SUMMARY Weight-bearing physical activity has beneficial effects on bone health across the age spectrum. Physical activities that generate relatively high-intensity loading forces, such as plyometrics, gymnastics, and high-inten- sity resistance training, augment bone mineral accrual in children and adolescents. Further, there is some evidence that exercise-induced gains in bone mass in children are maintained into adulthood, suggesting that physical activity habits during childhood may have… 

Effects of Exercise and Physical Interventions on Bone: Clinical Studies

The clinical relevance of the key determinants of the response of bone to mechanical loading that have evolved from preclinical studies of animals are discussed and novel factors that may influence the skeletal adaptation to exercise in humans are discussed.

Exercise and Bone Mass in Adults

An overview of cross-sectional and longitudinal studies performed to date involving training and bone measurements shows exercise involving high impacts, even a relatively small amount, appears to be the most efficient for enhancing bone mass, except in postmenopausal women.

The link between physical activity and bone strength across the lifespan

This review discusses the central role that physical activity plays in promoting bone health across the lifespan and focuses on the adaptations in bone structure and strength to weight-bearing physical activity.

Impact Exercise for Optimal Bone Health in Growing Children: An Evidence-Based Approach to Exercise Prescription

The influence of impact exercise during growth on bone mass accrual and structure is explored; the available data regarding optimal exercise prescription, including timing and dose, are presented; and the potential for physical activity undertaken during childhood to mediate osteoporosis later in life is explored.

Exercise and Its Effect on Bone Health

Exercise has been shown to help build bone mass in premenarchal girls during the main bone acquisition period of adolescence and in older premenopausal women in their 40's and early 50's and in young women 10-20 years of age that analyzed the contributions of exercise and calcium intake to bone mineral density values, Lloyd and colleagues found that achievable levels of exercise had a favorable effect.

Sports and Metabolic Bone Disease.

The effects of sport on bone metabolism and in particular its relationship with metabolic bone disease are analyzed.

Osteoporosis and Strength Training

The effects of resistance exercise on muscle mass and strength, balance, and agility, in addition to direct skeletal benefits, underscore its importance for osteoporosis, falls, and fracture prevention.

Effects of Weight-Bearing Exercise on Bone Health in Girls: A Meta-Analysis

The findings revealed a small, but significant influence of weight-bearing exercise on BMC and aBMD of the LS in growing girls, and a greater frequency ofweight-bearing activities is related to greater areal bone mineral density of LS ingrowing girls.



Role of physical activity in the development of skeletal mass in children

The data suggest that important increments in skeletal mass may result from physical activity during childhood, and not time spent watching television nor hours of physical education classes were associated either positively or negatively with skeletal mass.

Nutrition, physical activity, and bone health in women.

Weight-bearing physical activity may reduce the risk of osteoporosis in women by augmenting bone mineral during the early adult years and reducing the loss of bone following menopause and the combined effect of physical activity and calcium supplementation on bone mineral needs further investigation.

The effects of region-specific resistance and aerobic exercises on bone mineral density in premenopausal women.

Both resistance and aerobic exercises increase regional bone mass, particularly cortical bonemass, in premenopausal women, and resistance work appears to have a slightly greater effect on cortical bone than aerobics alone.

Prospective Ten‐Month Exercise Intervention in Premenarcheal Girls: Positive Effects on Bone and Lean Mass

Although a large proportion of bone mineral accrual in the premenarcheal skeleton was related to growth, an osteogenic effect was associated with exercise, suggesting that high‐impact, strength building exercise is beneficial for premenARcheal strength, lean mass gains, and bone mineral acquisition.

Effects of resistance and endurance exercise on bone mineral status of young women: A randomized exercise intervention trial

It is demonstrated that 8 months of supervised progressive training in either running or resistance exercise modestly increases lumbar spine mineral in young women.

A two‐year program of aerobics and weight training enhances bone mineral density of young women

It is indicated that over a 2‐year period, a combined regimen of aerobics and weight training has beneficial effects on BMD and fitness parameters in young women, but the addition of daily calcium supplementation does not add significant benefit to the intervention.

A school-based exercise intervention elicits substantial bone health benefits: a 2-year randomized controlled trial in girls.

Three brief sessions of high-impact exercise per week implemented over 2 consecutive years within the elementary school curriculum elicited a substantial bone mineral accrual advantage in pubertal girls.

Bone gain in young adult women.

Gain in bone mass occurs in healthy young women during the third decade of life and physical activity and dietary calcium intake both exert a positive effect on this bone gain, and use of oral contraceptives exerts a further independent positive effect.

Weight training decreases vertebral bone density in premenopausal women: a prospective study.

It is concluded that short term weight training at this frequency and intensity decreases vertebral bone mass in premenopausal women.
