Six male professional footballers (mean ± standard deviation [SD]; 26 ± 2 years, 79.0 ± 4.9 kg, 1.82 ± 0.05 m) participated. Heart rate variability (HRV) was recorded using a smartphone application prior to the daily training sessions (247 training sessions [41.17 ± 7.41 per player]). External TL was monitored during training using global positioning system devices. Linear mixed models were used to examine variations in HRV and TL across the study period and to determine relationships between HRV and TL. Differences in TL and HRV were expressed as standardised effect sizes (ES) ± 90% confidence limits. Changes in HRV (outcome) were expressed as the expected change for a 2-SD change in TL (predictor). Across the study period, all external TL measures varied substantially, demonstrating weekly fluctuations in load (ES range = 0.00-7.40). The relationship between morning HRV and external TL ranged from −0.10 for distance and 1.89 for equivalent distance index (EDI). Overall, EDI demonstrated the strongest relationship with morning HRV; therefore, EDI and smartphone-derived HRV may provide an indicator of readiness to train within elite soccer.

METHODS: We collected fasting blood samples from 14 male collegiate students with sedentary life style. Plasma AST, alanine aminotransferase (ALT), creatinine and red blood cell related parameters were measured. Based on their baseline AST levels subjects were divided into high-AST and low-AST groups. All participates were asked to complete the acute resistance exercise with intensity of 85% maximal muscle strength, and then blood samples were collected immediately after exercise. RESULTS: High-AST group had higher ALT level (31.57±3.92 > 16.57±0.95 mg/dl) in resting status. After acute resistance exercise, the changes of red blood cell distribution width (RDW), mean corpuscular volume (MCV) and creatinine levels were significantly greater in high-AST group compared to low-AST group (RDW: 0.47±0.24 >-0.57±0.35 %; MCV: 0.30±0.24 >-0.34±0.28 fl; the change of creatinine: 0.10±0.03 > 0.03±0.02 mg/dl). Moreover, the changes of mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were meaningfully lower in high-AST group (MCH:-0.16±0.12 < 0.03±0.11 pg; MCHC:-0.30±0.21 < 0.14±0.21 g/dl). CONCLUSIONS: Our findings suggest that plasma AST level may be a possible predictor in influencing the changes of red blood cell related parameters after intense exercise. The possible reasons may be linked with the antioxidant defense system and renal excretive function.

METHODS: Thirty-one active college age students (19.4 ± 1.4 y and 65.2 ± 11.0 kg) were divided into the ICT and SB groups, each of which completed various medicine ball throws, crunches, and Russian twists. Subjects trained 3 d.wk-1 for 3 wk; medicine ball weight and repetitions increased during the program's midpoint. Changes in core power and strength were measured across time with the Front Abdominal Power Throw (FAPT) and a Cybex dynamometer. Data were analyzed using repeated measures ANOVAs. Dependent t-tests were used to examine changes across time within groups. RESULTS: The ANOVAs revealed no significant main effects between the time points or groups for any dependent variable. The dependent t-tests revealed that SB training significantly increased Cybex flexion and extension power by 2.2% (138.3 ± 38.1 to 141.4 ± 37.6; p=0.047) and 5.6%; (118.3 ± 49.2 to 124.9 ± 50.8; p=0.018), respectively, while ICT training produced no significant changes. A significant interaction was found for flexion power (p=0.036), indicating opposing trends between the two groups across time. A similar relationship was found for flexion work, but the interaction only approached significance (p=0.059). CONCLUSION: The ICT did not improve core function relative to the SB. This study focused on unstable training, but using more weight on the device, thereby increasing stability and resistance, may alter outcomes.
