Background This is the first study analysing levels of physical activity in a sample of quarantined adults with chronic conditions. The aim of this study was to compare moderate-intensity and vigorous-intensity physical activity levels in Spanish adults with chronic conditions before and during COVID-19 quarantine. Methods A cross-sectional online survey was administered during the COVID-19 quarantine in Spain. A total of 163 participants with chronic conditions (113 females and 47 males; age range 18-64 years) completed the survey. A total of 26 chronic conditions were included. Participants self-reported average minutes/day of moderate and vigorous physical activity before and during quarantine. Differences in moderate-intensity physical activity and vigorous-intensity physical activity levels before and during COVID-19 quarantine (overall, by gender, by age, by number of chronic conditions and by each chronic condition) were assessed by Wilcoxon signed-rank test. Results During COVID-19 quarantine, there was a significant decrease of moderate-intensity physical activity in Spanish people with chronic conditions (in both males and females, in those aged 18-24, 25-34, 35-44 and 55-64 years, in those with multimorbidity, in those with one/two chronic condition/s, and in those diagnosed with asthma/hypercholesterolemia/chronic skin disease/hemorrhoids). Also, there was a significant decrease of vigorous-intensity physical activity in Spanish males with chronic conditions and in those with multimorbidity. Conclusions These results should be considered to develop effective strategies of physical activity promotion targeting these specific groups when new quarantine or restriction measures are implemented, in order to avoid new significant decreases of physical activity in these vulnerable populations.
The aim of this study was to confirm that vitamin D supplementation of young soccer players during eight-week high-intensity training would have a significant effect on their motion activity. The subjects were divided into two groups: the experimental one, which was supplemented with vitamin D (SG, n = 20), and the placebo group (PG, n = 16), which was not supplemented with vitamin D. All the players were subjected to the same soccer training, described as High-Intensity Interval Training (HIIT). The data of the vitamin D status, time motion parameters and heart rate were collected just before and after the intervention. A significant increase in 25(OH)D concentration (119%) was observed in the supplemented group, while the non-supplemented group showed a decrease of 8.4%. Based on the obtained results, it was found that physical activity indicators in the players were significantly improved during small-sided games at the last stage of the experiment. However, taking into account the effect of supplementation with vitamin D, there were no statistically significant differences between the placebo and the supplemented groups; thus, the effect size of the conducted experiment was trivial.
It is important to study differences in body composition, physical fitness and lifestyle behaviours between university students from different countries to develop country-specific recommendations on health promotion to provide to students when transitioning to university. The present study aimed to analyse differences in body composition, physical fitness and lifestyle behaviours between Polish and Spanish students of Sports Sciences. One-hundred-and-eighty-six male students participated (81 from Poland and 105 from Spain). Polish males were on average 21.5 ± 1.9 yrs old and Spanish males 21.5 ± 2.5. The body composition variables measured were body weight (kg), fat-free mass (FFM, kg and %), fat mass (FM, kg and %), total body water (TBW, kg and %), basal metabolic rate (BMR, kcal), body mass index (BMI, kg/m2), fat-free mass index (FFMI, kg/m2) and fat mass index (FMI, kg/m2). The physical fitness variables measured were squat jump (SJ, height in cm, power in watts and w/kg), countermovement jump (CMJ, height in cm, power in watts and w/kg), running speed (10, 20 and 30 m (time in s)), and progressive aerobic cardiovascular endurance run (PACER, stage, final speed in km/h, distance in m, VO2max in mL/kg/min). Lifestyle variables measured were vigorous physical activity (VPA, days/week, min/week), moderate physical activity (MPA, days/week, min/week), walking (days/week, min/week), sitting (min/week), meals/day, vegetables/day, fruits/day, seafood/week, dairy products/week, sweets, chips, fast food/week, litres of liquid/day, litres of sugary drinks/day, alcohol/week and cigarettes/day. In comparison to Spanish students, Polish students had greater FFM (kg), greater TBW (kg), higher BMR, greater power in SJ, greater height and power in CMJ, lower times in running speed tests (10 and 20 m) and greater consumption of vegetables and liquids. In comparison to Polish students, Spanish students participated in more physical activity, and consumed more seafood, more dairy products, less sugary drinks, less alcohol and less tobacco. VPA and consumption of vegetables and liquids had positive influences on body composition and physical fitness. According to these results, universities should promote a healthy lifestyle in order to improve body composition and physical fitness in male students studying sport science. In the cases of Spain and Poland, special attention should be paid to the weak points detected in this study. This would be useful for avoiding future risk of diseases such as obesity or diabetes.
The main purpose of this research was to demonstrate the changes in 25(OH)D concentration, bone resorption markers, and physical fitness along the one-year training season in young soccer players. A total of 24 young soccer players (age: 17.2 ± 1.16 years, mass: 70.2 ± 5.84, height: 179.1 ± 4.26 cm) were tested at four different time points across one year (T1—September 2019; T2—December 2019; T3—May 2020; T4—August 2020). After T2 (during COVID-19 lockdown), players were divided into a supplemented (GS) group and a placebo group (GP). Variables such as 25(OH)D, calcium (Ca), phosphorus (P), parathyroid hormone (PTH), aerobic capacity, speed, and explosive power were measured. Analyses performed for all participants indicated significant changes in all selected blood markers and running speed. The highest values in 25(OH)D were noted during summertime in T1 and T4. After individuals were split into two groups, a two-factorial ANOVA demonstrated a significant time interaction for 25(OH)D, Ca, P, PTH, 30 m sprint, and counter-movement jump. Significant time x group effect was calculated for aerobic capacity. This study confirmed that 25(OH)D concentration varies between four seasons, with the greatest decreases in the low sunlight periods. Vitamin D supplementation did not cause a preventive and long-lasting effect of increasing the 25(OH)D concentration in the young soccer players.
Background The objective was to compare levels of physical activity (PA) in a large sample of Spanish people with diabetes with and without cataracts. To our knowledge, this is the first study comparing PA levels in people with diabetes with and without cataracts in a large representative sample. Methods Cross-sectional data from the Spanish National Health Survey 2017 were analyzed (n = 1014 people with diabetes; 43.1% females; age range 15–69 years; mean age 58.4 ± 9.2 years). International Physical Activity Questionnaire (IPAQ) short form was used to measure PA. Total MET-min week−1 of PA were calculated and participants were divided into two categories according to American Diabetes Association PA guidelines: (i) <600 MET-min week−1. (ii) At least 600 MET-min week−1. Diabetes and cataracts were self-reported in response to the questions ‘Have you ever been diagnosed with diabetes/cataracts?’ Participants also reported other variables including age, gender, marital status, living as a couple, education, smoking, alcohol consumption and obesity. Statistical analysis was performed with SPSS 23.0. Results The overall prevalence of cataract was 14.0% and the overall prevalence of people doing <600 MET-min week−1 of PA was 35.4%. The prevalence of cataract was significantly lower in those doing more PA (12.1% vs. 17.5%; P = 0.016). Those without cataracts were significantly more active than those with cataracts (1846.8 vs. 1289.4 MET-min week−1; P = 0.001). The adherence to American Diabetes Association PA guidelines was significantly higher in those without cataracts (66.1% vs. 55.6%; P = 0.016). Conclusions Interventions to promote PA targeting people with both diabetes and cataracts are warranted.
Purpose: The aim of the present study was to assess the association between levels of physical activity (PA) and presence of cataracts in people aged 15-69 years residing in Spain. Methods: Cross-sectional data from the Spanish National Health Survey 2017 were analysed (n = 17,777 ≥15 years; 52% females; self-weighting sample). The International Physical Activity Questionnaire (IPAQ) short form was used to measure PA. Total PA MET-minutes/week were calculated, and participants were divided into two categories: 1) Less than 600 MET-minutes/week. 2) At least 600 MET-minutes/week, equivalent to meeting current PA recommendations. Cataracts were self-reported in response to the question ''Have you ever been diagnosed with cataracts?". Multivariable logistic regression was used to assess associations overall and by age groups (15-49, 50-64 and 65-69 years; 15-49 and 50-69 years). Covariates included in the analysis were: sex, education, BMI (Body Mass Index), multimorbidity, smoking, and alcohol consumption. Results: The overall prevalence of cataract was 3.7%, and the overall prevalence of participating in less than 600 MET-minutes/week of PA was 30.2%. In the adjusted overall analysis, less than 600 MET-minutes/week of PA was associated with significantly higher odds for cataract: OR = 1.324 (95% CI = 1.116-1.571). Age-stratified analyses showed that the association between PA and cataract was significant only in the age groups of 65-69 years and 50-69 years. Conclusions: A significant association between PA and cataract was observed in people aged 15-69 years residing in Spain. Considering the impact on health and quality of life due to reduced PA in people with cataract, at least 600 MET-minutes/week activity should be promoted.
The aim of this study was to analyze the impact of physical activity, BMI, sociodemographic and life-style factors on the risk of diabetes in Ghana. We analyzed data from 9,511 Ghanaian adults that had participated in Waves 0 and 1 of the World Health Organization Study on Global Ageing and Adult Health. To assess diabetes participants were asked: “Have you ever been diagnosed with diabetes (high blood sugar)?”. The impact of nine exposure variables (physical activity, BMI, sex, age, marital status, education, smoking, alcohol intake, and fruit and vegetables consumption) on the risk of diabetes was analyzed with chi-square tests and multivariate regression analyses, separately in each wave to observe the evolution of diabetes risk factors in Ghana. In both adjusted and unadjusted analyses, the exposure characteristics significantly associated (p<0.05) with dia-betes were < 600 MET-minutes/week of physical activity (wave 1), obesity (wave 0), female sex (wave 1), age ≥ 60 years (waves 0 and 1) and education (wave 1). Therefore, these factors should be taken into account to develop public health strategies to reduce diabetes in Ghana. Considering the results of this study, an adequate strategy might be the implementation of physical education programs in people with obesity, women and older adults from Ghana. El objetivo de este estudio fue analizar el impacto de la actividad física, del IMC y de factores sociodemográficos y de estilo de vida sobre el riesgo de diabetes en Ghana. Analizamos datos de 9511 ghaneses adultos que habían participado en las Fases 0 y 1 del Estudio de la Organización Mundial de la Salud sobre el Envejecimiento Global y la Salud de los Adultos. Para evaluar la diabetes, se preguntó a los participantes: "¿Alguna vez le han diagnosticado diabetes (nivel alto de azúcar en la sangre)?". El impacto de nueve variables de exposición (actividad física, IMC, sexo, edad, estado civil, educación, tabaquismo, ingesta de alcohol y consumo de frutas y verduras) sobre el riesgo de diabetes se analizó con pruebas de chi-cuadrado y análisis de regresión multivariante, por separado en cada fase para observar la evolución de los factores de riesgo de diabetes en Ghana. Tanto en el análisis ajustado como en el no ajustado, las características de exposición asociadas significativamente (p<0,05) con la diabetes fueron < 600 MET-minutos/semana de actividad física (fase 1), obesidad (fase 0), sexo femenino (fase 1), edad ≥ 60 años (fases 0 y 1) y educación (fase 1). Por lo tanto, estos factores deben tenerse en cuenta para desarrollar estrategias de salud pública para reducir la diabetes en Ghana. Considerando los resultados de este estudio, una estrategia adecuada podría ser la implementación de programas de educación física en personas con obesidad, mujeres y adultos mayores de Ghana.
The main purpose of this study was to investigate the differences in glycaemic reaction in response to various physical activities in 20 young boys (14.4 ± 1.6 years) with type 1 diabetes mellitus (T1DM) and with either vitamin D deficiency or with suboptimal levels of vitamin D. Participants were divided into two groups (deficiency group-DG, n = 10; suboptimal group-SG, n = 10) according to their vitamin D levels. All patients performed aerobic and mixed (aerobic-anaerobic) physical efforts. During the exercise, the respiratory responses and glucose levels were monitored. Biochemical blood analyses were performed before each physical effort. The oxygen consumption was not significantly lower in SG during both aerobic and mixed effort (4.0% and 5.6%, respectively). The glycated haemoglobin (HbA1c) level was higher by 6.1% and the total daily dose of insulin (DDI) was higher by 18.4% in the DG. The differences were not statistically significant. Patients with lower vitamin D levels demonstrated an insignificantly higher glycaemic variability during days with both aerobic and mixed exercises. An appropriate vitamin D concentration in T1DM patients' blood may constitute a prophylactic factor for hyperglycaemia during anaerobic training and hypoglycaemia during aerobic training.
