The use of the cell phone for more than two hours a day seemed to be a risk factor for alcohol and tobacco consumption in insufficiently active adolescents.
We found a high prevalence of cell phone use and a worrying prevalence of alcohol and tobacco consumption by adolescents. The use of the cell phone for more than two hours a day seemed to be a risk factor for alcohol and tobacco consumption in insufficiently active adolescents.
Some methods such as ergo nutritional aids, cooling or massage among others could improve recovery in combat sports (CS). The effects, doses, duration, and timing of these methods remains unknown. Nowadays, there is no clear consensus regarding the recovery strategies and it is necessary to understand the type of fatigue induced in CS and its underlying mechanisms. The main aim of this article is to review the update literature related to recovery strategies in CS.
A literature search was conducted following preferred reporting items for review statement on the topic of "combat sports," "recovery," "nutrition," "fatigue," "ergogenic aids," "weight cutting" and "hydration."
The initial search of the literature detected 369 articles about CS. Later, 307 were excluded after being determined unrelated to recovery or after failure to fulfill the inclusion criteria. Of the 80 included articles, 19 satisfied the final inclusion criteria.
To optimize CS performance, adequate recovery is required during trainieep and rest) therapies have also been shown useful. This narrative review elucidates the important role of recovery techniques in CS.
The Pilates exercises are popular for muscle conditioning among women. However, the effects on conditioning of healthy non-active adult women due to Pilates practicing are not fully explained. The aim of this randomized controlled trial was to assess the effects of equipment-based Pilates exercises on the percentage of body fat, weight, body mass index (BMI), functional capacity, and quality of life of adult healthy women.
Seventy-eight non-active women were randomly assigned to 2 groups (Pilates or Control). The Pilates group performed a total of 16 exercise sessions (60 minutes each, performed twice a week for 8 consecutive weeks). The control group was instructed to perform no exercise. Percentage of body fat (DXA scans), weight, BMI, distance covered in the incremental shuttle walk test, maximal oxygen uptake (VO<inf>2max</inf>), and quality of life (SF-36 scores) were analyzed.
There were no significant between-group differences at baseline, but significant group-by-time interaction was observed for Pilates group postintervention. Higher distance covered (P=0.01), VO<inf>2max</inf> (P=0.04), and quality of life (P=0.04) were observed after the intervention compared to the control group. No differences were observed for body composition.
Two months of equipment-based Pilates training improved functional capacity and quality of life in healthy adult women.

Backward extrapolation technique (BE) was used to estimate V̇O<inf>2</inf> from postexercise measuring, eliminating oronasal mask (OM) during the efforts. Despite its advantage, literature presents discrepancy in applied methods. Thus, the first aim of this study was to compare different mathematical criteria to estimate values of V̇O<inf>2</inf> during a supramaximal effort (V̇O<inf>2PEAK</inf>), while the second aim was to verify the effects of OM on cycling performance.
Twenty-four male cyclists (35±6 years, 81.3±8.9 kg, 180±6 cm) performed three days of tests, with at least 24 h of interval between each test. Firstly, a graded exercise test was applied to determine V̇O<inf>2max</inf> and your correspondent intensity (MAP). The second and the third day were destined to supramaximal efforts at 120% of MAP, performed with (Supra<inf>mask</inf>) and without (Supra<inf>be</inf>) oronasal mask (OM) in a randomized order. After Supra<inf>be</inf>, OM was coupled, and BE was applied. Sixty-six values of V̇O<inf>2</inf> were obtained based on a linear regression fitting.
V̇O<inf>2peak</inf> can be estimated using different curve lengths. However, only curves between 20 and 60 s with extrapolation to 3 s or lesser shows at least one consistent criterion. The 60 s curve extrapoled to -3 s was the most accurate criteria (P=0.723; ES=-0.055; r=0.824; Bias=-0.36 and LoA=7.72 mL.kg.min
). Performance was not impaired with OM and was similar in both condition (P=0.84, ES=0.04).
We conclude that it was possible to accurately estimate V̇O<inf>2</inf> values of a supramaximal effort without any respiratory apparatus with a time-efficient analysis. click here Therefore, we recommended the use of a 60 seconds V̇O<inf>2</inf> curve analysis with a negative extrapolation for 3 seconds.

The purpose of this study was to characterize trail running injuries within a cohort of Portuguese male and female recreational trail running athletes.
The study was retrospective (12 months), with data collected through an online survey. A total of 719 athletes participated (529 male and 190 female, average age 38.01±7.78 years). A valid questionnaire was used to collect 1) demographic information; 2) general information; 3) training typology; 4) physical information; 5) injuries (body location, number, type, reason, treatment, time without practice); and 6) general information concerning the effects of injuries on respondents' daily lives.
The results revealed that 87.8% of the sample contracted an injury resulting from this practice, with the toenails (24.8%), knees (17.5%), and ankles (14.5%) being the most-often reported locations of injuries and blisters (20%), irritation (chafing) (14%), superficial wounds (12%), sprains (11%), and iliotibial band syndrome (7%) being the most common injuries. The result of 10.
