✓Well SupportedIncreasing muscle strength and mass contributes to reducing fall risk and improving functional independence.✓Well SupportedThe 'Lift More' study trained participants, including older women, to safely perform exercises like deadlifts, potentially to the point of lifting their body weight.✓Well SupportedHeavy weightlifting programs can increase cortical thickness of the femoral neck by a net benefit of 133% and the lateral femoral neck cortex by 27%, strengthening the bone.✓Well SupportedStrength training improves functional outcomes including leg and back extensor strength, tandem walk, timed up and go, sit to stand, vertical jump, and reduces kyphosis.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

✓Well Supported

Strength training programs that maintain or improve cortical thickening, increase muscle mass, and improve balance can reduce fall risk.

◐Partially SupportedStrength training in older women can lead to improvements in posture, visible muscle definition, and an increase in height due to better posture.

◐Partially SupportedMaintaining bone mineral density at the hip through strength training is a significant win, even if there isn't a substantial increase.

◐Partially SupportedThe LiftMore study recruited postmenopausal women over 60 with low bone mass (T-score of -1 or lower at spine or hip).

✕Not SupportedCurrent exercise guidelines for osteoporosis are insufficient for adults with osteoporosis.

◐Partially SupportedThe 'Lift More' study's high-intensity resistance and impact training intervention did not cause harm and improved participants' well-being.

◐Partially SupportedLoading bone-growing animals can stimulate bone growth, even with low bone mass.

◐Partially SupportedStabilization or improvement of the Z-score in bone density is considered a win, even if the T-score does not improve.

◐Partially SupportedCompound, weight-bearing free weight exercises like squats and deadlifts are fundamental for improving bone health and functional daily activities.

◐Partially SupportedOlympic lifts are compound movements that engage nearly every muscle in the body, including grip strength.

◐Partially SupportedWeightlifting interventions can improve quality of life for older adults, enabling them to regain independence and participate in activities.

◐Partially SupportedThe LiftMore study involved twice-weekly, 30-minute sessions of high-intensity resistance training (85% 1RM) using compound, free-weight movements.

◐Partially SupportedA low-intensity home program of walking, stretching, and bodyweight exercises was used as a control in the LiftMore study.

◐Partially SupportedWeightlifting training can be done safely and effectively for individuals with osteoporosis and kyphosis, provided proper technique and coaching are employed.

◐Partially SupportedReduced visual input may decrease cortical stimulation, potentially exacerbating or accelerating brain degeneration.

◐Partially SupportedPharmacological interventions like estrogen play a role in managing age-related issues but are not a substitute for strength training.

◐Partially SupportedImprovements in strength and physical capacity, such as lifting body weight, can significantly enhance quality of life for older adults.

◐Partially SupportedGrip strength can decline significantly during periods of reduced training.

◐Partially SupportedImproving functional measures like tandem walk, sit to stand, timed up and go, vertical jump, and grip strength directly reduces the risk of falling.

◐Partially SupportedThe LiftMore study intervention period was shortened from 12 months to 8 months due to PhD project constraints.

◐Partially SupportedBone requires minimal loading, such as one sprint, to stimulate bone cells, not extensive endurance activity.

✕Not SupportedIt is a misconception that it is too late for individuals to improve their physical condition once they reach a certain age.
