The use of supplements to enhance performance is popular amongst gym enthusiasts. Citrulline-malate (CM) has been suggested as an effective ergogenic aid via the purported mechanisms of augmented ammonia metabolism, lactate buffering and increased vasodilation. The present investigation aimed to assess whether an 8 g loading dose of CM over 4-days...

Bodybuilders are judged on the subjective visual assessment of their muscular size, proportion, and leanness. This case series tracked four drug-free bodybuilders (3 male) during the off-season, pre-competition and recovery phases. This study aimed to comprehensively profile key biopsychosocial changes occurring pre/post competition in a group of B...

Chronically suppressed energy intake is known to effect resting metabolic rate (RMR) which may have long and short-term negative consequences for health including, future weight gain, impaired immunity and cognitive function (Sundgot-Borgen & Garthe,2011). The chronic suppression of weight/energy intake is also associated with relative energy defic...

Personality Traits of Supplement Users Versus Non-Supplement Users Openness to experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism are agreed upon by many psychologists as the ‘Big 5’ personality traits and are correlated with numerous life outcomes such as career success and life-satisfaction.

Strongmen are characterised by large mass they use to perform feats of strength, the effect this large mass has on the athlete’s health are unknown. The aim of this study was to: characterise a group of strongmen and to compare observed values with established parameters for good health. We measured: resting metabolic rate, body composition, skinfo...

Background: To prepare for competition, bodybuilders employ strategies based around: energy restriction, resistance training, cardiovascular exercise, isometric "posing", and supplementation. Cohorts of professional (PRO) natural bodybuilders offer insights into how these strategies are implemented by elite competitors, and are undocumented in the...

Background Concentrated cherry juice reportedly contains melatonin which, in turn, has been highlighted as an important regulator in initiating sleep. Aim The present investigation aims to clarify whether Night Time Recharge (NTR), a marketed sleep aid containing cherry extract, improves key sleep parameters in young, active adults with mildly poo...

Background Competitive bodybuilders employ a combination of resistance training, cardiovascular exercise, calorie reduction, supplementation regimes and peaking strategies in order to lose fat mass and maintain fat free mass. Although recommendations exist for contest preparation, applied research is limited and data on the contest preparation regi...

Background: Use of supplements to aid performance is common practice amongst recreationally active individuals, including those without a sufficient evidence base. This investigation sought to assess whether acute supplementation with 8 g of citrulline malate (CM) (1.11: 1 ratio) would improve anaerobic performance. Methods: A randomised double...

Abstract Bodybuilders utilize peaking strategies in a bid to fine-tune their aesthetics for competition day. The most prevalent peaking strategies utilized by natural bodybuilders are unreported in the current literature. Eighty-one (M-59, F-22) natural bodybuilders were recruited from competitions during the 2016 and 2017 British Natural Bodybuild...

Background: Citrulline malate (CM) is purported to buffer lactic acid, enhance oxygen delivery, and attenuate muscle soreness. Anaerobic exercise trials with CM have produced conflicting results. Objective: The aim of the current investigation was to test the efficacy of CM on resistance training (RT) with the hypothesis that CM would improve perfo...

Warmer temperatures and increasing interest in high provenance food and drink products are creating new opportunities for cereal growing in northern Europe. Nevertheless, cultivation of oats and barley in these areas for malting and milling remains a challenge, primarily because of the weather, and there are few reports of their nutritional content...

Due to the potential anti-inflammatory properties of fish-derived long chain n-3 fatty acids, it has been suggested that athletes should regularly consume fish oils, although evidence in support of this recommendation is not clear. While fish oils can positively modulate immune function, it remains possible that, due to their high number of double...
