“…Subjects performed 3 separate bouts of 10-minute treadmill running at different intensities (65%, 75%, and 85%), in addition to a 30-minute self-paced outdoor run. When the SWA Armband was compared to the IC system, results indicated that the SWA Armband significantly underestimated EE at intensities above 10 MET's, or a running speed of 6 mph (22 Previous studies reveal a lack of consistency when the SWA measures energy expenditure (31,22,39,40,78,43,51,52), suggesting further exploration of the accuracy in the SWA method at varying exercise intensities is warranted. Furthermore, it is possible that additional algorithms modeled for athletes or higher intensity exercise maybe needed to improve the estimation of EE from the SWA technique.…”

“…To date, few studies have examined the accuracy of assessing EE using athletic populations in sports specific environments. This demonstrates a need to identify accurate methodology that can assess EE for athletes while performing sports specific tasks.The SenseWear Mini Armband (Mini) (BodyMedia®, Inc., Pittsburgh, PA), a multi sensor device worn on the upper arm, provides measures of EE during periods of physical activity, and has been examined in adults, children, and clinical patients (31,22,39,40,78,43,51,52). However, few investigations have explored the validity of this instrument using intensities similar to a specific athletic event, or in free-living environments.…”

iv Monitoring an athlete's energy intake and energy expenditure (EE) is an important consideration of nutritional planning for sport conditioning and peak performance. In order to provide appropriate recommendations regarding nutritional requirements and caloric needs, an accurate determination of energy requirements is necessary. By knowing an individual's EE, a coach or trainer may be effectively able to determine training loads and volumes necessary for periodization, and seasonal planning for a particular sport. Purpose: To examine the accuracy of the BodyMedia mini armband, to assess EE in female basketball players during various-intensity game-like conditions. Methods: A cross-sectional correlation design with multiple observations was employed. This investigation required three testing sessions, an orientation session, and 2 experimental trial sections. Trials included a maximal multistage 20-m shuttle run (Trial I) and 30-minute basketball skills session (Trial II). The independent variable for this investigation was EE estimated by the Mini armband. The dependent variable was EE determined by the indirect calorimetry (IC) method. Results: EE assessed with the Mini and EE measured with the IC method was significantly correlated for both Trial I (r= 0.839) and Trial II (r= 0.833). EE calculated by the Mini was significantly underestimated in both Trial I (9.41 ± 26.1 total kcals) and Trial II (56.71 ± 14.1 total kcals). During Trial I the underestimation of EE increased with an increase in test level and intensity. Conclusion: Due to the underestimation of EE by the Mini, the development of exercise specific algorithms to improve the estimation of EE during intermittent exercise in basketball players is warranted. VALIDATION OF THE BODYMEDIA MINI ARMBAND TO ESTIMATE ENERGY EXPENDITURE OF FEMALE BASKETBALL PLAYERS DURING VARIABLE INTENSITY GAME-LIKE CONDITIONS INTRODUCTIONMonitoring an athlete's energy intake and energy expenditure (EE) is an important consideration of nutritional planning for sport conditioning and peak performance. In order to provide appropriate recommendations regarding nutritional requirements and caloric needs, an accurate determination of energy requirements is necessary. By knowing an individuals' EE, a coach or trainer is effectively able to determine training loads, volumes necessary for periodization, and seasonal planning for a particular sport. When caloric intake is not appropriate, changes in body composition may negatively impact overall health and athletic performance (49).Total energy expenditure (TEE) is the amount of energy needed to meet daily physiological demands (48). Monitored across a 24 hour period, TEE includes the following components: 1) basal metabolic rate (BMR), (i.e. the amount of daily energy expended at rest in order to maintain bodily functions) (48); 2) thermic effect of food (i.e. the amount of energy expended during the digestion, absorption, and transportation of nutrients) (48); and 3) physical activity energy expenditure (PAEE) (i.e. the amount...

Low energy availability in male athletes: A systematic review of incidence, associations, and effects

2020

View full text Add to dashboard Cite

The Female Athlete Triad has recently been suggested to be a threat to male athletes. This review aims to examine the evidence, and associated effects, of low energy availability (LEA) in male athletes. A comprehensive search of PubMed and SPORTDiscus was performed. Three RCT and seven CS studies were included that measured energy availability and included well-trained males. Clinical LEA (<30 kcal/kg LBM/d) or subclinical LEA (36 ± 6 kcal/kg LBM/d) was evident within all CS studies, documenting 25% of middle-and long-distance runners and racewalkers and 70% of cyclists with LEA. Two out of three RCTs and three out of seven CS studies reported disrupted endocrine functioning, particularly reduced testosterone levels, in association with LEA. One CS study reported that up to 40% of cyclists with LEA had low BMD. One CS study assessed metabolic health, reporting those with suppressed levels spent more time in a severe energy deficit. This review highlights that LEA appears prevalent across male athletic populations, in particular endurance and weight class athletes, and is a potentially serious threat to bone, endocrine, and metabolic health. Future larger scale longitudinal studies, using appropriate study designs, should be undertaken to confirm these threats.

Assessing Energy Expenditure in Male Endurance Athletes

Abstract: According to our results, the SWA does not provide valid results of TEE and ExEE in endurance athletes because of the underestimation of EE at higher exercise intensities. It seems necessary to develop exercise-specific prediction equations to improve EE measurements in athletes.
