Accumulation of dysfunctional and damaged cellular proteins and organelles occurs during aging, resulting in a disruption of cellular homeostasis and progressive degen-eration and increases the risk of cell death. Moderating the accrual of these defunct components is likely a key in the promotion of longevity. While exercise is known to promote hea...
Diet and exercise will help you live longer" is a well-known meme. While often taken for granted, its foundations span back to our evolutionary environment and its effects extend into our intracellular environment. Humans evolved under conditions of high physical activity and periodic privation which shaped our genes. During these times of energeti...
Autophagy is an evolutionary conserved cellular degradation system that underlies the positive effects of exercise. Currently, few human data exist investigating the autophagic response to exercise including the response to high-intensity interval training (HIIT), response in divergent tissues, and if sex differences exist. The purpose of this stud...
Military activities often involve high-intensity exercise that can disrupt antioxidant capacity. We investigated the effects of oregano supplementation on muscle damage, oxidative stress, and plasma antioxidant markers of soldiers performing the army combat readiness test (ACRT). Twenty-four healthy male soldiers (age: 24 ± 3 years, height: 167 ± 1...
Background
Exercise-induced muscle damage (EIMD) commonly occurs following intense resistance exercise and is associated with decrements in exercise performance and delayed muscle recovery. Thus, practical methods to attenuate EIMD would prove useful to both training and athletic populations. Omega-3 (n-3) supplementation has been shown to mitigate...
Context
Numerous chronic conditions including obesity exhibit autophagic dysfunction. Association of immune cell autophagic marker regulation by body fat percentage (%BF) is unknown.
Objective
Investigate autophagy activity in peripheral blood mononuclear cells (PBMCs) of adults with distinct %BFs and obesity-related circulating inflammatory marke...
Fish oils (FOs) are rich in omega-3 long-chain polyunsaturated fatty acids, which have been purported to enhance recovery of muscular performance and reduce soreness post-exercise. However, the most effective FO dose for optimizing recovery remains unclear. The purpose of this investigation was to examine the effect of FO supplementation dosing on...
International Journal of Exercise Science 13(1): 714-722, 2020. The purpose of this study was to compare the muscle activation of the scapula, leg, and trunk among the front squat (FS), overhead squat (OHS), back extension (BE) and plank (PL). Seven recreationally trained men (age: 28 ± 3.6 years, body mass: 92 ± 26.1 kg, height: 175 ± 5.3 cm, 3-RM...
Objective:
Examine the physical fitness of career firefighters and compare their results to normative data and suggested standards for their profession.
Methods:
Eighty firefighters completed a body composition analysis, maximal aerobic capacity (VO2max) test, and fitness testing battery, with results compared with normative value tables. Maxima...
Background: Aerobic exercise has been shown to impart anti-inflammatory effects partly through increased secretion of interleukin-6 (IL-6). Still unclear, however, is whether resistance exercise (RE) also enhances IL-6 secretion. Objective: The present study aimed to examine the effect of RE, performed at varying volume loads (VL), on plasma IL-6....
Autophagy is an evolutionary conserved cellular degradation system implicated in maintaining health and promoting longevity. Few human data exist investigating the autophagic response to exercise; however, acute moderate-intensity, continuous exercise (MICT) has been shown to stimulate autophagy in skeletal muscle. Presently, it is unknown whether...
This study investigated the effect of branched-chain amino acid (BCAA) supplementation on recovery from eccentric exercise. Twenty males ingested either a BCAA supplement or placebo (PLCB) prior to and following eccentric exercise. Creatine kinase (CK), vertical jump (VJ), maximal voluntary isometric contraction (MVIC), jump squat (JS) and perceive...
Various post-exercise strategies have been proposed to accelerate recovery during periods of training. However, the effects of water immersion (WI) temperature on recovery amid multiple daily exercise bouts are not well investigated.
Purpose:
To evaluate the effects of cold and warm water immersion temperatures between acute exercise bouts vs. no...
CrossFit is a physically and metabolically-demanding training mode increasing in popularity among recreational athletes. Presently, however, scarce evidence is available documenting its energetic profile. This study investigated the metabolic characteristics of a CrossFit training bout as measured by expired gases and blood lactate. Eleven females...
This study aimed to evaluate the impact of 6 weeks of BA Supplementation on anaerobic performance measures in collegiate rugby players
Substantial research has been completed examining the impact of carbohydrate (CHO) intake on endurance exercise, whereas its role in resistance-based exercise performance, adaptation and cell signalling has yet to be fully characterised. This empirical shortcoming has precluded the ability to establish specific CHO recommendations for resistance ex...
CrossFit is a metabolically demanding strength and conditioning method which performance may benefit from a carbohydrate (CHO)-rich diet. This study investigated the effect of three consecutive days of high CHO intake on CrossFit performance and corresponding metabolically -related variables in strength trained individuals. Eighteen subjects with a...

A NUMBER OF KEY CONSIDERATIONS EXIST REGARDING PROTEIN, INCLUDING OVERT REQUIREMENTS, QUALITY, AND DOSING. IN ADDITION, ATHLETES AND RESEARCHERS HAVE CLOSELY EXAMINED THE IMPACT OF PROTEIN AND NUTRIENT TIMING ON ACUTE AND PROLONGED ADAPTATIONS TO DIFFERENT TYPES OF EXERCISE WITH MIXED RESULTS. THE PATTERN OF MEAL AND PROTEIN CONSUMPTION SEEMS TO EX...
PROTEIN, A KEY MACRONUTRIENT, IS NEEDED BY THE BODY TO REPAIR AND BUILD NEW CELLULAR STRUCTURES. EXERCISING INDIVIDUALS PARTICIPATING IN BOTH AEROBIC AND ANAEROBIC ACTIVITIES REQUIRE GREATER AMOUNTS OF PROTEIN (1.2–1.6 G·KG−1·D−1) IN THEIR DIET. PROTEIN QUALITY IS EVALUATED PRIMARILY BY ESSENTIAL AMINO ACID CONTENT (8–12 G) AND DIGESTIBILITY CORREC...
Questions
Question (1)
I am using a combination of 8 hours of electrical pulse stimulation and starvation and seeing an increase in LC3II and p62 in both bafilomycin-treated and non-treated cells. Though there is a greater increase in both proteins in bafilomycin-treated cells, I would have expected they would decrease in non-treated cells. Should I be seeing this response?
