Softball Pitching Propulsion and Performance Differences According to Body Fat Percentage
Int J Sports Med DOI: 10.1055/a-1778-4359Softball pitchers with a high body-fat percentage (bf%) can often be successful, despite the heightened risk of injury associated with high bf%. Given the importance of propulsion during pitching, those with high bf% may have an advantage performance-wise. Therefore, the purpose of this study was to examine the differences in ground reaction force (GRF) development between two groups of pitchers: those with a high-fat percentage (≥32 bf%) and a healthy-fat percentage (<32 bf%). Thirty-two female high-school s...

Can a Short-term Daily Oral Administration of Propolis Improve Muscle Fatigue and Recovery?
This study investigated the effect of 1-week oral administration of propolis on muscle fatigue and recovery after performing a fatigue task (total 100 maximal voluntary concentric knee extension repetitions). In this placebo-controlled, double-blind study, 18 young men consumed a formulation with high Brazilian green propolis dose (H-BGP), a formulation with low Brazilian green propolis dose, or a placebo, for 1 week before performing the fatigue task (an interval between each intervention: 1–2 weeks). Maximal voluntary contraction torque, central fati...

Modelling Changes in Bone and Body Composition Over a Season in Elite Male Footballers
This study investigated the change in bone and body composition characteristics of elite football players and recreationally active control participants across the course of a season. Fortysix participants (20 footballers and 26 recreationally active controls) were assessed by dual-energy x-ray absorptiometry and peripheral Quantitative Computed Tomography for a range of bone and body composition characteristics at four points over the course of a competitive season. Multilevel modelling was used to examine changes. Footballers had higher characteristics than cont...

Carbon Plate Shoes Improve Metabolic Power and Performance in Recreational Runners
This study compared metabolic power (MP) and time trial (TT) running performance between Adidas Adizero Adios (AAA) and Nike VaporFly 4% (NVP). Thirty-seven runners completed three laboratory sessions and two field sessions (n=30). After familiarization (visit 1), participants completed eight 6-min treadmill running bouts (four with each shoe, counterbalanced) at their preferred pace, and MP was assessed using indirect calorimetry (visits 2 and 3). During visits 4 and 5, participants completed two outdoor TTs (~3.5 km) in NVP and AAA (counterbalanced)....

Effect of Cardiorespiratory Fitness on Verifying VO2max in Middle-aged and Older Adults
Int J Sports Med DOI: 10.1055/a-1735-3407We investigated the effect of cardiorespiratory fitness (CRF) on the probability of achieving the verification criterion to confirm that VO2max was obtained in a sample of middle-aged to older adults. Data from twelve men and nine women (60.7±8.5 years, VO2max: 34.8±9.4 mL/kg/min) were used for analysis. Participants had their VO2max measured via a maximal graded exercise test and confirmed using a verification bout on a cycle ergometer. Logistic regression was used to evaluate the effect of CRF (VO2max) on th...

Cardiac Rehabilitation Improves Endothelial Function in Coronary Artery Disease Patients
Int J Sports Med DOI: 10.1055/a-1717-1798Exercise-based cardiac rehabilitation may be an effective non-pharmacological intervention for improving endothelial function in coronary artery disease patients. Therefore, this systematic review with meta-analysis aimed to (a) estimate the training-induced effect on endothelial and vascular smooth muscle function, assessed by flow-mediated dilation and nitroglycerin-mediated dilation, respectively, in coronary artery disease patients; and to (b) study the influence of potential trial-level variables (i. e. study and ...

Effect of Exercise Training on Arterial Stiffness in Overweight or Obese Populations
Int J Sports Med DOI: 10.1055/a-1795-2940The purpose was to analyze the effects of exercise training (ET) on arterial stiffness in all-age overweight or obese individuals. Sixty-one trials were included with ET improving flow-mediated dilation (FMD), pulse wave velocity (PWV), and intima-media thickness (IMT). In the subgroup analysis: (i) ET improved FMD in overweight or obese children and adolescents with a large effect size (SMD=0.83, 95% CI 0.42–1.25). PWV was decreased after ET regardless of age. IMT was decreased by ET in participants younger than ...

Effects of a Multicomponent Exercise Training Program on Balance Following Bariatric Surgery
In conclusion, a multicomponent exercise intervention program improves some balance parameters in patients with severe obesity following BS and therefore should be part of post-BS follow-up care as a potential strategy to reduce falls and associated injuries.

Exercise to Lower Postprandial Lipemia: Why, When, What and How
Int J Sports Med DOI: 10.1055/a-1810-5118We review recent findings on the ability of exercise to lower postprandial lipemia (PPL). Specifically, we answer why exercise is important in lowering PPL, when it is most effective to exercise to achieve this, what the preferred exercise is and how exercise reduces PPL. Most findings confirm the power of exercise to lower PPL, which is an independent risk factor for cardiovascular disease. Exercise is most effective when performed on the day preceding a high- or moderate-fat meal. This effect lasts up to approximately two...

Technology and Sleep Quality: Friend or Foe? Let the Exergames Come into Play!
Int J Sports Med DOI: 10.1055/a-1756-5005Low sleep quality is associated with many health problems. Although physical exercise is a nonpharmacological tool that positively impacts sleep quality, there are many barriers (lack of energy, lack of motivation, lack of skills, lack of resources, and fear of injury) for people to adopt an active lifestyle. Exergames are an alternative way of physical exercise that are funnier and more attractive than traditional forms of physical exercise and, therefore, has the potential to increase adherence to a physical exercise prog...

Current Insights into Cellular Senescence and Myotoxicity Induced by Doxorubicin: The Role of Exercise and Growth Factors
Int J Sports Med DOI: 10.1055/a-1797-7622Doxorubicin is an anti-neoplasmic drug that prevents DNA replication but induces senescence and cellular toxicity. Intensive research has focused on strategies to alleviate the doxorubicin-induced skeletal myotoxicity. The aim of the present review is to critically discuss the relevant scientific evidence about the role of exercise and growth factor administration and offer novel insights about newly developed-tools to combat the adverse drug reactions of doxorubicin treatment on skeletal muscle. In the first part, we discu...
