Iron deficiency in young basketball players: Is a 100 μg/L ferritin cut-off appropriate for iron supplementation?: Results of a randomized placebo-controlled study.

ABSTRACT:

Background

Iron deficiency (ID) is one of the most common factors that may reduce sports performance, supplementation forms and doses are still not standardized in athletes. Our aim was to assess the iron status of young male basketball players and to study the effect of iron supplementation in a randomized placebo-controlled study.

Hypothesis

We hypothesized that due to the higher iron demand of athletes, the 100 μg/L ferritin cut-off may be appropriate to determine the non-anemic ID.

Methods

During a sports cardiology screening, questionnaires, laboratory tests, electrocardiograms, echocardiography exams, and cardiopulmonary exercise tests were performed. Athletes with ID (ferritin <100 μg/L) were randomized into iron and placebo groups. Ferrous sulfate (containing 100 mg elemental iron [II] and 60 mg ascorbic acid) or placebo (50 mg vitamin C) was administered for 3 months. All exams were repeated after the supplementation period.

Results

We included 65 (age 15.8 ± 1.7 years) basketball players divided into four age groups. Non-anemic ID was observed in 60 (92%) athletes. After supplementation, ferritin levels were higher in the iron group (75.5 ± 25.9 vs. 54.9 ± 10.4 μg/L, p < .01). Ferritin >100 μg/L level was achieved only in 15% of the athletes. There were no differences in performance between the groups (VO₂ max: 53.6 ± 4.3 vs. 54.4 ± 5.7 mL/kg/min, p = .46; peak lactate: 9.1 ± 2.2 vs. 9.1 ± 2.6 mmol/L, p = .90).

Conclusions

As a result of the 3-month iron supplementation, the ferritin levels increased; however, only a small portion of the athletes achieved the target ferritin level, while performance improvement was not detectable.

Project description:BackgroundResearch findings indicate a concerning prevalence of physical inactivity among Saudi females, which has been associated with low physical performance levels. To address this challenge, it is crucial to promote sports participation, particularly in activities such as basketball. However, despite its potential benefits, the specific effects of basketball engagement among Saudi females remain largely unexplored. Therefore, this study investigated the relationship between physical performance and basketball playing among female collegiate players compared to non-basketball players in Saudi Arabia. Also, this study examined the effect of years of playing basketball on the basketball players group's speed, agility, and physical activity levels.MethodsThe participants were divided into two groups: a non-athletic control group of 20 participants (age: 22 ± 2.0 years; weight: 55.6 ± 7.7 kg; height: 157.7 ± 5.5 cm) and a basketball group of 18 participants (age: 20 ± 3.3 years; weight: 60.6 ± 12 kg; height: 163.8 ± 6.3 cm).To examine the relationship between playing basketball and physical performance levels, this study included 38 female participants divided into a non-athletic control group (N = 20) and a basketball group (N = 18). To evaluate physical performance, the 10-Meter Walk Test (10MWT), Modified Agility T-Test (MAT), and International Physical Activity Questionnaire (IPAQ) were used.ResultsBasketball players demonstrated significantly superior performance in the 10-MWT (Mann-Whitney-test = 1.7, p < .05) and MAT (Mann-Whitney-test = 9.6, p < .001) compared to the non-athletic participants. Furthermore, IPAQ scores were significantly correlated with speed and agility (p < 0.05).ConclusionWomen who regularly played basketball exhibited superior physical activity levels and higher physical performance in speed and agility compared to those who were less active. However, no significant differences between the years of playing and any other variables were found. Nevertheless, these findings seek to contribute valuable insights into the potential benefits of basketball playing among Saudi women.

Project description:ImportanceThere is a paucity of data detailing cardiac remodeling in female athletes compared with male athletes. The lack of reference cardiac data for elite female basketball players or female athletes of similar size makes it difficult to differentiate athletic remodeling from potential underlying cardiac disorders in this population of athletes.ObjectiveTo assess cardiac structure and function in elite female basketball players.Design, setting, and participantsThis cross-sectional echocardiographic study included 140 Women's National Basketball Association (WNBA) athletes on active rosters for the 2017 season. The WNBA mandates annual preseason stress echocardiograms for each athlete. The WNBA has partnered with Columbia University to annually perform a review of these studies. Data analysis was performed from June 7, 2017, to October 5, 2017.Main outcomes and measuresEchocardiographic variables included left ventricular (LV) dimensions, wall thickness, mass, prevalence of LV hypertrophy, aortic dimensions, right ventricular (RV) dimension, and right and left atrial size. Linear regression was used to assess the associations between cardiac structure and function with body size quantified as body surface area (BSA) in the primary analysis.ResultsA total of 140 female athletes (mean [SD] age, 26.8 [3.9] years; 105 [75.0%] African American) participated in the study. Mean (SD) athlete height was 183.4 (9.0) cm, and mean (SD) BSA was 2.02 (0.18) m2. Compared with guideline-defined normal values, LV enlargement was present in 36 athletes (26.0%) and 57 athletes (42.2%) had RV enlargement. There was a linear correlation between LV and RV cavity sizes and BSA extending to the uppermost biometrics (LV cavity size: r, 0.48; RV cavity size: r, 0.32; P < .001 for both). Maximal left ventricular wall thickness (LVWT) ranged from 0.6 to 1.4 cm, with 78 athletes (55.7%) having LVWT of 1.0 cm or greater and only 1 athlete (0.7%) having LVWT greater than 1.3 cm. Twenty-three athletes (16.4%) met the criteria for left ventricular hypertrophy (LVH) (>95 g/m2). Eccentric LVH was present in 16 athletes (69.6%), concentric LVH in 7 athletes (30.4%), and concentric remodeling in 27 athletes (19.3%). Mean aortic root diameter was 3.1 cm (95% CI, 3.0-3.2). Only 2 athletes (1.4%) had guideline-defined aortic enlargement compared with a range of 18% to 42% for left and right ventricular and atrial enlargement.Conclusions and relevanceIn this study, increased cardiac dimensions were frequently observed in WNBA athletes. Both BSA and physiologic remodeling affected cardiac morphologic findings. This study may provide a framework to define the range of athletic cardiac remodeling exhibited by elite female basketball players.
