Do non-responders to resistance training exist in professional sport?

Resistance training (RT) is the most popular form of exercise that exerts several benefits (muscle hypertrophy and strength). Furthermore, we are witnessing several athletes competing at the highest level of their respective sport have undergone an enormous physical transformation. Nonetheless, lack of RT training, especially after a long detraining period, causes loss of muscle mass, and consequently, a decreased muscle strength, power, and lower muscle activation, and consequently, performance deterioration. In light of these facts, several authors recently have arisen the existence of responders and non-responders to RT. In order to improve athletic performance, the scientific community has tried to define the right RT method to be applied with athletes. In this regard, complex training compared to traditional training methods is reported to be a useful method providing superior benefits for improving athletic performance. With this editorial we encourage the research community to investigate this very interesting and complex matter, making the picture clearer and giving the opportunity to the athletic community to adjust RT programs based on the individual needs in order to maximize the outcome

Is bodyweight affecting plantar pressure distribution in children? An observational study

The aim of this study is twofold: Firstly, to investigate the plantar pressure distribution differences in children coming from 4 different weight categories and secondly to analyze the presence of sex-related plantar pressure distribution differences. Overall, 416 children, aged 7 to 12 years old were randomly selected from 6 different local schools, and voluntarily participated in the study. Two hundred twenty six of them were men, while 190 were women (mean age: 9.93±1.02 years; height: 1.39±0.8m; body mass: 37.76±10.34kg; BMI: 19.24±4.02kg/m2). Based on the body mass index (BMI) the sample was grouped in the following categories: Underweight (UW); normal weight (NW); overweight (OW), and obese (OB). Besides, the plantar load distribution parameters (total plantar load distribution and load distribution in forefoot and rearfoot) were assessed employing freeMed Maxi; Sensor Medica device. Shapiro-Wilk test was used to test the data distribution. Between-groups comparisons were conducted using Mann-Whitney U test, or using Kruskal-Wallis test associated with pairwise comparisons. There were significant differences in load distribution between weight categories, with (OW) and (NW) being significantly different with (O), P=.03 and P=.04, respectively. No significant differences were found on load distribution on the rearfoot and forefoot between categories. The sex effect, particularly among boys, revealed a different pattern of load distribution among (O) compared with other categories. This effect was not detected among women. Different profile of load distribution on the rearfoot and forefoot between boys and girls was found, with girls bearing significantly more weight in the right rearfoot compared with boys (P=.001). It can be concluded that the weight status of the children can affect the plantar load distribution, with obese category being different from (NW) and (OW). Additionally, the sex plays a role when it comes to the load distribution in different regions of the foot. Moreover, since the young age, due to growth and development process, is accompanied with anatomical foot changes which might be affected from numerous factors, assessing plantar pressure distribution in young children results to be a quite complicated matter

Sport intervention programs (SIPs) to improve health and social inclusion in people with intellectual disabilities: A systematic review

Inactivity is a major issue that causes physical and psychological health problems, especially in people with intellectual disability (ID). This review discusses the beneficial effects of sport intervention programs (SIPs) in people with ID, and aims to provide an overview of the scientific literature in order to identify the main factors influencing the participation of people with ID in SIPs. Twelve papers were analyzed and compared. The results show a large variety in examined SIPs, concerning participants’ age and disability, intervention characteristics and context, as well as measures and findings. The main factors essential for people with ID partaking in SIPs appeared to be suitable places for the SIP development, adequate implementation of physical activity (PA) programs in school and extra-school contexts, education, and the training of teachers and instructors. The literature review highlights the relevance of using SIPs in order to improve physical and psychological health, as well as increase social inclusion in populations with ID. SIPs should be included in multifactor intervention programs. Nevertheless, the need is recognized for stakeholders to adopt specific practice and policy in promoting social inclusion in order to organize intervention strategies which are able to provide quality experiences in sport and physical activity for people with ID

The effect of different government restrictions in physical activity levels and exercise preferences during COVID-19 pandemic in Kosovan population

The purpose of the current study was two-fold; firstly, to investigate the effect of two different government restrictions in PA levels expressed as energy expenditure (MET-minutes/week), and secondly to investigate personal exercise preference choices. 1633 participants (age range: 13-63 years; mean: 24.70±9.33 years; body height: 172±10.57 cm; body mass: 69.10±13.80 kg; BMI: 23.09±3.63 kg/m2) were enrolled in the study. A cross-sectional study design was implemented using an online questionnaire, including an adapted version of the International Physical Activity Questionnaire-Short Form (IPAQ-SF). The data concerning PA levels during pandemic were collected under the restriction measures of the government, whereas, PA levels before the pandemic were collected retrospectively. To analyse the data Mann-Whitney was used to analyse the data. Significant differences in MET-min/week between pre and during conditions for both types of government restrictions measures (p\u3c000.1). Likewise, the MET-min/week was significantly higher (p\u3c000.1) during the 1st type of home confinement compared to the 2nd one. As for the % of personal preferences on being engaged in PA, 71.03% used to exercise alone, 10.83% in couple, 8.26% in small groups and 9.85% didn’t prefer to respond. COVID-19 restrictions decreased PA levels and MET-min/week among Kosovan population, in both times from different government measures, with higher decrease on the second resections. As for the exercise personal preferences, Kosovan people preferred on being alone while exercising

A single bout of physical exercise does not affect young adults' executive functions

Study aim. The purpose of the current study is to determine the impact of single bouts of physical exercise of different duration and intensity on young adults' executive functions. Material and methods. The study employed 81 participants (37 females, 44 males) ranging between 19 and 39 years (mean age: 24.6 ± 4.08 years; mean height: 168 ± 9.67 cm; mean weight: 67.2 ± 13.0 kg). The executive functions were assessed through the Stroop task, the Tower of London test, and the Corsi block test. Participants were randomly assigned to one of the three experimental conditions (30-second Wingate test condition, an incremental intensity exercise test, and a submaximal constant-intensity test) or the control group. Results. For all the conditions, repeated measures ANOVA revealed a significant effect of time on executive function performances, meaning that participants improved their performance between pre-test and post-test, while the interaction time x activity was in the expected direction but nonsignificant. Conclusions. Apparently, a single, brief, high-intensity bout of exercise has no effects on young adults' cognitive functions, but the same experiment should be replicated with a bigger sample

Exercise with TENS does not augment gains in balance and strength for dancers

Electrical stimulation modulates sensory feedback and improves motor performance, at least for individuals with compromised sensorimotor function. The purpose of this study was to determine the effectiveness of a 4-wk intervention with transcutaneous electrical nerve stimulation (TENS) at improving strength and balance in dancers. Nineteen dancers completed a timed, single-leg balance test, the Y-balance test, and contractions with the hip flexor and knee extensor muscles to assess maximal strength and force steadiness. They completed 4-wks of moderate-intensity bodyweight exercises (3x/wk) and were pseudo-randomized to either a Treatment or Sham group in a single-blind design. The Treatment group received constant TENS over the hamstring muscles during the exercises, whereas the Sham group was exposed to a brief TENS current. The data were pooled due to few significant between-group differences from before to after the intervention. Most outcome measures significantly improved: hip extensor muscles were stronger (P ≤ 0.01), time stood on a single-leg with eyes closed increased (P = 0.02), and the distance reached during the Y-balance test increased (P ≤ 0.001). The improvement in scores on the Y-balance test exceeded the minimal clinically significant change. Twelve sessions of moderate-intensity bodyweight exercises improved muscle strength and balance in experienced dancers. The addition of TENS, however, did not augment the gains in function

Individualized analysis of skin thermosensory thresholds and sensitivity in heat-sensitive people with multiple sclerosis

We investigated whether and how multiple sclerosis (MS) alters thresholds for perceiving increases and decreases in local skin temperature, as well as the sensitivity to progressively greater temperature stimuli, amongst heat-sensitive people with MS. Eleven MS patients (5 M/6 F; 51.1 ± 8.6 y, EDSS 5.7 ± 1.9) and 11 healthy controls (CTR; 7 M/4 F; 50.3 ± 9.0 y) performed warm and cold threshold tests on a hairy skin site, on both sides of the body. They also underwent a thermosensitivity test where they rated (visual analogue scale) perceived magnitude of 4 local skin stimuli (i.e. 22, 26, 34, 38°C). Individual thresholds and slopes of linear regression for thermosensitivity were z-transformed for each MS patient, and used to determine individual thermosensory abnormalities. When considering both threshold and thermosensitivity, six out of our 11 heat-sensitive patients (54.5%) exhibited skin thermosensory abnormalities. Those abnormalities varied amongst patients in terms of type (threshold vs. thermosensitivity), quality (warm vs. cold), location (left vs. right side of the body) and extent. Each of those six patients presented unique thermosensory profiles. While some patients experienced thermosensory loss in both thresholds and sensitivity and on both sides of the body, others experienced cold thermosensory loss on one side of the body only. The observed individual variability in thermosensory function among heat-sensitive MS patients highlight the need for a patient-centered approach to assessing thermosensory dysfunction and its potential implications for heat stress vulnerability in this patient group

Treatment with electrical stimulation of sensory nerves improves motor function and disability status in persons with multiple sclerosis: A pilot study

Declines in motor function are closely associated with decreases in sensory function in multiple sclerosis (MS). The purpose of our study was to assess the changes in motor function and disability status elicited by transcutaneous electrical nerve stimulation (TENS) to limb muscles of individuals with MS. Fifteen persons with MS and 11 age-matched healthy controls were evaluated before and after receiving 9 treatment sessions during which TENS was applied over the tibialis anterior and rectus femoris muscles of each leg, and over the median nerve and the thenar eminence of each hand. Each evaluation session involved completing two questionnaires (fatigue and walking limitations) and assessing walking performance (2-min test and 25-ft test), dynamic balance (chair-rise test), manual dexterity (grooved pegboard test), and muscle function of hands and legs (strength and force steadiness tests). The MS group exhibited improvements in the 25-ft test (P = 0.001), 2-min test (P = 0.002), chair-rise test (P = 0.008), grooved pegboard test (P = 0.008), and reductions in the self-reported levels of fatigue and walking limitation scores (P = 0.02, d = 0.52; P = 0.008, r = 0.50 respectively). In contrast, there were no statistically significant changes in the Control group. There were no significant changes in either muscle strength or force steadiness for either group. TENS elicited significant improvements in motor function and self-reported disability status in persons with MS. Some improvements reached clinically meaningful levels
