Components and adsorption capacities involving baking soda changed golf ball milled biochar for the elimination of methylene glowing blue through aqueous alternatives.

To compare the effectiveness of resistance power training (RPT, training with the individualized load and repetitions that maximize power output) and cycling power training (CPT, short sprint training) in professional cyclists.

The participants (20 [2]y, peak oxygen uptake 78.0 [4.4]mL·kg-1·min-1) were randomly assigned to perform CPT (n = 8) or RPT (n = 10) in addition to their usual training regime for 7 weeks (2sessions/wk). The training loads were continuously registered using the session rating of perceived exertion. The outcomes included endurance performance (8-min time trial and incremental test), as well as measures of muscle strength/power (1-repetition maximum and mean maximum propulsive power on the squat, hip thrust, and lunge exercises) and body composition (assessed by dual-energy X-ray absorptiometry).

No between-group differences were found for training loads or for any outcome (P > .05). Both interventions resulted in increased time-trial performance, as well as in improvements in o strength/power.

The authors investigated the effect of foot cooling (FC) between sets in a leg press pyramid workout with resistance-trained participants.

A total of 12 resistance-trained men (age = 21.8 [0.6]y; training experience = 1.7 [1]y) performed a pyramid workout, including 4 sets of 85% to 90% 1-repetition maximum leg press exercise to exhaustion with interset FC or noncooling in a repeated-measures crossover design separated by 5days. The authors immersed the participants' feet in 10°C water for 2.5minutes between sets.

Two-way repeated-measures analysis of variance revealed that FC elicited significantly higher repetitions and electromyography (EMG) values of the vastus lateralis (simple main effect of condition) than did noncooling (P < .05) in the second (repetitions 11 [3.5] vs 7.75 [3.2]; EMG 63.4% [19.4%] vs 54.5% [18.4%]), third (repetitions 8.9 [3.2] vs 6.4 [2.1]; EMG 71.5% [17.4%] vs 60.6% [19.4%]), and fourth (repetitions 7.5 [2.7] vs 5.1 [2.2]; EMG 75.2% [19.6%] vs 59.3% [23.5%]) sets. The authors also detected a simple main effect of set in the FC and noncooling conditions on repetitions (P < .05) and in the FC condition on the vastus lateralis EMG values. link= CX-5461 ic50 Although the authors observed no time × trial interactions for the rating of perceived exertion, the authors observed main effects on the sets (7.7-9.6 vs 7.9-9.3, P < .05).

Interset FC provides an ergogenic effect on a leg press pyramid workout and may offset fatigue, as indicated by higher repetitions and EMG response, without increasing perceived exertion.

To describe the intensity, load, and performance characteristics of a world-class sprinter competing in the Tour de France (TdF).

Power output (PO) data were collected from 4 editions of the TdF (2013, 2014, 2016, and 2017) and analyzed. Load, intensity distribution in 5 PO zones, and the maximal mean PO for multiple durations were quantified. link2 Stages were divided in accordance with the 4 different editions of the TdF, as well as the 4 different stage types, that is, flat (FLAT), semimountainous (SMT), mountain (MT), and (team) time trials. In addition, based on their location within the stage, mountain passes were further classified as BEGINNING, MIDDLE, or END of the stage.

No differences in load, intensity, and performance characteristics were found when the 4 editions of the TdF were compared. Time trials were associated with higher intensities but a lower load compared to the other stage types. MT showed higher load and intensity values compared to FLAT and SMT stages. FLAT stages were higher in short maximal mean PO (≤1min), whereas MT stages showed higher longer endurance maximal mean PO values (≥20min). In addition, mountain passes situated at the BEGINNING of the stage were completed with a higher PO, cadence, and speed compared with mountain passes situated at the END.

A world-class sprinter sustains a higher load and spends more time in the high-intensity zones when competing in the TdF than previously reported values suggested. To finish the MT stages as efficiently as possible, sprinters adopt a reverse pacing strategy.

To investigate the relationship between prescribed (preDI), perceived (perDI), and actual delivery intensity (actDI) in cricket pace bowling.

Fourteen male club-standard pace bowlers (mean [SD] age 24.2 [3.2]y) completed 1 bowling session comprising 45 deliveries. CX-5461 ic50 The first 15 deliveries composed the warm-up, where participants bowled 3 deliveries each at a preDI of 60%, 70%, 80%, 90%, and 95%. link3 Bowlers reported the perDI after each delivery. link2 The fastest delivery in the session was used as a reference to calculate relative ball-release speed for the warm-up deliveries, with this measure representing the actDI. Ball-release speed was captured by a radar gun.

For perDI, there was a very large relationship with preDI (rs = .90, P < .001). Similarly, for actDI, there was a large relationship with preDI (rs = .52, P < .001). Higher concordance was observed between perDI and preDI from 60% to 80% preDI. A plateau was observed for actDI from 70% to 95% preDI.

The relationship between perDI and actDI was very large and large with respect to preDI, indicating that both variables can be used to monitor delivery intensity against the planned intensity and thus ensure healthy training adaptation. The optimal preDI that allowed pace bowlers to operate at submaximal perDI but still achieve close to maximal ball-release speeds was 70%. Bowling at the optimal preDI may significantly reduce the psychophysiological load per delivery in exchange for a trivial loss in ball-release speed.

This study compared pooled against individualized load-velocity profiles (LVPs) in the free-weight back squat and power clean.

A total of 10 competitive weightlifters completed baseline 1-repetition maximum assessments in the back squat and power clean. CX-5461 ic50 Three incremental LVPs were completed, separated by 48 to 72 hours. Mean and peak velocity were measured via a linear-position transducer (GymAware). Linear and nonlinear (second-order polynomial) regression models were applied to all pooled and individualized LVP data. A combination of coefficient of variation (CV), intraclass correlation coefficient, typical error of measurement, and limits of agreement assessed between-subject variability and within-subject reliability. Acceptable reliability was defined a priori as intraclass correlation coefficient > .7 and CV < 10%.

Very high to practically perfect inverse relationships were evident in the back squat (r = .83-.96) and power clean (r = .83-.89) for both regression models; however, stronger cory profiling as part of their testing and monitoring procedures, an individualized LVP should be utilized over pooled LVPs.

To present a case report of an elite ultra-endurance cyclist, who was the winner and course record holder of 2 distinct races within a 4-month span a 24-hour solo cycling race and a 2-man team multiday race (Race Across America).

The athlete's raw data (cycling power, heart rate [HR], speed, and distance) were obtained and analyzed for 2 ultra-endurance races and 11weeks of training in between.

For the 24-hour race, the athlete completed 861.6km (average speed 35.9km·h-1, average power 210W [2.8W·kg-1], average HR 121 beats per minute) with a 37% decrease in power and a 22% decrease in HR throughout the race. During the 11weeks between the 24-hour race and Race Across America, training intensity distribution (Zone 1/2/3) based on HR was 51%/39%/10%. For the Race Across America, total team time to complete the 4939-km race was 6days, 10hours, 39minutes, at an average speed of 31.9km·h-1. Of this, the athlete featured in this case study rode 75.2hours, completing 2532km (average speed 33.7km·h-1, average power 203W [2.7W·kg-1]), with a 12% decrease in power throughout the race. Power during daytime segments was greater than nighttime (212 [25] vs 189 [18]W, P < .001, ηp2=.189).

This case report highlights the performance requirements of elite ultra-endurance cycling. Although average power was similar when riding for 24hours continuously and 75hours intermittently over 6.5days, there were large differences in pacing strategies and within-day power-output changes.

Dynamic balance exercises are commonly utilized during ankle sprain and chronic ankle instability (CAI) rehabilitation. Blood flow restriction (BFR) has been used to enhance muscle activity during exercise and improve outcomes of traditional rehabilitation exercises in clinical populations.

Examine the effects of BFR on lower-extremity muscle activation during dynamic balance exercises in individuals with CAI.

Crossover study design.

Laboratory.

Twenty-five (N = 25) young adults with a history of CAI.

Participants performed dynamic balance reaching exercises during 2 randomized order conditions, BFR, and control. For each condition, participants performed 2 trials of balance exercises. Each trial included 4 sets (30 × 15 × 15 × 15) of reaches in anterior, posteromedial, and posterolateral directions. For the BFR condition, the authors placed a cuff around the proximal thigh at 80% of arterial occlusion pressure. For the control condition, no cuff was worn.

The authors recorded normalized electroior muscle activation. Individuals with CAI perceived greater postural instability and exertion during dynamic balance exercises with BFR.

Individuals with CAI demonstrated large increases in vastus lateralis and small increases in soleus muscle activation during dynamic balance exercises with BFR. The BFR had no effect on fibularis longus and tibialis anterior muscle activation. link3 Individuals with CAI perceived greater postural instability and exertion during dynamic balance exercises with BFR.

Current international consensus endorses a multimodal approach to concussion assessment. However, the psychometric evaluation of clinical measures used to identify postconcussion performance deficits once an athlete is asymptomatic remains limited, particularly in the pediatric population.

To describe and compare the sensitivity and specificity of a multimodal assessment battery (balance, cognition, and upper and lower body strength) versus individual clinical measures at discriminating between concussed youth athletes and noninjured controls when asymptomatic.

Prospective cohort study.

Hospital laboratory setting.

A total of 32 youth athletes with a concussion and 32 matched (age and sex) noninjured control participants aged 10-18years.

Participants were administered preinjury (baseline) assessments of cognition (Immediate Post-Concussion Assessment and Cognitive Testing [ImPACT]), balance (BioSway), and upper and lower body strength (grip strength and standing long jump). Assessments were readministered when concussed participants reported symptom resolution (asymptomatic time point).
