“…After 12 weeks of training 3 times a week, the women in the exercise group (N = 20, median age 79.5, range 76-93) showed 13 -30 % mean increases in isometric quadriceps strength (p <0.01), isometric biceps strength (p <0.01), and lower limb extensor power (p < 0.05) which were not seen in the matched control group (18). In a separate study, of 7 healthy women aged 78 -85, even predominantly aerobic exercise training produced similar improvements in strength and power (14).…”

The loss of strength and power in old age has important implications for health. Even with healthy elderly people, cross-sectional comparisons imply a loss of strength at some 1.5% per year and of power at some 3.5% per year (averaged across the age range 65 to 84). On the other hand, healthy, very elderly people are at least as responsive to strength-training as younger adults. It is important to establish whether elderly people derive functional benefit from training-induced improvements in strength and whether laboratory measurements of strength and power might be used to identify those elderly people most at risk of losing important, everyday functional abilities.

“…There is now greater attention on the need to increase muscle power in older populations (Skelton et al 1994;Bassey et al 1992;Suzuki et al 2001;Bean et al 2002;Malbut et al 1993;Bassey et al 1993;Foldavari et al 1999;Jozsi et al 1999;Earles et al2001;Macaluso et al 2003;Latham et al 2004) and to maintain it in the long term. Long-term programmes, 6-12 months, have been shown to increase muscle strength (Cress et al 1991;Pyka et al 1994), aerobic capacity (Carmeli et al 2003) and function (Shephard 1991).…”

Long-term strength training for community-dwelling people over 75: impact on muscle function, functional ability and life style

et al. 2006

The objective was to determine the impact of a 1-year mixed strength-training programme on muscle function, functional ability, physical activity and life style. Twice-a-week hospital-based exercise classes and a once-a-week home session were conducted. Nineteen healthy community-dwelling training (T) men (76.6 +/- 3.1 years), 19 women (77.5 +/- 4.0 years) and 20 matched controls (C) participated in this study. Training was given with a two multi-gym machines for the lower limbs (Sitting calf and Leg press, TECHNOGYM, Italy) at 60% of the repetition maximum (1 RM) and at home it was with elastic bands. The following were the measurements made: muscle function-maximum isometric strength of the knee extensors (KE) and ankle plantar flexors (PF) measured with a Cybex Norm dynamometer, leg extensor power (LEP) with the Nottingham Power Rig; functional abilities-functional reach, chair rise, bed rise, 6-min walking test, stair climbing, get up and go, one-leg standing; physical activity-aerobic activities over 3 MET intensity (AA3), intensity classes; life-style-mean daily energy expenditure (MDEE). Significant gains in muscle function and functional abilities in both training females and males were observed, but females improved significantly more than males. Males (T + C) showed higher AA3 times than females (T + C) (P = 0.02), with females significantly more involved in light-intensity activities. We observed a 60% increase (t = 2.45) in AA3 time in T, but no increase in C. Trained males increased Class 2 physical activity time by 146% (t = 2.82) and trained females by 16% (t = 2.23). MDEE increased by 10% (t=2.62) in trained males. Our long-term mixed programme can improve muscle function and functional abilities in elderly females and functional abilities in males. It can positively affect the amount of habitual physical activity and the life-style of males and females over 75.
