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.

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. Image
- 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. Image
- 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. Image
- 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. Image
- 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.
