The existing strength training fitness products have the problems of single-use group and function. First of all, this paper takes the universal design as the research criterion, finds out the design pain point of the product to realize the strength training generalization, and proposes to use water as the medium to solve the problems of different groups when carrying out strength training because the products can not meet the different training intensity, universal safety, and training parts. Then, the products can be generalized to different groups and their diversified training needs. Finally, the design scheme is analyzed qualitatively and quantitatively, and compared with the best strength training universal products on the market, so as to verify that water as the medium is feasible for effectively realizing the product generalization in different groups and diversified training needs.

Dynamic Strength Training

When added to endurance training, dynamic strength training leads to significantly greater improvements in peripheral muscle strength and power output in patients with cardiovascular disease, which may be relevant to enhance the patient’s prognosis. As a result, dynamic strength training is recommended in the rehabilitative treatment of many different cardiovascular diseases. However, what strength training intensity should be selected remains under intense debate. Evidence is nonetheless emerging that high-intensity strength training (≥70% of one-repetition maximum) is more effective to increase acutely myofibrillar protein synthesis, cause neural adaptations and, in the long term, increase muscle strength, when compared to low-intensity strength training. Moreover, multiple studies report that high-intensity strength training causes fewer increments in (intra-)arterial blood pressure and cardiac output, as opposed to low-intensity strength training, thus potentially pointing towards sufficient medical safety for the cardiovascular system. The aim of this systematic review is therefore to discuss this line of evidence, which is in contrast to current clinical practice, and to re-open the debate as to what dynamic strength training intensities should actually be applied.

This is the first study to document the training and tapering practices of elite CrossFit athletes. Seventy-two CrossFit athletes (39 females, 33 males) (mean ±SD; 26.5 ± 3.6 y, 167.1 ± 9.5 cm, 74.5 ± 12.7 kg, 12.8 ± 6.5 y general training, 5.4 ± 1.7 y CrossFit training) who competed at the “Regionals” level or higher in the 2018 CrossFit Games season completed a self-reported 5-page online survey. Almost all athletes (98.6%) tapered before important competitions. Taper length was 5.4 ± 2.7 days, with the step and linear tapering styles being most commonly utilised. Strength training volume peaked 5.1 ± 4.6 weeks before competition, whereas conditioning training volume peaked 4.0 ± 4.4 weeks before competition. Strength training intensity peaked 3.1 ± 2.4 weeks before competition, whereas conditioning training intensity peaked 2.8 ± 2.2 weeks before competition. Almost all athletes (90.0%) reduced training duration during tapering, but changes to frequency and intensity were mixed. Training volume decreased by 41.2 ± 15.5% during the taper, all training ceased 2.0 ± 1.1 days before competition. Tapering was performed to achieve peak performance, recover (physically and psychologically), and reduce feelings of fatigue. Poor results from tapering were experienced when athletes tapered for too long or insufficiently. This observational data may be valuable for coaches and athletes engaged in CrossFit as well as other sports with concurrent training and competition demands.

At the Olympic level, optimally distributing training intensity is crucial for maximizing performance. Purpose: The authors evaluated the effect of training-intensity distribution on anaerobic power as a substitute for 1500-m speed-skating performance in the 4 y leading up to an Olympic gold medal. Methods: During the preparation phase of the speed-skating season, anaerobic power was recorded periodically (n = 15) using the mean power (in watts) with a 30-s Wingate test. For each training session in the 4 wk prior to each Wingate test, the volume (in hours), training type (specific, simulation, nonspecific, and strength training), and the rating of perceived exertion (RPE; CR-10) were recorded. Results: Compared with the 8 lowest, the 7 highest-scoring tests were preceded by a significantly (P < .01) higher volume of strength training. Furthermore, the RPE distribution of the number of nonspecific training sessions was significantly different (P < .01). Significant (P < .05) correlations highlighted that a larger nonspecific training volume in the lower intensities RPE 2 (r = .735) and 3 (r = .592) was associated positively and the medium intensities RPE 4 (r = −.750) and 5 (r = −.579) negatively with Wingate performance. Conclusion: For the subject, the best results were attained with a high volume of strength training and the bulk of nonspecific training at RPE 2 and 3, and specifically not at the adjoining RPE 4 and 5. These findings are surprising given the aerobic nature of training at RPE 2 and 3 and the importance of anaerobic capacity in this middle-distance event.
