Interestingly, this one suggests that low-intensity walking with the addition of blood flow restriction shares acute metabolic characteristics similar to loaded walking with 15% of body mass in adult males.
- Twelve healthy adult males completed five bouts of 3-min treadmill walking at 4.8 km/h with 1-min rest interval under three different conditions:
1) blood flow restriction 2) loaded with 15% of body mass 3) loaded with 15% of body mass with blood flow restriction
- V̇O2 increased by 7% during the loaded+BFR condition compared with BFR or loaded conditions.
- No statistically significant differences in V̇O2 between BFR and loaded were observed.
- Loaded+BFR were associated with lower (−9%) muscle oxygen saturation and deoxygenated hemoglobin compared to the loaded condition.
Comparable Acute Metabolic Responses when Walking with Blood Flow Restriction and Walking with Load Carriage: Implication for Tactical Professionals (open access)
In this one, after primary treatment for ovarian cancer, those who met or exceeded protein intake recommendations for cancer survivors in general (i.e., >1g/kg) had better progression-free survival than those with lower intake levels.
- This study aimed to investigate whether intake of protein and protein food sources following primary treatment for ovarian cancer is associated with recurrence and survival.
- Those who met or exceeded protein intake recommendations for cancer survivors in general (i.e., >1g/kg) were more likely to have better progression-free survival than those with lower intake levels.
In this one, acute exposure to simulated high (~2500m) or very high (~4000m) altitude prior to an OGTT did not appear to influence glucose homeostasis, insulin sensitivity, markers of oxidative stress or inflammation, in males with overweight with a men age of 32 years.
- Previous research has shown that ≤60 min hypoxic exposure improves subsequent glycaemic control, but the optimal level of hypoxia is unknown and data are lacking from individuals with overweight.
- This study tried to examine the short-term effects of different levels of acute hypoxia on glucose tolerance, insulin sensitivity, markers of inflammation and oxidative stress and feasibility in males with overweight, a group predisposed to impaired glucose homeostasis.
The findings of this one suggest that weight loss during a high-intensity exercise program is likely to lead to improved substrate oxidation during exercise.
- This study is a secondary analysis of the “Effects of SIT on substrate oxidation in adults living with and without obesity: i-FLEX study”...
...a clinical trial investigating changes in substrate oxidation and insulin sensitivity following 4 weeks of sprint interval training (SIT) between individuals with and without obesity.
In this one, higher intakes of a pro-inflammatory diet, as assessed by the Energy-adjusted Dietary Inflammatory Index (E-DII) score, was found associated with higher risk of all-cause mortality, and incident cardiovascular disease and cancer.
- The associations with all-cause mortality and incident cardiovascular disease were observed only for diets that were more pro-inflammatory than the global average.
- In contrast, the association with incident cancer was broadly linear.
In this one, a quadriceps-focused exercise program and a hip-focused exercise program provided equivalent effectiveness for improvements in symptoms and function in patients with patellofemoral pain.
- The aim of this study was to assess effectiveness equivalence between a focused ‘Quadriceps Exercise’ protocol and a focused ‘Hip Exercise’ protocol on symptoms and function in patients with patellofemoral pain.
- The exercise interventions lasted for 12 weeks with 3 weekly home-based exercise sessions consisting of three sets of 8–12 repetitions.
In this nationally representative sample of US youths at higher risk for type 2 diabetes due to elevated BMI, risk perception and risk awareness were not found associated with greater engagement in diabetes risk-reducing behaviors.
- Instead, greater diabetes risk perception was associated with more time spent watching TV and fewer days of adequate physical activity, whereas awareness was not associated with reported health behaviors.
- Some health care access barriers, including measures of economic disadvantage, were associated with adverse patterns of health behaviors such as lower levels of physical activity.
