Purpose: To compare the training-volume (TrV) distribution of Russian international-level male biathletes, female biathletes, and cross-country skiers (XC) during an annual cycle. Methods: Day-to-day TrVs were recorded and averaged for a 5-year period for male biathletes (n = 6), female biathletes (n = 8), and XC (n = 14) with VO2max values of 77.7 (3.8), 64.6 (1.9), and 79.4 (3.5) mL·min−1·kg−1, respectively. Results: The volumes of low- and moderate-intensity endurance training and all types of nonspecific endurance and strength training gradually decreased toward the competition period. However, the volumes and proportions of high-intensity endurance training and specific exercises (roller skiing, skiing, and shooting during high-intensity endurance training) increased by the time of the competition period. The total volume of training, volumes of low- and moderate-intensity endurance training, moderate- and high-load strength training (70%–95% 1RM), and power/speed loads did not increase gradually but reached their maximum immediately after a short stage of initial training. All teams employed the “pyramid” model of intensity distribution. Compared with the biathletes, XC demonstrated a larger (P < .01) annual volume of endurance training (~190 h), low-intensity endurance training (~183 h), and strength training (~818 sets). They also engaged in more upper-body and core-strength exercises (~769 sets), and they reached their maximum aerobic TrVs in June, while the biathletes reached theirs in July. Conclusions: In recent decades, the traditional model of periodization has been altered. The Russian XC and biathletes had significant differences in TrVs.

The purposes of this study were to evaluate the effect of an exercise regimen for undergraduate music majors at a university, and to determine whether a short-term, moderate-intensity program designed to assist in their preparation for the athletic task of playing an instrument for many hours a day could be incorporated into their timetables and show strength gains. In this study, 18 volunteer university undergraduate music majors were randomly allocated into either six weeks of strength training or six weeks of endurance training of proximal upper-limb and trunk muscles. All subjects were measured over a six-week control period prior to the exercise period. Tests using both physical and self-report data were repeated on three separate occasions to determine whether training produced any effects over this period, and which form of training was the more effective. Physical testing data were collected by an independent tester who was blinded to the study condition. These data included Cybex dynamometer testing in two planes of shoulder motion, field measurements, and timing an isometric 90-degree forward flexion arm hold. Questionnaires were used to gather data on the frequency and severity of performance-related musculoskeletal disorders and on the perceived exertion of playing. Results indicated that the program produced significant strength gains in both field measurements and dynamometer testing in both exercise groups. While all field measurements of the actual exercises performed increased significantly over the exercise period, the dynamometer results showed a significant effect of the exercise program on the horizontal plane only, suggesting this group of musicians took a task-specific view of the exercises and focused more on their application of horizontal exercises, seeing the relevance in relation to playing an instrument. Vertical isokinetic measurements remained unchanged. Perceived exertion of playing was significantly reduced, with endurance training significantly better than strength training for achieving this result.

BACKGROUND: Combining strength training (ST) with unstable surfaces (US) is a promising complementary approach to traditional ST to optimize muscle strength and balance in different populations. OBJECTIVE: To evaluate the effects of traditional ST and ST+US on grip strength, flexibility and quality of life in older women. METHODS: Fifty-eight older women were randomly assigned into ST (n= 22), ST+US (n= 22) or control (n= 14) group. Exercise groups performed whole-body, moderate-intensity strength exercises, thrice a week during 24-weeks. ST+US participants performed the same exercise prescription progressively adding unstable surfaces and devices. Dependent variables (grip strength, flexibility and health-related quality of life) were measured at baseline, 12-weeks and after 24-weeks of intervention. RESULTS: At completion of 24-weeks, compared with control group, traditional ST promote flexibility gains [SRT =+ 5.42 cm (95% CI = 1.01 to 9.83)]. Both training regimes improved quality of life [ST =+9.50 (95% CI = 1.80 to 17.20); ST+US =+ 15.23 (95%CI = 7.37 to 23.08). No significant between-group difference was observed for grip strength at completion of the intervention. CONCLUSION: Traditional strength exercises were effective to improve flexibility and health-related quality of life among healthy older women. Combining unstable devices with traditional exercise did not provide additional gains in order to promote flexibility and quality of life.

Abstract Background Skeletal muscle is very sensitive to extracellular and intracellular signaling evoked by contractions from endurance and resistance exercise. The aim of this study was to compare the effects of moderate- and high-intensity endurance and resistance training on the serum myostatin (MSTN) and insulin-like growth factor (IGF-1) levels in older rats. Materials and methods Fifty old Wistar male rats (23 months old) were randomly divided into four experimental and one control groups, including moderate-endurance training (MET) (n = 10), high-intensity endurance training (EHT) (n = 10), moderate-intensity resistance training (MRT) (n = 10), high-intensity resistance training (HRT) (n = 10), and control group (C) (n = 10). Seventy-two hours after the last exercise session, euthanasia of the rats were rendered unconscious and direct blood samples were collected. Serum IGF-1 and MSTN concentration were measured using the enzyme-linked immuno sorbent assay (ELISA) method. The statistical analysis was performed using one-way analysis of variance (ANOVA) test with a significance level of p ≤ 0.05. Results There was a significant reduction in MSTN and an increase in IGF-1 concentrations was observed between IGF-I levels in high and moderate resistance and endurance training. However, no significant difference was observed in MSTN levels between groups. Discussion Therefore, it appears that resistance training, especially HRT, is effective to increase growth mediators among older rats.

The Impact

Purpose:To quantify the impact of training-intensity distribution on 10K performance in recreational athletes.Methods:30 endurance runners were randomly assigned to a training program emphasizing low-intensity, sub-ventilatory-threshold (VT), polarized endurance-training distribution (PET) or a moderately high-intensity (between-thresholds) endurance-training program (BThET). Before the study, the subjects performed a maximal exercise test to determine VT and respiratory-compensation threshold (RCT), which allowed training to be controlled based on heart rate during each training session over the 10-wk intervention period. Subjects performed a 10-km race on the same course before and after the intervention period. Training was quantified based on the cumulative time spent in 3 intensity zones: zone 1 (low intensity, <VT), zone 2 (moderate intensity, between VT and RCT), and zone 3 (high intensity, >RCT). The contribution of total training time in each zone was controlled to have more low-intensity training in PET (±77/3/20), whereas for BThET the distribution was higher in zone 2 and lower in zone 1 (±46/35/19).Results:Both groups significantly improved their 10K time (39min18s ± 4min54s vs 37min19s ± 4min42s, P < .0001 for PET; 39min24s ± 3min54s vs 38min0s ± 4min24s, P < .001 for BThET). Improvements were 5.0% vs 3.6%, ~41 s difference at post-training-intervention. This difference was not significant. However, a subset analysis comparing the 12 runners who actually performed the most PET (n = 6) and BThET (n = 16) distributions showed greater improvement in PET by 1.29 standardized Cohen effect-size units (90% CI 0.31–2.27, P = .038).Conclusions:Polarized training can stimulate greater training effects than between-thresholds training in recreational runners.

Chronic Effects

AbstractHigh-intensity functional training (HIFT) has become a popular method in the sports and fitness sector. In contrast to unimodal approaches such as strength or endurance training, it has been hypothesized to induce concurrent adaptations in multiple markers of motor function. However, to date, the effectiveness of HIFT in this regard has not been studied. The present systematic review quantified the chronic effects of HIFT on motor function in healthy individuals. A multilevel meta-analysis with a robust random effects meta-regession model was used to pool the standardized mean differences (SMD) between (a) HIFT and (b) no-exercise (NEX) as well as conventional endurance, resistance and balance training for outcomes of muscle strength, endurance capacity and balance. The influence of possible effect modifiers such as program duration, session duration, age or sex was examined in a moderator analysis. Seventeen papers with moderate to high methodological quality (PEDro scale) were identified. Compared to NEX, HIFT had small to moderate positive effects on endurance capacity (SMD: 0.42, 95% CI 0.07–0.78, p = 0.03) and strength (0.60, 95% CI 0.02–1.18, p = 0.04) but no effect on balance (SMD: − 0.10, 95% CI − 1.13 to 0.92, p = 0.42). Regarding endurance, HIFT showed similar effectiveness as moderate-intensity endurance training (SMD: − 0.11, 95% CI − 1.17 to 0.95, p = 0.75) and high-intensity interval endurance training (SMD: − 0.15, 95% CI − 1.4 to 1.1, p = 0.66). No comparisons of HIFT vs. classical resistance or balance training were found. Moderator analyses revealed no influence of most effect modifiers. However, regarding endurance, females seemed to respond more strongly to HIFT in the comparison to NEX (p < .05). HIFT appears to represent an appropriate method to induce chronic improvements in motor function. While being superior to NEX and non-inferior to endurance training, current evidence does not allow a comparison against resistance and balance training. The impact of possible effect moderators should be further elucidated in future research.

Regular exercise training is recognized as a powerful tool to improve work capacity, endothelial function and the cardiovascular risk profile in obesity, but it is unknown which of high-intensity aerobic exercise, moderate-intensity aerobic exercise or strength training is the optimal mode of exercise. In the present study, a total of 40 subjects were randomized to high-intensity interval aerobic training, continuous moderate-intensity aerobic training or maximal strength training programmes for 12 weeks, three times/week. The high-intensity group performed aerobic interval walking/running at 85–95% of maximal heart rate, whereas the moderate-intensity group exercised continuously at 60–70% of maximal heart rate; protocols were isocaloric. The strength training group performed ‘high-intensity’ leg press, abdominal and back strength training. Maximal oxygen uptake and endothelial function improved in all groups; the greatest improvement was observed after high-intensity training, and an equal improvement was observed after moderate-intensity aerobic training and strength training. High-intensity aerobic training and strength training were associated with increased PGC-1α (peroxisome-proliferator-activated receptor γ co-activator 1α) levels and improved Ca2+ transport in the skeletal muscle, whereas only strength training improved antioxidant status. Both strength training and moderate-intensity aerobic training decreased oxidized LDL (low-density lipoprotein) levels. Only aerobic training decreased body weight and diastolic blood pressure. In conclusion, high-intensity aerobic interval training was better than moderate-intensity aerobic training in improving aerobic work capacity and endothelial function. An important contribution towards improved aerobic work capacity, endothelial function and cardiovascular health originates from strength training, which may serve as a substitute when whole-body aerobic exercise is contra-indicated or difficult to perform.
