Retrospective Analysis of Protein- and Carbohydrate-Focused Diets Combined with Exercise on Metabolic Syndrome Prevalence in Overweight and Obese Women

BACKGROUND To examine the effect of protein-focused (PRO, 1.14 g/kg/day) and carbohydrate-focused (CHO, ∼2.2 g/kg/day) diets (∼1600 kcals) combined with 10 weeks of circuit exercise training in sedentary overweight/obese women (N = 661, age 46 ± 11 years) on metabolic syndrome (MetS). METHODS We retrospectively analyzed eight exercise training studies performed from 2002-2014. Primary (MetS), secondary (MetS z-scores and individual MetS components), and tertiary outcomes [body mass index (BMI) by WHO cut points] were analyzed using chi-square, GLM, and McNemars tests. RESULTS Both groups experienced significant weight loss, improvements in fitness, and reductions in MetS prevalence from baseline to follow-up (PRO: 49% to 42%, CHO: 42% to 36%, both P < 0.01). MetS z-score improvement (∼66.5%) was similar for both groups with no significant between-group differences noted. There were also no significant differences for individual component features between groups for the following: waist circumference (-0.28 ± 0.02 vs. -0.28 ± 0.025 cm, P = 0.97), glucose (-0.07 ± 0.03 vs. -0.08 ± 0.04 mM, P = 0.87), triglycerides (-0.16 ± 0.04 vs. -0.09 ± 0.04 mM, P = 0.20), high-density lipoprotein cholesterol (-0.21 ± 0.03 vs. -0.19 ± 0.04 mM, P = 0.68), and systolic BP (-0.16 ± 0.4 vs. -0.24 ± 0.05 mmHg, P = 0.26). Diastolic BP showed a minor advantage for the PRO group (-0.14 ± 0.05 vs. -0.30 ± 0.05 mmHg P = 0.02). When stratified by BMI, those with morbid obesity did not show a significant improvement in MetS while following a PRO-focused diet; however, caution is warranted given the exploratory nature of this analysis. CONCLUSIONS Our findings suggest that a low-moderate calorie diet partitioned for CHO and PRO preference is equally effective when combined with a structured exercise program for reducing the prevalence of MetS prevalence in overweight/obese women.

Powdered tart cherry supplementation surrounding a single bout of intense resistance exercise demonstrates potential attenuation of recovery strength decrement with no definitive oxidative or inflammatory effect

Background Consumption of tart cherry juice has been reported to increase subsequent resistance exercise performance by reducing inflammation and oxidative stress that cause secondary muscle damage following initial bouts of resistance exercise. The purpose of this study was to determine if consumption of a powdered form of tart cherries derived from tart cherry skins (CherryPURE Freeze Dried Tart Cherry Powder) prior to and following intense resistance exercise increases subsequent performance while attenuating markers of inflammation and oxidative stress.

Short-term powdered tart cherry supplementation encircling an acute endurance challenge potentially increases running performance and attenuates post-race markers of inflammation.

Background Consumption of tart cherry juice has been reported to increase endurance aerobic performance and attenuate perceptions of muscle soreness by reducing inflammation and oxidative stress that cause secondary muscle damage following endurance exercise. The purpose of this study was to determine if consumption of a powdered form of tart cherries derived from tart cherry skins (CherryPURE Freeze Dried Tart Cherry Powder) prior to and following strenuous endurance exercise increases performance while attenuating markers of inflammation and oxidative stress.

Effects of ingesting a pre-workout supplement with and without synephrine on cognitive function, perceptions of readiness to perform, and exercise performance

Background A number of nutritional strategies have been developed to optimize nutrient delivery prior to exercise. As a result, a number of pre-workout supplements have been developed to increase energy availability, promote vasodilation, and/ or positively affect exercise capacity. The purpose of this study was to examine the acute effects of ingesting a preworkout dietary supplement with and without synephrine on cognitive function, perceptions of readiness to perform, and exercise performance.

Powdered tart cherry supplementation moderates post-exercise immunosuppression, total cholesterol, and antioxidant status with no effect on performance recovery following an acute bout of intense lower body resistance exercise.

Background Consumption of tart cherry juice has been reported to effectively reduce inflammation, muscle damage, and muscle soreness following bouts of exercise. The purpose of this study was to determine if consumption of a powdered form of tart cherries derived from tart cherry skins prior to and following intense resistance exercise promotes similar positive results as seen with tart cherry juice consumption.

Powdered tart cherry supplementation effectively reduces markers of catabolism and perceptions of muscle soreness following an acute bout of intense endurance exercise

Background Consumption of tart cherry juice has been reported to effectively reduce inflammation, muscle damage, and muscle soreness following bouts of exercise. The purpose of this study was to determine if consumption of a powdered form of tart cherries derived from tart cherry skins prior to and following intense endurance exercise promotes similar positive results as seen with tart cherry juice consumption.

Powdered tart cherry supplementation mitigates the post-exercise immune response with reduction in total antioxidant status and serum triglyceride levels following an acute bout of intense endurance exercise

Background Consumption of tart cherry juice has been reported to effectively reduce inflammation, muscle damage, and muscle soreness following bouts of exercise. The purpose of this study was to determine if consumption of a powdered form of tart cherries derived from tart cherry skins prior to and following intense endurance exercise promotes similar positive results as seen with tart cherry juice consumption.

Thermogenic and hemodynamic effects of ingesting a pre-workout supplement with and without synephrine

Background A number of nutritional strategies have been developed to optimize nutrient delivery prior to exercise. As a result, a number of pre-workout supplements have been developed to increase energy availability, promote vasodilation, and/ or positively affect exercise capacity. The purpose of this study was to examine the acute effects of ingesting a preworkout dietary supplement with and without synephrine on energy metabolism and cardiovascular hemodynamics. Methods
