The latest ACSM stretching and flexibility guidelines include: Frequency: Equal to or greater than 2-3 times per week. For many years, the recommendation was that individuals with arthritis should limit activity, and, for the most part, confine that activity to the pool. Consequently, a 60-year-old man who weighs the same as he did at 20 years has an unchanged BMI, but he actually has approximately 20 lbs less muscle and approximately 20 lbs more fat, for a 40-lb undesirable difference in body composition. Figure 11 depicts proper performance of the dumbbell single leg RDL with dumbbells (Supplemental Digital Content 4, https://links.lww.com/FIT/A139; Supplemental Digital Content 5, https://links.lww.com/FIT/A140; RDL Multiple Grips.MOV and RDL Dummbell.MOV depict the RDL performed with a standard pronated and a wide snatch grip and single leg dumbbell RDL variation).

For optimal health in older adults, ACSM's Older Adult Exercise Prescription Guidelines suggest both moderate and vigorous aerobic and strength exercises along with both flexibility and balance training ( 6 ). Loading, repetition, and set number as well as rest periods should reflect the training cycle goals and objectives of the client (1,14). Arthritis; [cited 2011 Jan 13]. With feet between hip and shoulder width and pointing outward slightly, squat down with hips lower than shoulders and grasp the bar with approximately a slightly wider than shoulder width spacing. Stretch to the point of feeling tightness or slight discomfort. Of these, 65% selected the XpressLine program, and 35% chose the traditional protocols. When training at a specific RM load, it is recommended that 2-10% increase in load be applied when the individual can perform the current workload for one to two repetitions over the desired number. Furthermore, relative to fat-free weight, the 10 RM weight loads were just less than 75% of fat-free weight for both men and women. 4. We conducted a 12-wk resistance training program in elderly women [mean age 69 +/- 1.0 (SE) yr] to determine whether increases in muscle strength are associated with changes in cross-sectional . Research has revealed similar percentage increases in muscle strength for beginning men and women strength trainers performing identical programs of resistance exercise (38).
