Petter Fagerberg
Energy availability (EA) is a scientific concept describing how much energy is available for basic metabolic functions such as reproduction, immunity and skeletal homeostasis. Carefully controlled studies on women have shown pathological effects of EA<30kcal/kg fat free mass (FFM) and this state has been labeled low EA (LEA). Bodybuilding is a sport in which athletes compete to show muscular definition, symmetry and low body fat. The process of contest preparation in bodybuilding includes months of underfeeding, thus increasing the risk of LEA and its negative health consequences...

This study aimed to identify different groups of adolescents who have distinct profiles based upon their perceptions of interpersonal and activity-based dimensions of the sport environment. A sample of 310 adolescents from Eastern Canada (Mage = 14.69 ± 1.60 years; 54.8% girls) completed questionnaires assessing selected interpersonal, activity-based, demographic and sport-specific variables. Using TwoStep Cluster Analysis, we identified three groupings of adolescent sport participants. Consistent with the literature, we labeled these groups 'negative context,' 'positive context,' and 'complex context,' respectively...

This study builds on previous research combining achievement goal orientation from Achievement Goal Theory and motivational regulation from Self-Determination Theory. The aim was to assess the combination of the "what" and "why" of youth sport activity, and how it relates to the need for competence and self-esteem. Achievement goal orientation, specifically task and ego, was employed to represent the "what", whilst intrinsic and external regulation reflected the "why". Based on a sample of 496 youth sports participants, structural equation modeling with a bootstrapping procedure was used to examine whether the indirect relationship between achievement goal orientation and self-esteem was conditional to motivational regulation...

Background: The present study tested Lee et al.'s (2008) model of moral attitudes and cheating behavior in sports in an Italian sample of young tennis players and extended it to predict behavior in actual match play. In the first phase of the study we proposed that moral, competence and status values would predict prosocial and antisocial moral attitudes directly, and indirectly through athletes' goal orientations. In the second phase, we hypothesized that moral attitudes would directly predict actual cheating behavior observed during match play...

Fundamental movement proficiency (FMS) is most successfully acquired during early school years. This cross-sectional study assessed FMS proficiency in Singaporean children at the start of and following 2.5 years of primary school physical education (PE). Participants were 244 children from Primary 1 and 3 levels. Fundamental movement skills (FMS) were assessed with the Test of Gross Motor Development-Second Edition (TGMD-2) that includes locomotor (LOCO) and object control (OC) subtests. Most children were rated "average" and "below average" for LOCO skills but "poor" and "below average" for OC skills without significant gender differences on either subtest or overall FMS proficiency and without FMS mastery...

Australian Rules football (ARF) is a physically demanding sport that can induce high levels of fatigue. Fatigue may be intensified during periods where multiple matches are played with limited recovery time. Combined carbohydrate and protein (CHO+PRO) intake during physical activity may provide performance and recovery benefits. The aim of this study was to investigate whether CHO+PRO ingestion during ARF matches and training sessions throughout a tournament would enhance performance or recovery in comparison to CHO-only ingestion...

Sudden cardiac death (SCD) is the leading cause of mortality in athletes during sport. A variety of mostly hereditary, structural, or electrical cardiac disorders are associated with SCD in young athletes, the majority of which can be identified or suggested by abnormalities on a resting 12-lead electrocardiogram (ECG). Whether used for diagnostic or screening purposes, physicians responsible for the cardiovascular care of athletes should be knowledgeable and competent in ECG interpretation in athletes. However, in most countries a shortage of physician expertise limits wider application of the ECG in the care of the athlete...

Olympic combat sports separate athletes into weight divisions, in an attempt to reduce size, strength, range and/or leverage disparities between competitors. Official weigh-ins are conducted anywhere from 3 and up to 24 h prior to competition ensuring athletes meet weight requirements (i.e. have 'made weight'). Fighters commonly aim to compete in weight divisions lower than their day-to-day weight, achieved via chronic and acute manipulations of body mass (BM). Although these manipulations may impair health and absolute performance, their strategic use can improve competitive success...
