OS EFEITOS DE EXERCÍCIO DE IMPACTO EM PACIENTES COM OSTEOPOROSE PÓS MENOPAUSA

Introduction: Osteoporosis is a disease characterized by the loss of bone mineral density, which increases the risk of fractures, especially in women. It affects women more due to hormonal changes, and in postmenopause, due to the drop in estrogen levels, which aggravates bone loss. Objective: This was to investigate the effects of impact exercises in patients diagnosed with postmenopausal osteoporosis. Methods: This is an integrative review of the literature, where the PICO strategy was adopted, thus the guiding question of the study was “What are the effects of impact exercises on the bone mineral density of patients with postmenopausal osteoporosis?”. The data search took place between July and August 2024, in the PUBMED, PEDro and LILACS databases, using the descriptors: “impact exercises”, “osteoporosis” and “postmenopause”. A total of 76 articles were found and after applying the eligibility criteria, 8 were used in this review. Results: Impact exercises, such as resistance, aerobic and Pilates exercises, were shown to be effective in improving bone mineral density, muscle strength and balance in postmenopausal women, reducing the risk of fractures and improving quality of life. Conclusion: It is concluded that high-impact exercises offer several benefits for women with osteoporosis in the postmenopausal period, including increased muscle strength, improved balance, lipid profile, calcium absorption, quality of life and bone mineral density.

Self-reported physical activity and fatigue and its associations to anxiety and depression in adult patients with idiopathic inflammatory myopathies: a MIHRA psychological impact and MIHRA exercise and rehabilitation scientific working groups collaboration.

To evaluate self-reported physical activity (PA) levels as well as the relationship between PA, anxiety, depression, quality of life, pain, fatigue, disease activity, and organ damage in patients with idiopathic inflammatory myopathies (IIM). All adult patients registered at the rheumatology clinic at Karolinska University Hospital in Stockholm, Sweden (2019-2022) were eligible to participate. Questionnaires measuring anxiety, depression (HADS), and PA (IPAQ) were provided during yearly check-up or by mail, due to reduced in-person visits amid the Covid-19 pandemic. Additional data was obtained from the Swedish Rheumatology Quality Registry. Of 488 invited patients, 336 agreed to participate, and 246 completed the questionnaires. Median (range) age was 64 (20-88) years, median disease duration five (0.3-61) years and two-thirds were women. Notably, 82% reported moderate/high level of PA. Probable anxiety and depression were experienced by 25% and 14%, respectively. The findings indicated a potential protective effect of PA against depression (OR 0.23, CI 0.06-0.95). Conversely, patients who were physically inactive had poorer mental health, reduced muscle function, increased organ damage, and fatigue. Fatigue demonstrated a progressive link to heightened risks of anxiety (2%, 2-4%) or depression (3%, 1-6%). Most patients with IIM reported being physically active. The study highlights the potential influence of PA on mental health and its role in mitigating risks associated with depression and fatigue among IIM-patients. It also underscores the importance of patient-reported outcomes, and their role in understanding and improving healthcare interventions. Further research is needed to uncover causes and confirm these associations.

Exercise interventions for mitigating the persistent side effects of COVID-19

AbstractFollowing infection with Sars-Cov2, a significant proportion of patients suffer from long-term symptoms afflicting many of the body’s systems. The understanding of these sequelae is still evolving, and as of the present diagnostic techniques and symptom management are still developing to effectively combat the wide variety of long-term symptoms. Many of the long-term symptoms observed following cases of COVID-19 are present in other chronic illnesses, and exercise intervention has been observed as a potent therapy for the alleviation of many of those symptoms. However, the effects of exercise regimens in the treatment of long COVID symptoms are not well documented, and there is little information regarding the nature of those interventions. A review of the available literature was conducted to determine the nature of the post-acute sequelae of COVID-19 (PASC) and identify the potential impact exercise intervention could have in alleviating these sequelae. Overall, intensity and modality of treatment are paramount to the success of a multifaceted exercise intervention to provide the greatest benefits to patients suffering from PASC. There are some limitations to the provision of exercise therapy as an intervention for COVID-19 patients, but nonetheless the benefits of exercise are sufficient that further research is implicated.

Dual Use of Cannabis with Tobacco Is Associated with Increased Sugary Food and Drink Intake in Young People.

Rates of cannabis initiation among teenagers and young adults are increasing. Further, the use of various forms of cannabis (smoked or vaped) with nicotine (dual use) is increasingly common among young people. The health effects of dual use are lesser known, particularly in the context of high-potency cannabis products and across different routes of administration, which is ominous in terms of predicting future health outcomes. There is a long history of cannabis use being associated with decreased activity and increased snacking, both of which could portend an increased risk of metabolic and cardiovascular disease, particularly when these habits begin during formative years. However, modern forms of cannabis may not have these same effects. Here, we assess whether cannabis use alone and dual use of cannabis with nicotine impact dietary and exercise habits in young people. An anonymous, social media-based survey was designed based on the UC San Diego Inhalant Questionnaire and published diet and exercise questionnaires. A total of 457 surveys were completed. Young sole cannabis users represented 29% of responders, 16% were dual users of cannabis and nicotine, and 55% were non-users of either drug. Although the sole use of cannabis was not associated with dietary or activity differences relative to non-users, dual users of cannabis and nicotine reported higher consumption of unhealthy sugars. This novel finding of dual use being associated with increased sugar intake in young people raises concerns for an increased risk of metabolic syndrome and cardiovascular disease in this population.

The association between different impact exercises and osteoporosis: an analysis of data from the Taiwan biobank

Osteoporosis is a prevalent condition marked by reduced bone density and an elevated risk of fractures, especially among postmenopausal women. Exercise plays a crucial role in preventing and managing osteoporosis, with weight-bearing and impact exercises being particularly effective in enhancing bone density and mitigating disease risk. This study investigated the relationship between various types of impact exercises and osteoporosis using data from the Taiwan Biobank (TWB). The study sample comprised 5,123 individuals without osteoporosis and 1,770 individuals with the condition. Student’s t-test and logistic regression analyses were utilized to assess the associations between exercise types and osteoporosis risk. Results indicated that high-impact exercise significantly reduced the likelihood of developing osteoporosis compared to no exercise (odds ratio; OR = 0.573, 95% CI: 0.406–0.810, P = 0.002). Conversely, low-impact exercises did not show a significant overall association with osteoporosis (OR = 1.160, 95% CI: 0.932–1.445, P = 0.184). Stratified analysis by sex revealed that high-impact exercise was protective against osteoporosis in men (OR = 0.391, 95% CI: 0.202–0.755, P = 0.005), but not significantly so in women (OR = 0.671, 95% CI: 0.438–1.027, P = 0.066). These findings suggest that high-impact exercise is associated with a reduced risk of osteoporosis, particularly among Taiwanese men aged 30 to 70.

Optical and acoustic ground effects simulations from terminal defense asteroid disruption via the PI method

Our simulations suggest that Pulverize It (PI), a NASA Phase II NIAC study, is an effective multi-modal approach for planetary defense that can operate in extremely short interdiction modes (with intercepts as short as hours prior to atmospheric entry) as well as long-interdiction time scales with months to years of warning. The basic process is complete disruption of the threat via fragmentation. In scenarios with sufficiently long warning time, the fragment cloud spreads enough to miss Earth, resulting in no ground effects. In “worst-case” scenarios with short warning times (“terminal” scenarios), the fragments (typically <10 m in diameter) will enter Earth’s atmosphere, where their energy is dissipated in a series of ground-level optical pulses and de-correlated shock waves, mitigating any significant damage. We investigate the optical and acoustic ground effects through a set of simulation codes that model the interaction of asteroid fragments with Earth’s atmosphere following terminal threat interception. Even in such cases where fragments enter the atmosphere, our simulations suggest that threats mitigated by PI produce vastly less damage on the ground when compared to an equivalent unfragmented case, yielding optical energy deposition below 200 kJ/m2 and shock wave over-pressures under 3 kPa. Our simulations support the proposition that threats like 2023 PDC, the hypothetical 800 m diameter asteroid from the 2023 Planetary Defense Conference impact exercise, can be effectively mitigated through fragmentation. We find that a terminal defense mitigation scenario that disrupts 2023 PDC into 1 million fragments with an intercept of 60 days before ground impact results in reasonable ground effects with minimal damage.

High Impact Exercise Training Versus Low Impact Exercise Training on Functional Outcome in Subjects with Knee Osteoarthritis: Experimental Study

Background: Exercise or physical exercise is suggested for subjects with arthritic knee to improve their pain andfunctional condition. These therapies, whose success is dependent on a few components, are commonly ignored.Therefore, the proper intensity or load needs to be specified. Depending on the therapy aim exercise intensitymight be high or low.Purpose: This study aims to modulate the patient’s pain and the secondary outcome was to improve functionalityby evaluating high-impact exercise training with low-impact exercise training in subjects with symptomatic kneeOA.Materials and Methods: Subjects with OA Knee were selected based on selection criteria. All subjects were assignedto either of the groups; high-impact exercise and low-impact exercise by odd even randomization method. Thepre-test values for pain and functional outcome are taken using NPRS and WOMAC questionnaire and the samewere recorded for post-test after 8 weeks of intervention. The entire process was performed from November 2022to March 2023.Result: The statistical analysis reveals a lowering in the pain intensity and notable enhancement in functionalityon high-impact exercise training when compared with low-impact exercise training in subjects with arthritic knee.Conclusion: The study’s findings indicate that high-impact exercise training affects subjects with knee osteoarthritisby decreasing pain and improving function.

Risk assessment for asteroid impact threat scenarios

Asteroid impacts can cause a wide range of damage through multiple potential hazards, from localized blast waves or thermal radiation, to tsunami inundation, to global climatic effects. The level of risk posed by these hazards depends not only upon their extent and severity, but also upon the likelihood of the various damage ranges. Some consequences may be more moderate but very likely, while others may be unlikely but catastrophic. Evaluating the risk from these hazards involves substantial uncertainties across all aspects of the problem, including the properties of the asteroid, the specifics of its entry, and the complex high-energy damage physics involved. NASA's Asteroid Threat Assessment Project (ATAP) performs Probabilistic Asteroid Impact Risk (PAIR) assessments that use fast-running entry and hazard models to evaluate millions of impact cases representing the distributions of these many uncertain parameters. This paper presents the current PAIR modeling tools and approaches used for evaluating specific asteroid impact threat cases. We give an overview of the current PAIR model used to support hypothetical impact threat scenarios and discuss some of the key applications of these assessment in supporting planetary defense response and preparedness. We then present the results and key findings from the recent 2023 PDC hypothetical impact exercise as an example of the primary types of risk results and metrics being developed to inform potential mitigation and response decisions. The 2023 PDC scenario represents an impact threat from a large 800-m asteroid with an initial uncertain size range from ∼150 m to 2 km in diameter, spanning sizes that would cause only local damage to sizes that could potentially cause tsunamis or global effects. Results demonstrate key assessment and response challenges for such large impact scenarios, and motivate the need for further modeling and simulation studies to better understand the potential onset and severity of regional and global-scale hazards.

The Impact of Group-based Ergonomic Exercise on Blood Pressure Among Individuals with Hypertension

Introduction: Hypertension is a disease in which a person's blood pressure exceeds normal limits, namely systolic pressure which is above 140 mmHg and diastolic which is above 90mmHg. Exercise that is suitable for people who suffer from hypertension is low impact exercise because it is an exercise with light movements and can be done by anyone, from children to adults, even to the elderly. One of the aerobic exercise for hypertension is ergonomic exercise. Objective: The purpose of this study was to determine The effect of ergonomic exercise on reducing blood pressure in hypertension sufferers. Method: The research design used is correlational quantitative with Wilcoxon Signed-Rank Test. The sampling technique used purposive sampling, with a total sample of 25 people. Result: Based on the results of the Wilcoxon Signed-Rank Test, it was obtained p = 0.000 where p &lt;0.05, which means that there is an effect of ergonomic exercise on systolic and diastolic blood pressure in hypertension sufferers at Posyandu Brotojoyo, Tanjung Rejo Village, Sukun District, Working Area of the Janti Malang Health Center. Conclusion: Based on the results of the Wilcoxon Signed-Rank Test, p = 0.000, where p &lt; 0.05, which means that there is an influence of ergonomic exercise on systolic and diastolic blood pressure in hypertension sufferers at Posyandu Brotojoyo, Tanjung Rejo Village, Sukun District, Janti Malang Health Center Working Area.

Effects of Moderate- to High-Impact Exercise Training on Bone Structure Across the Lifespan: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Moderate- to high-impact exercise improves bone mineral density (BMD) across the lifespan, but its effects on bone structure, which predicts fracture independent of areal BMD, are unclear. This systematic review and meta-analysis investigated effects of impact exercise on volumetric BMD (vBMD) and bone structure. Four databases (PubMed, Embase, SPORTDiscus, Web of Science) were searched up to March 2022 for randomized controlled trials (RCTs) investigating the effects of impact exercise, with ground reaction forces equal to or greater than running, compared with sham or habitual activity, on bone vBMD and structure. Bone variables were measured by quantitative computed tomography or magnetic resonance imaging at the tibia, radius, lumbar spine, and femur. Percentage changes in bone variables were compared among groups using mean differences (MD) and 95% confidence intervals (CI) calculated via random effects meta-analyses. Subgroup analyses were performed in children/adolescents (<18 years), adults (18-50 years), postmenopausal women, and older men. Twenty-eight RCTs (n = 2985) were included. Across all studies, impact exercise improved trabecular vBMD at the distal tibia (MD = 0.54% [95% CI 0.17, 0.90%]), total vBMD at the proximal femur (3.11% [1.07, 5.14%]), and cortical thickness at the mid/proximal radius (1.78% [0.21, 3.36%]). There was no effect on vBMD and bone structure at the distal radius, femoral shaft, or lumbar spine across all studies or in any subgroup. In adults, impact exercise decreased mid/proximal tibia cortical vBMD (-0.20% [-0.24, -0.15%]). In postmenopausal women, impact exercise improved distal tibia trabecular vBMD (0.79% [0.32, 1.25%]). There was no effect on bone parameters in children/adolescents in overall analyses, and there were insufficient studies in older men to perform meta-analyses. Impact exercise may have beneficial effects on bone structure and vBMD at various skeletal sites, but additional high-quality RCTs in different age and sex subgroups are needed to identify optimal exercise protocols for improving bone health across the lifespan. © 2023 The Authors.

Dynapenia and Sarcopenia in Post-COVID-19 Syndrome Hospitalized Patients Are Associated with Severe Reduction in Pulmonary Function.

After hospital discharge, post-COVID-19 syndrome has been observed to be associated with impaired diffusing capacity, respiratory muscle strength, and lung imaging abnormalities, in addition to loss of muscle mass/strength, sarcopenia, and obesity impact exercise tolerance, pulmonary functions, and overall prognosis. However, the relationship between lung function and the coexistence of obesity with low muscle strength and sarcopenia in post-COVID-19 patients remains poorly investigated. Therefore, our aim was to evaluate the association between lung function and the coexistence of obesity with dynapenia and sarcopenia in post-COVID-19 syndrome patients. This cross-sectional study included subjects who were hospitalized due to moderate to severe COVID-19, as confirmed by PCR testing. Subjects who could not be contacted, declined to participate, or died before the follow-up visit were excluded. A total of 711 subjects were evaluated; the mean age was 53.64 ± 13.57 years, 12.4% had normal weight, 12.6% were dynapenic without obesity, 8.3% had sarcopenia, 41.6% had obesity, 21.2% had dynapenic obesity, and 3.8% had sarcopenic obesity. In terms of pulmonary function, the dynapenic subjects showed decreases of -3.45% in FEV1, -12.61 cmH2O in MIP, and -12.85 cmH2O in MEP. On the other hand, the sarcopenic subjects showed decreases of -6.14 cmH2O in MIP and -11.64 cmH2O in MEP. The dynapenic obesity group displayed a reduction of -12.13% in PEF. In post-COVID-19 syndrome, dynapenia and sarcopenia-both with and without obesity-have been associated with lower lung function.

Evidencing the impacts of health research: Insights from trials reported in the 2018 Australian Engagement and Impact Assessment.

While definitions of impact may vary, they often refer to the wider benefits of research evidenced beyond academia. We evaluated case studies featuring randomised trials from the 2018 Engagement and Impact Assessment to better understand how the impacts of health research are evidenced and assessed within Australia. We collated and evaluated 'high' scoring case studies submitted by higher education institutions with a focus on randomised trials across all areas of health research. A qualitative coding system was used for manual content analysis to assess the key characteristics of trials reported, subsequent impacts and the methods used to evidence impacts. A total of 14 case studies were identified citing 35 clinical trials. The majority of interventions were behavioural with a focus on mental, behavioural or neurodevelopmental disorders. Most trials were phase III, focused on the treatment of the indication and were funded by industry. Contribution to clinical guidelines was the highest cited research impact. While there was evidence of researchers seeking to maximise trial impact, case studies lacked details on the role of trial participants and other beneficiaries in generating impact. The impacts of health research can be improved through a better understanding of the priorities and agendas of funders, providing evidence of tangible impact rather than information that is contextual or predictive, and through the early development of impact strategies involving both researchers and beneficiaries. SO WHAT?: Large-scale impact exercises intended for a broad range of disciplines may not be reflective of the depth and scope of health sciences research including trials.

Position Statement: Exercise Guidelines for Osteoporosis Management and Fall Prevention in Osteoporosis Patients.

The effectiveness of exercise for improving osteoporosis and fall prevention in patients diagnosed with osteoporosis or osteopenia has not been fully summarized. The Korean Society for Bone and Mineral Research and the Korean Society of Exercise Physiology has developed exercise guidelines for patients with osteoporosis or osteopenia and provide evidence-based recommendations. A systematic review identified randomized controlled trials (RCT) assessing the effect of resistance, impact, balance, aerobic training, and physical activity in osteoporosis and osteopenia on bone quality, physical performance, quality of life, and fall prevention. PubMed, Embase, KoreaMed, and RISS were searched from January 2000 to August 2022. Ten key questions were established to review the evidence and formulate recommendations. The 50 RCTs reported that even with osteoporosis and osteopenia, resistance and impact training consistently maximized bone strength, improved body strength and balance, and eventually reduced fall incidences. Resistance exercise combining 3 to 10 types of free weight and mechanical exercise of major muscle groups performed with an intensity of 50% to 85% 1-repetition maximum, 5 to 12 repetitions/set, 2 to 3 days/week, for 3 to 12 months is recommended. Impact exercises such as jumping chin-ups with drop landings and jump rope performed 50 jumps/session for at least 6 months with 3 or more days/week are recommended. A multi-component exercise mainly comprised of resistance and impact exercise seems to be an effective strategy to attenuate the risk factors of osteoporosis and osteopenia. The integration of exercise guidelines and individualized exercise plans has significant potential to reduce the morbidity and mortality of osteoporosis.

Individualized Mental Fatigue Does Not Impact Neuromuscular Function and Exercise Performance.

Recent studies have questioned previous empirical evidence that mental fatigue negatively impacts physical performance. The purpose of this study is to investigate the critical role of individual differences in mental fatigue susceptibility by analyzing the neurophysiological and physical responses to an individualized mental fatigue task. In a pre-registered (https://osf.io/xc8nr/), randomized, within-participant design experiment, twenty-two recreational athletes completed a time to failure test at 80% of their peak power output under mental fatigue (individual mental effort) or control (low mental effort). Before and after the cognitive tasks, subjective feeling of mental fatigue, neuromuscular function of the knee extensors, and corticospinal excitability were measured. Sequential Bayesian analysis until it reached strong evidence in favor of the alternative hypothesis (BF10 > 6) or the null hypothesis (BF10 < 1/6) were conducted. The individualized mental effort task resulted in a higher subjective feeling of mental fatigue in the mental fatigue condition: 0.50 (95%CI 0.39 - 0.62) AU compared to control: 0.19 (95%CI 0.06 - 0.339) AU. However, exercise performance was similar in both conditions (control; 410 (95%CI 357 - 463) vs. mental fatigue 422 (95%CI 367 - 477) seconds, BF10 = 0.15). Likewise, mental fatigue did not impair knee extensor maximal force generating capacity (BF10 = 0.928) and did not change the extent of fatigability or its origin after the cycling exercise. There is no evidence that mental fatigue adversely affects neuromuscular function or physical exercise, even if mental fatigue is individualized, computerized tasks seem not to affect physical performance.

High-Intensity Interval Cycling and Running Yield a Similar Myokine and Osteokine Response in Young Adult Females

Background: The differential responses of the myokine irisin, in combination with changes in markers and regulators of bone remodeling to high-intensity interval exercise of high and low impact, were examined in 18 young adult females (22.5 ± 2.7 years). Methods: Participants performed two high-intensity interval exercise trials in random order: running on a treadmill and cycling on a cycle ergometer. Trials consisted of eight 1 min running or cycling intervals at ≥ 90% of maximal heart rate, separated by 1 min passive recovery intervals. Blood samples were collected at rest (pre-exercise) and 5 min, 1 h, and 24 h following each exercise trial. Irisin, osteocalcin, sclerostin, osteoprotegerin (OPG), receptor activator nuclear factor kappa-β ligand (RANKL), and parathyroid hormone (PTH) were analyzed in serum, with post-exercise concentrations being corrected for exercise-induced changes in plasma volume. Results: Irisin was elevated 24 h post-exercise compared to its resting values in both trials (20%, p &lt; 0.05) and was higher after cycling compared to running (exercise mode effect, p &lt; 0.05) with no interaction. Osteocalcin, sclerostin, PTH, and RANKL increased from pre- to 5 min post-exercise (18%, 37%, 83%, and 33%, respectively, p &lt; 0.05), returning to baseline levels in 1 h, with no trial or interaction effects. OPG showed a time effect (p &lt; 0.05), reflecting an overall increase at 5 min and 1 h post-exercise, which was not significant after the Bonferroni adjustment. Conclusions: In young adult females, high-intensity interval exercise induced an immediate response in markers and regulators of bone remodeling and a later response in irisin concentrations, which was independent of the gravitational impact.

Virtual group-based walking intervention for persons with schizophrenia: A pilot randomized controlled trial

Persons with schizophrenia have reduced cardiorespiratory fitness (CRF), a predictor of all-cause mortality. Exercise is effective for improving CRF; however, motivational challenges affecting those with schizophrenia impact exercise engagement and maintenance. Virtual Physical Activity Can Enhance Life (Virtual PACE-Life), a multicomponent walking intervention guided by self-determination theory (SDT), was developed to target CRF in this population while addressing motivational difficulties. Virtual PACE-Life includes live video-delivered group walking sessions, Fitbit activity tracking, recommendations for home-based walking sessions, goal setting, and if-then plans. The present study was a 16-week pilot randomized controlled trial that evaluated the impact of Virtual PACE-Life against Fitbit Alone in a sample of 37 participants with schizophrenia on intermediate targets (competence, autonomy, and relatedness satisfaction, autonomous motivation), proximal outcomes (Fitbit-measured steps/day and minutes spent walking), and the primary outcome (CRF using the 6-min walk test). Blinded research staff completed assessments at baseline, midpoint, posttest, and one-month follow-up. Analysis of covariance and hierarchical linear regression analyses were used to evaluate group differences at each timepoint controlling for baseline. Attendance at Virtual PACE-Life groups was 58% and Fitbit adherence was above 70% in both conditions. Intent-to-treat results indicated greater competence and autonomy satisfaction for Virtual PACE-Life but not in relatedness satisfaction or autonomous motivation. There were no group differences in proximal or primary outcomes during the intervention period. Completer analyses showed improvements in steps/day and autonomous motivation favoring Virtual PACE-Life. Future research is needed to maximize the exercise and CRF benefits of virtual group-based exercise for persons with schizophrenia.

Effects of high impact exercises on physical activity, bone mineral density, body mass index and body fat percentage among osteopenic young females

IntroductionWhile osteopenia was once considered an older disease, it is now commonly seen in young individuals. The low bone density in the young population is alarming, leading to demands to improve physical activity. The study aims to determine the effectiveness of high impact exercise among young females with osteopenia.MethodsA quasi-experimental study was conducted in the out-patient department of Jinnah Sindh medical university among forty-five females aged 18 to 30 years, with osteopenia. The participants were enrolled through convenience and a purposive sampling technique. A training program involving high impact exercise was given for 4 weeks following an initial screening using a DEXA scan. The outcome was measured with the pre- and post-intervention of an exercise program on bone mass density (BMD), body mass index (BMI) and body fat percentage (BFP).ResultsAt the end of the four weeks, BMI, BMD and BFP showed significant improvements (&lt;i&gt;p&lt;/i&gt; &lt; 0.05). The BMD was improved from –1.95 to –1.89. It was found that BMD was significantly associated with age (0.04).ConclusionsOur study confirmed that the bone health of young females needs special attention to avoid osteoporosis in the future. The high impact exercises did show significant improvements through training, but additional studies are required on a larger scale.
