3%). Non-arrhythmic findings (i.e., sinus rhythm or sinus tachycardia) were recorded in 28 athletes (45.9%), whereas 11 (18%) had negative monitoring. Selleck SBE-β-CD In the sedentary group, arrhythmic events were similar for types and frequency to athletes. The diagnostic yield of loop monitoring was 82.8% in the overall population and 82.0% in the athlete's group.

In the management of an athlete symptomatic with unexplained palpitations after 24-hour ECG monitoring and stress test, ELR is an efficient tool to identify major arrhythmic events, which can be present in up to 10% of symptomatic athletes during practice and competition.

The purpose of this study was to analyze the differences between myokine and adipokine factors under stable conditions according to the menstrual cycle (luteal and follicular phases), and investigate the effect of regular resistance exercise on the changes in myokine and adipokine factors according to menstrual cycle in obese female college students.

The study participants were female college students with a body fat percentage of 30% or more (n = 20), divided into two groups luteal phase (n = 12) and follicular phase (n = 8). They performed regular resistance exercise three times a week, 60 minutes daily, for 16 weeks. Parameters measured include body composition via impedance, visceral fat area using computed tomography and myokine and adipokine factors in blood.

Levels of BDNF (p < .05), NGF (p < .01), and adiponectin (p < .01) were significantly increased in the luteal phase group after 16 weeks relative to the baseline values. Leptin (p < .01) was significantly decreased in the luteal phase group after 16 weeks. Weight, body mass index, % fat, and visceral fat area were significantly decreased in both groups after 16 weeks. Muscle mass was significantly increased in both groups after 16 weeks.

Regular resistance exercise affected the reduction in visceral fat area and had a positive effect on body composition, which might be altered favorably by myokines and adipokines. Thus, the timing of blood collection is very important in obese female college students.

The purpose of this retrospective survey was to analyse the prevalence of low back pain (LBP) among Italian adolescent soccer players, and to identify potential risk factors.

Participants were requested to answer an online survey based on the standardized Nordic questionnaires for musculoskeletal symptoms.

Data were obtained from 204 male soccer players aged 14-17 years competing at the national and regional level. More than half of the players had experienced LBP in their lives. One-way ANOVA revealed that the players with LBP were taller, heavier and with a higher BMI (all p values<0.00001). When considering the playing position, ANOVA revealed that 14-15 years-old strikers displayed higher LBP scores than all other roles (all p values<0.05). Accordingly, strikers were exposed to a higher risk of LBP than midfielders (RR=1.48; 95%CI1.10-2.01; p=0.01) and goalkeepers (RR=1.48; 95%CI1.02-2.971; p=0.04), but not defenders (RR=1.23; 95%CI0.93-1.63; p=0.15). Within the 14-15 age-class, strikers were, again, those most exposed to LBP risk (all p values<0.05).

Anthropometric and soccer-related features should be monitored to ensure early identification of potential risk factors for LBP. This information should be considered along with the specific playing position as strikers emerged as the roles most exposed to LBP risk.

The purpose was to compare the effects of 8-weeks resistance training programs (Flywheel Iso-inertial, FW vs Traditional Gravity-Dependent Resistance Training, GD) performed twice a week at the same rate of perceived exertion (RPE), on muscle force and power capacities and physical performance in healthy older participants.

Twenty-four participants were randomly assigned to either FW (male/female 7/5, age 67.1±3.8 yr) or GD (male/female 6/6, age 68.3±3.0 yr) group. Knee extension maximal isometric voluntary contractions (MVC), lower limb maximal explosive power (MEP), six-minute walking distance (6MWT), timed "Up & Go" scores (TUG), metabolic cost of walking (CW) and agonist-antagonist co-contraction time (CCT) during walking were evaluated before and after training.

absolute MEP and MEP normalized for body mass increased only in FW than GD group (+10.8% vs +0.31%, p 0.056, respectively; +14.8% vs +13.9%, p<0.001, respectively). Both training modalities improved MVC to a similar extent (+11.1% in FW vs +13.4% in GD, p<0.001). Analogously, 6MWT distance increased in FW and GD (+5.2 and +5.5%, p<0.041, respectively). No effects of time and training modality were observed on the other parameters.

The study suggests that when FW and GD are administered at the same RPE with FW performed at higher movement speed in the concentric phase, both the trainings generate similar improvements in muscle strength but only the former can promote greater muscle power enhancements than GD in healthy older adults.

Squatting is a core exercise for many purposes. However, there is still controversy surrounding the practice of targeting specific muscle groups when performing the back squat with different stance widths or foot positions. Therefore, this study aimed to assess lower limb muscle activation during different form of back squat when adopting three different foot angles.

Eight male active participants (age 24.0±0.8 years, height 1.80±0.63m and mass 85.8±8.7kg) performed maximal isometric squat, back squat with an overalod of 80% of 1 repetition maximum, and countermovement jump (CMJ) when adopting three foot rotation angles parallel (0°); +10° outward (external rotation); +20° outward (external rotation). We calculated the root mean square of the electromyographic signals recorded from eight participant's dominant leg muscles.

During the descending phase of the back squat, the 20° external foot rotation elicited greater activation of the biceps femoris (+35%; p = 0.027) and gastrocnemius medialis (+70%; p = 0.040) compared to parallel foot. link2 There were no significant differences among the other muscles and exercise conditions.

The +20° foot position increased BF and GasM muscle activity only during the downward phase of the back squat. Strength coaches should consider the present findings when selecting specific resistance exercises aiming to improve athletes' strength and physical fitness.

Soccer has been hypothesized to be an ideal sport to stimulate favorable changes in bone properties due the high-intensity, multidirectional movements performed during play. The purpose of this study was to determine if participation in soccer is associated with enhanced bone properties such as volumetric bone mineral density (vBMD), cross-sectional geometry, and estimated strength in the tibias of young, healthy women.

Twenty female soccer players (20±1 yr) and twenty mass- and height-matched healthy women (21±1 yr) participated in this cross-sectional study. Peripheral quantitative computed tomography (XCT 3000; Stratec Medizintechnik, Pforzheim, Germany) was used to assess bone characteristics, including vBMD, cross-sectional moments of inertia (CSMI), and strength/strain index (SSI) at 14%, 38%, and 66% of the tibial length proximal to the distal end plate. One-way multivariate analysis of variances was run to determine the influence of soccer training history on tibial properties.

Compared to healthy controls, soccer players had approximately 1.5% - 3% lower cortical vBMD but 18.5% - 30% greater CSMI and 16.5% -19% greater SSI at the three cross-sectional sites along the tibial diaphysis (all p < 0.05).

These results suggest that soccer participation is associated with favorable bone cross-sectional geometry and estimates of bone strength. However, randomized controlled intervention trials are needed to confirm whether soccer participation results in favorable bone adaptations in young, healthy adults.

Caffeine enhances muscle glycogen re-synthesis post exercise; however, the next-day effects on recovery are unknown. The present study aimed to examine the effects of carbohydrate (CHO) supplementation with or without caffeine (CAF) 24-h following exhaustive exercise on time trial performance in elite paddling athletes.

Nine highly trained male paddlers (21 ± 2 y) completed three experimental trials in a randomized, double-blind, crossover manner. Following an exhaustive exercise session (20-km timed paddle) participants ingested (i) 0.6 g/kg of carbohydrate (CHO), (ii) 0.6 g/kg of carbohydrate with 6 mg/kg of caffeine (CAF+CHO), (iii) or placebo (PLA), at four time-points (immediately after, and 2, 6, and 12-h post-exercise) in addition to their typical dietary intake. After 24 h, 5 attempts of on-water 500-m paddling time-trial was performed, and the average time was recorded. Blood samples were taken at rest and following both the 20-km and the 5×500 m exercise to determine changes in plasma cortisol, insulin, and glucose.

There was a significant main effect of condition (P<0.001), with post hoc analysis revealing that both CHO conditions (CHO 98.7 ± 2.8 s, P = 0.0003; CAF+CHO 97.9 ± 2.3 s, P = 0.0002) were significantly faster compared to PLA (101.0 ± 3.1 s), however CAF did not augment time trial performance compared to CHO (P = 0.16). link3 There was no significant condition by time interactions for glucose, cortisol, or insulin before and after the 20-km depleting exercise and 500-m time trial.

In elite male paddlers, CHO, independent of caffeine, enhanced time trial performance 24 hours following exhaustive exercise.
