Abstract: The purpose of this study was to determine the safety and efficacy of consuming a preworkout supplement (SUP) containing caffeine, creatine, β-alanine, amino acids, and B vitamins for 28 days. We hypothesized that little to no changes in kidney and liver clinical blood markers or resting heart rate and blood pressure (BP) would be observed. In addition, we hypothesized that body composition and performance would improve in recreationally active males after 28 days of supplementation. In a double-blind, placebo-controlled study, participants were randomly assigned to ingest one scoop of either the SUP or placebo every day for 28 days, either 20 minutes before exercise or ad libitum on nonexercise days. Resting heart rate and BP, body composition, and fasting blood samples were collected before and after supplementation. Aerobic capacity as well as muscular strength and endurance were also measured. Significant (P < .05) main effects for time were observed for resting heart rate (presupplementation, 67.59 ± 7.90 beats per minute; postsupplementation, 66.18 ± 7.63 beats per minute), systolic BP (presupplementation, 122.41 ± 11.25 mm Hg; postsupplementation, 118.35 ± 11.58 mm Hg), blood urea nitrogen (presupplementation, 13.12 ± 2.55 mg/dL; postsupplementation, 15.24 ± 4.47 mg/dL), aspartate aminotransferase (presupplementation, 34.29 ± 16.48 IU/L; postsupplementation, 24.76 ± 4.71 IU/L), and alanine aminotransferase (presupplementation, 32.76 ± 19.72 IU/L; postsupplementation, 24.88 ± 9.68 IU/L). Significant main effects for time were observed for body fat percentage (presupplementation, 15.55% ± 5.79%; postsupplementation, 14.21% ± 5.38%; P = .004) and fat-free mass (presupplementation, 70.80 ±9.21 kg; postsupplementation, 71.98 ± 9.27 kg; P = .006). A significant decrease in maximal oxygen consumption (presupplementation, 47.28 ± 2.69 mL/kg per minute; postsupplementation, 45.60 ± 2.81 mL/kg per minute) and a significant increase in percentage of oxygen consumption per unit time at which ventilatory threshold occurred (presupplementation, 64.38% ± 6.63%; postsupplementation, 70.63% ± 6.39%) and leg press one-repetition maximum (presupplementation, 218.75 ± 38.43 kg; postsupplementation, 228.75 ± 44.79 kg) were observed in the SUP only. No adverse effects were noted for renal and hepatic clinical blood markers, resting heart rate, or BP. Supplements containing similar ingredients and doses should be safe for ingestion periods lasting up to 28 days in healthy, recreationally trained, college-aged men. [Copyright &y& Elsevier]

Those with intermediate and high-risk prostate cancer typically receive androgen deprivation therapy (ADT) as part of their treatment. ADT often results in extensive side effects including increased risk of cardiometabolic disease. Many ADT side effects can be influenced by exercise, both resistance and aerobic training. Exercise regimes typically combine aerobic and resistance exercise but the appropriate emphasis for achieving the broadest range of therapeutic benefits has yet to be determined. We propose to determine the feasibility of undertaking a larger trial comparing a resistance- vs an aerobic-emphasised exercise intervention in men with prostate cancer undergoing ADT. The trial will also investigate preliminary evidence of difference between arms for cardiometabolic health and quality of life outcomes. This is a 6-month randomised two-armed feasibility trial. Prostate cancer patients undergoing ADT and radiotherapy will be recruited (n = 24) and randomised to either a resistance- or aerobic-emphasised group. Participants will attend twice-weekly supervised individual or small group sessions, with 75% of exercise time in the primary exercise modality. The primary outcome will be feasibility, determined via assessment of recruitment, retention, adherence, safety, and acceptability. Secondary outcomes will include quality of life, body composition, vascular indices, aerobic and muscular fitness and cardiometabolic health blood biomarkers. It is envisaged that the trial will provide valuable information and preliminary difference data that will aid in the design of an efficacious larger trial that will adopt a major and minor emphasis approach to the scheduling of resistance and aerobic exercise.

Sarcopenia refers to the age-related reduction in strength, muscle mass and functionality which increases the risk for falls, injuries and fractures. Sarcopenia is associated with other age-related conditions such as osteoporosis, frailty and cachexia. Identifying treatments to overcome sarcopenia and associated conditions is important from a global health perspective. There is evidence that creatine monohydrate supplementation, primarily when combined with resistance training, has favorable effects on indices of aging muscle and bone. These musculoskeletal benefits provide some rationale for creatine being a potential intervention for treating frailty and cachexia. The purposes of this narrative review are to update the collective body of research pertaining to the effects of creatine supplementation on indices of aging muscle and bone (including bone turnover markers) and present possible justification and rationale for its utilization in the treatment of frailty and cachexia in older adults. • The combination of creatine supplementation and resistance training increases lean mass and muscle strength in aging adults. • Creatine supplementation decreases measures of bone catabolism which may help explain some of the preliminary increases in bone area and strength. • Creatine supplementation poses no adverse effect on kidney or liver function. • Creatine supplementation as the potential to be an effective intervention for treating frailty and cachexia.

KNEE osteoarthritis , *REGULATION of body weight , *WEIGHT loss , *EXERCISE therapy , *CONTRAST effect , *DISEASE progression - Abstract
Being overweight or obese is a primary modifiable risk factor that exacerbates disease progression and mobility disability in older knee osteoarthritis (OA) patients. Lifestyle interventions combining exercise with dietary weight loss (EX+DWL) yield meaningful improvements in mobility and weight loss that are superior to EX or DWL alone. Unfortunately, community access to practical, sustainable weight management interventions remains limited and places knee OA patients at increased risk of mobility disability. The Collaborative Lifestyle Intervention Program in Knee Osteoarthritis patients (CLIP-OA), was a two-arm, 18 month randomized-controlled, comparative effectiveness trial designed to contrast the effects of an evidence-based, theory-driven EX+DWL intervention, personalized to patient needs and delivered by our community partners, with those of the Arthritis Foundation's Walk With Ease (WWE) standard of care self-management program in the treatment of knee OA patients with overweight or obesity. The primary outcome of the CLIP-OA trial was mobility performance assessed using the 400-m walk test (400MWT). Secondary outcomes included weight loss, pain, select quality of life and social cognitive variables, and cost-effectiveness of intervention delivery. Findings from the CLIP-OA trial will determine the comparative and cost-effectiveness of the EX+DWL and WWE interventions on key clinical outcomes and has the potential to offer a sustainable medium for intervention delivery that can promote widely accessible weight management among knee OA patients with overweight or obesity. Trial Registration: NCT02835326. [ABSTRACT FROM AUTHOR]

COLON cancer , *PHYSICAL activity , *CANCER relapse , *EXTRACELLULAR vesicles , *CANCER invasiveness - Abstract
[Display omitted] • Epidemiological studies indicate that physical activity/exercise has a protective effect against colon cancer progression. • Changes in shear pressure, systemic milieu, extracellular vesicles, and immune system by exercise may impact colon cancer. • Research into mechanisms will enhance development of targeted exercise prescription for patients with colon cancer. Numerous epidemiological studies indicate that physical activity has a protective effect against colon cancer development and progression. Further, the relevant biological mechanisms where physical activity or exercise may improve survival have also been initially examined. In this review, we provide an overview of the epidemiological evidence to date which comprises 16 cohort studies of the effects of physical activity on colon cancer outcomes including cancer recurrence, cancer-specific and overall survival. Moreover, we present four potential mechanisms involving shear pressure, systemic milieu alteration, extracellular vesicles, and immune function by which physical activity and exercise may favorably impact colon cancer. Research currently in progress will provide definitive evidence of survival benefits resulting from exercise and future work will help clarify the role of targeted exercise and the relevant mechanisms involved.
