Adults with an intellectual disability have significantly lower levels of fitness compared with the general population. This study examined the effects of a 13-week theoretically guided, community-based, multicomponent resistance training intervention, resistance training for empowerment, on muscular strength and independent functional performance in 24 adults with an intellectual disability, aged 18–44 years. Twelve participants were randomly allocated to an experimental group and 12 to an active control group. An analysis of covariance revealed that the experimental group had significantly greater increases (p < .05) on the chest press and leg press one-repetition maximum tests and the 6-min walk test from the baseline to postintervention compared with the control group. The experimental group correctly and independently performed a significantly greater number of steps of resistance training exercise tasks than the control group. Marginal significance and large effect sizes were found for the prone plank test and the stair climb test. The resistance training for empowerment was effective in promoting muscular strength and independent functional performance among adults with an intellectual disability.

Background The block phase in the swimming start requires a quick reaction to the starting signal and a large take-off velocity that is primarily horizontal in direction. Due to the principle of specificity of training, there is a potential benefit of performing a greater proportion of horizontal force production exercises in a swimmers’ dry-land resistance training sessions. Therefore, the purpose of this pilot study was to provide an insight into the effects of a horizontal- (HF) vs vertical-force (VF) training intervention on swim start performance. Methods Eleven competitive swimmers (six males (age 20.9 ± 1.8 years, body mass 77.3 ± 9.7 kg, height 1.78 ± 0.05 m) and five females (age 21.4 ± 2.0 years, body mass 67.5 ± 7.4 kg, height 1.69 ± 0.05 m)) completed 2 weekly sessions of either a horizontal- or vertical-force focused resistance training programme for 8 weeks. Squat jump force-time characteristics and swim start kinetic and kinematic parameters were collected pre- and post-intervention. Results Across the study duration, the swimmers completed an average of nine swimming sessions per week with an average weekly swim volume of 45.5 ± 17.7 km (HF group) and 53 ± 20.0 km (VF group), but little practice of the swim start per week (n = 9). Within-group analyses indicated a significant increase in predicted one repetition maximum (1RM) hip thrust strength in the HF group, as well as significant increases in grab resultant peak force but reductions in resultant peak force of the block phase for the VF group. No significant between-group differences in predicted 1RM hip thrust and back squat strength, squat jump force-time and swim start performance measures were observed after 8 weeks of training. Significant correlations in the change scores of five block kinetic variables to time to 5 m were observed, whereby increased block kinetic outputs were associated with a reduced time to 5 m. This may be indicative of individual responses to the different training programmes. Discussion The results of this current study have been unable to determine whether a horizontal- or vertical-force training programme enhances swim start performance after an 8-week training intervention. Some reasons for the lack of within and between group effects may reflect the large volume of concurrent training and the relative lack of any deliberate practice of the swim start. Larger samples and longer training duration may be required to determine whether significant differences occur between these training approaches. Such research should also look to investigate how a reduction in the concurrent training loads and/or an increase in the deliberate practice of the swim start may influence the potential changes in swim start performance.

Abstract Objectives Nutrition is a key element in post-exercise regeneration. Various studies suggest that ingestion of combined carbohydrates and proteins after exercise result in a decrease of inflammatory processes and consequently in an increase of regeneration and physical performance. Recent studies compared the pro-regenerative effects of protein/carbohydrate shakes with the intake of foodstuffs (white bread and high protein cheese) on the skeletal muscle after acute endurance exercise. The aim of this study was to evaluate the influence of a conventional curd/juice shake on the regenerative capacity of soccer players after intensive strength training. Methods Therefore, sixteen young healthy in-season football payers run through a placebo checked double-blind crossover study with two groups. After a standardized training protocol, 3 sets of 12 reps deep back squats and 3 sets of 15 reps drop jumps, the participants ingested either a placebo shake (placebo-group, total calories &lt; 10 kcal) or a conventional shake of 300 g curd and 200 ml grape juice (protein 35.8 g, carbohydrates 43.6 g, fat 0.9 g, total calories 338 kcal). To evaluate the muscle damage effects, serum creatin kinase (CK) as a physiological parameter as well 10 m sprint, counter movement jump (CMJ) and 3RM-squat as functional markers were measured at two time points (t0, t24). In addition, the CK of five players was analysed after a soccer match. Results The results show a positive trend concerning sprint and squat performance in the shake group. Especially in the squat group a significant decrease of performance was observed in the placebo group compared to the shake group (PL: −5.0 kg, P ≤ 05, SH: −3,2 kg, P = .10). In CMJ and CK no difference was observed between the two groups. In both groups, the jump in CMJ decreased and the CK value increased significantly. The increase in CK due to intensive resistance training is also comparable to the muscle damage after a football match. Conclusions In summary, it was found that a quark/juice shake has a positive influence on strength performance in soccer players after intensive strength training. These findings confirm observations from previous studies. However, the positive effects on CK could not be observed in this study. Therefore, further research on conventional foodstuff after resistance training is necessary. Funding Sources No funding.

Purpose To determine whether training duration is a predisposing factor in potential maladaptations in talent development programmes that promote early specialisation in elite youth soccer. Methods Training times and type of 184 elite soccer players, from the under-9 to under-21 age groups (age 9.4 to 18.4 yrs; stature 1.38 to 1.82 m; body mass 32.2 to 76.2 kg) were recorded. Results Total training time progressively increased between the under-9 (268 ± 25 min/week) and under-14 (477 ± 19 min/week) groups with the majority of training time (96.5 ± 3.9%) consisting of soccer training and matches. Total training time then subsequently reduced from under-14 to under-15 (266 ± 77 min/week) groups, with no differences in training time between under-15 and under-21. Only under-15 to under-21 players completed resistance training; this inclusion coincided with a reduction in soccer training and match play when compared to time spent in these activities for younger groups (73.8 ± 3.2% of total training). Conclusion Data suggest that although the majority of training is focused on technical development, the training duration as a whole is unlikely to contribute to potential maladaptations in talent development programmes in elite youth soccer.
