1896: influenza, diarrhoea, pneumonia
2006: cardiovascular disease, cancer, accidents
Nowadays, subtle changes in physical activity patterns over the adult lifespan allow most people not engaged on an exercise program to lose a very large proportion of their physical work capacity before they even notice that something is wrong or find that they have crossed a threshold of disability.

In this review, the authors outline the magnitude of the losses in Sarcopenia, their functional consequences, and the efficacy of strength training (ST) as an intervention strategy for delaying, preventing or reversing the effects of sarcopenia. Proposed mechanisms of sarcopenia are outlined and, where information is available, they examine the effects of ST on these potential mechanisms, which include neurogenic factors, anabolic hormones, protein synthesis, gene expression, muscle morphology, and muscle regeneration.
The evidence presented on this review suggests that Strength Training is an effective intervention for improving strength, muscle mass and muscle quality and delaying the onset of physical disability in the elderly.

Methods: Using stable isotope tracer methodologies and mass spectrometric detection, we observed: (a) 76-92-year-old physically frail and 62-74-year-old middle-age adults have lower mixed muscle protein synthetic rates than 20-32-year-old men and women; (b) 2 weeks and 3 months of weightlifting exercise increased the synthetic rate of myosin heavy chain (MHC) and mixed muscle proteins to a similar magnitude in frail, middle-age, and young women and men; (c) Serum myostatin-immunoreactive protein levels were elevated in physically frail women and were inversely correlated with lean mass.
Conslusion: This suggests that the protein synthetic machinery adapts rapidly to increased contractile activity and that the adaptive response(s) are maintained even in frail elders.

OsteoporosisOsteoporosisPURPOSE: To determine the effects of 6 months of whole-body resistive training (RT) on total and regional bone mineral density (BMD) and bone mineral content (BMC) by age and gender in young and older men and women.
METHODS: Younger men (n=10) and women (n=7) aged 20-29 years (25+/-1 years) and older men (n=10) and women (n=10) aged 65-74 years (69+/-1 years) participated in 6 months of progressive whole-body RT. Upper- and lower-body strength was assessed by the one repetition maximum (1RM) test, and total body fat, lean tissue mass, femoral neck BMD, Ward's triangle BMD, greater trochanter BMD, total-body BMD, and L2-L4 spine BMD were determined by dual-energy X-ray absorptiometry before and after 6 months of RT.
CONCLUSION: A 6-month RT program increases muscle mass and improves BMD of the femoral region in young and healthy older men and women as a group, with a trend for this to be greater in young subjects.

OsteoporosisOsteoporosisPURPOSE: This investigation examined the effect of 6 months of high- or low-intensity resistance exercise (REX) on bone mineral density (BMD) and biochemical markers of bone turnover in adults aged 60-83 yr.
METHODS: Sixty-two men and women (68.4 +/- 6 yr) were stratified for strength and randomly assigned to a control (N = 16), low-intensity (N = 24), or high-intensity (N = 22) group. Subjects participated in 6 months of progressive REX training. Subjects trained at either 50% of their one repetition maximum (1-RM) for 13 repetitions (LEX) or 80% of 1-RM for 8 repetitions (HEX) 3 times x wk(-1) for 24 wk. One set each of 12 exercises was performed. 1-RM was measured for eight exercises. BMD was measured for total body, femoral neck, and lumbar spine by dual energy x-ray absorptiometry (DXA).
CONCLUSION: These data indicate high-intensity REX training was successful for improving BMD of the femoral neck in healthy elderly subjects. Also, these data suggest REX increased bone turnover, which over time may lead to further changes in BMD.

FlexibilityFlexibilityPURPOSE: to investigate the effects of aerobic training, strength training and their combination on joint range of motion of inactive older individuals.
METHODS: Thirty-two inactive older men (65 - 78 yr) were assigned to one of four groups (n = 8 per group): control (C), strength training (ST), cardiovascular training (CT), and combination of strength and aerobic training (SA). Subjects in the S, A, and SA trained three times a week for 16 weeks. ST included 10 resistance exercises for the major muscle groups at an intensity of 55 - 80% of 1-RM and CT included walking/jogging at 50 - 80 % of maximal heart rate. Body weight and height, physical activity level and maximal oxygen uptake (VO(2)max) were measured before the training period. Isokinetic (60 and 180 deg x sec(-1)) and concentric strength (1-RM in bench and leg press) were assessed prior to and at the end of the training period. Hip flexion, extension, abduction, and adduction, shoulder extension, flexion, and adduction, knee flexion, elbow flexion and sit-and-reach score were determined before and at 8 and 16 weeks of training.
CONCLUSION: Results indicate that resistance training may be able to increase range of motion of a number of joints of inactive older individuals (increased sit-and-reach performance, elbow flexion, knee flexion, shoulder flexion and extension and hip flexion and extension both mid- and post-training) possibly due to an improvement in muscle strength.

Scientific research from Imperial College of London 2006 shows that people who would be considered slim can have large quantities of fat within them.
% Body fat X BMI Conclusions:
Sumo fighters can show lower levels of cholesterol than a thin person. Bodybuilders has percentage of fat infinitely lower than average population
Tofis can have an unhealthy, even dangerous build-up of fat around their organs,
Low calorie diets without physical activity could be damaging for health
