Enterobacter cloacae administration induces hepatic damage and subcutaneous fat accumulation in high-fat diet fed mice.

2018

Accumulating evidence indicates that gut microbiota plays a significant role in obesity, insulin resistance and associated liver disorders. Family Enterobacteriaceae and especially Enterobacter cloacae strain B29 have been previously linked to obesity and hepatic damage. The underlying mechanisms, however, remain unclear. Therefore, we comprehensively examined the effects of E. cloacae subsp. cloacae (ATCC® 13047™) administration on host metabolism of mice fed with high-fat diet (HFD). C57BL/6N mice were randomly divided into HFD control, chow control, and E. cloacae treatment groups. The E. cloacae treatment group received live bacterial cells in PBS intragastrically twice a week, every ot…

The effects of whey protein with or without carbohydrates on resistance training adaptations

2015

Background: Nutrition intake in the context of a resistance training (RT) bout may affect body composition and muscle strength. However, the individual and combined effects of whey protein and carbohydrates on long-term resistance training adaptations are poorly understood. Methods: A four-week preparatory RT period was conducted in previously untrained males to standardize the training background of the subjects. Thereafter, the subjects were randomized into three groups: 30 g of whey proteins (n = 22), isocaloric carbohydrates (maltodextrin, n = 21), or protein + carbohydrates (n = 25). Within these groups, the subjects were further randomized into two whole-body 12-week RT regimens aimin…

Big vs powerful : molecular signalling responses to hypertrophic and power resistance exercise modalities

2015

Introduction: The effects of resistance exercise (RE) loading on molecular signalling proteins, including those involved in protein translation and thus skeletal muscle hypertrophy have been extensively studied. However, there is little research on high power RE loading and molecular signalling proteins, and also on possible relationships between signalling proteins and recovery from RE loading. Methods: 7 young men (31±6 years, 178.9±4cms, 84.6±5 kgs) performed 1 hypertrophy loading session (HYP) (5x10 80% 1RM leg presses (LP)) and 1 power loading session (POW) (10x5 70% 1RM LP), with each session separated by 7 days, in a crossover design, prior and subsequent to 12 weeks of resistance tr…

Velocity-based resistance training: do women need greater velocity loss to maximize adaptations?

2021

Abstract Purpose Men and women typically display different neuromuscular characteristics, force–velocity relationships, and differing strength deficit (upper vs. lower body). Thus, it is not clear how previous recommendations for training with velocity-loss resistance training based on data in men will apply to women. This study examined the inter-sex differences in neuromuscular adaptations using 20% and 40% velocity-loss protocols in back squat and bench press exercises. Methods The present study employed an 8-week intervention (2 × week) comparing 20% vs. 40% velocity-loss resistance training in the back squat and bench press exercises in young men and women (~ 26 years). Maximum strengt…
